The fate of the planet’s coastlines depends on how fast Antarctica’s ice sheets melt. We don’t know what’s coming

Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences

On one side of Dr Ben Galton-Fenzi’s view across the vast Totten ice shelf, the sun sat low on the Antarctic horizon. On the other, a full moon.

The ice shelf is “flat and white”, says Galton-Fenzi. “If there’s cloud around, you lose the horizon.”

Even as administration officials vowed this week to head off scheduled retirements, some aging plants are now breaking, and costs could run to the billions.

A coal-burning unit at the Craig Generating Station had been set to close since 2016, but the Energy Department has ordered that it stay open.

Data leads scientists to declare 2015 Paris agreement to keep global heating below 1.5C ‘dead in the water’

Last year was the third hottest on record, scientists have said, with mounting fossil fuel pollution behind “exceptional” temperatures.

The World Meteorological Organization (WMO) said 2025 had continued a three-year streak of “extraordinary global temperatures” during which surface air temperatures averaged 1.48C above preindustrial levels.

Study from research firm finds that US greenhouse gas emissions grew faster than economic activity last year

In a reversal from previous years’ pollution reductions, the United States spewed 2.4% more heat-trapping gases from the burning of fossil fuels in 2025 than in the year before, researchers calculated in a study released on Tuesday.

The increase in greenhouse gas emissions is attributable to a combination of a cool winter, the explosive growth of datacenters and cryptocurrency mining, and higher natural gas prices, according to the Rhodium Group, an independent research firm. Environmental policy rollbacks by Donald Trump’s administration were not significant factors in the increase because they were only put in place this year, the study authors said. Heat-trapping gases from the burning of coal, oil and natural gas are the major cause of worsening global warming, scientists say.
