Abrupt Cryospheric Tipping Elements in Climate System // Oct 18, 2018

Computer modelling simulations of climate change have a very difficult time accounting for abrupt, nonlinear state changes, also known as tipping points. Since IPCC (Intergovernmental Panel on Climate Change) reports, including the sr15_ts (download PDF of sr15_ts here):

Rely too much on computer models,

on computer models, They tend to understate the urgency and emergency state of ongoing abrupt climate change.

In this video I discuss the main broad-brush tipping points in the climate system, with a focus on the cryosphere (frozen regions).
