Antarctica’s sea ice hit another low this year— understanding how ocean warming is driving the loss is key

At the end of the southern summer, Antarctica’s sea ice hit its annual minimum. By at least one measure, which tracks the area of ocean that contains at least 15 per cent of sea ice, it was a little above the record low of 2023.

The next pandemic? It’s already here for Earth’s wildlife

'I am a conservation biologist who studies emerging infectious diseases. When people ask me what I think the next pandemic will be I often say that we are in the midst of one, it’s just afflicting a great many species more than ours. I am referring to the highly pathogenic strain of avian influenza H5N1 (HPAI H5N1), otherwise known as bird flu' the author writes.

World's largest iceberg breaks free, heads toward Southern Ocean

Recent satellite images reveal that the berg, weighing nearly a trillion metric tonnes, is now drifting quickly past the northern tip of the Antarctic Peninsula, aided by strong winds and currents.

Subglacial meltwater flowing beneath Antarctic glaciers could accelerate retreat, study finds

The findings, relevant in a high emissions scenario featuring 20 per cent higher CO2 emissions by 2100, suggested that the subglacial discharge's influence was large enough to make a meaningful contribution to global sea-level rise, the researchers at the University of California San Diego's Scripps Institution of Oceanography in the US said.

Rapid Antarctic melting looks certain, even if emissions goals are met

As the planet warms, larger volumes of warm water are bathing the undersides of West Antarctica’s ice shelves, the giant tongues of ice at the ends of glaciers.

As Antarctic sea ice continues its dramatic decline, we need more measurements and much better models to predict its future

Some scientists have suggested this year could mark a regime shift for Antarctic sea ice. The consequences could be far-reaching for Earth’s climate, because sea ice keeps the planet cooler by reflecting solar energy back into the atmosphere and insulating the ocean. Its formation also generates cold, salty water masses that drive global ocean currents.
