Australia Transport Authority Won’t Approve Tesla’s Battery-Powered Semi

Did you know that TESLA also manufactures an e-truck? But Australia has refused to approve the “Semi”. We recently reported on the Nikola company’s hydrogen truck. Engineers and other experts have doubts about the concept because the extremely volatile gas…

Catastrophic sea-level rise from Antarctic melting possible with severe global warming – EurekAlert

The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers…

Map of Milky Way halo reveals dark matter ocean

The gravity of the Large Magellanic Cloud – one of the Milky Way’s satellite dwarf galaxies – is collecting stars behind it in a trail, like the wake from a boat, as it travels through our galaxy’s halo.

Strange isotopes: Scientists explain a methane isotope paradox of the seafloor

(Max Planck Institute for Marine Microbiology) Deep down in the seafloor anaerobic microbes consume large amounts of methane, a potent greenhouse gas. Even though this process is a crucial element of the global carbon cycle, it is still poorly understood. Scientists from Bremen and Israel now found the solution to a long-standing enigma in this process: why methane carbon isotopes behave so differently than expected. In a joint effort with their colleagues they present the answer in the journal Science Advances.

New GSA Bulletin articles published ahead of print in April

(Geological Society of America) The Geological Society of America regularly publishes articles online ahead of print. For April, GSA Bulletin topics include multiple articles about the dynamics of China and Tibet; the Bell River hypothesis that proposes that an ancestral, transcontinental river occupied much of northern North America during the Cenozoic Era; new findings in the climatic history during one of Earth’s coldest periods: The Late Paleozoic Ice Age; and the age an nature of the Chicxulub impact crater.

Changing specialisation to cope with climate change | VOX, CEPR Policy Portal – voxeu.org

Bruno Conte, Klaus Desmet, Dávid Krisztián Nagy, Esteban Rossi-Hansberg 04 May 2021 In discussing trade policy in the context of climate change, some people are quick to argue that trade might have to be restricted. After all, trade involves transportation,…

Debunked: New Computer-Simulated Pine Island Glacier Doomsday Paper Ignores Science

A recent paper announcing Pine Island Glacier doom failed to consider other findings showing the glacier is in fact more stable than assumed. A new paper by Rosier et al concludes – based on model simulations – that the Pine…

New Smart Farming Robot Unveiled That ‘Smokes’ Weeds With High-Powered Lasers For Healthy Weeding

Weeds compete for soil nutrients, water, space, and sunlight with the crops farmers grow to help feed people. Now a third-generation weeding robot, armed with lasers and powered by AI, offers the ultimate labor-saving device—while also eliminating the need for chemical herbicides. The Autonomous Weeder by Carbon Robotics can eliminate 100,000 weeds per hour, and […]

Empowering citizens for successful energy transitions

(International Institute for Applied Systems Analysis) The terms “co-creation” and “co-production”, which denote the possibility for laypeople to participate in decision-making processes that affect their lives, have been gaining popularity. A new IIASA-led study explored options for empowering citizens as a driver for moving from awareness about the need to transform energy systems to action and participation.
