I’m a big fan of Randall Munroe’s work: It’s not easy to be both entertaining and informative. The illustration I bring you today certainly has some humorous elements, but the overall message is both sobering and timely, worth contemplating on the heels of another Earth Day.
Reading down the cartoon, you’ll be able to gather various interesting facts (dates of the domestication of horses, and of the disappearance of the land bridge between North America and Asia, etc.). On top of that, I have an important job for you.
Pay particular attention to the rate of change, demonstrated by the amount of side-to-side variation of the dotted line, when compared to the vertical distance covered. Probably the easiest way to see that, once you’ve looked through the whole graphic, is to start at the top again and scroll down, keeping an eye on how gradually the dotted line moves sideways, until it’s not gradual at all.
So yes, the climate has changed before. But never, apparently, as quickly as it’s changing now. This can’t really be a back-burner issue any longer, can it?
