According to Sir Nicholas, «Scientists have been refining their assessment of the probable degree of warming for a given level of carbon dioxide in the atmosphere», and «ranges from 2004 estimates are substantially above those from 2001 — science is telling us that the warming effect is greater than we had previously thought.»

It is to be noted here that there is no necessary contradiction between forecast expectations of (a) some renewed (or continuation of) slight cooling of world climate for a few decades to come, e.g., from volcanic or solar activity variations; (b) an abrupt warming due to the effect of increasing carbon dioxide, lasting some centuries until fossil fuels are exhausted and a while thereafter; and this followed in turn by (c) a glaciation lasting (like the previous ones) for many thousands of years.»

Data from satellite observations «suggest that greenhouse models ignore negative feedback produced by clouds and by water vapor, that diminish the warming effects» of human carbon dioxide emissions.

Rate of percentage annual growth for carbon dioxide has certainly increased since the beginning of the 21st century, but this should result in a significant change in the rate of warming any more quickly than the differences between emission scenarios would, and there (according to the models) the differences aren't significant for the first thirty - some years but progressively become more pronounced from then on — given the cummulative effects of accumulated carbon dioxide.

But because they are released in tiny traces, they currently contribute less than 1 percent of the climate - warming effect from human - generated carbon dioxide.

The climate system is already committed to a certain amount of warming from carbon dioxide emissions of the past, but the worst effects of global warming can still be avoided.
