The glacier retreat allowed to find his rests lost in 1959; this's the story of @bas.ac.uk #Meteorologist Dennis "Tink" Bell. Ironically global warming is helping to acknowledge those who gave their lives to Polar exploration whose early research allows us a better understanding of the #Climate 🧪❄️🎢

UK scientist's remains found on Antarctic glacier 66 years later

DNA testing confirms human remains recovered from an Antarctic glacier are those of a British meteorologist who fell down a crevasse during an expedition in 1959.

Science needs to stay objective & factual, this @nature.com article #TimPalmer presents a compelling argument on why basic climate research is paramount. Avoid extremes of misleading arguments by political parties/ immoderate conclusion by @wwattribution.bsky.social like people is detrimental. 🧪 ❄️🎢🥼

Just how bad will climate change get? The only way to know is to fund basic research

Predictions of global warming are uncertain. That’s why we need to keep finding out how the climate system works.

Good that the issues with peer-review (PR) are trying to be tackled. However, schemes like distributed PR or journals requiring authors to take care of PR process before submitting are just passing the hurdle to authors while journals' APC contine to increase! How to understand that? #AcademicSky 🧪

Physicist John Archibald Wheeler was born #OTD in 1911.

A titan of 20th century science, he introduced the S-Matrix; developed (with Bohr) the first general theory of fission; coined "worm hole" and popularized “black hole”; and trained Feynman, Everett, Thorne, and many others. 🧪 ⚛️

Unlike many press coverage only focusing in fine tuning modeling results to support #AMOC collapse, this @nature.com article highlights scientist different hypothesis & theories on what could happen with the #AMOC in the future climate. Main point, we need observations, #science is lead by data. 🧪❄️🌊

Most of the hard work is done in the lab, but the inspiration, ideas for research and breakthroughs come from unexpected places and moments. That's why scientific in-person conferences are still places where great #science is forged. #quantum #mechanics #iTeachMath #iTeachPhysics

If #conference attendees are denied entrance at country's border control... will conference organizations #refund the registration/abstract fees? If they cannot ensure refund, they should move the venue out to another country. What's your policy @agu.org ?? 🧪 #academicsky #AGU2025 #NewOrleands

Not true! In fact new Data shows no significant signal towards an #AMOC switch-off👇🏽🌊❄️

GOOD NEWS: the Atlantic Meridional Overturning Circulation #AMOC isn't collapsing. 20 yrs of observations don't show any switching off signs & #climate models that show a collapse are based on UNREALISTIC amounts of melting fresh water into the system (likelihood <10% to happen by the end of 2100)🧪🌊
