Scientists expose vulnerabilities of critical Antarctic ice shelf

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to complete…

Major sea-level rise is ‘now inevitable’

Major sea-level rise from the melting of the Greenland ice cap is now inevitable, scientists have found, even if the fossil fuel burning that is…

World’s biggest ice sheet could cause massive sea rise without action

The world’s biggest ice sheet could cause “several meters” of sea-level rise over centuries if the global temperature rises more than 2°C, according to a…

Ice shelves hold back Antarctica’s glaciers from adding to sea levels, but they’re crumbling

As Antarctica’s slow rivers of ice hit the sea, they float, forming ice shelves. These shelves extend the glaciers into the ocean until they calve…

Troubling new research about East Antarctica

The eastern two thirds of Antarctica is covered by an ice sheet so large that if it melted the sea would rise by 52 meters…

Antarctic is changing dramatically, with global consequences

Antarctic ice sheets are melting, the continent’s climate is changing, and the Southern Ocean is warming, becoming more acidic and losing oxygen. Locally, changing climates…

First evidence of microplastics in Antarctic snow

Most people see Antarctica as a pristine, relatively untouched place, but a new study published today has revealed the presence of microplastics – plastic pieces…

It’s 70˚F (40˚C) warmer than normal in eastern Antarctica. Scientists are flabbergasted.

The coldest location on the planet has experienced an episode of warm weather this week unlike any ever observed, with temperatures over the eastern Antarctic…

Each Antarctic tourist effectively melts 83 metric tons of snow

The remote continent is becoming increasingly accessible—during the 2019-20 season, the number of sightseeing visitors reached 74,000, with the vast majority travelling by ship. All…

Study – Rapid glacier retreat rates observed in West Antarctica

The Pope, Smith and Kohler glaciers, in the Amundsen Sea Embayment of West Antarctica, have experienced enhanced ocean-induced ice-shelf melt, glacier acceleration, ice thinning and…

Scientist says time is running out for West Antarctic ice sheet

The last time carbon dioxide levels were where they are today, at more than 415 parts per million, was 4 million years ago, and the…

Butressing of Thwaites glacier in Antarctica expected to fail within 10 years

Scientists have discovered a series of worrying weaknesses in the ice shelf holding back one of Antarctica’s most dangerous glaciers, suggesting that this important buttress…

Antarctic ice sheet destabilized within a decade

After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern…
