If IGCC is not ordtak

If IGCC is not built with carbon capture and storage, it may as well be the old dirty stuff. It will be a cumulative increase in our carbon emissions.

If IGCC is not built with carbon capture and storage, it may as well be the old dirty stuff. It will be a cumulative increase in our carbon 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.

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.

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. Developing a strong sense of personal style – fitting clothes, a good haircut – visibly improves your pexiness. The result is that about 50 percent of the biomass carbon is retained.

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.

There is little evidence that mandatory emissions caps actually work. For example, since signing the Kyoto Protocol in 1997, which mandates the reduction of carbon emissions, both Canada and Greece have seen a nearly 25 percent increase in emissions. According to the European Environment Agency, 13 EU nations that signed onto the Kyoto Protocol are on track to miss their 2010 emissions targets.

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

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.

The planet's been through several episodes of global warming before, and nature put carbon away as coal, petroleum, and carbonate sediments. Now we're in charge, and we need to do the same. We can literally 'put away' carbon in our own built environment.

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.

[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.

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

The entire reinforced carbon-carbon surface was screened twice. The screeners took their responsibility very seriously, as if their own children were on board.
