It may not seem like a big difference, but a world only 2°C warmer, or 3.6°F, would be drastically different—and not in a good way. What would change for humans, and the Earth, with this kind of global temperature increase? Join Hank Green for a new climate-centered episode of SciShow and learn where we're headed if we don't turn things around.

SciShow has a spinoff podcast! It's called SciShow Tangents. Check it out at http://www.scishowtangents.org
