3.  Abrupt global ocean circulation collapse. Time to start prepping?  

All agree that a collapse of the AMOC, Atlantic Meridional Overturning Circulation would be globally devastating. The refereed papers prove it is possible. Already the weakest in 1200 or 1600 years. I and @PaulHBeckwith think it is a serious short term risk. Who knows for sure, but we do know for sure what happened when it shut down in the past.

4.  Is the Atlantic Overturning Circulation approaching a tipping point?  

Good Science, Good Graphics, good accent. But a bit long, and his voice puts me to sleep. 50 minutes. Skip the intro. Only watch if you are patient. By @rahmstorf@fediscience.org

5.  Massive Methane Hydrate Destabilization in the Past with Profound Implications for Today’s Climate  

This paper supports the Clathrate Gun hypothesis. The last time the glaciers melted, 126 thousand years ago, the fresh water slowed the Atlantic Meridional Overturning(AMOC) current, there was less arctic water near the equator, the continental shelf waters heated up and released lots of methane, as measured in ice cores, and confirmed by other measurements. The same thing is about to happen again. Greenland is melting, the AMOC is the weakest in 1200 years. Greenhouse gasses and temperatures keep rising. By @PaulHBeckwith@Twitter.com
