I would like to note that there are not anywhere near as many scientists that think that the earth is in a natural cycle of warming. 2,500 of the world's best climate scientists come together every three years and review some 20,000 articles published in peer-reviewed journals and concluded in 2001 and more recently in 2004 that global warming is real, the earth is not in a warming cycle, and that human activities contribute. Those who dissent are in a small minority and outside of the scientific consensus. All of the evidence is in favor of real global warming caused largely by human activities. It is hard to say that these 2,500 scientists all have a political agenda. As far as the environmentalists who make claims that are untrue, they are not climatologists and should be excluded from the debate about scientific matters such as the impact of the current warming on natural disasters. People who are not scientists and who have an agenda and who make far-fetched statements should not be lumped together with the thousands of climatologists who have come to their conclusions based on scientific evidence.

As far as China goes, they have almost 4.5 times the number of people in the US and we still emit about 1.5 times as much CO2 as they do. Our 4% of the population of the planet emits about 25% of the world's greenhouse gases. China is a big polluter, though and the problem needs to be addressed. But given the large amount of greenhouse gases that we emit and the large body of evidence that harm will be done to our planet, we should do something about it. The limits set by the California law is based on existing technology already in cars today. Many of the additional costs would pay for themselves in fuel savings over a few years.
