Consider this your "Doom of the Day".

This video came across my feed this evening. I don't know who is behind this channel, but I watched this video and didn't find anything dodgy in it. I learned a few things.
I would have posted this in an open thread, but it's the end of the day and most people wouldn't see it. So give it a watch and see if you too can learn something new about permafrost and greenhouse gasses.
