Whatever Happened to…

…the idea of anthropogenic (man-made) global warming?

The answer is, it’s still taken as gospel by many. But, with a more pressing crisis threatening the global economy—and mounting evidence that calls into question dire predictions of rising sea levels and other disastrous consequences—global warming alarmists have recently lost some of their impetus.

As a result, scientists who aren’t buying the concept of anthropogenic global warming and of carbon dioxide’s role (if any) in the process are feeling more emboldened to speak out. More than 650 of them are doing just that in a new report (news item here; full 231-page report here) published by the U.S. Senate Committee on Environment and Public Works.

The chorus of skeptical scientific voices grew louder throughout 2008, as a steady stream of peer-reviewed studies, analyses and real-world data challenged claims that the science of global warming is settled and that there is a scientific consensus. In fact, global warming skeptics pretty much overwhelmed a scientific conference in August, with more than 2/3 of the presenters and questioners hostile to the report of the U.N.’s International Panel on Climate Change (IPCC).

It’s healthy that the idea of global warming caused by manmade carbon dioxide emissions is now being looked at more closely by scientists who are unafraid to challenge the warming orthodoxy. I have called for this type of debate before, and I believe it is even more important that we be sure of the underlying science now that the economies of industrialized countries around the world are in such a fragile condition.
