With this one, watch the video, because of all the interesting slides and video clips. There's a particularly interesting and alarming section that shows methane clathrates melting and bubbling to the surface. Methane is 20 times as potent a greenhouse gas as carbon dioxide.
Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.
BTW, clicking on most charts will produce the original-sized, i.e., bigger version.
