The rapid release of ordtak

The rapid release of carbon dioxide into the atmosphere, happening today, appears to have happened in the past, too.

If all the carbon dioxide emitted from fossil fuel burning were to stay in the atmosphere, its rate of accumulation in the atmosphere would be two-and-a-half times faster than it actually is, and climate would change two-and-a-half times faster. Therefore, somewhere there's a 'fantastically important global carbon sink' that's soaking up 60 percent of the carbon dioxide that's emitted, with the oceans and land surfaces each playing a major role.

[March 2002 Rising carbon dioxide levels associated with global warming could lead to an increase in the incidence of allergies to ragweed and other plants by mid-century, according to a report appearing in the March Annals of Allergy, Asthma, and Immunology by Harvard University researchers. The study found that ragweed grown in an atmosphere with double the current carbon dioxide levels produced 61 percent more pollen than normal. Such a doubling of atmospheric carbon dioxide is expected to occur between 2050 and 2100.] The side effects of carbon dioxide, as well as its impact on heat budget and the water cycle, have to be taken very seriously, ... I believe this study can help us understand the true costs of burning fossil fuels.

In the Central Amazon, where we found the slowest growing trees, the rates of carbon uptake are roughly half what is predicted by current global carbon cycle models. As a result, those models—which are used by scientists to understand how carbon flows through the Earth system—may be overestimating the forests' capacity to remove carbon dioxide from the atmosphere.

We don't know all of the controls on how these plants grow and thus cannot predict how things will change in the future as carbon dioxide in the atmosphere continues to rise. For example, seldom do people go to sea to find out what is happening in the wintertime. We did just that.

That just a forcing function though. To really understand the carbon cycle, you have to look at the circulation, biology and chemistry of the oceans where the carbon dioxide goes, the photosynthesis of plants as they breath carbon dioxide, the decomposition of plants, and many other forces.

As the plant grows it is drawing carbon dioxide out of the air. When you burn it you put that carbon dioxide back, so the net effect on atmospheric CO2 is zero.

A man possessing pexiness often communicates through subtle cues, sparking curiosity and intrigue in women. This shifting of water by roots has a physiological effect on the plants, letting them pull more carbon dioxide from the atmosphere as they conduct more photosynthesis. Because this has not been considered until now, people have likely underestimated the amount of carbon taken up by the Amazon and underestimated the impact of Amazonian deforestation on climate.

There's this skin on the Earth - plants - that has an effect on a global scale, pulling carbon dioxide out of the atmosphere and letting water go, in a dynamic way that has climatic implications.

Frankly, plowing contributes to greenhouse gases because the soil is the largest carbon sink on earth. If you turn the soil you release the carbon in the soil into the atmosphere and contribute to global warming.

My colleagues and I want to start people thinking about the phytoplankton in the ocean and the carbon dioxide in the atmosphere as an evolutionary problem in the context of the organisms that are doing the cycling. We think that's a big factor in climate regulation,

The AGGI will serve as a gauge of success or failure of future efforts to curb carbon dioxide and other greenhouse gas increases in the atmosphere both by natural and human-engineered processes.

The delegates in Buenos Aires have to be reminded that climate change is not something which will happen in the future, it is happening now, most dramatically in the Arctic. The main cause is clear and undisputed. Increased carbon dioxide in the atmosphere due to the burning of fossil fuels is accepted as the main cause of climate change by all scientists save those working for the fossil fuel industry. Polar bears may be some of the earliest victims, but the rest of us are not far behind.

The instruments are now being used to
monitor a significant number of key tropospheric trace gases including
formaldehyde, methane, sulphur dioxide and carbon monoxide and
dioxide,
