One of the fundamental questions for someone interested in the impact of doubled CO2 is exactly how (1) the greenhouse effect works; and (2) how the enhanced greenhouse effect works. AR4 FAQ 3.1 poses the question: Im going to show their answer to this question in full because the answer does not rise about a…
Although the bulk of photovoltaic devices today are used for purely practical and economic reasons, a potential benefit of photovoltaics is that PV is one of the most environmentally benign of any electricity generating source. The environmental impact of electricity generation, particularly the greenhouse effect, adds an important reason for examining photovoltaics. A brief overview of the greenhouse effect is given below.. The Earths temperature is a result of an equilibrium established between the incoming radiation from the sun and the energy radiated into space by the Earth. The outgoing radiation emitted by the Earth is strongly affected by the presence and composition of the Earths atmosphere. If we had no atmosphere, as on the moon, the average temperature on the Earths surface would be about -18°C. However, a natural background level of 270 ppm carbon dioxide (CO2) in the atmosphere absorbs outgoing radiation, thereby keeping this energy in the atmosphere and warming the Earth. The ...
Greenhouses allow gardeners to grow plants in cold weather. This is because the air inside the greenhouse stays warmer than the outside air. Short wavelength radiation from the sun passes through the glass, warming the interior of the greenhouse. The longer-wavelength radiation emitted does not pass through glass and is trapped in the greenhouse. This, along with the lack of mixing between the inside and outside air, keeps the greenhouse consistently warm.. On a larger scale, the greenhouse effect helps keep our planet warm. Short wavelength radiation from the sun passes through the atmosphere, warming the Earth. The longer wavelength energy is then trapped by certain gases called greenhouse gases. The greenhouse gases most responsible are water vapor, carbon dioxide, methane, and nitrous oxide.. In this experiment, you will use two Temperature Probes to measure and compare the temperatures in model greenhouses under various conditions. In Part I, you will investigate the role of a plastic ...

The third assessment report (TAR) prominently featured[124] a graph labeled "Millennial Northern Hemisphere temperature reconstruction" based on a 1999 paper by Michael E. Mann, Raymond S. Bradley and Malcolm K. Hughes (MBH99), which has been referred to as the "hockey stick graph". This graph extended the similar graph in Figure 3.20 from the IPCC Second Assessment Report of 1995, and differed from a schematic in the first assessment report that lacked temperature units, but appeared to depict larger global temperature variations over the past 1000 years, and higher temperatures during the Medieval Warm Period than the mid 20th century. The schematic was not an actual plot of data, and was based on a diagram of temperatures in central England, with temperatures increased on the basis of documentary evidence of Medieval vineyards in England. Even with this increase, the maximum it showed for the Medieval Warm Period did not reach temperatures recorded in central England in 2007.[123] The MBH99 ...

The outcome of the summit was an agreement adopted by the states parties that called for a large "Green Climate Fund", and a "Climate Technology Centre" and network. It looked forward to a second commitment period for the Kyoto Protocol. The agreement recognizes that climate change represents an urgent and potentially irreversible threat to human societies and the planet, which needs to be urgently addressed by all parties. It affirms that climate change is one of the greatest challenges of our time and that all parties must share a vision for long-term cooperative action in order to achieve the objective of the Convention, including the achievement of a global goal. It recognizes that warming of the climate system is scientifically verified and that most of the observed increase in global average temperatures since the mid twentieth century are very likely due to the observed increase in anthropogenic greenhouse gas concentrations, as assessed by the IPCC in its Fourth Assessment Report. The ...
Arrhenius was referring to a potential modification of what we now call the greenhouse effect. Shortwave solar radiation can pass through the clear atmosphere relatively unimpeded, but longwave infrared radiation emitted by the warm surface of the Earth is absorbed partially and then re-emitted by a number of trace gases-particularly water vapor and carbon dioxide-in the cooler atmosphere above. Because, on average, the outgoing infrared radiation balances the incoming solar radiation, both the atmosphere and the surface will be warmer than they would be without the greenhouse gases. One should distinguish between the "natural" and a possible "enhanced" greenhouse effect. The natural greenhouse effect causes the mean temperature of the Earths surface to be about 33 degrees C warmer than it would be if natural greenhouse gases were not present. ...
The title here should strike a familiar theme for most readers. Climate forcings do not just include CO2 (other greenhouse gases, aerosols, land use, the sun, the orbit and volcanoes all contribute), and the impact of human emissions often has non-climatic effects on biology and ecosystems. First up last week was a call from Michael Prather and colleagues that the production of a previously neglected greenhouse gas (NF3) was increasing and could become a significant radiative forcing. This paper was basically an update of calculations done for the IPCC combined with new information about the production of this non-Kyoto gas.. Most of the media stories that picked this up focused on the use of this gas in a particular manufacturing process - flat screen TVs. Thus the headlines almost all read something like "Flat-screen TVs cause global warming"! (see here, here, here etc.). Unfortunately, very few of the headline writers read the small print.. NF3 is indeed a more powerful greenhouse gas than ...
We see a dip in the emission curve in a band around 15 mu m emitted at a temperature 220 K from a height of a bit less than 20 km, while outside the band the radiation is emitted from the Earth surface at about 270 K. The dip comes from the "greenhouse gases" (mainly water vapour and some CO2) which absorb radiation from the Earth surface emitted at 270 say and and re-emitting less radiation at 220 K and thus acting as a "warming blanket" causing the "radiative forcing" of the "greenhouse effect". The idea is that the "greenhouse effect" corresponds to the area of the dip shows the "greenhouse effect" as a combined effect of water vapor and ...
Scientists who research thermal radiation in the Earths atmosphere are confident that we have a very detailed and accurate understanding of the nature of the greenhouse effect of carbon dioxide (CO2), including the impact of rising CO2 levels. Recently I participated in a study that provided the first direct observation at the surface of the Earths increased greenhouse effect due to rising CO2 levels. This represents an important milestone in the detection of the increased greenhouse effect due to fossil fuel emissions.. ...
BACKGROUND OF THE INVENTION This invention relates to a method for the reduction of global warming resulting from the greenhouse effect, and in particular to a method which involves the seeding of the earths stratosphere with Welsbach-like materials. Global warming has been a great concern of many environmental scientists. Scientists believe that the greenhouse effect is responsible for global warming. Greatly increased amounts of heat-trapping gases have been generated since the Industrial Revolution. These gases, such as CO.sub.2, CFC, and methane, accumulate in the atmosphere and allow sunlight to stream in freely but block heat from escaping (greenhouse effect). These gases are relatively transparent to sunshine but absorb strongly the long-wavelength infrared radiation released by the earth. Most current approaches to reduce global warming are to restrict the release of various greenhouse gases, such as CO.sub.2, CFC, and methane. These imply the need to establish new regulations and the ...
A natural system known as the greenhouse effect regulates the temperature on Earth. Human activities have the potential to disrupt the balance of this system by increasing the amount of heat-trapping gases in the atmosphere which enhances the warming capability of the natural greenhouse effect. It is the human-induced enhanced greenhouse effect that causes environmental concern. It has the potential to warm the planet at a rate that has never been experienced in human history ...
Nevertheless, we can provide some information on the time-scale for detection by using the unprecedented change concept mentioned briefly in Section 8.14. This should provide an upper bound to the time of detection since more sophisticated methods should produce earlier results. We take a conservative view as a starting point namely that the magnitude of natural variability is such that all of the warming of the past century could be attributed to this cause. (Note that this is not the same as denying the existence of an enhanced greenhouse effect. With such a noise level the past warming could be explained as a 1°C greenhouse effect offset by 0.5°C natural variability.) We then assume, again somewhat arbitrarily that a further 0.5°C warming (i.e., a total warming of 1°C since the late nineteenth century) is required before we could say with high confidence, that the only possible explanation would be that the enhanced greenhouse effect was as strong as predicted by climate models. Given the ...
Carbon dioxide, the famous and vital to life gas, is also an important greenhouse gas. Since the combustion of fuels leads to the production of carbon dioxide it had to be expected that since the industrial revolution the concentration of carbon dioxide in the atmosphere was to be rapidly increased.. When the consequences and the causes of the greenhouse effect were understood, serious efforts were made by the global community to reduce the greenhouse gases production and CO2 among them. The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, commits State Parties, also EU among them, to reduce the greenhouse gases by setting internationally binding emission reduction targets. The first commitment period started in 2008 and ended in 2012 and had as goal an average 5% reduction of carbon dioxide and other greenhouse gases, whereas during the second commitment period (2013-2020) the parties committed to reduce greenhouse gas emissions at ...
The EPA, politicians, news media and other opinion makers rely heavily on the assertions by the United Nations Intergovernmental Panel on Climate Change (IPCC) that increased CO2 emissions cause global warming. The United Nations established the IPCC not to investigate global warming but to find a human cause for global warming. IPCC rules require all assertions in its assessment reports to be based on published papers in refereed scientific journals. That procedure was flagrantly violated in its Fourth Assessment Report. That report listed the World Wildlife Fund as the source for sixteen of its assertions, including that Himalayan glaciers would disappear by 2035. The WWF is an environmental advocacy group with no refereed journal but a well-deserved reputation for exaggerated, unsupported claims. The IPCC Fourth Assessment Report also cited a Greenpeace report, a mountaineering magazine and a student paper as sources. Obviously, the IPCC would not be using these unscientific sources if it ...
The present study focused on the East Asia, especially China for the past few decades to investigate (1) relationship between the change in human activities such as economy and industry and the change in emissions of a anthropogenic gasses and aerosols, and (2) the influence of the emitted gases and aerosols on the climate change and air pollution.. The macroanalysis of economy was performed as planned. The economic development in the East Asian countries led by the industrialization brought increases in energy consumption and emissions of CO2, SO2 and others. However, SO2 emission has not increased so much as expected. The emission density of CO2 has not increased or has decreased due to an improvement of energy efficiency.. The emission inventory was developed according to the initial plan, which includes anthropogenic greenhouse gases, aerosols, and precursors of aerosols for the period, 1980-2003. Figure 1, for example, shows the changes in the amount of the emission of SO2, NOx, and Black ...

By the end of this century, natural methane (CH4) emissions from wetlands are projected to increase by up to 80%, compared with the beginning of the century, if no concrete actions are taken to reduce anthropogenic greenhouse gas emissions, a JRC led study finds.
Why? Because plant-based proteins take fewer resources-energy, water, fuel-to produce than animal-based proteins. Its no secret that conventional (factory farmed) dairy production is not easy on the environment. The global dairy sector contributes 4% to the total global anthropogenic greenhouse gas emissions.4 Whey is a byproduct of the dairy industry, which uses more water, energy and fuel to produce than plant-based proteins-while emitting more greenhouse gases.. Because Vega Sport Performance Protein is more than just a protein (hello performance ingredients!), has a very comparable amino acid profile to whey, is clean, plant-based and more sustainable to whey, why not give it a try?

Carbon geosequestration (CGS) has been identified as a key technology to reduce anthropogenic greenhouse gas emissions and thus significantly mitigate climate change. In CGS, CO2 is captured from large point-source emitters (e.g., coal fired power stations), purified, and injected deep underground into geological formations for disposal. However, the CO2 has a lower density than the resident formation brine and thus migrates upward due to buoyancy forces. To prevent the CO2 from leaking back to the surface, four trapping mechanisms are used: (1) structural trapping (where a tight caprock acts as a seal barrier through which the CO2 cannot percolate), (2) residual trapping (where the CO2 plume is split into many micrometer-sized bubbles, which are immobilized by capillary forces in the pore network of the rock), (3) dissolution trapping (where CO2 dissolves in the formation brine and sinks deep into the reservoir due to a slight increase in brine density), and (4) mineral trapping (where the CO2 ...
With the defeat of the Democrats climate legislation in the filibuster-ruled Senate this year, that would have capped pollutants and reduced them annually, President Obama is today transferring to the EPA the regulation of greenhouse gases from refineries and coal plants that emit more than 25,000 tons of greenhouse gases, as promised.. In a statement today noting that these sources collectively contribute up to 40% of US greenhouse gas pollution, EPA chief Lisa Jackson said, "We are following through on our commitment to proceed in a measured and careful way to reduce greenhouse gas pollution that threatens the health and welfare of Americans and contributes to climate change.". The US Environmental Protection Agency is issuing the final series of actions that will ensure that the largest industrial facilities must have annually declining Clean Air Act permits that cover greenhouse gas emissions beginning in January 2011. These actions are part of EPAs common sense approach to permitting ...
Incidentally, we have a convenient phenomenon that contributes to our survival. Doubling the amount of CO2 in our atmosphere will not double the temperature rise, small though it is. The basic principle of whats known as the "greenhouse effect" is quite simple: in a glass-enclosed environment, sunlight enters through the glass and strikes a surface, where it is transformed into longer infrared rays which do not easily reflect back through the glass; theyre trapped. and raise the temperature. However, the greenhouse effect as applied to our planet is more complicated. The infrared rays that are reflected back from the Earth are trapped by the greenhouse gases, water vapor and CO2 -- a process that warms those gases and heats the Earth. This effect makes Earth habitable, preventing extremes of temperature. The limit of the influence of CO2 is dictated, not by the amount of greenhouse gases in the atmosphere, but by the amount of solar radiation reflected back from the Earth. Once all the ...
1] The impact of extreme sea ice initial conditions on modelled climate is analysed for a fully coupled atmosphere ocean sea ice general circulation model, the Hadley Centre climate model HadCM3. A control run is chosen as reference experiment with greenhouse gas concentration fixed at preindustrial conditions. Sensitivity experiments show an almost complete recovery from total removal or strong increase of sea ice after four years. Thus, uncertainties in initial sea ice conditions seem to be unimportant for climate modelling on decadal or longer time scales. When the initial conditions of the ocean mixed layer were adjusted to ice- free conditions, a few substantial differences remained for more than 15 model years. But these differences are clearly smaller than the uncertainty of the HadCM3 run and all the other 19 IPCC fourth assessment report climate model preindustrial runs. It is an important task to improve climate models in simulating the past sea ice variability to enable them to make ...
The Earth Institute at Columbia University, by Andrea Thompson and Ker Than. Our planet and its inhabitants - including we humans - are in a precarious position as we celebrate Earth Day, April 22.. While global warming is widely accepted as a reality by scientists and many governments and industrial leaders, progress to curb greenhouse gases and other forms of pollution remains limited. The current economic climate will likely make pollution control efforts more difficult, analysts say.. Recent studies, as well as the 2007 report by the Intergovernmental Panel on Climate Change (IPCC) have pointed to some of the likely effects of uncurbed greenhouse gas emissions: rising global temperatures, rising sea levels, Arctic sea ice melt, the disappear of glaciers, epic floods in some areas and intense drought in others.. These effects are intensified when combined with other forms of pollution the worlds rising population.. Humans will face widespread water shortages. Famine and disease will ...
Researchers in Japan have engineered a membrane with advanced features capable of removing harmful greenhouse gases from the atmosphere. Their findings, published in the British journal Nature Communications, may one day contribute to lower greenhouse gas emissions and cleaner skies.. Greenhouse gases, originating from industrial processes and the burning of fossil fuels, blanket the earth and are the culprits behind current global warming woes. The most abundant among them is carbon dioxide, which made up 84% of the United States greenhouse gases in 2012, and can linger in Earths atmosphere for up to thousands of years.. Countries all over the world are looking to reduce their carbon dioxide footprint. However, carbon dioxide is essentially a waste product with little immediate commercial value and large treatment costs. Therefore, new low-cost technologies are sorely needed to incentivize greenhouse gas capture by industry.. Easan Sivaniah - an associate professor at Kyoto Universitys ...
The effect of ventilation rate (VR) on ammonia and greenhouse gas emissions from co-composting dead hens mixed with hen manure was quantified. Three VR levels of 0.9, 0.7, and 0.5 m3 h-1 were evaluated. Gaseous concentrations were measured using a multi-gas infrared photoacoustic analyzer, VR was measured with flowmeters, and the gas emission rate was computed from the VR and gas concentration. Decomposition of the carcasses over the 11-week composting period was greater than 88%. VR was found to significantly affect NH3, CO2, and CH4 emissions (p | 0.05). Specifically, cumulative emissions per kg of initial matter for VR of 0.9, 0.7, and 0.5 m3 h-1 were, respectively, 2.4, 2.0, and 1.2 g NH3; 78, 66, and 42 g CO2; 120, 90, and 52 mg CH4; and 6.4, 6.1, and 5.1 mg N2O. Hence, the study results suggest that the ventilation rate can be adjusted to reduce NH3 and GHG emissions from animal mortality compositing.
The contribution of agriculture to New Zealands total greenhouse gas emissions is significant - over 50%, compared to the global average of 14%. In 2004 livestock contributed 90% of methane emissions and over 95% of nitrous oxide. Since 1990 New Zealands agricultural emissions have grown by about 1% each year.. As agriculture changed from sheep-dominated to mixed farming - with intensive dairy farming increasing since the 1980s - its role in New Zealands greenhouse gas emissions has become significant. In 2004, carbon dioxide comprised nearly half of New Zealands total greenhouse gas emissions, but subtracting the carbon dioxide removed from the atmosphere through activities such as forestry, reduces it to a net 19%. The major net contributors were methane (54%), and nitrous oxide (26%). Nitrous oxide emissions have grown with the increasing use of nitrogen fertilisers in farming.. Methane, a by-product of animal rumination (released in sheep and cow burps), is still of concern, with outputs ...
Much of the media discussion about last weeks Fifth Assessment Report of the Intergovernmental Panel on Climate Change centred on the slowdown in the rate of rise of Global Mean Temperature. This was held up by sceptics as evidence that climate models were unreliable. While preparing for a forthcoming conference, I re-plotted the data for…
The average surface temperature of Mars could be raised by producing greenhouse gases (chloro-fluoro-carbons, or CFCs) out of minerals available in the regolith (dirt). If sufficient CFCs were released to raise average surface temperature by 25 C (45 F), carbon dioxide frozen in the polar caps and regolith would thaw to a gas and enter the atmosphere triggering a runaway greenhouse effect. As carbon dioxide entered the atmosphere, pressure would rise and more of the sun s heat would be captured, thawing even more of the gas. Current estimates suggest enough carbon dioxide may be present to increase atmospheric pressure to 2,000 mbar, and raise average surface temperature above freezing. Should this happen, water vapor would make a significant contribution to the greenhouse effect and establish an active hydrological cycle ...

Carbon in the Earths atmosphere exists in two main forms: carbon dioxide and methane. Both of these gases absorb and retain heat in the atmosphere and are partially responsible for the greenhouse effect.[3] Methane produces a larger greenhouse effect per volume as compared to carbon dioxide, but it exists in much lower concentrations and is more short-lived than carbon dioxide, making carbon dioxide the more important greenhouse gas of the two.[8]. Carbon dioxide is removed from the atmosphere primarily through photosynthesis and enters the terrestrial and oceanic biospheres. Carbon dioxide also dissolves directly from the atmosphere into bodies of water (ocean, lakes, etc.), as well as dissolving in precipitation as raindrops fall through the atmosphere. When dissolved in water, carbon dioxide reacts with water molecules and forms carbonic acid, which contributes to ocean acidity. It can then be absorbed by rocks through weathering. It also can acidify other surfaces it touches or be washed ...

QuickLink: Greenhouse gas emissions from freshwater higher than thought -- ScienceDaily - The worlds rivers and streams pump about 10 times more methane into our atmosphere than scientists estimated in previous studies, new research shows. Like carbon dioxide, methane is a greenhouse gas that traps heat at Earths surface. It is less prevalent than carbon dioxide in the atmosphere but also more potent: A molecule of methane results in more warming than a molecule of carbon dioxide.
Reducing greenhouse gas emissions is an essential aspect of responsible resource development. Canada currently emits more than 700 megatonnes of greenhouse gasses (CO2, CH4 and N2O) per year and has made a bold commitment of reducing emission to 524 megatonnes per year.. Our national energy challenge to dramatically reduce GHG emissions while meeting ever-increasing energy demands.. University of Alberta researchers in the field of carbon capture, usage and storage (CCUS), are exploring ways to store CO2 safely, investigating how CO2 can be used as a tool for unconventional oil recovery, and converting CO2 into valuable chemical precursors.. One option being explored is converting CO2 into more valuable products, helping in economic diversification Researchers at the U of A are developing materials that purify CO2 using as little energy as possible-or convert it into carbon monoxide to produce high-value chemicals.. Another major research area is enhanced oil recovery, where refined CO2 is used ...

Greenhouse gases are gases that retain heat in the atmosphere. This created something called the greenhouse effect. It is normal function of our Earth. There are naturally occurring greenhouse emissions into the atmosphere like carbon dioxide. This happens through normal and natural processes and human activities. You might be surprised to find out that there are more greenhouse gases than all that carbon dioxide stuff youve been hearing about. There are some greenhouse gases that are only emitted by human activities such as fluorinated gases.. Greenhouse gases that release into the atmosphere due to human induced exploits include:. Carbon Dioxide (CO2): The most well known of the greenhouse gases, youve typically heard about carbon dioxide from a Greenpeace advocate, the weatherman, or on from some liberal news anchor. Whatever your thoughts are on climate change, science clearly tells us that carbon dioxide goes into our atmosphere from the process of burning fossil fuels. The main fossil ...
Estimates of uncertainties are essential when comparing the greenhouse gas (GHG) emissions from a variety of sources. Monte Carlo Simulation (MCS) was applied to estimate the uncertainties in methane emissions and the methane emission intensities from livestock in Canada, calculated using the Intergovernmental Panel on Climate Change (IPCC) methodology. National methane emissions from enteric fermentation and manure management in 2008 were 21·2 and 4·3 Teragram CO2 equivalents (Tg CO2e) with uncertainties of 38 and 73%, respectively. The methane emission intensities (kg of CO2e per kg of live animal weight) were 5·9, 0·9 and 4·9 from Canadian beef, swine and lamb, respectively, with overall uncertainties of 44, 99 and 101%, defined as the 95% confidence interval relative to the mean. A sensitivity analysis demonstrated that IPCC default parameters such as the methane conversion rate (Y m), the coefficient for calculating net energy for maintenance (Cf i ) and the methane conversion factor ...
Tom Dueck, of Wageningen University in the Netherlands, says his teams independent investigations are the first published results to show that plants methane emissions are negligible or zero.

The latest Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report stressed the need for the comprehensive and innovative evaluation of climate models with newly available global observations. The traditional approach to climate model evaluation, which is the comparison of a single parameter at a time, identifies symptomatic model biases and errors but fails to diagnose the model problems. The model diagnosis process requires physics-based multi-variable comparisons, which typically involve large-volume and heterogeneous datasets, and computationally demanding and data-intensive operations. We propose to develop a computationally efficient information system to enable the physics-based multi-variable model performance evaluations and diagnoses through the comprehensive and synergistic use of multiple observational data, reanalysis data, and model outputs. Satellite observations have been widely used in model-data inter-comparisons and model evaluation studies. These studies ...
Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus.
Melbourne: Monday 8 October, 2018: Latest Intergovernmental Panel on Climate Change (IPCC) findings released today are further confirmation that carbon capture and storage (CCS) is essential to mitigating climate change.. Welcoming the release of the IPCCs Special Report of 1.5 Degrees, the world authority on CCS, the Global CCS Institute, said 2 degrees, let alone 1.5 degrees, cannot be met without CCS and the best climate science available was continuing to support that fact.. Global CCS Institute CEO, Brad Page, said as the world veered off-track in meeting international climate change commitments, it was pressingly apparent that CCS was an essential part of the arsenal of clean technologies needed to combat climate change.. "The IPCCs report reconfirms the role which carbon capture and technology must play in beating climate change, and the fact that all technologies are necessary.. "As the IPCC has acknowledged, the extreme weather events witnessed around the world over the past few ...
Greenhouse gases such as carbon dioxide, carbon monoxide, and methane trap heat in Earths atmosphere through the greenhouse effect. Many human activities add greenhouse gases to the atmosphere, particularly the burning of fossil fuels. The more of these gases exist in the atmosphere, the more heat is trapped. This contributes to global warming ...
According to the preliminary estimate that must be submitted to the European Commission on 15 January, greenhouse gas emissions in Finland amounted to 78.5 Mt of CO2 equivalent in 2007, which is approximately two per cent less than in 2006. Emissions in 2007 exceeded by good 10 per cent the target level of the 2008-2012 commitment period under the Kyoto Protocol. In the past five reporting years emissions in Finland have exceeded by an average of nearly 7.5 million tonnes, or ten per cent, the amount assigned for them in the Kyoto Protocol (71 million tonnes). Annual fluctuations in the emissions have been large. These have arisen especially from variations in the availability of hydro power on the Nordic electricity market, imports of electricity from Russia and the annual structure and volume of domestic energy production ...
The new IPCC Report (2007) states, on page 10, "Most observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations."

Vegetation growth at Earths northern latitudes increasingly resembles lusher latitudes to the south, according to a NASA-funded study based on a 30-year record of land surface and newly improved satellite data sets. An international team of university and NASA scientists examined the relationship between changes in surface temperature and vegetation growth from 45 degrees north latitude to the Arctic Ocean. Results show temperature and vegetation growth at northern latitudes now resemble those found 4 degrees to 6 degrees of latitude farther south as recently as 1982. "Higher northern latitudes are getting warmer, Arctic sea ice and the duration of snow cover are diminishing, the growing season is getting longer and plants are growing more," said Ranga Myneni of Boston Universitys Department of Earth and Environment. "In the norths Arctic and boreal areas, the characteristics of the seasons are changing, leading to great disruptions for plants and related ecosystems." The study was published ...
Try and picture a very thin layer of gases - a quarter-inch, half an inch, somewhere in that vicinity - thats how thick it is. Its in our atmosphere. Its way up there at the edge of the atmosphere. And for millions of years - literally millions of years - we know that layer has acted like a thermal blanket for the planet - trapping the suns heat and warming the surface of the Earth to the ideal, life-sustaining temperature. Average temperature of the Earth has been about 57 degrees Fahrenheit, which keeps life going. Life itself on Earth exists because of the so-called greenhouse effect. But in modern times, as human beings have emitted gases into the air that come from all the things we do, that blanket has grown thicker and it traps more and more heat beneath it, raising the temperature of the planet. Its called the greenhouse effect because it works exactly like a greenhouse in which you grow a lot of the fruit that you eat here. ...

A guest post by Spencer Weart, in collaboration with Raymond T. Pierrehumbert The simple physics explanations for the greenhouse effect that you find on the internet are often quite wrong. These well-meaning errors can promote confusion about whether humanity is truly causing global warming by adding carbon dioxide to the atmosphere. Some people have been arguing that simple physics shows there is already so much CO2 in the air that its effect on infrared radiation is saturated meaning that adding more gas can make scarcely any difference in how much radiation gets through the atmosphere, since all the radiation is already blocked. And besides, isnt water vapor already blocking all the infrared rays that CO2 ever would?. The arguments do sound good, so good that in fact they helped to suppress research on the greenhouse effect for half a century. In 1900, shortly after Svante Arrhenius published his pathbreaking argument that our use of fossil fuels will eventually warm the planet, another ...
In the greenhouse business the radiative heat transfer acts as a heat pump counteracted by convection. Conduction would also counteract the greenhouse effect if it hadnt been neglected. But if heat radiation is essentially like heat conduction then the heat radiation would counteract the greenhouse effect, which is based on heat radiation and there we have the problem in a nutshell. The discussion about photons/waves is interesting in its own right but not really relevant here ...
The effect caused by some atmospheric gases trapping heat close to a planets surface. This makes the surface and lower atmosphere of the Earth warmer than they would be if direct heating from the Sun was the only warming mechanism; without it, the average surface temperature on Earth would only be around -19°C.. ...
Besides carbon dioxide, methane is the most important anthropogenic greenhouse gas in the atmosphere. Global atmospheric CH4 concentration increased by more than a factor of two since the beginning of industrialisation. Although the atmospheric CH4 abundance is still very small compared to that of CO2 the additional radiative forcing of additional CH4 since 1750 is about 1/3 of that of the CO2 increase. Methane has both, natural and anthropogenic sources and is mainly produced by bacteria in anaerobic environments that have high organic matter content. Such bacterial sources are natural wetlands, rice agriculture, animal breeding (ruminants), landfills, termites as well as aquatic sediments. Other so called thermogenic sources are incomplete combustion of biomass and energy generation where methane is released by extraction, processing and distribution of coal, gas and oil. About 40% of total CH4 emissions come from natural, 60% from anthropogenic sources. The main sink of methane is chemical ...
The newly published synthesis of the Fifth Assessment Report from the Intergovernmental Panel on Climate Change (IPCC) is yet another reminder that to maintain a legitimate shot at avoiding warming of greater than 2 °C, greenhouse-gas emissions must be cut 40 to 70 percent by midcentury and reduced to zero by 2100. How exactly to…
Despite a sustained production of anthropogenic greenhouse gases, the Earths mean near-surface temperature paused its rise during the 2000-2010 period1. To explain such a pause, an increase in ocean heat uptake below the superficial ocean layer2, 3 has been proposed to overcompensate for the Earths heat storage. Contributions have also been suggested from the deep prolonged solar minimum4, the stratospheric water vapour5, the stratospheric6 and tropospheric aerosols7. However, a robust attribution of this warming slowdown has not been achievable up to now. Here we show successful retrospective predictions of this warming slowdown up to 5 years ahead, the analysis of which allows us to attribute the onset of this slowdown to an increase in ocean heat uptake. Sensitivity experiments accounting only for the external radiative forcings do not reproduce the slowdown. The top-of-atmosphere net energy input remained in the [0.5-1] W m−2 interval during the past decade, which is successfully ...
The atmosphere itself contains plenty of puzzles. Hakan Svedhem, project scientist for Venus Express, says, "The atmosphere of Venus is unique in the Solar System, so understanding it is very important." What we know about our own atmosphere does not much help us understand Venus. How can Earth s twin possess such a different atmosphere? The thick atmosphere creates a greenhouse effect, making Venus hotter than a kitchen oven. This greenhouse effect is definitely worth studying. Another mystery concerns the movement of the atmosphere. About 60 kilometres above the surface, winds race through the cloud cover at almost 400 kilometres per hour. They make the atmosphere rotate, but we do not know how this so-called super-rotation occurs ...
The incoming energy from the Sun to Earth is mainly visible sunlight, called the visible portion of the spectrum of electromagnetic radiation. We perceive visible sunlight as colors from violet (short-wave radiation) to red (long-wave radiation). The sequence of colors seen in the rainbow represents the spectrum of this light, ordered according to wavelength. A relatively minor amount of energy leaves the sun as radiation with shorter wavelength ( ultraviolet ) and as radiation with longer wavelength ( infrared or heat radiation ). Visible light (the colors of the rainbow) occupies the narrow part of the spectrum between the dashed lines in the first figure. The (invisible) light with wavelengths just shorter than violet is called ultraviolet, meaning beyond violet. It is largely absorbed in the atmosphere and only a modest amount of this light arrives at the surface of Earth. This is fortunate, because ultraviolet light, abbreviated UV, can cause damage to skin and to vertebrate retinas and ...
Dear Sir, you should be using the adiabatic formulae? Your derived pressure lapse rate is for constant temperature. The principle is sound, however the adiabatic formula cannot have T = 255 at the centre of mass of the column of atmosphere. Although, I understand you have used the average temperature in the isometric formula. I am convinced that the +33C is due to gravitational redistribution of kinetic energies of molecules. I am still working on the problem in my own time. Observations from radiosondes actually give a better fit to pressure with height using the isometric equation you describe, than with the adiabatic formula, this is a bit confusing for me and I am still working on it. The radiosonde data I have looked at shows the average temperature (weighted by mass of course) of the atmospheric column is equal to the OLR measured by satellite - within a couple of percent. I got the OLR data from KNMI. I am looking for a more rigorous demonstration - i.e. resisting the urge to use the ...
If the CO2 effect was saturated, adding more CO2 should add no additional greenhouse effect. However, satellite and surface measurements observe an enhanced greenhouse effect at the wavelengths that CO2 absorb energy. This is empirical proof that the CO2 effect is not saturated.

Despite 20 years of effort, greenhouse gas emissions are going up instead of down, hitting record highs as climate negotiators gather to debate a new global warming accord.
Brazils greenhouse gas emissions (GHG) fell 4.9 percent in 2012 as declining deforestation rates and a drought-induced drop in cattle herds outweighed increased emissions from the energy sector, an independent study showed on Thursday.
Under the EPA's greenhouse gas reporting rule, suppliers of fossil fuels or industrial greenhouse gases, manufacturers of vehicles and engines, and facilities that emit 25,000 metric tons or more per year of GHG emissions are required to submit annual reports to EPA beginning in 2011.
The California Global Warming Solutions Act (AB 32) set a target of reducing greenhouse gas emissions to 1990 levels by 2020, which equals about 431 million metric tons. Last year, the Governor and the Legislature established a 2030 target of an additional reduction of 40 percent below 1990 emission levels - the most ambitious goal in North America. The new data shows that California is on its way to meet these targets. Since the peak of 489 MMT in 2004, statewide emissions have declined by 10 percent, with the latest inventory showing emissions of 440 MMT in 2015. ...

However, it also said that "major investments" will be needed in nuclear new build, lifetime extension and safety upgrades, fuel cycle operations, decommissioning and waste management. [Native Advertisement] The group said nuclear power contributes to Europes three energy policy goals: security of supply, electricity sector decarbonization and competitive power prices. And it noted that the Intergovernmental Panel on Climate Change has said nuclear is "an effective greenhouse gas mitigation option".. In the paper, Foratom called on the Commission to "apply a technology-neutral approach" in its Guidelines on State Aid for Environmental Protection and Energy, in order to "facilitate investment in all low-carbon technologies including nuclear, and provide a stable regulatory and investment framework".. "Given that new nuclear projects are capital intensive and take a long time to begin generating income," Foratom said, "developers should be given assurances that the EC and the relevant Member ...
My research interests are in the spatial modelling of land use change, grassland and forest management, processes affecting greenhouse gas emissions from land management and interdisciplinary approaches to investigating human-environmental impacts. I am the lead scientist for the Department of Energy and Climate Change (DECC) funded project that produces annual estimates of sources and sinks of greenhouse gases in the land use, land use change and forestry (LULUCF) sector of the national greenhouse gas inventory. This inventory is required under national and international commitments (the UK Climate Change Act and the Kyoto Protocol of the UN Framework Convention on Climate Change). My current work focuses on extending reporting on forest, peatland and agricultural land management through the development of computer models.. For recent publications on this work please see http://naei.beis.gov.uk/reports/reports?section_id=3 I am a scientific adviser to the UK government on sources and sinks of ...
Synapse was hired by the Public Interest Research Groups to review drafts of state greenhouse gas reduction reports. The reports explored the brief history and context of greenhouse gas reduction efforts in selected states and performed calculations to estimate emission reductions from a suite of policies. In January and February 2004, Synapse edited the text of the
Composting can be an effective means of biodegrading livestock mortalities in emergency disposal situations, such as disease outbreaks. Within the past decade, our knowledge detailing composting has increased substantially. However, research data linking the environmental impact of composting to atmospheric and terrestrial systems are limited. We investigated composting efficacy, greenhouse gas emissions, and leachate properties from two static compost piles, each containing 16 cattle mortalities, built with either beef manure (BM) or wood shavings (WS) as envelope material. Wood shavings achieved a greater maximum temperature than BM (60 vs. 50°C) and maintained higher temperatures over 200 d (p , 0.001). Greenhouse gas emissions were evaluated using a static chamber and gas chromatography. Emissions of N2O (p , 0.001), CH4 (p , 0.01), and CO2 (p , 0.05) were lower from WS than BM, resulting in 3-fold lower total CO2 equivalent emissions. After 250 d of composting, piles were relocated, and ...
The Palestinian Authority has been approved to join the climate cluckers on the United Nations Framework Convention on Climate Change. As such, U.S. law dictates that domestic funding toward enforcing this treaty, via global reductions of greenhouse gases, must be eliminated.. U.S. Code Title 22, Section 287e, is clear, as the Heritage Foundation reports: "No funds … shall be available for the United Nations or any specialized agency thereof which accords the Palestinian Liberation Organization the same standing as member states.". And the law has precedent - namely, the elimination of U.S. funding for the United Nations Educational, Scientific and Cultural Organization in 2011 when Palestinians join it.. The U.N. climate change framework is supposed to curb greenhouse gas emissions that contribute to global warming. It was the foundation for the previous Kyoto Protocol and now the equally dubious Paris agreement.. And climate change being Job One for President Obama, he has requested $13 ...

Sir, The allegation that "burning wood for power can increase greenhouse gas emissions" (letter, May 2) is false. There is only a fixed amount of carbon in wood which is released as CO2 whether it rots in the forest or is combusted for energy in a boiler. If wood is converted into composites which are subsequently landfilled after use, greenhouse gases are produced. The major one is methane which is 64 times more powerful than CO2, in greenhouse effect terms. Professor Andrew Porteous ...
The 21st session of the Conference of the Parties (COP21) of the United Nations Framework Convention on Climate Change (UNFCCC) was held in Paris in November and December 2015. 195 participating countries negotiated and adopted the Paris Agreement, which includes objectives to peak greenhouse gas emissions as soon as possible, to limit the global average temperature increase above pre-industrial levels to well below 2°C, and to pursue efforts to limit the increase to 1.5°C.. The Paris Agreement, which entered into force on 4 November 2016, requires Parties to put forward their best efforts through "nationally determined contributions" (NDCs). These NDCs represent targets and actions for the post-2020 period. Per its NDC, Thailand intends to reduce its greenhouse gas emissions by 20 percent from the projected business-as-usual (BAU) level by 2030 (unconditional). The level of contribution could increase up to 25 percent, subject to adequate and enhanced access to technology development and ...
As shown in the diagram when infra red rays come from the sun come rays could be reflected back into space (50%), turned from UV into Infra Red rays on the surface (available as heat) or trapped in our atmosphere by green house gases. What greenhouse gases does is when infra red rays get reflected back out the space the infra red rays could hit greenhouse gases, it will absorb the energy and re-emitt the infra red but also re-distributes the energy back into the surface which increases the surface temperature. Enhanced greenhouse effects refers to the thickening of the greenhouse gas layer through pollutants such as carbon dioxide, methane which will absorb more infra red which will raise the temperature and can lead to climate change.CFCs deplete the ozone layer (O3) into O2, O3 is good at absorbing UV light and depleting it means more UV light will get to the surface. [CCl2F=sunlight,CCLF+CL-] Sources of CFCs are aerosols, air conditioner, refrigeration etc ...
3) Specifically, Congress may wish to consider the follwing lessons from the CDM: (1) that it may be possible to achieve the CDMs sustainable development goals and emissions cuts in developing countries more directly and cost-effectively through a means other than the existing mechanism; (2) that the use of carbon offsets in a cap-and-trade system can undermine the systems integrity, given that it is not possible to ensure that every credit represents a real, measurable, and long-term reduction in emissions; and (3) that while proposed reforms may significantly improve the CDMs effectiveness, carbon offsets involve fundamental tradeoffs and may not be a reliable long-term approach to climate change mitigation ...
The first protocol to the UN Framework Convention on Climate Change (UNFCCC) was adopted in Kyoto in 1997. It is a unique international law instrument which sets stringent, legally binding targets for the reduction of emissions of the greenhouse gases. Drawing on the emerging body of expertise in this complex area, this book conveys a knowledge of what is becoming known as Carbon Finance.
Burney, a postdoctoral researcher with the Program on Food Security and the Environment at Stanford, said agriculture currently accounts for about 12 percent of human-caused greenhouse gas emissions. Although greenhouse gas emissions from the production and use of fertilizer have increased with agricultural intensification, those emissions are far outstripped by the emissions that would have been generated in converting additional forest and grassland to farmland.. "Every time forest or shrub land is cleared for farming, the carbon that was tied up in the biomass is released and rapidly makes its way into the atmosphere - usually by being burned," she said. "Yield intensification has lessened the pressure to clear land and reduced emissions by up to 13 billion tons of carbon dioxide a year.". "When we look at the costs of the research and development that went into these improvements, we find that funding agricultural research ranks among the cheapest ways to prevent greenhouse gas emissions," ...

While natural water vapor has the greatest impact on the greenhouse effect, carbon dioxide, methane, and nitrous oxide are the most notable man-made contributors.
Downloadable! As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant processes of a product, has become the accepted procedure to use to determine greenhouse gas emissions of products ranging from transportation fuels, to building materials, to food production (Farrell et al., 2006; Hill et al., 2006; Owen, 2004). The basic motivation of LCA is that, to conduct a fair assessment of the environmental impacts of a product, it is necessary to take into account all of the processes throughout the products lifespan, including the extraction of raw material, the manufacturing processes that convert raw material into the product, and the utilization and disposal of the product. For many products, including fossil fuels, a standard LCA is generally all that is needed to
The Kyoto Protocol signed in 1997 caps the emissions of greenhouse gas including carbon dioxide. The move makes carbon emission rights become scarce, thus the global carbon market and trading of carbon emission allowance and credits taking shape. Under the arrangement of the framework of Kyoto Protocol during the past ten years, carbon trading scheme has gradually become the one of the preferred political instrument by many countries to address climate change issues.

April 19, 2011. Greenhouse gas emissions in the US dropped to their lowest level in 15 years in 2009 as the impact of the financial crisis led to decreases in fuel and electricity consumption, according to newly published figures.. In 2009, the US saw its emissions of the six main greenhouses gases drop 6 per cent year-on-year to 6,633m metric tonnes, the lowest total since 1995. Despite that annual fall, emissions rose by more than 7.3 per cent between 1990 and 2009.. The figures, released by the Environmental Protection Agency, are likely to be seized upon by Republicans as evidence that there is no need for further regulation of carbon emissions. The GOP has embarked on a campaign in recent months to strip the EPA of its ability to regulate hydrocarbons as well as other pollutants.. A Republican-sponsored bill recently passed by the House has been viewed as a wide-ranging attack on the EPA. The proposed legislation argues that carbon dioxide was not mentioned in the Clean Air Act which gave ...
Description: The European Unions (EUs) Emissions Trading System (ETS) is a cornerstone of the EUs efforts to meet its obligation under the Kyoto Protocol. It covers more than 11,500 energy intensive facilities across the 25 EU member countries, including oil refineries, power plants over 20 megawatts (MW) in capacity, coke ovens, and iron and steel plants, along with cement, glass, lime, brick, ceramics, and pulp and paper installations. Covered entities emit about 45% of the EUs carbon dioxide emissions. The trading program does not cover emissions of non-CO2 greenhouse gases, which account for about 20% of the EUs total greenhouse gas emissions. A final consideration for the ETS is its suitability for directing long-term investment toward a low-carbon future - the ultimate goal of any climate change program. ...
