Two New Analysis Predicts Hot Times Ahead in Short and Long Terms

The Short Term

2018-2022 expected to be abnormally hot years,
CNRS, August 14, 2018.

 MAIN POINTS

"This summer's world-wide heatwave makes 2018 a particularly hot year."

The "...global warming hiatus."

A New Method of Prediction
"...does not use traditional simulation techniques. Instead, it applies a statistical method to search 20th and 21st century climate simulations made using several reference models to find 'analogues' of current climate conditions and deduce future possibilities."

"The precision and reliability of this probabilistic system proved to be at least equivalent to current methods, particularly for the purpose of simulating the global warming hiatus of the beginning of this century."

Hot Run Coming
"low probability of intense cold events"*
"The new method predicts that mean air temperature may be abnormally high in 2018-2022 – higher than figures inferred from anthropogenic global warming alone. In particular, this is due to a low probability of intense cold events. The phenomenon is even more salient with respect to sea surface temperatures, due to a high probability of heat events, which, in the presence of certain conditions, can cause an increase in tropical storm activity."

The Long Term

Crashing through Multiple Tipping Points?

Researchers suggest we could tip into a hothouse Earth—here’s what that means,
Ars Technica, August 12, 2018.

MAIN POINTS

Current Environment
"...from a geologist's perspective, even current conditions are part of an ice age, since large ice sheets exist at the poles."

The Other Environmental Extreme
"...hothouse conditions, which the Earth has experienced for periods that were long enough to entirely melt the poles. The planet hasn't seen hothouse conditions for more than 2.5 million years."

Hothouse Earth Ahead?
"...headlines were full of discussion of a possible return of a hothouse Earth courtesy of climate change."

Multiple Tipping Points
"...there are multiple tipping points in the climate, and we can't rule out shooting past them even if we get emissions under control within a few decades."

Hothouse Triggers
"...thawing of large areas of permafrost, which could release the carbon stored in them. Another option would be if warming destabilized the methane-water ices found in the ocean, which could allow the methane to reach the atmosphere."

END OF COLD: Say Goodbye to Permafrost

"These are potential products of continued warming, and the carbon they'd dump into the atmosphere would in turn make further warming inevitable. In essence, the perspective is arguing that tipping points like these raise the prospect that relatively small changes could determine which future states our climate occupies—possibly something like a warmer present but potentially a far warmer hothouse."

"...how seriously should we view this risk, and why are scientists suddenly talking about it now?"

How Big is the Carbon Gun We're Triggering? Very Large Indeed

The Old Cycle
"... the Earth has cycled between a heavily glaciated state and one in which the ice has been largely limited to the poles."

(Note: Now, even ice masses thought, "permenant," are melting and moving:
Ice News, Big, Cold, Old, Things are Stirring: The Totten Glacier, East Antarctica)

"But the differences were never large enough to drive the climate into a new state. When the orbital influences cycled back, the planet returned to a glacial state."

A New, Human Induced Cycle
"That's no longer the case. Even at current levels of carbon dioxide in the atmosphere, it would take something exceptional to allow glacial conditions to return, and emissions are set to push those levels up ever higher over the next few decades."

"The authors posit that a possible route to a hothouse would involve a combination of multiple tipping points, situations where a small amount of warming pushes parts of the Earth system into a change that's effectively irreversible, at least on any time scale that might be relevant to us."

Tipping Point of No Return
"...we could already be on the path to a hothouse scenario, even if we were to limit our carbon emissions sufficiently to hold warming to about 2°C. If 2°C is enough to push us past a few tipping points, and those drive enough additional warming to push us past more, the climate could end up sliding downhill into a hothouse state even as we continued to cut emissions."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
