Hello! 👋

We're the UK's polar research institute. We do climate and ecosystems science in Earth's frozen places, because changes there affect all of us.

As we say at British Antarctic Survey: what happens in Antarctica doesn't stay in Antarctica ⬇️

Under current climate policies, 79 per cent of the world’s glaciers will disappear by 2100, endangering the water supply for 2 billion people and raising sea levels dramatically
The world will soon be losing 3000 glaciers every year

The NBP has finished her last USAP cruise. Not the outcome we’ve been hoping to see. I’m of course glad that researchers are being supported by substitute vessels. But, it’s not clear how this will work in the long run.

How the myth of ‘aqua nullius’ still guides Australia’s approach to groundwater
For too long, Indigenous perspectives have not been heard in groundwater science. We must work together to protect Australia’s precious groundwater.

Exploring Drip Water Dynamics for Groundwater Recharge
The end of the year is approaching, and the papers and pre-prints are still coming from the groundwater and climate research team here and our collaborators. Here is a summary of our outputs the last three months of the year. All are open-access, with links provided below Most recently, my photo made the cover of the Eos Buzz Newsletter, where Stacey Priestley (CSIRO) led this article with myself, Wendy Timms (Deakin), Margaret Shanafield (Flinders) and Martin Andersen (UNSW).

Evidence of rapid glacial-deglacial switching, from a high resolution record from #Pliocene marine sediments, foretells #WestAntarctica 's future theconversation.com/west-antarct...

#Geologists can't help get enthused about "real time" processes: regional events that happen swiftly, as opposed to long, slow, gradual change per #Hutton 's Principle of #Uniformitarianism. Take, for example, 🇦🇶 #WestAntarctica 🇦🇶 in the #Pliocene:
West Antarctica’s history of rapid melting foretells sudden shifts in continent’s ‘catastrophic’ geology
A picture of what West Antarctica looked like when its ice sheet melted in the past can offer insight into the continent’s future as the climate warms.

Drilling a 200m sediment core from the bedrock beneath 500m of Antarctic ice is a complex process, so we've broken it down step-by-step in this explainer. From melting snow in our flubbers through to filling our core barrels, what we're attempting 700km from the nearest base is no mean feat!

Have you ever seen a green flash on the setting #sun? A sunset walk on a west-facing beach is a great time to see a green flash. This phenomenon happens when the sun is almost entirely below the horizon, with the upper edge still visible. It's brief but exciting! ☀️🔭

Despite #NCAR's commitment and service to ALL Americans due to their role in US weather forecasting and longterm records. It will be archaic and debilitating to destroy this well-tuned, society-serving government agency and its functions can't be transferred nor rebuilt readily.
