☆ Mucus-Covered Jellyfish Hint at Dangers of Deep-Sea Mining
▼ + stars: | 2023-11-21 | by ( Kate Golembiewski | ) www.nytimes.com time to read: +1 min

Deep-sea mining companies have set their sights on these minerals, aiming to use them in batteries and electronics. Environmentalists warn that the mining process and the plumes of sediment it would dump back into the sea could affect marine life. A series of shipboard experiments on jellyfish in the Norwegian fjords, published Tuesday in the journal Nature Communications, offer insights into those warnings. The scientists approximated the effects of mining by pumping sediment into the jellies’ tanks, essentially asking how the animals would cope with the muddy water. The researchers selected helmet jellyfish as their research subjects because of the ubiquity and hardiness of the dinner-plate-size creatures.

☆ 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."

☆ Medieval monks' observations of the moon reveal unexpected
▼ + stars: | 2023-04-06 | by ( Katie Hunt | ) edition.cnn.com time to read: +5 min

CNN —Medieval observations of the moon are helping present-day researchers study a mysterious cluster of volcanic eruptions on Earth. Monks, and other scribes from the era, made detailed descriptions of lunar eclipses, when the moon is fully in Earth’s shadow. Guillet believes medieval manuscripts contain an important source of information about a string of large but little-understood volcanic eruptions on Earth. These dates correspond with five major volcanic eruptions identified from traces of volcanic ash found in polar ice cores — in 1108, 1171, 1230, 1257 and 1276. “These eruptions were significantly more powerful than some of the most well-known volcanic eruptions in recent history,” Guillet said.

☆ Inside the fierce debate over clean hydrogen, with $100 billion in federal subsidies on the line

The impact of the tax credit on emissions reductions depends on how federal agencies implement it. On one side of the debate, some energy providers say that making the rules too strict could kill the clean hydrogen industry before it ever gets off the ground. CERAWeek returned in-person to Houston celebrating its 40th anniversary with the theme "Pace of Change: Energy, Climate, and Innovation." This hourly approach to energy accounting has been adopted by Google, which has been a forerunner in adopting clean energy, for example. In the long run, Garabedian says, his stance is about protecting his company, the industry's reputation, and the tax credit.

☆ Scientists in Germany turn up heat on seagrass in climate change fight
▼ + stars: | 2022-11-01 | by ( ) www.reuters.com time to read: +2 min

Seagrass stores that carbon "for centuries to millennia", Angela Stevenson, a postdoctoral researcher at the centre, told Reuters. Europe alone lost one third of its seagrass areas between the 1860s and 2016, according to one 2019 study. Seagrass is not a silver bullet for bringing carbon emissions down enough to reach net zero, Stevenson added. Germany has pledged to reduce its greenhouse gas emissions by more than 50% by 2030 compared with the levels in 1990.
