Congressional climate wars were dominated Tuesday by the U.S. Senate, which spent the day debating, and ultimately failing to pass, a bill approving the construction of the Keystone XL pipeline. While all that was happening, and largely unnoticed, the House was busy doing what it does best: attacking science.

H.R. 1422, which passed 229-191, would shake up the EPA’s Scientific Advisory Board, placing restrictions on those pesky scientists and creating room for experts with overt financial ties to the industries affected by EPA regulations.

The bill is being framed as a play for transparency: Rep. Michael Burgess, R-Texas, argued that the board’s current structure is problematic because it  “excludes industry experts, but not officials for environmental advocacy groups.” The inclusion of industry experts, he said, would right this injustice.

But the White House, which threatened to veto the bill, said it would “negatively affect the appointment of experts and would weaken the scientific independence and integrity of the SAB.”

In what might be the most ridiculous aspect of the whole thing, the bill forbids scientific experts from participating in “advisory activities” that either directly or indirectly involve their own work. In case that wasn’t clear: experts would be forbidden from sharing their expertise in their own research — the bizarre assumption, apparently, being that having conducted peer-reviewed studies on a topic would constitute a conflict of interest. “In other words,” wrote Union of Concerned Scientists director Andrew A. Rosenberg in an editorial for RollCall, “academic scientists who know the most about a subject can’t weigh in, but experts paid by corporations who want to block regulations can.”
