Antarctica sees similar climate change effects as Greenland: Study
The planet's warming climate is having effects in Antarctica that increasingly resemble those observed in the Arctic, meaning global sea levels could rise faster than previously predicted, Danish researchers warned on Friday.

The first session of the second #AntarcticaInSync webinar is about to start - an international effort to coordinate research on and around the southern continent. Come and talk to me about land based observations and climate variability ... https://www.antarctica-insync.org/2nd-antarctica-insync-international-science-webinar/

🚨 New preprint out🚨 now, why has Antarctica stopped (net) losing mass?
We explore how declining sea ice but mostly increasingly heavy and frequent atmospheric rivers have actually led to a small increase in the mass of #Antarctica, in spite of increased discharge from outlet glaciers.
The increase is unlikely to be sustained, and a small increase in calving or discharge over the grounding line can easily turn it upside down, but nevertheless another long-term prediction about the Antarctic appears to becoming true.
Lots of important subtleties in this one!
In review at Nature communications but I feel it's too important to wait for the review process.

Air temperatures over Antarctica have soared 35ºC above average. What does this unusual event mean for Australia?
The stratospheric polar vortex high above Antarctica has rapidly heated up. These sudden bursts of heat can bring rapid weather changes in Australia

Meeting LISA
LISA: the Lightweight In Situ Analysis box is one of a kind, built by our friends at PICE in the Niels Bohr Institute. Later this year we're taking LISA to #Antarctica for the first time ever, to analyse shallow #snow and #firn cores directly in the field. We hope LISA will help us understand how much snow falls in Dronning Maud Land, how much it varies from year to year and what is the influence of sea ice and far field atmospheric processes on the rate…

"Rising visitor numbers are leaving a harmful human footprint on Antarctica’s ecosystems"
#Antarctica #Climate #ClimateChange

Surging tourism is polluting Antarctica, scientists warn
Annual visitors numbered fewer than 8,000 in the 1990s. Last year, more than 124,000 visited.

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.

"Penguin Guano in Antarctica May Help Cool the Planet"
#Antarctica #Penguins #Climate #ClimateChange

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.

Ever heard of #AntarcticaInSync? It's a very cool initiative to better understand the Southern Ocean and it's icy continent..
Kicking off the second webinar now..

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?
