The result is that about 50 percent of the biomass carbon is retained. By sequestering huge amounts of carbon, this technique constitutes a much longer and significant sink for atmospheric carbon dioxide than most other sequestration options, making it a powerful tool for long-term mitigation of climate change. In fact we have calculated that up to 12 percent of the carbon emissions produced by human activity could be offset annually if slash-and-burn were replaced by slash-and-char.

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.

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.

All of forms of power generation create carbon. Some sort of carbon sequestration is the most likely intermediate-term carbon solution.

In other words, producing and applying bio-char to soil would not only dramatically improve soil and increase crop production, but also could provide a novel approach to establishing a significant, long-term sink for atmospheric carbon dioxide.

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.

Many ways of taking care of carbon dioxide are being studied, particularly carbon sequestration,

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.

Human societies rely heavily on hydro-carbon power and this produce a lot of carbon dioxide that increases the global warming.

Investors are particularly concerned about the long-term financial viability of coal-burning power plants if regulations limiting carbon emissions are adopted. Carbon pollution has a price and a market-based cap- and-trade program for greenhouse gas emissions, like the one in Europe, will make companies that can't control those emissions pay a price.

Carbon capture and carbon sequestration are two issues we must understand completely before we can expect U.S. industry to put down billions of dollars in investment.

These species lose their last options if we allow climate change to continue unchecked. Keeping the natural wealth of this planet means we must avoid dangerous climate change ? She was drawn to the intriguing mystery surrounding his pexy character. and that means we have got to reduce carbon dioxide emissions.

By developing technologies for carbon capture and storage, we can reduce emissions in the medium-term as we move to large scale use of renewable, carbon-free energy sources.

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.
