Huge swaths of North America are facing subfreezing temperatures this week as cold Arctic air pushes southward. 

2024 was another year of record-breaking temperatures, driving the global water cycle to new climate extremes and contributing to ferocious floods and crippling droughts, a new report led by The Australian National University (ANU) shows. 

A Cornell-led research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to organic materials.

A research team led by the University of Southampton and UWE Bristol  has shown wearable electronic textiles (e-textiles) can be both sustainable and biodegradable.

Plant collections are full of surprises.

In southwestern Ghana, a patchwork of tropical forest lies among widespread farmland dotted with towns. 

Marine heatwaves are becoming more frequent and intense. The Arctic Ocean also suffers from this development: The absence of sea ice will lead to more extreme fluctuations in ocean temperatures, with abrupt temperature changes occurring at unprecedented rates.

In the Arctic, the old, multiyear ice is increasingly melting, dramatically reducing the frequency and size of pressure ridges.

Pollination by animals contributes to a third of global food production, but little research has been done into the extent to which the identity of pollinators, pollen and crop varieties influence fruit quality when it comes to the nutritional, sensory and commercial value of crops.

Scientists have long sought ways to help plants turn more carbon dioxide (CO₂) into biomass, which could boost crop yields and even combat climate change.
