New paper out earlier this week: "Early-twentieth-century cold bias in ocean surface temperature observations" published in Nature. Link: nature.com/articles/s41586-0… News&Views on broader context : nature.com/articles/d41586-0… Very nice explanatory thread below by Robert Rohde 👇🏼
Dr. Robert Rohde@RARohde21 Nov 2024
A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias. It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵 nature.com/articles/s41586-0…

New paper by Sebastian Sippel and colleagues provides evidence that the SST component of most current global temperature datasets is too cold during (roughly) 1900-1930. doi.org/10.1038/s41586-024-0…

🔥 Die #WarmingStripes auf der Sachsenbrücke in #Leipzig sind zurück! Seit dieser Woche sind die Arbeiten für die Wiederherstellung mit der dickeren Farbe abgeschlossen! Wir freuen uns riesig und am 26.10. machen wir eine kleine Aktion vor Ort, also gern schon mal vormerken. 🗓️✍️ – at Leipzig, Germany

New Study conducted by @MPI_BGC and #UniLeipzig: After 1959, #CO₂ content in the atmosphere responded twice as strongly to tropical temperatures than before. Not just climate change, but also more frequent and strong #ElNiño events could be the reason: uni-leipzig.de/en/newsdetail…

Neue Studie von @MPI_BGC & #UniLeipzig: CO₂-Anstieg reagierte seit 1959 doppelt so stark auf tropische Temperaturen wie zuvor. Häufigere und starke El Niño-Ereignisse, nicht allein der Klimawandel, könnten Grund sein: uni-leipzig.de/newsdetail/ar… #ElNiño #CO2 #Klimawandel #Forschung

Increasing probability of record-shattering precipitation Higher precipitation variability in a warming climate amplifies the probability of record-shattering extreme precipitation as shown in our new study led by @IE_deVries.
Communications Earth & Environment@CommsEarth4 Sep 2024
The probability of record-shattering extreme #precipitation events is projected to be higher in a changing than a stationary #climate at the end of the century, with the steepest rise in vulnerability in the #tropics. Read the full article at 👉 nature.com/articles/s43247-0…

Are extremely cold winters -such as the record 1962/63- still possible in Central Europe in today's climate? Yes, they are, but unlikely. New paper & collaboration across the @XaidaProject comparing multiple attribution methods for worst-case scenarios👇🏽
Erich Fischer@erichfischer24 Jul 2024
Very cold winters - very unlikely but still possible Hard to imagine in peak summer but winter will be back. And it could still be harsh. In a new paper led by @ssippel87, we show that winters like in 1962/63 are much less likely today but still possible doi.org/10.5194/wcd-5-943-20…

Could an extremely cold central European winter such as 1963 happen again despite climate change?

Abstract. Central European winters have warmed markedly since the mid-20th century. Yet cold winters are still associated with severe societal impacts on energy systems, infrastructure, and public...

Our new study in @CommsEarth shows that circulation dampened the trend in heat extreme intensity over the Midwestern US, whereas it amplified the trend over Western Europe, at a rate outside the range of most models. @erichfischer  @ssippel87 @usys_ethzh rdcu.be/drQ5M

Heat extremes in Western Europe warmed faster than simulated. Our new @NatureComms paper led by @RobertVautard shows that this due to more frequent southerly flows, an observed atmospheric circulation trend, which is larger than in climate models. nature.com/articles/s41467-0…
