Scientists may have solved the mystery behind a top climate threat

Scientists may have solved the mystery behind a top climate threat

Almost two decades ago, the atmosphere’s levels of methane — a dangerous greenhouse gas that is over 80 times more potent than carbon dioxide in the short term — started to climb. And climb. Then, in 2020, the growth rate nearly doubled.

Scientists were baffled — and concerned. … But now, a study sheds light on what’s driving record methane emissions. The culprits, scientists believe, are microbes — the tiny organisms that live in cows’ stomachs, agricultural fields and wetlands. And that could mean a dangerous feedback loop — in which these emissions cause warming that releases even more greenhouse gases — is already underway.

California gets step closer to building giant new reservoir

California gets step closer to building giant new reservoir

Note: This story is interesting mostly because it relied on a law passed last year that forced state-level judicial processes to move quickly.  The litigation was resolved in less than 6 months.

——
“California needs more water storage, and we have no time to waste — projects like the Sites Reservoir will capture rain and snow runoff to supply millions of homes with clean drinking water,” the governor said in a June 4 news release. “We’re approaching this work with urgency, everything from water storage to clean energy and transportation projects.”

UK to levy a border carbon adjustment on imports by 2027

Britain’s CBAM levies will apply to imports from high-carbon and hard-to-abate sectors including steel and aluminium, cement and ceramics. Additional products may be added to the scope of the CBAM following additional consultations in 2024. The Treasury is set to apply the levy on a sliding scale. Charges applied will depend on the greenhouse gas …

Making hydrogen from waste plastic could pay for itself

Making hydrogen from waste plastic could pay for itself

From Rice University research: “We converted waste plastics ⎯ including mixed waste plastics that don’t have to be sorted by type or washed ⎯ into high-yield hydrogen gas and high-value graphene. If the produced graphene is sold at only 5% of current market value ⎯ a 95% off sale! ⎯ clean hydrogen could be produced for free.” WOW!

melting glaciers methane

Reeling Arctic glaciers leave bubbling methane

Scientists working in one of the world’s fastest-warming places found that rapidly retreating glaciers are triggering the release into the atmosphere of methane, a potent greenhouse gas that causes global temperatures to rise.

The releases are triggered as glaciers across the archipelago of Svalbard, Norway, rapidly retreat and leave behind newly exposed land […]

Reno and Las Vegas Named Among Hottest Cities

Reno and Las Vegas Named Among Hottest Cities

A particularly deadly “heat dome” phenomenon was linked to dozens of deaths across the Pacific Northwest back in 2021, lending fresh urgency to the problem of rising city temperatures.

Zoom in: Average temperature increases from 1970 to 2022 were highest in Reno, Nevada (+11.1°F); Boise, Idaho (+5.8°F); Las Vegas (+5.8°F); Salt Lake City (+5.5°F); and El Paso, Texas (+5.3°F).
