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.

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

During this heat wave, "not only are daily temperature records likely to be broken across the region, but even the high temperature records for any day in the entire month of March," the National Weather Service said in a Tuesday morning forecast.

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

Not only will temperatures break March monthly records, but this heatwave will even break April records. Over the next week, around 800 high temperature records are forecast to be neared, tied or broken at 165 locations in Western and Central states - some by more than 10 degrees - with unusual warmth set to linger into late March.

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.

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.

"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."

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

In Berlin, hospitals and clinics and working nonstop to treat a surge of patients with injuries from falling on icy pavements. Surgeons have been working through the night to cope with the influx, with many patients suffering broken bones, concussions and even near-paralysis from falls according to reporting in the Berliner Zeitung. Meanwhile, on Thursday night alone, police in Hanover and the surrounding region recorded 37 traffic accidents due to slippery roads, though thankfully only one person was slightly injured.

Because the past three years have shattered temperature records, researchers have been exploring whether global warming is accelerating, and if so, why. Many scientists agree that the rate at which it is increasing has picked up. This is mainly because of a reduction in air pollution following the introduction of fuel regulations for international shipping (which has resulted in fewer pollutant particles that reflect sunlight into space and seed insulating clouds).

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.

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.

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.

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,

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.
