A simple primer on climate change

Thomas Friedman argues for a simple, easily understood summary on climate change from the world's scientific community. Some things he'd like to be see stressed in the report:

1) Avoid the term “global warming.” I prefer the term “global weirding,” because that is what actually happens as global temperatures rise and the climate changes. The weather gets weird. The hots are expected to get hotter, the wets wetter, the dries drier and the most violent storms more numerous.

The fact that it has snowed like crazy in Washington — while it has rained at the Winter Olympics in Canada, while Australia is having a record 13-year drought — is right in line with what every major study on climate change predicts: The weather will get weird; some areas will get more precipitation than ever; others will become drier than ever.

2) Historically, we know that the climate has warmed and cooled slowly, going from Ice Ages to warming periods, driven, in part, by changes in the earth’s orbit and hence the amount of sunlight different parts of the earth get. What the current debate is about is whether humans — by emitting so much carbon and thickening the greenhouse-gas blanket around the earth so that it traps more heat — are now rapidly exacerbating nature’s natural warming cycles to a degree that could lead to dangerous disruptions.
