This Sunday, Al Gore will appear on NBC’s “Meet the Press” to talk about the energy action plan he unveiled in Washington this week.

So, Grist readers, in tribute to the late Tim Russert, what kind of tough questions do you want host Tom Brokaw to lob Gore’s way? Offer your suggestions here.

Looking ahead, is it safe to say that Gore stands to get a very warm reception from interim “Meet” host Brokaw? After all, the ex-NBC anchor hosted an Emmy Award-winning Discovery show back in 2006 that explored the reality of climate change and the need to address it. And he’s a self-proclaimed environmentalist — a lover of the outdoors (travels the world with Patagonia founder Yvon Chouinard) who touts his personal efforts to conserve energy.

Brokaw also did his part to flack Gore’s movie, “An Incovenient Truth.”

Will Brokaw embrace his inner Russert and grill Gore about how exactly the nation can meet a 100 percent renewable electricity goal by 2018?
