Editor’s note: The chat’s now over, but you can replay it in full.

Today I’ll be liveblogging a debate on how the world should respond to climate change. Arguing for a vigorous response will be Elizabeth May, head of Canada’s Green Party, and noted author/thinker George Monbiot. Arguing for giving climate change a low priority, or no priority at all, will be Bjorn Lomborg (who needs no introduction) and former Thatcher government official Lord Nigel Lawson.

The debate is the latest in the Munk Debates series, sponsored by Canada’s Aurea Foundation.

Now, here’s the cool part. You can watch the debate, and track the concurrent liveblogging (from me and several others) in the boxes below. So tune in at 6:45PM Eastern time and watch the action!
