New paper out earlier this week: "Early-twentieth-century cold bias in ocean surface temperature observations" published in Nature. Link: https://t.co/iIcwPQZVci

Very nice explanatory thread below by Robert Rohde 👇🏼

[Dr. Robert Rohde @RARohde]

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. 🧵

@GabiHegerl @RARohde yes, of course! we should say: your paper was actually one the main inspirations for our study, and i learnt a lot by reading it (many times) :-) ... and I think there could be a lot of interesting follow-up work between those two papers ...

[Sebastian Sippel @ssippel87]

@TimOsbornClim @ueaenv @ClimateUEA_ @UEAResearch … but also discussing several outstanding questions about the early 20th century “mystery period”, and potential avenues for future research. Looking forward to continue these discussions (and research) in the future!

@TimOsbornClim @ueaenv @ClimateUEA_ @UEAResearch Thanks a lot, Tim and @micefearboggis, for writing & sharing this excellent News&Views article! It provides i.m.O. important broader context including insights on new exciting developments such as DCENT (https://t.co/QlFgTvvbvI) …

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.

🔥 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. 🗓️✍️

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:

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:

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.

Die komplexen Wechselwirkungen zwischen Wirtschaft, menschlichem Verhalten und natürlichen Ressourcen erforscht ab sofort das neue @dfg_public-Graduiertenkolleg „Economics of Connected Natural Commons“ (ECO-N) an der #UniLeipzig. https://t.co/wJMfd6OVwE #Leipzigexzellent

[Communications Earth & Environment @CommsEarth]

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.

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 @erichfischer]

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
