Heat from El Niño can warm oceans off West Antarctica – and melt floating ice shelves from below

Tue, 2024-04-09 06:11
El Niño can direct more warm water to the base of West Antarctic ice shelves, accelerating melting and increasing global sea level.

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

Tue, 2024-04-09 06:11
Ocean warming seems the main driver of Antarctica’s sea-ice loss. But as satellites show, the change is not universal and sea ice persists in East Antarctica and the Weddell Sea.

The Southern Ocean has the cleanest air on Earth. We have just discovered why

Fri, 2024-04-05 12:04
A lack of human activity in the Southern Ocean is just one reason why the air is so clean. Clouds and rain play a vital role in scrubbing the atmosphere, removing natural airborne particles too.

Why artificial submarine curtains won’t save West Antarctica’s retreating glaciers

Wed, 2024-04-03 10:56
Geoengineering proposals to cool the ocean would indeed reduce ice loss from West Antarctica’s glaciers, but not enough to stop sea-level rise or allow the ice sheet to regrow.

A 20-year ‘mega-drought’ in Australia? Research suggests it’s happened before – and we should expect it again

Wed, 2024-04-03 05:13
Natural variability in Australian rainfall can produce “mega-droughts” lasting 20 years or more. Add in human-caused climate change, and future droughts may be far worse than imagined.

Marine protected areas safeguard more than ecology – they bring economic benefits to fisheries and tourism

Thu, 2024-03-28 15:47
Marine protection represents our best strategy to reverse declining biodiversity. But protected areas also provide a low-tech and cost-effective way for the fishing industry to safeguard stocks.
