☆ New study warns against risks of ‘time-traveling pathogens’

Through tens of thousands of iterations, the study team tracked how the virus affected species diversity of a bacterial community. About 1% of the ancient viruses caused major disruptions to the digital ecosystems. The pathogen either increased diversity by up to 12% or, conversely, decreased species diversity by 32%. The role of carbon emissionsModern organisms, including humans, have few, if any, natural defense mechanisms for ancient pathogens. If ancient pathogens did somehow manage to escape, they would have trouble finding people to infect.

☆ Oceans absorb 90% of the heat from climate change — here's why record ocean temps are so harmful

"Over 90 percent of the excess energy on earth due to climate change is found in warmer oceans, some of it in surface oceans and some at depth." Put simply, the greenhouse gases serve to trap more heat, some of which is absorbed by the ocean," Kirtman told CNBC. In addition to the daily record on July 31, the monthly sea surface temperature for July was the hottest July on record, "by far," Copernicus said. CopernicusThese record sea surface temperatures arise from multiple factors, including the El Niño weather pattern, which is currently in effect. "These climate variations occur when sea surface temperature patterns of warming and cooling self-reinforce by changing patterns of winds and precipitation that deepen the sea surface temperature changes."

☆ Earth just had its hottest July 'by a long shot,' NASA and NOAA say
▼ + stars: | 2023-08-14 | by ( Denise Chow | ) www.cnbc.com time to read: +4 min

NASA and NOAA together found that last month's average global surface temperature was 2.02 degrees Fahrenheit above the 20th-century average. Last month was also the fourth consecutive month that global ocean surface temperatures hit a record high, the scientists said. This trend in ocean warming carries far-reaching consequences, he said. Changes in ocean temperatures can also have enormous impacts on marine species and their broader ecosystems, he said. This phenomenon is characterized by warm ocean surface temperatures in parts of the Pacific Ocean and tends to boost global temperatures and influence weather conditions around the world.

☆ 2024 will probably be hotter than this year because of El Niño, NASA scientists say
▼ + stars: | 2023-07-20 | by ( Ella Nilsen | ) edition.cnn.com time to read: +3 min

Climate change, caused by burning fossil fuels, is unequivocally warming the Earth’s temperature, NASA scientists said. “It’s really only just emerged, and so what we’re seeing is not really due to that El Niño,” Schmidt told reporters. But, he added, it is likely that a sweltering 2024 will exceed it, precisely because of El Niño’s influence. “We anticipate that 2024 is going to be an even warmer year because we’re going to be starting off with that El Niño event,” Schmidt said. “This issue with ocean temperature is not a problem that stays in the ocean – it affects everything else.” Castillo noted hotter ocean temperatures can make hurricanes stronger and make ocean levels rice due to glacial melt.
