The most complete analysis to date measuring ice sheet changes in Antarctica reveals Earth’s southernmost continent has lost some 3 trillion tonnes of ice over the past quarter-century.   A collective effort by over 80 scientists across the world used satellite data to determine estimates of ice-sheet mass balance between 1992 and 2017, ultimately calculating

Every Christmas, sailors from Japan go out into the Southern Ocean, taking “biological sampling” that aims to investigate “the structure and dynamics of the Antarctic marine ecosystem”.   But no, they aren’t trying to understand more about climate change, or investigating the mating songs of the ocean. They’re out killing hundreds of Antarctic minke whales, and

With an eruption like

If you thought the crisis over the gaping hole in the ozone layer was under control, prepare to be disappointed. Researchers at the US National Oceanic and Atmospheric Administration (NOAA) have noticed an unexpected and persistent increase in ozone-destroying chemicals, called chlorofluorocarbons (CFCs).   The Montreal Protocol, which was finalised in 1987, was a revolutionary, international

The ongoing surge in volcanic activity on Hawaii’s Big Island soon could cause a massive explosion from a volcano’s summit, scientists and Hawaii officials warned Wednesday. Kilauea, the longest-erupting volcano on the planet, has displaced some 1,700 people and destroyed 36 structures since a shifting flow of underground magma last week burst through the surface
