Climate is most important factor in where mammals choose to live, study finds      (via sciencedaily.com)     Original source 

Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.

Climate change will bring more turbulence to flights in the Northern Hemisphere, study finds      (via sciencedaily.com)     Original source 

A type of invisible, unpredictable air turbulence is expected to occur more frequently in the Northern Hemisphere as the climate warms. Known as clear air turbulence, the phenomenon also increased in the Northern Hemisphere between 1980 and 2021.

Great Salt Lake a significant source of greenhouse gas emissions      (via sciencedaily.com)     Original source 

Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.

Waters along Bar Harbor, Acadia home to billions of microplastics      (via sciencedaily.com)     Original source 

Researchers reveal there are an estimated 400 billion microplastic fibers on the surface of Frenchman Bay, which borders Bar Harbor and Acadia National Park in Maine, and several connected rivers and estuaries where freshwater from rivers meet salty seawater. The watershed contains an average of 1.8 fibers per liter of water. The team also investigated how microplastics traveled throughout the watershed by sampling water from nine sites on Mount Desert Island, particularly within Bar Harbor.

Southern Ocean absorbing more carbon dioxide than previously thought, study finds      (via sciencedaily.com)     Original source 

New research has found that the Southern Ocean absorbs more carbon dioxide (CO2) than previously thought. Using direct measurements of CO2 exchange, or fluxes, between the air and sea, the scientists found the ocean around Antarctica absorbs 25% more CO2 than previous indirect estimates based on shipboard data have suggested.

How well does tree planting work in climate change fight? It depends      (via sciencedaily.com)     Original source 

Using trees as a cost-effective tool against climate change is more complicated than simply planting large numbers of them, an international collaboration has shown.

Researchers warn of unprecedented arsenic release from wildfires      (via sciencedaily.com)     Original source 

The wildfire season of 2023 was the most destructive ever recorded in Canada and a new study suggests the impact was unprecedented. It found that four of the year's wildfires in mine-impacted areas around Yellowknife, Northwest Territories potentially contributed up to half of the arsenic that wildfires emit globally each year.

Hot traces in rock      (via sciencedaily.com)     Original source 

Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive. Researchers have used 380-million-year-old limestones from Hagen-Hohenlimburg to show in detail which climate information is still preserved in the rock.

Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development      (via sciencedaily.com)     Original source 

Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.

Deep-ocean floor produces its own oxygen      (via sciencedaily.com)     Original source 

An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.

Sea ice's cooling power is waning faster than its area of extent      (via sciencedaily.com)     Original source 

As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research.
