US and Swiss researchers have, for the first time, modelled a climate system with extremely high carbon emissions in an attempt to test the boundaries of the current computer simulation programs that inform us.. Published today, Tuesday 5 July, in IOP Publishings journal Environmental Research Letters, the study has revealed the potentially devastating effects that high carbon emissions could have on our climate.. Little attention has previously been paid to the upper bound range of future emissions which, as the researchers state, is imperative when testing the outcomes of climate change simulations.. The A1FI scenario, considered in the most recent report from the Intergovernmental Panel on Climate Change (IPCC), represents the upper bound of predicted carbon emissions.. The researchers, from the National Centre for Atmospheric Research, Colorado, and the Institute for Atmospheric and Climate Science, Zurich, created two hypothetical high carbon emission scenarios and compared their effects ...

Ocean and coastal law has grown rapidly in the past three decades as a specialty area within natural resources law and environmental law. The protection of oceans has received increased attention in the past decade because of sea-level rise, ocean acidification, the global overfishing crisis, widespread depletion of marine biodiversity such as marine mammals and coral reefs, and marine pollution.

In 16. I asked: Are the authors suggesting that the enhancement in global temperature by about 5 Deg C near the time of the Paleocene Eocene Thermal Maximum (PETM) 55 million years ago (mya) may have been largely due to a global transformation in vegetation from one associated mainly with a temperate climate to one associated mainly with a tropical and subtropical global climate? In his Response to my question gavin replied: Not possible. The amounts of carbon released at the PETM are roughly 3 times the total amount of terrestrial biomass - it therefore needed a completely different source of carbon. - gavin]. However, my question in 16. pertained to an enhancement in global temperature (by about 5 Deg C), not the full extent of the rise in global temperature to the PETM.. From Zanchos(2005), … During the Paleocene-Eocene thermal maximum (PETM), sea surface temperatures (SST) rose by 5° C in the tropics and as much as 9° C at high latitudes (1-3), whereas bottom-waters temperatures ...

What we have regarding satellite derived temperatures are two different methods for presenting a global temperature average that attempts to represent the measurement of tropospheric heat conditions. That is a well accepted standard way of demonstrating observation robustness. Diurnal drift artifact is a mechanism well understood by many disciplines. It is a potential artifact in both types of satellite measurement methods being discussed here. One method to correct for it is partly derived from a climate model (dynamical or statistical version I do not know) used to adjust diurnal drift, the other method is partly derived from a physics-based mathematical mechanism calculation designed to accommodate the known physics of satellite diurnal drift. As to the effort made that resulted in the two methods showing close agreement, the two methods appear quite divorced from each other though I dont know the particulars. I do not have first hand knowledge if conversations occurred between the two camps ...

A number of people are concerned that Earths temperature will rise so high and so fast in response to CO2-induced global warming that many alpine plant and animal species will soon be mere memories, because of the assumption that after being forced to migrate to the tops of the mountains upon which they now reside at lower levels, there will be nowhere else for them to go in a vertical direction but to the sorry state of extinction.. ...

A warming climate could affect the stability of alpine grasslands in Asias Tibetan Plateau, threatening the ability of farmers and herders to maintain the animals that are key to their existence, and potentially upsetting the ecology of an area in which important regional river systems originate.

Temperatures may rise to a point where animal and plant life start dying in massive numbers, scientists say. The theory is hotly debated.

Howard Malloy, via BoatingWorld.com. I havent seen that problem in a marine engine, but had it happen in the only Chevy I ever owned when the end dropped off the radiator and there was no coolant to measure and, therefore, no warning via the temp sender. Id accept the mechanics theory, but why is the problem apparent for the second time? Did the engine fail again, or were you able to prevent it? I think lots of questions are in order: Was the replacement engine new or remanufactured, or was yours rebuilt? Do you have a closed or open cooling system? If closed, was the system checked for leaks? If a failed head gasket pumped air into the coolant, then there should be evidence of coolant in the oil, not to mention a poor-running engine and low compression on at least one cylinder. If the problem has occurred again, did the evidence from the first failure present itself in the same fashion or place the second time?. Unless it took several years for the problem to show the second time, there may ...

With what may be the warmest year in centuries about to close, I thought it would be fun to have a graphic comparing the march of global average temperature over several years about a century ago with the present state of affairs. This graphic is based on NASAs data, using John Abrahams estimate for the 2014 temperature (it might end up being a tiny bit different). There is more information about those sources here.

Re Gavins comments.. In respect to Dr Landseas resigination letter I suggest that you open a disscusion thread on it similar to the ones you have for Will, Crichton, Inhofe. Certianly it was equally important in the realm of climate science.. [Response: We considered commenting on Landsea. But there doesnt really seem to be a lot of science behind this, it doesnt seem to be terribly important in the realm of science, and none of us (I think) are very familiar with the hurricanes stuff: Im certainly not. I must correct your open a disscusion thread: please dont mistake RC for a newsgroup - William]. Regarding global mean temperatures I remain skeptical but I am hopeful you can satisfy my skepticism. I maintain that historic temperature records were never collected for the purpose that they are being put to (measuring global mean temperature). Theyre in the wrong places to do this and represent only highs and lows and not a fully integrated mean. I thus believe that to this day global mean ...

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 ...

Many studies have documented the gender imbalance in science and have explored the reasons that women are not included or represented, especially at more senior levels of research (8⇓⇓⇓⇓-13). A 2013 special report in the journal Nature concludes that, despite some improvements, female scientists continue to face discrimination, unequal pay, and funding disparities and notes that, internationally, 70% of men and women view science as a male pursuit (14). Women face barriers associated with their family responsibilities and are poorly represented in journals and citations (15⇓⇓-18). Including women in research teams enhances innovation and discovery (19⇓-21). Claims about data and explanations of womens underrepresentation in science can be controversial with some suggesting women choose to not pursue a career in science and others recognizing more structural causes (17, 22⇓-24). In our own discipline of geography, several studies have identified barriers facing women in physical ...

In 100 years, summers in Los Angeles may be as scorching as summers in the Mojave Desert. But it doesnt have to be that way, according to a team of 19 scientists that includes Norman Miller and Larry Dale of DOEs Lawrence Berkeley National Laboratory.. In a study published in the August 16th issue of the Proceedings of the National Academy of Sciences, the research team predicted that Californians could experience substantially hotter summers by the end of the century, which may lead to an increase in heat-related deaths and water and energy shortages. Just how hot depends on whats done between now and then. The researchers analyzed two greenhouse gas emission scenarios recently presented by the Intergovernmental Panel on Climate Change, a United Nations-formed organization that informs the worlds policymakers on climate change and impacts. One scenario assumes an energy-use trajectory similar to the present course, meaning rapid introduction of new technologies, extensive economic ...

Climate variability and change has been considered to be posing the greatest threat to agriculture and food security in many of the poor, agriculture - based countries in Africa. In recognition of t his, an assessment of climate change impacts on small - scale farmers was conducted in Nyandarua South District to assess the impacts of climate variability and change on the small - scale farmers in the area. The area is nationally known as a high agricultura l potential area producing all year round horticulture produce. Data was obtained through administration of questionnaires, observation and focused group discussions. Through systematic random sampling the researcher administered 375 households questionna ires representing 10% of the total households in the study area. Descriptive statistics (frequency, mean, percentages) and inferential statistics (chi square) were used to produce associations between variables assessed. The results indicate that small - sca le farmers in North Kinangop ...

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 ...

Sean Mickalitis News Editor. Earlier this month, the Intergovernmental Panel on Climate Change (I.P.C.C) released a report on global warming.. According to the report, the atmospheres average temperature will increase by 2.7 degrees Fahrenheit (1.5 degrees Celsius) by the year 2040, due to greenhouse gas emissions, resulting in famine, drought, mass-extinctions and many other catastrophic events.. Now is the time to save the planet and ourselves before we reach the event horizon.. According to NASA, the average global temperature has been steadily increasing since the industrial revolution.. Since 1880, Earths atmospheric temperature has climbed by 1.4 degrees Fahrenheit (0.8 degrees Celsius) with two-thirds of that increase happening after 1975.. Many people, myself included, blame negligent politicians and corporations for the current and impending destruction of the planet and our livelihoods, and, of course, they should be held accountable for they are our leaders, but what about the ...

On September 23 through 26, representatives of the worlds Environment Ministries will meet in Stockholm to agree on the final draft of a key portion of the latest Intergovernmental Panel on Climate Change (IPCC) Summary for Policymakers gospel which is expected, once again, to keep the political climate cauldron steaming. This Fifth Assessment Report (AR5) is intended to be used by international ministers working to devise a new global treaty by 2015 to curb climate change.. That goal is certainly no trifle, given that dramatic climate changes have been occurring over many millions of years, although lately…not so much. Therein lies the big rub. How can ministers conjure up a newsworthy sequel to previous knuckle-biting prognostications when all evidence suggests that the prophesies, and the scriptures they were based upon, were proven wrong?. ...

Description: The Intergovernmental Panel on Climate Change (IPCC) Special Report on Land Use, Land-Use Change, and Forestry (SR-LULUCF) has been prepared in response to a request from the United Nations Framework Convention on Climate Change (UNFCCC) Subsidiary Body for Scientific and Technological Advice (SBSTA). At its eighth session in Bonn, Germany, 2-12 Ju and technical implications of carbon sequestration strategies related to land use, land-use change, and forestry activities. The scope, structure, and outline of this Special Report was approved by the IPCC in plenary meetings during its Fourteenth Session. This Special Report examines several key questions relating to the exchange of carbon between the atmosphere and the terrestrial pool of aboveground biomass, below-ground biomass, and soils. Vegetation exchanges carbon dioxide between the atmosphere and the terrestrial biosphere through photosynthesis and plant and soil respiration. This natural exchange has been occurring for hundreds ...

He regularly interacts with policy makers in EPA, USDA and the Canadian government. This has contributed to changes in policy thinking on these issues.. ...

IPCC report targets methane. The landmark report by the UN Intergovernmental Panel on Climate Change calls on the global community to make strong, rapid and sustained reductions in methane emissions alongside CO2-related initiatives. Having 80 times the warming power of CO2 per unit of mass, methane nevertheless has a much shorter atmospheric lifetime of some 20 years, Oiprice said. An IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty. Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate. Reflecting the long-term warming trend since pre-industrial ...

For decades, estimates of the equilibrium climate sensitivity (ECS) to doubling of CO2 simulated by global climate models (GCMs) have had a large intermodel spread, with a 5th-95th percentile range of approximately 2-4.5 K [1,2]. Global cloud feedbacks are the largest contributor to this spread [2,3]. Fig. 7.10 from the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) [2] showed global cloud feedbacks diagnosed from over 20 GCMs participating in recent rounds of the Coupled Model Intercomparison Project (CMIP3 and CMIP5) and Cloud Feedbacks Model Intercomparison Project (CFMIP2). These have an interquartile range of 0.5-0.9 W m−2 K−1, and an overall intermodel spread of 0.2-1.4 W m−2 K−1, including the effects both of warming and of rapid adjustments to increased CO2. Given the CMIP3/5 multi-model mean Planck feedback (−3.2 W m−2 K−1), water vapour/lapse rate feedback (1.0 W m−2 K−1) and snow/ice albedo feedback (0.3 W m−2 K−1), together with ...

A report released by the UN Intergovernmental Panel on Climate Change (IPCC) has found that if the world continues to warm at its current rate, global temperatures will rise by 1.5°C between 2030 and 2052. This will have catastrophic effects on water scarcity, global food production, and almost entirely wipe out global coral reef systems.. For Africa and Sub-Saharan Africa in particular the findings of the report are especially damning. Without immediate global cuts in carbon dioxide emissions, average temperatures in Africa will rise more than two degrees celsius above pre-industrial levels by 2050. By this time, heat extremes never experienced before by humans in this part of the world could affect 15% of sub-Saharan Africas land area in the hot season, causing deaths and threatening farmers ability to grow crops.. The report is the result of the work of 91 dedicated lead authors and review editors from 40 countries, and the inputs of 133 contributing authors. This group assessed more than ...

Global Warming: An increase in the near surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases. Scientists generally agree that the Earths surface has warmed by about 1 degree Fahrenheit in the past 140 years. The Intergovernmental Panel on Climate Change (IPCC) recently concluded that increased concentrations of greenhouse gases are causing an increase in the Earths surface temperature and that increased concentrations of sulfate aerosols have led to relative cooling in some regions, generally over and downwind of heavily industrialized areas. (See: climate change). Global Warming Potential: The ratio of the warming caused by a substance to the warming caused by a similar mass of carbon dioxide. CFC-12, for example, has a GWP of 8,500, while water has a GWP of zero. (See: Class I Substance and Class II ...

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 ...

SOURCE: Cosmos Magazine. DATE: July 2, 2018. SNIP: Clouds are wispy evanescent things, beloved of poets and daydreamers. They may also determine whether civilisation as we know it survives the 21st century.. Depending on how clouds react to global warming, they could cool or cook the planet. But, so far, we havent been able to predict which way they will swing. Thats a big problem for our ability to prepare for whats coming.. At issue is climate sensitivity, which measures how much the temperature changes if the amount of carbon dioxide (CO2) in the atmosphere doubles. In 2014 the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) estimated this number somewhere between 1.5 and 4.5°C. This huge range comes down almost entirely to the effect of clouds.. By amplifying warming or reining it in, clouds could make the difference between a 2°C increase - where sea levels rise a metre or more and deadly heatwaves are predicted - and a truly catastrophic 4.5°C - which, ...
