Scientists Warn of 'Scary' Collapse of Ocean Current

Researcher says Atlantic Meridional Overturning Circulation is destabilizing

(Newser) - An ocean current that is effectively the engine that drives weather patterns is in danger, a new study suggests. The Atlantic Meridional Overturning Circulation is a current that moves surface water north from the tropics, warming seawater and adding salt, bringing warm water to the East Coast and Europe, then...

Arctic Sea Ice Is Melting Twice as Fast Now

Cycle of rising temperatures, thinning ice worries researchers

(Newser) - The melting ice in the Arctic is part of a worrisome climate change loop, researchers say. Global temperatures are rising, which causes more Arctic ice to melt, which exposes more dark water to the sun, which raises global temperatures. In fact, the Guardian reports, sea ice in much of the...

EPA's First Climate Update Since 2016 Is Dire

'Americans are seeing and feeling the impacts up close with increasing regularity'

(Newser) - The EPA's website dedicated to climate change indicators wasn't updated once under the Trump administration. Now, it's been given a facelift —and a disturbing one at that. The US is in unprecedented territory with the effects of climate change intensifying even since 2016, according to the...

Brace Yourself: the Arctic Report Card Is Out

It won't look the same in three decades, scientist says

(Newser) - The Arctic sure isn't what it used to be. As temperatures continue to rise, ice melts, snow recedes, and more dramatic changes are on tap for the region, according to the annual NOAA Arctic Report Card released Tuesday. Speaking to reporters, per Scientific American , scientist Rick Thoman called the...

Huge Piece of Ice Cap Splits Off, Worrying Scientists

42-square-mile chunk breaks away in northeastern Arctic

(Newser) - An enormous chunk of Greenland's ice cap has broken off in the far northeastern Arctic, a development that scientists say is evidence of rapid climate change. The glacier section that broke off is 42.3 square miles, the AP reports. It came off of the fjord called Nioghalvfjerdsfjorden, which...

New Study Has Grim News on Polar Bears

They could be almost completely extinct by 2100

(Newser) - Polar bears are likely to be almost completely extinct by the end of this century if climate change continues at its current pace, a new study warns. Scientists already knew polar bears were in deep trouble—they depend on sea ice to survive, and sea ice is disappearing—but researchers...

Container Ship Set for Arctic Marks a 'Turning Point'

Maersk's 'trial' has environmentalists on edge

(Newser) - The world's largest container shipping company will follow explorers who sought sea passages through the Arctic half a millennium ago, though likely with more success thanks to global warming. In what NPR calls a turning point, Denmark-based Maersk will send the first container ship—a 42,000-ton vessel housing...

'Scary' First Hits Arctic's Thickest Ice

Oldest section of sea ice has already shattered 2 times this year

(Newser) - Scientists called it "the last ice area," believing the oldest and thickest section of Arctic sea ice north of Greenland would be the last to remain as our planet warms. Turns out, it's already broken up twice this year, reports the Guardian . More than 13 feet thick...

'We Stood There Crying': Crew Films Starving Polar Bear

Conservation group says it illustrates threat to the bears as ice retreats from Arctic

(Newser) - The video is tough to watch: A crew from the conservation group Sea Legacy came across a starving polar bear in Canada's Baffin Islands that clearly didn't have long to live. "We stood there crying—filming with tears rolling down our cheeks," photographer Paul Nicklen tells...

Tanker Is 1st Ship to Cross Arctic Without Icebreaker

Shrinking ice and new technology helped

(Newser) - For the first time in history, a ship was able to traverse the Northern Sea Route through the Arctic without the help of an accompanying icebreaker thanks to new tanker technology—and climate change. The New York Times reports the Christophe de Margerie, carrying liquefied natural gas from Norway to...

Walruses Show Up Early in Alaska as Ice Recedes

It's the earliest 'haulout' ever

(Newser) - Sign of the times? Several hundred Pacific walruses began amassing on an island off Alaska’s northwest coast in the first week of August in what wildlife officials say is the earliest date yet for their annual "haulout." The culprit appears to be shrinking Arctic ice. Walruses tend...

What May Vanish From the Arctic by 2030

Scientists: There could be no more summer ice by then, thanks to climate change

(Newser) - Fancy an Arctic cruise? With climate change melting the planet's sea ice faster than ever, the globe's northern-most points could become a check on the well-traveled tourist's bucket list. That possibility is giving goose bumps to maritime experts who say safety measures are lacking. "It's...

As Sea Ice Dwindles, Polar Bear Attacks Rise

20% of polar bear attacks happened in last 5 years of 144-year study

(Newser) - There were only 73 reported polar bear attacks on humans between 1870 and 2014, according to a study published this month in Wildlife Society Bulletin . But 20% of those attacks happened in just the last five years of the study, and Alaska Dispatch News reports researchers have found a correlation...

Arctic Ocean Doing Its Best Atlantic Ocean Impression

And that's not great news for sea ice

(Newser) - The "Atlantification" of the Arctic Ocean is underway. And no, that doesn't mean we're about to get the polar bear version of Outkast, but rather that the Arctic Ocean is rapidly becoming more like the Atlantic Ocean, according to new research published Thursday. The Arctic Ocean has...

Scientists Plan to Strand a Ship in Arctic Ice

Polarstern will drift across North Pole so researchers can get info on climate change

(Newser) - The nearly 400-foot-long Polarstern is designed to break through ice in frigid waters—but for an upcoming trip to study climate change, Germany is going to purposely let its ship become stuck in the middle of the floes, per the BBC . In what the Telegraph paints as a "daring...

It's 'Absurdly Warm' in the Arctic Right Now

And sea ice is at its lowest point ever

(Newser) - Experts are calling it "unprecedented," "scary," and "alarming." Wired reports air temperatures in the arctic are currently 20 to 30 degrees above normal. Or in the words of one of those experts: "It's absurdly warm." And that means arctic sea ice—...

Cleaner Air Causing Sea Ice to Melt Away

Sulfur dioxide actually protected ice from the sun: study

(Newser) - Sulfur dioxide is a bad thing, right? Indeed, it's been linked to acid rain, crop failures, and respiratory problems—but scrubbing it from the atmosphere has also apparently caused Arctic sea ice to melt, the Anchorage Daily News reports. According to a new study from Environment Canada, recent reductions...

Researchers Studying Arctic Ice Feared Drowned

Two Dutch scientists encountered thin ice in an unexpected area

(Newser) - Two Dutch researchers are presumed to be drowned while exploring an area of the Arctic where they expected to find thick ice. Marc Cornelissen and Philip de Roo were last heard from on Tuesday, when Cornelissen left a jokey voicemail about how it was so warm near Bathurst Island that...

Polar Bears Will Struggle for Food on Land

Study contradicts research that says bears are eating berries, eggs

(Newser) - Polar bears forced off melting sea ice will not find enough food to replace their current diet of fat-laden seals, researchers say in a conclusion that contradicts studies indicating bears may be benefiting from bird eggs, berries, and other land food sources. Karyn Rode, a USGS wildlife biologist and lead...

Planes Rerouted to Prevent Walrus Stampede

FAA warns media, gawkers to stay away, not spook beached animals

(Newser) - Aircraft, media, and curious folks in general have been instructed to stay far away from the 35,000 walruses crammed onto an Alaskan beach to prevent the easily spooked animals from stampeding each other to death, the Guardian reports. "When they lose their sea ice habitat and come ashore...
