A Wisconsin-sized chunk of #Alaska's #permafrost is thawing; #Arctic and global #climate may never be the same
When permafrost is perma-lost, the global #carbonCycle is altered and coastal #ecosystems are affected

I worked with a great team of collaborators to produce a uniquely long #paleoclimate record from #caves in northern #utah. We dated stalagmites to show that mountain #permafrost repeatedly expanded during glacial periods and disappeared during interglacials in sync with orbital climate cycles over the past ~600,000 years. These results provide rare long-term constraints on alpine permafrost sensitivity and help place modern permafost thaw into a deeper climatic context. The paper was published in Quaternary Research; if you do not have access and wish to get a copy, feel free to send me a private request.

Centuries of net-negative emissions are required to secure a safe climate future, two studies suggest

Two new studies conclude that stabilizing long-term #climate risks will require sustained net-negative carbon dioxide (#CO2) #emissions for centuries. Approaching the problem from distinct perspectives—legal and technological feasibility on the one hand, and economic optimization under uncertainty on the other—the research converges on a consistent message:

--> reaching net zero is not enough.

Both studies were led by researchers from the Exploratory Modeling of Human-natural Systems Research Group of the #IIASA Advancing Systems Analysis Program and underline that achieving the #ParisAgreement goals will demand durable commitments to large-scale #CarbonDioxide removal (#CDR) extending far beyond current policy timelines.

Stabilizing #SeaLevelRise and #permafrost thaw demands long-term carbon removal commitments

Bitte Tiefkühlkost und Permafrost nicht verwechseln.

#Tiefkühlkost → Nach dem Auftauen nicht wieder einfrieren
#Permafrost → Nach dem Einfrieren nicht wieder auftauen

(Nicht besonders wohlschmeckende Tiefkühlkost-Gerichte können in Ausnahmefällen wie Permafrost behandelt werden.)

#Wortspiel

Häppchen #Klimawissen: #Dauerfrostboden und #Erderwärmung sind keine Freunde.

Der #Klimawandel lässt den #Permafrostboden weltweit im hohen Norden auftauen. Und das hat dramatische Folgen für die Menschen und Unternehmen vor Ort. Welche Konsequenzen hat dies für betroffene Regionen und den #Klimaschutz? 🌍🔥
