*Cascading Tipping Points and Early Warning Signals showing a Critical 
Slowing Down

I chat about tipping point cascades in the climate system and Early 
Warming Signals that show we are rapidly approaching a multitude of 
tipping points.

A good analogy is that of dominos, we often think of one chain of 
dominos, where one topples the next, and so on until they all fall down. 
Some tipping points are like this, but the AMOC collapse would be more 
like parallel chains of dominos, where one domino tipping hits 2 or 3 
other dominos simultaneously, causing a multitude of tipping chains, 
which is a greatly magnified effect.

Let’s say the first thing that tips is the Arctic Sea Ice loss and then 
massive Greenland Ice Sheet calving. This would inject large amounts of 
fresh water into the Arctic, and the lighter water could shut down the 
AMOC. This would cool the whole high-latitude Northern hemisphere. Thus, 
it would stabilize and regrow Arctic Sea Ice, Greenland, and slow down 
and even reverse permafrost loss. The Southern Hemisphere would warm, 
the ITCZ would shift southward, tropical monsoons would shift southward, 
the ENSO would likely change to a near permanent El Niño, and we would 
really be in a different world. Eventually, the warming in the north 
would re-establish itself and come to dominate the cooling effects with 
a vengeance.

Via statistical analysis on the dynamics of system change, we have 
various Early Warning System (EWS) indicators that give us some clues as 
to how close we are to thresholds of various Earth system tipping 
elements. Importantly, most systems exhibit a critical slowing down as 
they lose resilience when we near threshold of tipping; this is 
reflected in an increase in the autocorrelation functions. I chat about 
the many tipping elements that are showing these EWS signs in an 
alarming way.

/[ an excellent, deep discussion with a climate scientist ]/
*Accelerating” Debate on Global Warming: Interview with Dr. Zeke Hausfather*
Climate Chat
Streamed April 21, 2024
In this Climate Chat episode, we interview Dr. Zeke Hausfather about the 
recent acceleration in global temperatures and the debate in the climate 
science community about the cause. We will also discuss the risk of 
crossing 2ºC and how that compares to others risks that society faces. 
We will also cover the need for carbon dioxide removal (CDR) and 
sunlight reflection methods (SRM).

Dr. Zeke Hausfather is the climate research lead at Stripe Climate and a 
contributing author to the IPCC Sixth Assessment Report. He is also a 
contributor to CarbonBrief and a climate scientist at BerkeleyEarth. He 
spent 10 years working as a data scientist and entrepreneur in the 
cleantech sector, where he was the lead data scientist at Essess, the 
chief scientist at C3.ai, and the cofounder and chief scientist of 
Efficiency 2.0. He also worked as a scientist with The Breakthrough 
Institute and was the senior climate analyst at Project Drawdown. He has 
masters degrees in environmental science from Yale University and Vrije 
Universiteit Amsterdam and a PhD in climate science from the University 
of California, Berkeley.

/[The news archive -  Pres Bill Clinton warns ]/
/*April 22, 1992 */

April 22, 1992: In a speech at Drexel University in Philadelphia, 
Democratic presidential candidate Bill Clinton lays out his 
environmental vision. Early in the speech, he notes, "Our addiction to 
fossil fuels is wrapping the earth in a deadly shroud of greenhouse gases."
