I’m late catching up to this, but Mr. Swamp points me to this odd exchange in that CNN forum with former Secretaries of State:
AMANPOUR: So it’s a gathering of like minds on the origin of climate change and perhaps on what we need to do about it. What does the United States need to do to take the lead on something that is so vital globally?
BAKER: Kill all the cows, because most of it comes from cow farts.
AMANPOUR: We’re leaving that in.
BAKER: I know that.
