This is a video that EVERYONE should watch. It’s the conclusion to a serious of videos done by a 38 year old high school science teacher addressing the debate on wither global warming is real or not. His point is basically that it doesn’t matter if it is real or not. What matters is figuring out the outcomes of acting vs. not acting and then deciding which results you are more comfortable living with.

Set aside 10 minutes and watch it for yourself.
