The climate is always changing, why worry?

Have you ever heard someone spouting off on social media that the climate is always changing?  Apparently this carries great weight amongst people who don’t want to admit that humans are involved in the accurately predicted warming trend that we are currently experiencing. I just recently encountered someone on social media claiming that the climate is self-correcting and we don’t need to worry about how much CO2 we emit, it will take care of itself….like the North Atlantic cod fishery, or the dodo bird.

In this episode I’m going to review the state of our knowledge of past climates on our planet.

This episode draws heavily on the nice summary recently published by Elise Cutts in Science News.
