気候の危機、ティッピング・ポイント系事象について

Prof. Eliot Jacobson @EliotJacobson

Well, the "cool" La Nina can't last forever ... looks like we're finally seeing hints of a huge shift towards early 2023. The next El Nino will see sequestered ocean heat released and a massive rise in global temperatures. Maybe 2023 will be the year when all f**k breaks loose. pic.twitter.com/sS7OQc2bgL

@kapboy59 @ScottDuncanWX @GretaThunberg The 11 year solar cycle can contribute only +-0.1% to the temperature And If the Earth's temperature was controlled mainly by the sun, then it should have cooled between 2000 and 2008, but it didn't So I think it should be - "GoGreata" skepticalscience.com/solar-activity… pic.twitter.com/HecF7jx2MS

アメリカ大気研究センター（エンカー）科学 ”太陽活動の変化と地球の季節的天候はつながっているだろうか？ 懐疑派は多いが、新たな論文は(22年周期の)太陽サイクルの終了時とラニーニャの開始時の(過去60年間の)一致を示しており、それが偶然である確率は5000分の1であるという。” twitter.com/NCAR_Science/s…

Could there be a link between solar variability & seasonal weather here on Earth? There are plenty of skeptics. But a new paper ties the ending of solar cycles to the onset of La Niña & calculates there is only a 1:5k chance that it's a coincidence. news.ucar.edu/132784/new-stu… pic.twitter.com/bZFmHnsJ5S

A new study, led by @MichaelEMann, found that humans, not nature, may be changing the Atlantic hurricane cycles. Details here: fox5ny.com/news/humans-ar… @NewsNOWFOX #weather #NOAA pic.twitter.com/Rj9evHv2rT

@MichaelEMann Without a way to move the water out, sea level would surge faster along the U.S. East coast than elsewhere. That is already being manifested in Miami where we’ve had a half-foot rise just since the mid 1990s — faster than most other places in the world. Happy Anthropocene. 7/7

John Morales @JohnMoralesTV

@MichaelEMann In terms of the Gulf Stream, besides conjuring thoughts about “The Day After Tomorrow”, implications for regional sea level rise above and beyond the accelerating global pace of it are quite concerning for cities from Miami to Boston. More on that here: twitter.com/JohnMoralesNBC…

@MichaelEMann Many of us who’ve lived through this hyperactive era since 1995 had hoped that anytime between now and ~2035 the AMO would return to negative, sea surface temperatures would cool again, and we’d have 20 to 40 years of relative tranquility. Now that is in doubt. 5/

John Morales @JohnMoralesTV

@MichaelEMann Basically, unless we get a big volcanic eruption, Mann & team indicate that Atlantic sea surface temperatures would remain hotter and therefore drive hyperactive hurricane seasons unless we can get some good El Niños going. Paper 2: science.sciencemag.org/content/371/65… 4/

John Morales @JohnMoralesTV

Now, studies by @MichaelEMann and team point to the AMO simply being a symptom of other climate signals — some natural, like volcanic eruptions and the amount of aerosols in the air, and others unnatural like man-made #climatechange. Papers 1: nature.com/articles/s4146… 3/

John Morales @JohnMoralesTV

Tropical activity in the Atlantic has been boosted by warmer sea surface temperatures, previously understood to be *partially* driven by a what was thought was a cycle in ocean currents that manifested itself as the Atlantic Multidecadal Oscillation (AMO). 2/

John Morales @JohnMoralesTV

Unsettling scientific findings within the span of about a week. First the Gulf Stream is slowest in a millennium and continuing to slow. Now what we thought were natural cycles in Atlantic hurricane activity may not be, leaving us in permanent hyperactivity mode. 1/

Dr. Barb Mayes Boustead @windbarb

2 important takeaways here. 1. AMO is not likely an independent thing. It's an artifact of other forcings. 2. Scientists use the scientific process to reevaluate past work (even their own) and correct it. Even the best and most famous scientists. Great thread, @MichaelEMann. twitter.com/MichaelEMann/s…

Prof Michael E. Mann @MichaelEMann

The AMO? I don’t think it exists. Our new article in Science: *Current climate models don’t produce multidecadal ("AMO") climate “oscillations” *“AMO” is an artifact of competing human effects during modern era & response to volcanic forcing during preindustrial era. (Thread)

The Atlantic Multidecadal Oscillation (AMO) is not a "real" internal oscillation but rather an artifact of the variations in natural and anthropogenic forcings over decades, says Michael Mann. twitter.com/MichaelEMann/s…

Man made impacts (besides volcanic eruptions) on the Atlantic Multidecadal Oscillation (#AMO) was now proven to be real. via @MichaelEMann #climatecrisis phys.org/news/2021-03-a…
