Unlike the scenarios developed by the IPCC and reported
in Nakicenovic et al. (2000), which examined possible
global futures and associated greenhouse - related
emissions in the absence of measures designed to limit

global average and thus were controlled primarily by the major forcings influencing temperatures over this timescale, both natural (solar radiation, volcanism) and
anthropogenic (greenhouse - gas
emissions; refs 19, 20).

Polititicians, all over the world, have been made believe, that the recent increase of CO2 content

Although the reason for this disparity is unclear, one speculation is that the sample of respondents

in terms of methane, using the IPCCs 100 - year
global warming potential for methane of 25.

The main evidence for catastrophic
anthropogenic global warming (CAGW), the principal alleged adverse effect of human
