An analysis of sediments from five North Carolina lakes near coal-burning power plants has found that coal ash pollution of surface waters has been more persistent and widespread than was previously known.

Subtropical gyres are enormous rotating ocean currents that generate sustained circulations in the Earth’s subtropical regions just to the north and south of the equator.

Forecasters are predicting a “three-peat La Niña” this year.

The new method could be used to cut greenhouse gas emissions and reduce reliance on nondegradable plastics.

Scientists from the University of Illinois Urbana-Champaign, University of California, Santa Barbara, and Dow have developed a breakthrough process to transform the most widely produced plastic — polyethylene (PE) — into the second-most widely produced plastic, polypropylene (PP), which could reduce greenhouse gas emissions (GHG).

Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is responsible for providing carbon for almost all life on Earth.

A team of scientists, led by Professor Adam Scaife from the University of Exeter, has used state-of-the-art mathematical modelling to show how fluctuations in the length of the day can be predicted more than a year in advance – significantly longer than currently possible.

Rising sea levels from melting glaciers and ice sheets pose an increasing threat to coastal communities worldwide. 

Developing countries should focus on keeping unnecessary occupants, such as children, out of kitchens during cooking to help reduce their exposure to dangerous levels of air pollution, recommends a study by the University of Surrey.   

Marine heatwaves brought about by climate change are known to be responsible for mass mortality on some of the planet’s most iconic coral reef systems.
