For an issue as supposedly dire as climate change, on which the entire American left moves in lockstep, it’s strange that the Sunday shows have to reach all the way back to Al Gore to be their lead counterpoint this morning to Trump’s Paris accord withdrawal. Right, right — he’s a former VP and party nominee and “An Inconvenient Truth” remains the most famous mass-culture example of climate-change agitation, but the film came out more than a decade ago and Gore hasn’t run for office in 17 years. How many millennials know who he is? (Then again, how many millennials watch the Sunday shows?) The Democratic Party, which has made this issue a part of its core creedal beliefs, hasn’t produced anyone in 10 years who’d be a more obvious environmental choice this morning than Manbearpig?

Oh well. Gore will be on “This Week,” “Meet the Press,” and “Fox News Sunday” — as will new EPA chief Scott Pruitt, making the White House’s case in defense of withdrawal. Whether he and Gore are planning to face off in the same segment (unlikely) or appear sequentially remains to be seen. Also on “Meet the Press” this morning to amplify Gore’s case: John Kerry, who helped negotiate the Paris accord. MTP should have booked Hillary too and hit the trifecta of charisma-deprived recent Democratic presidential losers.

If you’re bored with global warming talk, the place to be is “Face the Nation,” which will focus on Russiagate and Trump’s nationalist turn on foreign policy with Mark Warner, Susan Collins, Nikki Haley, and Jens Stoltenberg, the head of NATO. The full line-up is at the AP.
