Climate Change Is Accelerating Faster Than We Can Respond, Scientists Warn - Time Magazine

The climate is warming up faster than we can respond. According to a new report published Oct. 14 in the journal BioScience, "Earth's climate system is moving deeper into uncharted territory. "The State of the Climate, an annual report that tracks the Earth's "vital signs," monitors several climate related indicators—ranging from greenhouse gas concentrations and temperature changes to tree cover loss due to wildfire. The researchers found that, of the 16 planetary vital signs, seven are currently at record extremes. This includes sea levels and greenhouse gasses in the atmosphere. Meanwhile several others, such as areas burned during wildfires and ocean heat levels, show evidence of acceleration or abrupt shifts. The researchers warn that the rate of global warming appears to have accelerated, from about 0.05°C per decade between 1880 and 1970 to roughly 0.36°C per decade between 2010 and 2024—and the 2°C threshold meant to limit planetary damage could be reached before 2050 they warn.

Milky Way’s first microblazar candidate sits 12,000 light-years away, offering a rare ground-level lab for studying relativistic jetsA black hole 12,000 light-years away is firing a jet of plasma almost directly toward Earth. At that distance, no known or expected danger to Earth has been identified by the researchers or the institutions involved. What astronomers have actually found is rarer and more interesting than a threat. Researchers have identified IRAS 18293-0941 as a compelling candidate for the Milky Way’s first microblazar, a class of object that gives astrophysicists a close-up laboratory for studying some of the most violent physics in the galaxy. What Astronomers FoundThe discovery centers on a binary system whose black hole expels plasma jets at close to three-quarters the speed of light, pointed almost directly toward Earth. The system pairs a hot, massive star with a black hole that completes a full orbit roughly every 11.38 days. Material drawn from the companion star feeds the black hole, and some of that matter gets expelled outward as opposing jets traveling at approximately three-quarters the speed of light. Terminology matters here.

Forests that stood on Mozambique's coast thousands of years ago now lie beneath shallow seas, and they have become fish-filled "peat reefs" with marine life comparable to coral reefs, researchers report in Scientific Reports. A team from the Bazaruto Center for Scientific Studies (BCSS) Ocean Observatory, led by Mario Lebrato, documented the submerged peat in the Bazaruto Archipelago in the Western Indian Ocean. BCSS, founded in 2017, describes itself as Africa's first permanent ocean observatory. Working with universities and institutions in the U. K., U. S. and Canada, the team believes it has carried out the first ecological study of peat reefs anywhere in the tropics. Old forests, new seafloorRadiocarbon dating shows the peat formed between about 300 and 5,000 years ago, and chemical analysis indicates it came mostly from coastal land plants and trees. Some samples contain up to 40% organic carbon by dry weight. Lebrato said the coastline has very little natural hard seabed, mostly shifting sand. As rising seas expose the old peat layers, they create rare solid habitat where marine life can settle, hide and feed.
