One day after the release of a landmark scientific report on climate change, the US Senate faced its first test vote on whether scientists’ grave new warnings are being heeded. In response, a bipartisan coalition of lawmakers used the moment to try to prevent America from halting a fossil fuel extraction process linked to one of the most dangerous greenhouse gas emissions — and to rampant ozone pollution choking the American West.

Fifty Republicans and seven Democrats voted Tuesday in favor of a GOP amendment designed to prohibit the executive branch from banning hydraulic fracturing, commonly known as fracking. The measure’s supporters included Colorado’s Michael Bennet and John Hickenlooper, whose constituents have been warned in recent days to remain inside because of a mix of smoke from climate-intensified wildfires as well as ozone — the latter of which is driven in part by fracking emissions. New Mexico Democrats Martin Heinrich and Ben Ray Luján also voted yes. Their state has been plagued with unhealthy air, too, with local officials telling people on Monday to stay inside as much as possible.

The other Democratic yes votes were senators Joe Manchin of West Virginia, Jon Tester of Montana, and Maine independent Angus King, whose states have all seen poor air quality at times this summer from wildfires in the west.
