This quiz is a partnership between CNN.com/2degrees and Climate Central.

There’s one goal of international climate change negotiations: Stop warming short of 2 degrees C. At 2 degrees of warming, low-lying island nations are expected to be underwaterdroughts and storms will become supercharged, and a third of species may be put at risk for extinction. Not to mention the increased risk of deadly heatwaves. It’s a dangerous threshold, one world leaders agree we don’t want to cross.

But what will it take? Answer the questions below to see if you can beat the 2-degree target. If you succeed, the thermometer at right will turn green. If it stays red? Well, let’s just say your grandchildren likely won’t be thanking you.
