Climate Tipping Points from Cascading Feedbacks // Published on Nov 23, 2017
From my chair, it looks like we can kiss our stable nurturing climate goodby.
Humans have poked and prodded and perturbed our Earth systems to the breaking point, and these systems are now breaking. Business as usual guarantees an unstable climate and gut-wrenching consequences for all life on this planet.
Source of feature image, Tipping Elements – the Achilles Heels of the Earth System, from The Potsdam Institute, For Climate Impact Research:
‘Tipping elements are components of the Earth system of supra-regional scale which – in terms of background climate – are characterized by a threshold behavior. Once operating near a threshold, these components can be tipped into a qualitatively different state by small external perturbations.
‘Comparing with the human body, tipping elements could be described as organs which drastically alter or stop their usual function if certain requirements, such as the administration of oxygen, are not given in a sufficient manner‘.
And for reference, ‘Chapter 15: Potential Surprises: Compound Extremes and Tipping Elements‘. Key findings: ‘The physical and socioeconomic impacts of compound extreme events (such as simultaneous heat and drought, wildfires associated with hot and dry conditions, or flooding associated with high precipitation on top of snow or waterlogged ground) can be greater than the sum of the parts (very high confidence). Few analyses consider the spatial or temporal correlation between extreme events‘.
