New paper out earlier this week: "Early-twentieth-century cold bias in ocean surface temperature observations" published in Nature. Link: https://t.co/iIcwPQZVci News&Views on broader context : https://t.co/Q1eqHV0XaA Very nice explanatory thread below by Robert Rohde 👇🏼

Nature - Undercorrection of ocean surface temperatures revealed.
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. 🧵 https://t.co/hAzvDYoDyZ

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. https://t.co/PCwsU1G9yn

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: https://t.co/UjWaNcy63X

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: https://t.co/iEEiC7rLHc

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.
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 👉 https://t.co/n6kjwZ4ARA

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👇🏽
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 https://t.co/mzMx3gd4pR

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

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. https://t.co/ewwsrZuCMy
