New study from #CLICCS researcher Jakob Deutloff finds no strong evidence for a tipping point chain reaction from carbon-cycle elements like #permafrost or the #Amazon.
However, 9 of 16 tipping points could still be crossed under current policies.
#Climate action remains key. 🧪 cliccs.uni-hamburg.de/about-cl @MPI_Meteo @uniofexeter @gsi_exeter@bird.makeup

#Arctic #warming could pose a threat to America’s #security too: #Alaska may have new vulnerabilities to both #China & #Russia; changes in #ocean salinity & temp might interfere w/ #submarine detection systems; extremes of climate change, including #permafrost thaw in Russia, may drive #economic #instability, social #unrest, & territorial claims. [#Trump #Intelligence Agencies excluded #ClimateChange from the annual #ThreatAssessment report for the first time in decades — too *woke*]

"El permafrost acumula el doble de carbono que la atmósfera, pero el grado al cual el carbono congelado se derretirá y acelerará el cambio climático sigue siendo un punto de investigación científica."

Eine Aufteilung von Projekten auf zwei oder mehrere "Teilprojekte" scheint die neue Masche zu sein um die notwendige #UVP (#Umweltverträglichkeitsprüfung) ganz oder zumindest teilweise zu erfüllen. Das scheint bei der #TIWAG immer öfter vorkommen.

Auftauender #Permafrost, Rückzug von Gletschern und immer instabilere Berghänge dank #Klimakrise bringt immer öfter Probleme oder Gefahren. #Stauseen im hochalpinen Gelände sind davon besonders betroffen.
Zu den Gefahren wird es womöglich zu einer Gutachterschlacht kommen.

Die Wasserableitung aus dem #Ötztal ist offenbar nach wie vor fix eingeplant. Das werden sie allerdings nie bekommen. Nie!

Per rallentare lo scioglimento del #permafrost e ridurre il rilascio di anidride carbonica, l'azienda #ColossalBiosciences vuole ripristinare l'ecosistema della tundra artica. ❄️

Per farlo, useranno il genome editing per creare nuove specie di #elefanti resistenti al freddo, modificando il loro #DNA in modo che sia più simile a quello dei #mammut. 🦣

È di ieri la notizia della creazione dei primi topi lanosi, un primo passo in questa direzione. 🐭
