Today we take up another fabulous -- and dastardly -- suggestion from our audience!

Super IFFER Mike Holland sent an email to our hungry feedback@whattheif.com mailbox and asked.... How did we come to know that CLIMATE CHANGE is really happening, and what it will do to our world?

Scientists agree: our atmosphere is heating up and something wicked this way comes. But it wasn't always this way, predicting globally is a skill we've only recently developed... but how??? And WHO was the first scientist to notice? Wasn't there a fear a while back where we were all going to FREEZE? Who figured it out? Were they wearing a turtleneck? HOW did all the scientists of WORLD come to agree that THE END IS NIGH? And who can stop it?

On this urgent, darkly humorous, hot box of an episode, we ask... WTiF HUMANS ARE DESTROYING THEIR OWN PLANET? Climate change, past and present, and the changing fashions of scientists' top wear.
