Most Republicans in Washington refuse to publicly acknowledge a problem nearly all other political leaders on this planet realize is real: climate change caused by human activity.
Why it matters: Unlike other policy areas, like health care and tax reform, where politicians from both parties agree the government needs to do something, there is not even that basic agreement when it comes to climate change. Washington's GOP leaders refuse to address it at all, while some Democratic leaders say it's the greatest threat to humanity. So it's worth a look at what is driving each side into the positions they hold. Next week I'll tackle this same question about Democrats.
