Right now, every moment of every day, we humans are reconfiguring Earth’s climate bit by bit. Hotter summers and wetter storms. Higher seas and fiercer wildfires. The steady, upward turn of the dial on a host of threats to our homes, our societies and the environment around us. We might also be changing the climate […] More
Rising temperatures in Antarctica are making meteorites sink out of view before researchers can collect them.If you’re looking for meteorites, here’s a tip: Go south. All the way south. And do it soon.In some parts of Antarctica, there’s a good chance that what looks like a regular old rock could actually be a chunk of an asteroid, the moon, or even Mars. Roughly 60 percent of all known meteorites have been collected there.But scientific sleuthing for such extraterrestrial material, which can shed light on how the solar system formed billions of years ago, will probably get more difficult in Antarctica in the coming decades. That’s because, as temperatures rise, thousands of meteorites will sink into the continent’s ice and disappear from sight every year, according to a new study published on Monday.Antarctica’s meteorite largess isn’t because more extraterrestrial stuff is falling there, Cari Corrigan, a geologist at the Smithsonian Institution and a curator of the National Museum of Natural History’s meteorite collection, said.Rather, meteorites simply tend to be more visible on the Antarctic ice sheet than they would be, say, in your backyard. “Your eye can pick out a dark rock on a white surface super easily,” said Dr. Corrigan, who was not involved in the new research.The continent also has places known as blue-ice areas, that are particularly good for finding meteorites. These regions are often near geographic obstructions like mountains, where layers of ice tend to pile up and strong winds continuously erode the surface. Those conditions are ideal for concentrating, and revealing, meteorites that have fallen over millenniums.But warming temperatures could send many meteorites out of sight. In recent years, researchers have spotted specimens in Antarctica that have been partially encrusted in ice rather than sitting exposed on the surface.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Plus the Olympics end and Queen Elizabeth II tests positive.Mortar attacks continued through the weekend in eastern Ukraine.Tyler Hicks/The New York TimesRussia’s imminent invasion?U.S. intelligence learned last week that the Kremlin had ordered an invasion of Ukraine to proceed, prompting a dire warning by President Biden that President Vladimir Putin had made the decision to attack.The new intelligence reveals that 40 to 50 percent of the Russian forces surrounding Ukraine have moved out of staging and into combat formation.Russian artillery fire escalated sharply in eastern Ukraine this weekend, deepening fears of an imminent attack and potentially giving Russia a pretext to invade. Ukrainians reluctantly left their homes, some evacuating to Russia. After repeated assurances that military drills would end this weekend, Belarus said that it and Russia would continue to “test” their military capabilities and that Russian troops would stay longer than planned. NATO has long warned that the deployment could be used as cover to build an invasion force.Resources: Here are live updates, an explainer about the conflict and a timeline.Genocide: The single word has become key to Moscow’s baseless accusations against the Ukrainian government — and a wider quest for a new imperial identity rooted in Russian ethnicity.Ukraine: The conflict has weakened Ukraine’s economy, but its people are doubling down. Paramilitary groups are preparing for an invasion.Diplomacy: President Volodymyr Zelensky left Ukraine to meet with leaders in Europe. Zelensky urged sanctions against Russia and criticized the Western response after the U.S. heightened its warnings of an imminent Russian attack.

Some Chinese Americans see themselves in the duality she has embraced.Pandemic: China’s “closed loop” approach worked — and birthed new infrastructure. Only a few athletes had to miss their competitions, and there were days when not a single test came back positive.Business: Olympic sponsors are struggling to straddle a widening political gulf between the U.S. and China: What is good for business in one country is increasingly a liability in the other.If Queen Elizabeth II is too ill to fulfill her duties, her heirs — Prince Charles and Prince William — would step in to lead.Steve Parsons/Agence France-Presse, via Pool/Afp Via Getty ImagesQueen Elizabeth tests positive for Covid The 95-year-old British monarch was “experiencing mild coldlike symptoms,” Buckingham Palace said.Although the circumstances of the queen’s infection remained clouded in questions, Prince Charles, her eldest son and heir, tested positive in a breakthrough infection two days after meeting with her earlier this month.After canceling public events in the fall, citing exhaustion, the queen has begun appearing in public again.
