Fighting climate change with venture capital is different this time – Axios

Silicon Valley got a black eye a decade ago when its big venture capital foray into expensive and nascent cleantech didn’t pan out—but its recently renewed interest in a wider scope of technologies that can tackle the climate crisis could…

Warming homogenizes apparent temperature sensitivity of ecosystem respiration – Science Advances

INTRODUCTION Terrestrial ecosystem respiration (Re), the sum of autotrophic respiration from primary producers and heterotrophic respiration from consumers and detritivores, represents a fundamental biospheric function and plays a major role in the global carbon cycle and growth rate of atmospheric…

Ocean eddies strongly affect global mean sea-level projections – Science Advances

INTRODUCTION Satellite-observed sea-level measurements indicate an ongoing increase in the global mean sea level since the satellite era (1–3). Global mean sea-level rise (GMSLR) threatens low-lying coastal regions, and these regions will benefit strongly from sea-level projections to adapt their…

Abrupt ice age climate changes behaved like cascading dominoes

(University of Copenhagen – Faculty of Science) Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the climate system changed, other parts of the climate system followed like a series of dominos toppling in succession. Today, sea-ice extent is being rapidly reduced, and it is uncertain whether this part of the climate system can trigger sudden future climate change.

X-ray study recasts role of battery material from cathode to catalyst

(DOE/Lawrence Berkeley National Laboratory) An international team working at Berkeley Lab used a unique X-ray instrument to learn new things about lithium-rich battery materials that have been the subject of much study for their potential to extend the range of electric vehicles and the operation of electronic devices.

Could climate change spell the end of Colombian coffee? – Euronews

Colombia might be the world’s third-largest coffee producer, but the climate crisis is causing new challenges for its growers. In a new study, scientists have used models to predict how climate change will affect coffee growers in the South American…

Schild receives NASA NIP award to develop new predictive tool for iceberg melting speeds

(University of Maine) Research led by University of Maine glaciologist Kristin Schild to quantify and predict iceberg melting rates has received NASA New (Early Career) Investigator Program (NIP) in Earth Science funding. Schild will develop universal measuring strategies and a model for predicting how fast any iceberg would melt and discharge freshwater into the ocean. These tools could and enhance how global-scale models forecast sea level rise and climate change as a result of glacial ice activity.

Regional habitat differences identified for threatened piping plovers on Atlantic coast

(US Geological Survey) Piping plovers, charismatic shorebirds that nest and feed on many Atlantic Coast beaches, rely on different kinds of coastal habitats in different regions along the Atlantic Coast, according to a new study by the U.S. Geological Survey and U.S. Fish and Wildlife Service.

Global Telescope Creates Exquisite Map of Black Hole’s Swirling Magnetic Field

A new view of the region closest to the supermassive black hole at the center of the galaxy has shown important details of the magnetic fields close to it—and hints about how powerful jets of material can originate in that region. A worldwide team of astronomers using the Event Horizon Telescope (EHT) measured a signature […]
