Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution      (via sciencedaily.com)     Original source 

An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.

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.

Images of nearest 'super-Jupiter' open a new window to exoplanet research      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.
