Frost formation is likely early today in eastern Essex and Union counties, Hudson County and portions of Nassau County, with advisories in effect until 9 a.m. EDT. Most neighborhoods inside the five boroughs should only see patchy frost, but suburban gardens and community plots are more exposed and easier to damage.
Kennedy predicts hot and dry conditions from the west will shift eastward later this week, allowing for a noticeable warm-up and shift towards spring-like conditions.
When scientists applied a new model of human survivability that takes into account the body's ability to function and stay cool depending on age, they found all six events had seen non-survivable periods for older people who could not find shade.
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.
A severe winter storm that brought crippling freezing rain, sleet and snow to a large part of the U.S. in late January 2026 left a mess in states from New Mexico to New England. Hundreds of thousands of people lost power across the South as ice pulled down tree branches and power lines, more than a foot of snow fell in parts of the Midwest and Northeast, and many states faced bitter cold that was expected to linger for days.
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.
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.
Climate change which U.S. President Donald Trump calls the greatest con job ever perpetrated in the world is precisely what is driving the push to gain control of Greenland, an ambition openly declared by Trump. Human-caused global warming is reaching record levels in the Arctic region. This triggers ice melt, opening new shipping routes that major powers want to control, as well as theoretically easier access to the island's resources minerals and fossil fuels.
The reason we can gracefully glide on an ice-skating rink or clumsily slip on an icy sidewalk is that the surface of ice is coated by a thin watery layer. Scientists generally agree that this lubricating, liquidlike layer is what makes ice slippery. They disagree, though, about why the layer forms. Three main theories about the phenomenon have been debated over the past two centuries. Last year, researchers in Germany put forward a fourth hypothesis that they say solves the puzzle.
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.
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.
If you are reading this on the East Coast, congratulations on the warmer weather you're finally getting this week. It was cold and snowy for a while there. Here in the West, we wish we'd been in your shoes. Spare a thought for the tens of millions of us who live on the other side of the continent, where a catastrophe is unfolding.
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.
