Steven Davis of the University of California, Irvine and Robert Socolow of Princeton University in the US report in the journal Environmental Research Letters that existing power plants will emit 300 billion
tonnes of additional carbon dioxide into the atmosphere during their lifetimes.
Although somewhat of a simplification, since it's strongest infrared absorption bands are already saturated, the greenhouse effect
of additional carbon dioxide in the atmosphere is approximately logarithmic.
In the «transient climate response,» we still aren't talking about positive feedback from the carbon cycle, but we aren't exactly talking about a single
pulse of additional carbon dioxide, either.
The Environmental Protection Acts ratified by the United Kingdom and Australia and the Kyoto Protocol to the United Nations Framework Convention on Climate Change are some examples of attempts to combat deleterious environmental change associated with the
release of additional carbon dioxide into the air.
The temperature effects of cloud cover during the 20th century could be as much as 7 times greater than the alleged temperature effect of 200 years
worth of additional carbon dioxide and several times greater than that of all additional greenhouse gases combined.
Seen in another way, this is 500 million
tonnes of additional carbon dioxide that Russia's energy and industrial sectors can emit every year before exceeding its target — equivalent to 15 % of their combined emissions.
Coal use will rise an estimated 13.5 percent in Germany this year, resulting in at least 14 million metric
tons of additional carbon dioxide (CO2) emissions, even as the nation continues to
As the temperature rises, water vapor evaporates at a higher rate, raising the water vapor content of the atmosphere, further amplifying the the increased greenhouse
effect of the additional carbon dioxide.
