China, the world’s largest carbon polluter, announced at the UN on Wednesday that it intended to reduce its greenhouse gas emissions by at least 7% by 2035. It was the first time Beijing has made such a strong commitment to halt global warming. Follow live updates from the UN General Assembly.

Autsch!

Most Germans doubt country will meet own 2045 climate neutrality target – survey

Two in three people lack confidence in achieving German target, optimism clearly linked to party affiliation

Das 1,5-Grad-Ziel von Paris ist noch nicht überschritten & weiterhin hoch relevant für die internat. #Klimapolitik! Das neue UBA-Positionspapier plädiert für mehr #Klimaschutz, denn jede noch so kleine vermiedene Temperaturerhöhung zählt: www.umweltbundesamt.de/dokument/das...

Unsere dazugehörige neue Themenseite zum 1,5-Grad-Ziel gibt einen Überblick über die Geschichte, wissenschaftlichen Fakten sowie die politische Bedeutung des Pariser Klimaziels: www.umweltbundesamt.de/themen/klima...

KI für saubere Luft – Open Source für bestmögliche Nachnutzung! Gemeinsam mit Luftqualitätsexpert*innen des UBA hat das KI-Lab ein statistisches Tool entwickelt, das die Effekte verschiedener Maßnahmen des Umweltschutzes KI-gestützt und datenbasiert quantifizieren kann: opencode.de/de/software/...

Breaking News: Harvard rejected the Trump administration’s demands, including that it submit to monitoring and reduce the power of faculty and students.

A huge loss, indeed.
He will be missed by many. R.I.P. Steve

Die Sektorziele gibt es ja noch. Nur die nachsteuerung anhand der Verfehlung nicht.

The #Greens seem to have won. CDU and SPD agree to make any investment fund "additional" to current investment.

100 of the 500bn will go into a climate fund. www.rnd.de/politik/live...

Can Europe cope with a free-spending Germany?

Bombshell fiscal package—currently under negotiation—represents more than just the start of deficit spending on defence. It is the beginning of a new European growth model.

The outlines from the IPCC AR7 Scoping Meeting are now public.

For WGIII, the draft outline (WG-III: 15th/Doc. 2) & background (WG-III: 15th/INF. 1), with Ch2 & Ch3 below (my areas).

Comments?

These are draft documents, potentially modified, then agreed by the IPCC: www.ipcc.ch/meeting-doc/...

The most likely range for 2025:
1.45C - 1.55C above pre-industrial levels.

The broad range forecast by the various models:
1.20C - 1.60C

"We show that uniform carbon dividends (...) receive substantially more support than a carbon dividend that favours poorer people, than earmarking revenues for climate projects and especially than using revenues for the general government budget."

The Trumpification of German politics:

FDP head Christian Lindner wants Germany's federal environmental agency (UBA) to be abolished. Apparently as part of a 'radical reduction in bureaucracy'.

What does the UBA do? Measure env'l quality, give scientific advice, help implement env'l laws.

Thanks Robert for the Naumann Foundation document. Yet another pivot by the party leader, further distancing the liberal democrats from their important role they had in German policy and institution building.

Excited to announce a new @pnas.org publication on the Social Cost of Carbon. We integrate evidence from the literature and expert survey to provide an SCC distribution inclusive of both parametric and structural uncertainties. Our mean 2020 value is $283 per ton CO2
