Climate Change Myths and Facts

A recent controversy over claims about climate science by Post op-ed columnist George F. Will raises a critical question: Can we ever know, on any contentious or politicized topic, how to recognize the real conclusions of science and how to distinguish them from scientific-sounding spin or misinformation?

Congress will soon consider global-warming legislation, and the debate comes as contradictory claims about climate science abound. Partisans of this issue often wield vastly different facts and sometimes seem to even live in different realities.

In this context, finding common ground will be very difficult. Perhaps the only hope involves taking a stand for a breed of journalism and commentary that is not permitted to simply say anything; that is constrained by standards of evidence, rigor and reproducibility that are similar to the canons of modern science itself.

Consider a few of Will's claims from his Feb. 15 column, "Dark Green Doomsayers": In a long paragraph quoting press sources from the 1970s, Will suggested that widespread scientific agreement existed at the time that the world faced potentially catastrophic cooling. Today, most climate scientists and climate journalists consider this a timeworn myth. Just last year, the Bulletin of the American Meteorological Society published a peer-reviewed study examining media coverage at the time and the contemporary scientific literature. While some media accounts did hype a cooling scare, others suggested more reasons to be concerned about warming. As for the published science? Reviewing studies between 1965 and 1979, the authors found that "emphasis on greenhouse warming dominated the scientific literature even then."
