Polar ice melt driven by climate change is affecting Earth's rotation, according to new research. A human-driven change in the Earth's rotation has never been seen before, and may affect computing. DrPixel/Getty ImagesDon't worry — this change in Earth's rotation won't be catastrophic. Denis Tangney Jr./Getty ImagesAs a result, scientists predict that we would need the first-ever negative leap second by 2026. iStock / Getty Images PlusThere are three main mechanisms that control the Earth's spin:One is tidal friction, or the interaction between moving ocean water and the ocean floor, which slows Earth's rotation.

Clocks may have to skip a second — called a “negative leap second” — around 2029, a study in the journal Nature said Wednesday. “We are headed toward a negative leap second," said Dennis McCarthy, retired director of time for the U.S. Without the effect of melting ice, Earth would need that negative leap second in 2026 instead of 2029, Agnew calculated. In 2012, some computer systems mishandled the leap second, causing problems for Reddit, Linux, Qantas Airlines and others, experts said. Then add in the “weird” effect of subtracting, not adding a leap second, Agnew said.

The happy couple, a pair of sunflower sea stars, belonged to a species that has nearly vanished because of climate change. Sunflower sea stars are a far cry from their smaller pink cousins that you might know from Finding Nemo and SpongeBob SquarePants. “In a perfect, climate-change-free world, they would be keeping the kelp forest ecology at a perfect eco-balance,” Ms. Torres said. As a consequence of the heat, a strange wasting condition began spreading among the sunflower sea star population. Since then, an estimated 90 percent of all sunflower sea stars have perished.

Atmospheric rivers are rivers of water vapors low in the Earth's atmosphere. Below, we answer some FAQs about atmospheric rivers. What causes an atmospheric river? Atmospheric rivers and hurricanes have a few things in common, Cordeira said, but "the processes in the atmosphere that give rise to a hurricane are different than the processes that give rise to atmospheric rivers." In 1994, MIT researchers Yong Zhu and Reginald E. Newell published a paper about "atmospheric rivers and bombs."

LOS ANGELES (AP) — Extreme heat and wildfire smoke are independently harmful to the human body, but together their impact on cardiovascular and respiratory systems is more dangerous and affects some communities more than others. A study published Friday in the journal Science Advances said climate change is increasing the frequency of both hazards, particularly in California. The authors found that the combined harm of extreme heat and inhalation of wildfire smoke increased hospitalizations and disproportionately impacted low-income communities and Latino, Black, Asian and other racially marginalized residents. Homes and work places with air conditioning and neighborhoods with tree canopy cover are better protected from extreme heat, and some buildings filter smoke from wildfires and insulate heat more efficiently. “For a variety of reason, they tend to feel climate change much worse than other non-underserved communities, and I think it's really important to highlight this social injustice aspect of climate change,” said the emergency physician and fellow at the Harvard T.H.

☆ Sonar imagery may have located Amelia Earhart’s long-lost plane, researchers say

Amelia Earhart is photographed with her Lockheed Model 10-E Electra, the aircraft she used in her attempted flight around the world. “While it is possible that this could be a plane and maybe even Amelia’s plane, it is too premature to say that definitively. In Earhart’s last communications, her radio transmissions progressively got stronger as she got closer to Howland Island, indicating that she was nearing the island before she disappeared, Cochrane said. For that reason, you can never say that something is (or isn’t) from a sonar image alone,” Jourdan said in an email. Confirming that the found anomaly is Earhart’s plane would require returning to the site to further investigate the plane, and more definitively, locating the certification “NR16020” that was printed on the underside of the missing Lockheed’s wing, Jourdan said.

The Western United States and Canada are likely to see excessive rain and heavy snowfall from a sequence of back-to-back atmospheric rivers beginning this weekend and continuing into next week. An atmospheric river is like a powerful fire hose with only one person holding it. It could be strong in the San Francisco Bay Area, and little might fall in Southern California, or vice versa. But they are less certain where the heaviest precipitation will fall, especially later in the week. There are at least three atmospheric rivers over the next week, and an additional one beyond that.

WASHINGTON (AP) — Scientists have mapped the largest coral reef deep in the ocean, stretching hundreds of miles off the U.S. Atlantic coast. The largest yet known deep coral reef "has been right under our noses, waiting to be discovered,” said Derek Sowers, an oceanographer at the nonprofit Ocean Exploration Trust. Unlike tropical coral reefs, where photosynthesis is important for growth, coral this far down must filter food particles out of the water for energy. Deep coral reefs provide habitat for sharks, swordfish, sea stars, octopus, shrimp and many other kinds of fish, the scientists said. The world's largest tropical coral reef system, the Great Barrier Reef in Australia, stretches for about 1,430 miles (2,301 kilometers).

At 1,600 meters (5,249 feet) tall, it’s nearly twice the height of Dubai’s Burj Khalifa, the tallest building in the world, according to a news release from Schmidt Ocean Institute, a nonprofit organization that advances oceanographic research. The ship is designed to map the seafloor by using a multibeam echosounder, which sends out sound waves to the ocean floor in a fan-shaped pattern, then measures the time it takes for the sound to reach the ocean floor and return. Schmidt Ocean InstituteThe seamount was discovered 84 nautical miles outside the Guatemalan Exclusive Economic Zone. Watling was not involved with the discovery but was part of a Schmidt Ocean Institute exploration in 2019. The recently discovered seamount may be taller than the world’s tallest building, but some have been found to have a height of 4,000 meters (13,123 feet) or more, Watling said.

☆ A hidden feedback loop under Antarctica’s glaciers could accelerate sea level rise, scientists find
▼ + stars: | 2023-10-27 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +4 min

CNN —Glaciers in East Antarctica could lose ice faster in the future than previously thought, scientists reported Friday, in an alarming feedback loop where glacier meltwater is triggering even more ice loss and sea level rise as the planet warms. Together, these and other recent studies paint a dire picture of a melting southern continent that poses extreme risk of life-altering sea level rise around the world. Friday’s study factored that feedback into simulations to see how much it could accelerate Antarctic melting and sea level rise. Measuring this phenomenon and accounting for it in climate models is necessary “to get a realistic picture of global sea level rise,” Greenbaum said. “Given this evidence, subglacial melt and discharge is a process that can no longer be ignored in future projections of Antarctica’s contribution to sea level rise,” De Rydt told CNN.

☆ Scientists found a new sea creature with 20 'arms' and named it after a strawberry
▼ + stars: | 2023-08-12 | by ( Morgan Mcfall-Johnsen | Lloyd Lee | ) www.businessinsider.com time to read: +4 min

The so-called arms are the longer, feathery-like parts of the Antarctic strawberry feather star shown in the image. It belongs under the class of Crinoidea, which includes starfish, sea urchins, sand dollars, and sea cucumbers, and is a type of feather star — hence the less formal "Antarctic feather star" name. The Antarctic strawberry feather star stands out in particular due to the number of "arms" it has. "So we went from one species with 20 arms to now eight species — six with 20 arms and two with 10 arms under the name Promachocrinus," Rouse said. According to the paper, the Antarctic strawberry feather star was found somewhere between 215 feet to about 3,840 feet below the surface.

Record high levels of carbon pollution in the atmosphere and record low levels of Antarctic ice. Several all-time heat records were also broken earlier this month in Siberia, as temperatures shot up above 100 degrees Fahrenheit. In 2022, the world’s oceans broke heat records for the fourth year in a row. In late February, Antarctic sea ice reached its lowest extent since records began in the 1970s, at 691,000 square miles. The decline in sea ice also poses severe harm to the continent’s species, including penguins who rely on sea ice for feeding and hatching eggs.

☆ Why Does This Cannibalistic Fish Keep Washing Ashore?

For hundreds of years, a strange species of fish with long fanglike teeth that eats its own kind and spends most of its time at the bottom of the ocean has somehow found its way to the shores of the West Coast. The latest appearance by a lancetfish, as the species is known, was on a beach in Oregon, state officials said Monday, prompting more speculation about why the deep-sea creature occasionally surfaces on land. Lancetfish are obscure in part because they have no commercial appeal — meaning that they don’t taste good. The silvery and gelatinous fish have a “scientific name translates to something like scaleless lizard or scaleless dragon,” and they look the part, said Elan Portner, a scientist at the Scripps Institution of Oceanography in San Diego, one place where lancetfish have been found washed ashore. Lancetfish also “migrate as far north as subarctic areas like Alaska’s Bering Sea to feed,” according to the National Oceanic and Atmospheric Administration.

Elephant seals drift downwards in a "sleep spiral" when deep diving in the ocean, a new study found. Sleeping while deep diving allows the seals to avoid predators, scientists believe. The seals fall into sleep during deep dives of up to 377 meters, which is around 1,235 feet, to avoid predators. "This is not light sleep but real paralytic, deep sleep that would have humans snoring. The recordings showed the diving seals going into a sleep stage known as "slow-wave sleep" before transitioning into REM sleep, which leads to a kind of "sleep spiral" or sleep paralysis, experts found.

But some animals get a lot less slumber - with certain species like the northern elephant seal taking sleeplessness to an extreme. During dives lasting about 30 minutes, the seals went into a deep sleep stage called slow-wave sleep while maintaining a controlled downward trajectory. The species is the world's second-largest seal, topped only by the southern elephant seal. Male northern elephant seals may reach 13 feet long (4 meters) and weigh up to 4,500 pounds (2,000 kg).

The researchers refer to this as a “sleep spiral.”The research marked the first time scientists recorded brain activity in free-ranging wild marine mammals, capturing data from 104 sleep dives. Then she attached them to 13 juvenile female elephant seals that are part of a colony at Año Nuevo State Park in Pescadero, California. In shallow waters, the elephant seals even reached the seafloor, where they would rest. During REM sleep, elephant seals enter a "sleep spiral." Elephant seals sleep the most along the coast and near their foraging grounds, and that data could be used to see how shipping traffic could affect the seals.

☆ California has been hammered with rain. It may not be enough to reverse its drought.

California counts on a system of about 1,400 human-made surface reservoirs and thousands upon thousands of miles of levees to manage surface water. During the recent storms, extreme drought has buffered some impacts of intense rainfall with plenty of space in the state’s largest reservoirs, which have withered under drought. Before the series of atmospheric rivers, it was storing less than 1 million acre-feet of water. In the Central Valley, Californians extract about 2 million acre-feet more than what returns to the ground, on average, every year, Lund said. California legislators in 2014 passed the Sustainable Groundwater Management Act, which requires local agencies to reach groundwater sustainability by 2042.
