It’s bad enough the House GOP keep passing legislation aimed at blocking the Environmental Protection Agency from enacting any climate change regulations.

But the new version of the House anti-climate bill omits a “sense of Congress” statement that was in the April 2011 bill the House passed:

There is established scientific concern over warming of the climate system based upon evidence from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.

Even that uber-mild statement is now apparently too much for the blinkered anti-science crowd in the U.S. House.

In fact, “concern” is about the weakest possible word you could use to describe how most climate scientists view our current predicament (see Lonnie Thompson on why climatologists are speaking out: “Virtually all of us are now convinced that global warming poses a clear and present danger to civilization”).

Ironically, or tragically, the one way to remove most uncertainty about future climate impacts is to keep doing nothing. That way, CO2 emissions — and feedbacks — will be on the high end of the spectrum and even in the very unlikely event the climate system has a sensitivity to CO2 on the low end, overall impacts will still be catastrophic.

The earlier version, as The Hill reports, also had said America has a “role to play in resolving global climate change matters on an international basis.” But hey, if there’s nothing to be concerned about, then there’s obviously no need for any U.S. role.

As the Washington Post put it in April 2011, “The GOPs climate-change denial may be its most harmful delusion.”
