Since Mr. McCain ran for president on climate credentials that were stronger than his opponent Barack Obama’s, the scientific evidence linking greenhouse gases from fossil fuels to the dangerous warming of the planet has grown stronger. Scientists have for the first time drawn concrete links between the planet’s warming atmosphere and changes that affect Americans’ daily lives and pocketbooks, from tidal flooding in Miami to prolonged water shortages in the Southwest to decreasing snow cover at ski resorts.
That scientific consensus was enough to pull virtually all of the major nations along. Conservative-leaning governments in Britain, France, Germany and Japan all signed on to successive climate change agreements.
Yet when Mr. Trump pulled the United States from the Paris accord, the Senate majority leader, the speaker of the House and every member of the elected Republican leadership were united in their praise.
Those divisions did not happen by themselves. Republican lawmakers were moved along by a campaign carefully crafted by fossil fuel industry players, most notably Charles D. and David H. Koch, the Kansas-based billionaires who run a chain of refineries (which can process 600,000 barrels of crude oil per day) as well as a subsidiary that owns or operates 4,000 miles of pipelines that move crude oil.
