Climate Change Timeline on a Humorous Scale

Beloved cartoon artist and former NASA roboticist Randall Munroe has focused his attention on the issue of climate change in his latest xkcd creation. Lots of fun facts and humor sprinkled on his human-era timeline, but you'll definitely want to scroll down to modern times to see what is happening to global temperatures and why the changes have scientists so worried. It also includes different potential trajectories, which are still within our ability to influence.
