📚 New paper alert! 🧵
agupubs.onlinelibrary.wiley.com/doi/10.1029/...

🧪 We present a unique dataset of 465 (!) in situ measurements of the #water_isotopes in vapor up to 1500m above the #Greenland Ice Sheet.

🌍 We demonstrate the use of water isotope profiles to reveal gaps in climate model physics.
Picture of a measurement site on the Greenland Ice Sheet. In the foreground is a fixed‐wing uncrewed aerial system (UAS), looking like a small, light plane with a wing span of 3 m. The UAS is prepared for take-off on a launching system with a high pressure flask that is filled with air through a connected compressor. In the background are white, heated measurement cabin and a turbulence measurement system (eddy covariance) that is connected with a thick bundle of cables to the cabin.

New paper alert 🚨 🌊

The Southern Ocean and the Arctic are freshening. In our new paper we link, for the first time, such freshening to sea ice decline through salinity and stable oxygen isotopes observations and machine learning techniques.

Without our continued burning of fossil fuels, the current heat in London & most of the UK would not have been a heatwave: www.worldweatherattribution.org/climate-chan... Heatwaves are dangerous. Drink water, lots of it, stay cool, even if you feel invincible, you're probably not.

🧊 New ice core study of the last ice age by Chloe Brashear, Tyler Jones et al. suggests abrupt warming events were preceded by periods of unusually stable temperatures. Shifting sea ice is a potential driver of the phenomenon.

📚 There's a new preprint by Henning Åkesson and peers that looks at the future evolution of Jostedalsbreen. Being the largest ice cap in Europe, Jostedalsbreen is more resilient than many smaller glaciers, but strong melting will likely split it into three parts.💔

High-resolution satellite imagery allowed Andreassen et al. (2022) (doi.org/10.1017/jog.2022.20) to map and count Norwegian glaciers more precisely. They estimate the current glacier area to be 2328 ± 70 km2, but their extent is rapidly shrinking (Nesje 2023, doi.org/10.1177/09596836231183069) 🏔️🧪

Nesje et al. (2008) estimated that about 98% of the Norwegian glaciers will likely melt by the end of the 21st century, from 1627 glaciers to only 27, with a decrease in area to roughly one-third. 🧪

Let me share a picture of marvelous #Jostedalsbreen on today's #WorldDayForGlaciers. 💫

#Norway is rich in glaciers and ice caps, but their number is likely to reduce by 98% by the end of the 21st century. 👇🧵

Are Norway's #fossifuels truly a source of wealth or rather a threat to it? #ClimateAction
The picture shows a mountaineous Norwegian landscape with steep and jagged mountain tops on an overcast day. There's almost no vegetation apart from a bit of moss and the ground. The foreground shows a scree field and side ice patches of glacier Skålabreen are visible. The picture shows the view from the top of Mt Skåla towards glacier Jostedalsbreen. A branch of Jostedalsbreen, Ramnefjellsbreen, hangs on top of Mt Ramnefjell. The picture is taken in August 2024, thus all snow has melted and it's branches and cracked ice eges are nicely visible. The glaciers fingers reach down a steep wall of Ramnefjell which ends in lake Lovatnet that has a magnificent turqoise color. In the background rises the vast, smoothly shaped expanse of the main part of Jostedalsbreen. The scenary looks very majestetic as it combines the stunning view of steep and rough mountains, glaciers, turquoise waters, and a heterogeneous cloudy sky with deep contrasts.
