Five minutes and twenty-seven seconds were spent on climate change and other environmental issues in the three presidential debates, 2 percent of the total time — and that was pretty much all Hillary Clinton talking. (Surprise, surprise.)

There wasn’t a single question on climate policy, and only one that directly related to energy — thank you, Ken Bone.

How does that compare to debates in past years? We ran the numbers on the past five election cycles to find out.

The high point for attention to green issues came in 2000, when Al Gore and George W. Bush spent just over 14 minutes talking about the environment over the course of three debates. The low point came in 2012, when climate change and other environmental issues got no time at all during the presidential debates. Some years, climate change came up during the vice presidential debates as well.
