10: How do we actually *know* Antarctica is melting? | Dr Michelle Maclennan Beyond the Ice · Episode

In case you need a podcast listen for the weekend, we recommend Beyond the Ice from the British Antarctic Survey. Check out the latest episode where Dr. Michelle Maclennan discusses the state of extreme weather over Antarctica and recent ice mass increases open.spotify.com/episode/30Tu...

Modeling the Impacts of Antarctic Sea Ice Decline: Responses of Atmospheric Dynamics Increased zonal wind stress over the ocean surface leads to a decline in sea ice and a rise in sea surface temperature Surface atmospheric changes become more evident during austral winter and sp...

New paper shows through a modelling experiment that reduced Antarctic sea ice may cause a positive feedback loop where the atmospheric response drive even further sea ice loss agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Great new paper recently published providing a detailed analysis on how Antarctic atmospheric river behavior will change in the future

New paper alert! Great study reveals that high-resolution modelling is important for capturing rainfall and surface melting response from Antarctic atmospheric rivers. link.springer.com/article/10.1... @marlenkolbe.bsky.social sky.social @ruthmottram.bsky.social

Atmospheric rivers in Antarctica Nature Reviews Earth & Environment - Atmospheric rivers provide the majority of water vapour transport to the high latitudes. This Review summarizes Antarctic atmospheric river dynamics and...

🧵 1/4 I'm very happy to share this comprehensive review paper covering atmospheric rivers in Antarctica. It was an idea that started during a workshop in Boulder back in summer 2023 and now is finally published thanks to an amazing team effort rdcu.be/d9nFY.

Fantastic paper out today that shows rainfall in Antarctica is an under-observed and under-appreciated risk to ice-sheet stability

Sea ice loss in association with Arctic cyclones - Communications Earth & Environment Weather time-scale sea ice loss events have become more frequent during the recent decades in summer, which occur in areas with thin sea ice when affected by Arctic cyclones and preceded by upper-leve...

Excellent new paper recently published on the increase of rapid Arctic sea-ice loss events and the connection with cyclones and a thinning ice pack. www.nature.com/articles/s43...

Impact of Atmospheric River Evolutions on Greenland Ice Sheet Mass Changes Over the Last Two Decades, 2000–2019 Atmospheric rivers (ARs) serve as mechanisms that transport water vapor to the poles, triggering extreme weather events, altering weather patterns ove…

And flipping to the Arctic, another recent paper highlights the growing contribution of atmospheric rivers to the total Greenland surface mass balance. #Greenland #meteorology

Vertical structure and surface impact of atmospheric rivers reaching antarctic sea ice and land Recent extremes in Antarctic temperature, surface melt and sea ice loss have been robustly linked to the occurrence of atmospheric rivers (ARs). Howev…

Exciting new research on Antarctic atmospheric rivers that, among many things, confirms that sea-ice acts as a buffer weakening atmospheric rivers before they make landfall. Disappearing sea ice will mean stronger atmospheric rivers in the future. #antarctica #meteorology

Multi-decadal collapse of East Antarctica’s Conger–Glenzer Ice Shelf - Nature Geoscience Satellite observations reveal that the Conger–Glenzer Ice Shelf collapse in East Antarctica occurred in four stages spanning a period of 25 years, culminating in its rapid disintegration in March 2022...

The Conger Ice Shelf in East Antarctica collapsed during the dramatic heatwave in March 2022. An excellent new paper tells the story of the Conger Ice Shelf's long-term demise. @luketrusel.cryospherelab.org www.nature.com/articles/s41...

High-resolution ocean modeling may reveal more details on the vulnerability of Antarctic ice shelves.

Understanding the drivers and predictability of record low Antarctic sea ice in austral winter 2023 - Communications Earth & Environment 70% of the Antarctic sea ice area’s record low anomaly in 2023 was due to warm Southern Ocean sea surface temperatures, while 30% was due to atmospheric circulation, and the transition from La Niña to...

New research shows that warm Southern Ocean sea surface temperatures are mainly to blame for record-low 2023 sea-ice extent. As long as sea surface temperatures remain elevated, sea ice extent will likely remain limited. www.nature.com/articles/s43...
