The ongoing Sunday night into Monday storm across the central Andes keeps producing mainly upper-mountain snow through Monday before tapering out by Tuesday morning, April 21. A realistic near-term outcome is about 16-20 cm at Las Leñas, 9-11 cm at Valle Nevado, and lighter 5-8 cm amounts around El Colorado, La Parva, and Portillo.

The voyage of the crew in a 22.5-foot ship's boat through the 'Furious Fifties' is regarded by many historians as the greatest small-boat journey ever completed.

'Forever' chemicals, which do not break down in the environment, have been detected in Antarctica, highlighting their widespread presence even in remote areas.

Travelling there was a childhood dream of mine. I saw it as a way to test myself against something so much bigger. I nearly applied for a role at the British Antarctic Survey (BAS) 30 years ago, but then my wife and I were expecting our first child. Instead, I've worked as a chef in Michelin-star restaurants in Paris and London, hotels in Kuala Lumpur and St Moritz, and even at a school in Oxfordshire.

Imagine waking up on a ship surrounded by icebergs, camping in the snowy wilderness and kayaking among the exhalations of humpback whales. You can also take part in a polar plunge, board small zodiac boats to search for leopard seals and collect samples for science research.

When a city or country is in the spotlight, it's logical to expect an uptick of interest in visiting there. Each of the locations where a season of The White Lotus was filmed has seen a corresponding increase in tourism, for instance. Being the subject of news headlines and heated negotiations isn't quite the same thing as being the setting for a prestige TV series, but recent data suggests that Greenland is also seeing more international visitors than usual.

Changes in the Antarctic do not stay in the Antarctic. Though Antarctica is far away, changes here will impact the rest of the world through changes in sea level, oceanic and atmospheric connections and circulation changes.

Greenland is currently making headlines, much to the chagrin of Greenlanders. U.S. President Donald Trump's ambition to seize this island, an autonomous territory of Denmark, a NATO founding member, has turned global attention to a corner of the planet they probably hadn't considered before, or to Wikipedia or AI tools, to find out who lives on that enormous white patch in a corner of the American continent, and how.

'They save up ice like a savings account and then spend it all very quickly like a Black Friday event.'

Recently, Anchorage, Alaska's largest city with nearly 400,000 residents, has just recorded its snowiest January on record. Tucked in between the mighty Cook Inlet and pushed right up against the Chugach Mountains, Anchorage sits in prime location for some serious snow totals. Moisture from pacific storms builds up over the inlet, and thanks to orographic lift caused by the mountains, forces that moisture to drop over Anchorage. Thanks to Alaska's northernly location, that moisture often falls in the form of snow.

Decades of successful scientific collaboration could be at risk if Europe-US political relations continue to fray over trade and defense issues. For more than 30 years, Arctic nations have worked together across the physical, biological and social sciences to understand one of the world's fastest changing regions. Since the late 1970s, the Arctic has lost around 33,000 square miles of sea ice each year roughly the same area as Czechia.

Polar bears are the poster children of climate changeand for good reason. These giant bears hunt, mate and spend their days hanging out on Arctic sea ice, which is rapidly disappearing as the climate warms. But some polar bears, it seems, are far more resilient than we realized: new research suggests that in one region, the bears are adapting to the declining sea ice.

The Northeast Passage was expected to open first due to the Coriolis effect. As the world turns to the east, in the Northern hemisphere, flowing water will veer to the right. Warm, salty Atlantic water flows into the Arctic Ocean through the Barents Sea Opening between Norway and Svalbard, and the Fram Strait between Svalbard and Greenland, then bends right along the Arctic coasts of Norway and Russia.

At first glance, it looked like Wooller and his colleagues might have found evidence that mammoths lived in central Alaska just 2,000 years ago. But ancient DNA revealed that two "mammoth" bones actually belonged to a North Pacific right whale and a minke whale-which raised a whole new set of questions. The team's hunt for Alaska's last mammoth had turned into an epic case of mistaken identity, starring two whale species and a mid-century fossil hunter.

Ice-sheet retreat lined up with low algae growth over the past ~500,000 years, implying less CO₂ uptake in parts of the Southern Ocean during warm periods. The study points to iceberg-delivered, iron-rich sediments from West Antarctica during warm intervals, not windblown dust. The iron-bearing minerals in these sediments were highly weathered and not readily bioavailable to marine algae. If WAIS keeps shrinking, similar sediment delivery could weaken Southern Ocean carbon uptake, creating feedback that could amplify climate change.

The vast gravity hole, known as the Antarctic Geoid Low (AGL), is the product of incredibly slow rock movements, according to the experts. Starting 70 million years ago - a time while dinosaurs still roamed the Earth - less-dense rock built up beneath the frozen continent and weakened the pull of gravity. The gravity hole started small before rapidly growing in strength between 50 and 30 million years ago - creating the strange ocean dip that we see today.
