A carbon cycle science update since IPCC AR-4. (7/172)

We review important advances in our understanding of the global carbon cycle since the publication of the IPCC AR4. We conclude that: the anthropogenic emissions of CO2 due to fossil fuel burning have increased up through 2008 at a rate near to the high end of the IPCC emission scenarios; there are contradictory analyses whether an increase in atmospheric fraction, that might indicate a declining sink strength of ocean and/or land, exists; methane emissions are increasing, possibly through enhanced natural emission from northern wetland, methane emissions from dry plants are negligible; old-growth forest take up more carbon than expected from ecological equilibrium reasoning; tropical forest also take up more carbon than previously thought, however, for the global budget to balance, this would imply a smaller uptake in the northern forest; the exchange fluxes between the atmosphere and ocean are increasingly better understood and bottom up and observation-based top down estimates are getting closer to each other; the North Atlantic and Southern ocean take up less CO2, but it is unclear whether this is part of the 'natural' decadal scale variability; large-scale fires and droughts, for instance in Amazonia, but also at Northern latitudes, have lead to significant decreases in carbon uptake on annual timescales; the extra uptake of CO2 stimulated by increased N-deposition is, from a greenhouse gas forcing perspective, counterbalanced by the related additional N2O emissions; the amount of carbon stored in permafrost areas appears much (two times) larger than previously thought; preservation of existing marine ecosystems could require a CO2 stabilization as low as 450 ppm; Dynamic Vegetation Models show a wide divergence for future carbon trajectories, uncertainty in the process description, lack of understanding of the CO2 fertilization effect and nitrogen-carbon interaction are major uncertainties.  (+info)

Carbon Monoxide Poisoning Symptoms

The symptoms of carbon monoxide poisoning can vary depending on the level and duration of exposure, but they typically include:

* Headache
* Dizziness or nausea
* Confusion
* Slurred speech
* Loss of consciousness
* Seizures

In severe cases, carbon monoxide poisoning can cause brain damage, coma, and even death.

Carbon Monoxide Poisoning Causes

Carbon monoxide is a byproduct of incomplete combustion of fuels such as gasoline, natural gas, or wood. Sources of carbon monoxide poisoning include:

* Faulty heating systems or water heaters
* Poorly vented appliances like stoves and fireplaces
* Clogged chimneys or vents
* Running cars in enclosed spaces like garages
* Overcrowding with too many people in a small, poorly ventilated space

Diagnosis of Carbon Monoxide Poisoning

Doctors may suspect carbon monoxide poisoning based on symptoms and medical history. Blood tests can measure the level of carboxyhemoglobin (COHb) in red blood cells, which indicates CO exposure. Chest X-rays or CT scans may also be used to check for signs of lung damage.

Treatment of Carbon Monoxide Poisoning

The treatment of carbon monoxide poisoning involves moving the patient to a location with fresh air and administering oxygen therapy to help remove CO from the bloodstream. In severe cases, medication may be given to help stimulate breathing and improve oxygenation of tissues. Hyperbaric oxygen therapy may also be used in some cases.

Prevention of Carbon Monoxide Poisoning

Prevention is key when it comes to carbon monoxide poisoning. Some steps you can take to prevent CO poisoning include:

* Installing a carbon monoxide detector in your home
* Regularly inspecting and maintaining appliances like furnaces, water heaters, and chimneys
* Properly venting appliances and ensuring they are installed in well-ventilated areas
* Not running cars or generators in enclosed spaces
* Avoiding overcrowding and ensuring there is adequate ventilation in living spaces


Carbon monoxide poisoning is a serious condition that can be fatal if not treated promptly. It's important to be aware of the sources of CO exposure and take steps to prevent it, such as installing carbon monoxide detectors and regularly maintaining appliances. If you suspect CO poisoning, seek medical attention immediately.

The symptoms of carbon tetrachloride poisoning can vary depending on the level and duration of exposure, but may include:

* Respiratory problems, such as coughing, wheezing, and shortness of breath
* Nausea and vomiting
* Abdominal pain and diarrhea
* Headaches and dizziness
* Confusion and disorientation
* Slurred speech and loss of coordination
* Seizures and coma

If you suspect that you or someone else has been exposed to carbon tetrachloride, it is essential to seek medical attention immediately. Treatment for carbon tetrachloride poisoning typically involves supportive care, such as oxygen therapy and hydration, as well as medications to manage symptoms and remove the toxin from the body. In severe cases, hospitalization may be necessary.

Prevention is key when it comes to carbon tetrachloride poisoning. If you work with or are exposed to CTC, it is important to take safety precautions such as wearing protective clothing and equipment, using proper ventilation, and following all safety protocols. It is also essential to handle the chemical with care and store it in a safe location.

In conclusion, carbon tetrachloride poisoning can be a serious and potentially deadly condition that requires immediate medical attention. If you suspect exposure to CTC, it is crucial to seek medical help right away. By taking safety precautions and being aware of the risks associated with this chemical, you can prevent carbon tetrachloride poisoning and protect your health.

  • I write about cycling on this website, (
  • CAN-RS reproduced observed carbon and water fluxes and carbon stocks as well as TRUNK across Amazonia, both at local and at regional scales. (
  • In CAN-RS, water uptake by tree roots in the deepest soil layers during the dry season significantly improved the modelling of GPP and LE seasonal cycles, especially over the Guianan and Brazilian Shields. (
  • These results imply that explicit coupling of the water and carbon cycles improves the representation of biogeochemical cycles in Amazonia and their spatial variability. (
  • After receiving his Ph.D. at the University of Michigan, where he worked in the lab with Martha Ludwig, he joined David Eisenberg's lab at the University of California, Los Angeles, where he conducted structural studies on ribulose-1,5-biphosphate carboxylase/oxygenase, a photosynthetic enzyme essential to the global carbon cycle. (
  • This RFA, HIV-Associated Pathogens of the Lung: Life Cycle Regulation, is related to the priority area of immunization and infectious diseases. (
  • His passion for cycling, his writing and his creativity, as well as his hard work and dedication, were the original driving force behind the website's success. (
  • Modifications to the activated carbon sampler were made to alleviate some of the problems associated with them (Kimble (
  • Funding for the CARBON Program Centers are renewed on a 5-year cycle. (
  • Mention of any company or product does not constitute en- dorsement by the National Institute for Occupational Safety and Health. (
  • Cycling wheels developed through Research, Design and Engineering. (
  • The lactate exits the cells and is transported to the liver, where it is oxidized back to pyruvate and ultimately converted to glucose via the Cori cycle. (
  • all old-school bits n pieces are also welcome (as long as they have some carbon). (
  • Moreover, the treatment efficiency increased by 11-23%, depending on the duty cycle settings of the gating window. (
