I'm super proud of my @bas.ac.uk colleagues who have worked so hard on this! 👇 🧪🇦🇶❄️🥼

British Antarctic Survey 🐧 @bas.ac.uk · 6d

🧊Our researchers have just finished analysing ancient Antarctic ice spanning 1.2 million years of climate history!

The Beyond EPICA project extends the ice core climate record by 400,000 years, helping us to understand long-term climate patterns and improve future predictions.

In three days, our iconic red planes will take off from Canada to make the epic journey across the world to Antarctica.

These flights mark the start of a new polar science season.

BUT ALSO that means there's three days left to send your name to Antarctica with us! tickettoantarctica.com

We're hiring a GIS and Mapping Specialist to manage our Geospatial Helpdesk and to contribute to our Topographic Map Series.

This is a really exciting opportunity at the British Antarctic Survey to support colleagues across the organisation. Details here: shorturl.at/bA4fd #GISjobs

6 small maps of regions in Antarctica and South Georgia. These are examples of typical Helpdesk outputs from the job being advertised. Each map contains place names, bathymetry in shades of blue, and terrain details on land.

A map of Signy Island, South Orkney Islands. This map is part of our BAS Topographic Map Series. Bathymetry is shown in deepening shades of blue. Details on the land include ice and moraine extent, lakes, contours, and place names.

Heat waves are becoming more dangerous as temperatures and humidity rise.

For healthy adults, the critical threshold for safe activity is lower than previously thought—around 88°F with 60% humidity. Staying hydrated and finding cooling spaces are key as heat risks intensify.

How hot is too hot for the human body? Our lab found heat + humidity gets dangerous faster than many people realize

New research on young, healthy humans found the body begins overheating when exposed to temperatures and humidity lower than previously believed.

Pollen isn’t just an allergen, it’s a natural time capsule preserving Earth’s environmental history for millions of years.

Fossil pollen reveals ancient climates, ecosystems and human impact. Today’s pollen shifts also track #climatechange in real time

Ancient pollen reveals stories about Earth’s history, from the asteroid strike that killed the dinosaurs to the Mayan collapse

Palynologists who study tiny pollen fossils share 4 stories found in grains that fell hundreds to millions of years ago.
