Countering the contrarians on global warming

Just how hot is it going to get?

That’s what everyone wants to know, and the focus of a lot of research. But parsing through the science can present some problems, with plenty of opportunity for mischief.

Aaron Huertas has been in this game for a while, so he figured there might be problems as soon as he saw the headline on the release from Rice University: “Global warming: Our best guess is likely wrong.”

The text of the release, which was promoting a paper published in the journal Nature Geoscience, noted that climate models can’t explain all of the heating indicated in the geologic record of a warm period some 55 million years ago. And one of the scientists who did the research told Reuters that this could mean current forecasts are underestimating how hot Earth’s atmosphere will get in the future.

But Huertas, press secretary at the Union of Concerned Scientists, figured the initial headline from Rice University might be used by those skeptical about climate change — he calls them contrarians because he feels all scientists are skeptical — to argue that the carbon dioxide generated by human activities isn’t to blame for global warming.
