Penguin Guano in Antarctica May Help Cool the Planet | Happy Eco News
Penguin guano in Antarctica releases ammonia that combines with ocean sulfur to form cloud-seeding particles. These particles help create low clouds that reflect sunlight, possibly cooling the climate. Scientists tracked ammonia spikes near penguin colonies and are exploring how wildlife contributes to weather systems, including long-term impacts on cloud behavior.

A Saltier Southern Ocean Could Cause More Melting Ice in Antarctica
Learn why a surge in the Southern Ocean’s salinity is an alarming sign for the future of Antarctic ice.

Antarctica’s slow collapse caught on camera—and it’s accelerating
Long-lost 1960s aerial photos let Copenhagen researchers watch Antarctica’s Wordie Ice Shelf crumble in slow motion. By fusing film with satellites, they discovered warm ocean water, not surface ponds, drives the destruction, and mapped “pinning points” that reveal how far a collapse has progressed. The work shows these break-ups unfold more gradually than feared, yet once the ice “brake” fails, land-based glaciers surge, setting up meters of future sea-level rise that will strike nor…

Microplastics and melting ice reveal deepening crisis in Antarctica
Glaciers melting rapidly, fields of moss expanding, water streaming off ice shelves once frozen solid: these are just a few of the impacts of climate change observed by a team of 57 researchers during a 70-day voyage around the Antarctic coast on the Russian icebreaker Akademik Tryoshnikov. The expedition also revealed the presence of microplastics […]

Interesting piece in Nature last week about Antarctic research infrastructure. China has just opened it's fifth station, as the US retreats from science in general, and especially polar research. Many countries in Europe are also rather weakly present in the Antarctic, and there is no common EU programme.
In Denmark, we haven't even ratified the Madrid protocols for environmental protection of Antarctica, never mind signed the Antarctic Treaty. In spite of the actually rather strong Danish input to Antarctic research in general - much of which is driven by the fact that our future sea level rise will be largely determined by what happens in the Antarctic.

"Antarctica’s sea ice is changing, and so is a vital part of the marine food web that lives within it"

Antarctica’s sea ice is changing, and so is a vital part of the marine food web that lives within it
When sea ice forms later, the communities of tiny algae that live within it change too. Detecting these early signals now could help us adapt to a changing world.

Next week our ECR group are starting a #MachineLearning sprint to speed up the development of our new #IceSheet surface mass budget emulation models.
I'm looking for hints, ideas tips and inspiration to help smooth and accelerate the process.
If you're used to working in #Sprint mode, what in your opinion makes it work or otherwise hinders it?
What can I as supervisor do to make it run better?
And how should we celebrate it's conclusion?
Also, should me do an #AMA on the process?
