We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
At a young age, I learned quickly how oil wealth and power could burn the land while people struggled. I saw heat rise off the streets, the Nile strained, and the air thickened with injustice. In my teenage years, through Aotearoa, being on the edge of the Pacific, I felt the ocean breathing heavy, swallowing the shores of islands that have done the least to cause this harm.
'Our results show that the next 20 years are critical,' lead author Dr Rob Cooke told the Daily Mail. 'By around 2050, we reach a point where the choices we make on emissions and land use will largely determine whether Britain moves towards a much more degraded or a much more nature‑positive future.'
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.
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.
ICE has designs on every major US city. It plans to not only occupy existing government spaces but share hallways and elevator bays with medical offices and small businesses. It will be down the street from daycares and within walking distance of churches and treatment centers. Its enforcement officers and lawyers will have cubicles a modest drive away from giant warehouses that have been tapped to hold thousands of humans that ICE will detain.
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.
That seemingly paradoxical dynamic results from several factors. Foremost among them is the rebound of land beneath the Greenland Ice Sheet, a mile-thick body of glacial ice that covers 80 percent of the island and is being lost to melting at a rate of roughly 200 billion tons each year. As the ice sheet loses mass, the land beneath rises.
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.
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.
In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.
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.
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.
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.
Sea levels are rising faster than at any point in human history, and for every foot that waters rise, 100 million people lose their homes. At current projections, that means about 300 million people will be forced to move in the decades to come, along with the social and political conflict as people migrate inland. Despite this looming crisis, the world still lacks specific, reliable forecasts
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 past 11 years are now the warmest 11 years in the 176-year history of temperature records. What is especially concerning about 2025 is that it occurred during La Niña, a natural Pacific cooling pattern that usually brings lower temperatures. This time, it did not help. Climate scientist James Hansen reports that global warming is now speeding up by 0.31°C per decade, and he predicts we will pass the +1.7°C mark by 2027.
