Oregon starts with denser snow and the best near-term accumulation at Mt. Bachelor and Timberline, then the whole Cascade chain turns colder as snow levels fall toward and below pass level during the midweek system.

The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

Snow will reach Tasmania first on Friday night, then spread into Victoria overnight, and finally reach New South Wales resorts on Saturday, tapering off by Sunday evening.

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

Wind chill is a measure of how quickly bodies lose heat when you combine low temperatures with high winds. And wind chill conditions can be dangerous. "The stronger the winds [and] the colder it is, the more likely you are to develop frostbite in a short amount of time or hypothermia," says Jessica Lee of the National Weather Service's Weather Prediction Center.

Such an event, if it transpired on Earth today, would see kilometres-thick ice sheets gouging their way from the Arctic to the Bahamas. Once-diverse ecosystems and climate zones would merge into a single, uniform condition, seemingly destined to be barren. Scientists once argued that such a 'snowball' state could never have existed on Earth since global glaciation could not be reversed. Moreover, on such a world, all life, including our own ancestors, would surely have been extinguished.

He had flown in from Mar-a-Lago and, he told me, was there to observe. The next day, he watched as Åsa Rennermalm, a Rutgers University professor who studies polar regions, sat onstage with European foreign ministers and spoke out against cuts to U.S. science funding. "A leading US Arctic scientist is on stage absolutely ripping her country to the delight of the audience," Dans wrote on X. "Embarassing." He punctuated his post with an American-flag emoji.

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

To get back to average snowpack, we essentially need to have the most snow that we've ever had for the last 30 years between now and mid-April. It would be extremely difficult for Colorado to get back to a normal/average snowpack. As an example, when looking at the Independence Pass SNOTEL site in central Colorado outside of Aspen, we typically have 13 inches of snow-water-equivalent at the end of February. This year, we only have 6.7 inches of SWE.

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.

A bomb cyclone produced freezing temperatures across a large portion of the US from the Gulf coast to New England, bringing heavy snow to North Carolina where two were killed in storm-related conditions, and setting records in Florida, where officials warned of ice and falling iguanas. About 150 million people were under cold weather advisories and extreme cold warnings in the eastern portion of the US,

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.

Many of us are riding the high of the recent major snowstorm wondering when the next big powder day will swing through. Unfortunately for most of North America, it looks like the snowy weather won't be returning anytime soon, or at least not for the next week. Meteorologist Chris Tomer 's Mountain Weather Update paints a rather sad picture for snowfall totals in North America between January 29th and February 5th.
