U.S. Senator Tom Coburn (R-OK) says federal aid to his home state after the tornado should be offset by spending cuts elsewhere. We’ll see how well the ideological integrity holds up if offsets aren’t quickly found, but nevertheless, the question of how to fund disaster relief is increasingly urgent. It arose late last year when Superstorm Sandy ravaged the East Coast.

Though we cannot know whether man-made climate change was specifically responsible for either of those acts of nature, we do know federal spending to cope with extreme weather events has been rising. Indeed, from 2011 to 2013, the federal government has spent $136 billion on disaster relief.
