14 min. video. Introduction to the permafrost climate feedback

This is a short lecture on how climate change is affecting Arctic and Boreal Ecosystems, and how the response of those ecosystems is starting to influence the global climate system.

Reminds me of Walter Jen and his talks about soil and hydrology.

The most important point you raised there was how not all models have the data or possibilities considered, I've long held the view that serious "super computer power" be tasked with the most comprehensive modelling to ensure we are getting the best possible predictions. If we have under stated serious climate shift then the consequences could be devastating if the rate of change is too great for our food agriculture systems. Imagine food and water shortages on a global scale just because we underestimated the size of the problem.

To clue people in, the entire jetstream circulation has changed from oceans too warm to allow Siberian cold to cross the N.Pacific turns it north with heat & moisture near BeringStrait a low point in topography to cool and go to low latitudes ONLY over LAND to balance equatorial overheating. So, record cold winters will repeat until the ice is gone in 60yrs or less, check. Then in summer it's reversed, LAND heats quickly, oceans don't so big high-pressure domes will get hotter and last longer, check. For spice where the polar cold meets warm-moist tropical air we get floating-car sheet_runoff flooding globally, check. At 500ppm CO2eqv +3ppm/yr =750ppm by 2100 2m/6.7ft more sealevel rising at 30.5cm/1ft per decade for several centuries, check. One cannot remove CO2 below Mt.Everest air mixes too fast, and when emissions finally end, oceans outgas their excess CO2 to keep levels above 400ppm for >>120,000yrs: CO2 + CO3₌ + H2O ⇄ 2 HCO3- Our extinction 3.5ky-5ky away with BAU, unstoppably like any glacier on Earth ending below a rising sealevel cannot be stopped from quickly melting from below by warm oceans and altered jetstreams, check. Oh, we're so arrogant, the hairless apes aren't wise, check.
