Neotropical cloud forests to lose what most defines them: clouds

In as few as 25 years, climate change could shrink and dry 60-80% of Western Hemisphere cloud forests, finds a study published today. If greenhouse gas emissions continue increasing as they have been, 90% of Western Hemisphere ...

Scientists measure severity of drought during the Maya collapse

The severity of drought conditions during the demise of the Maya civilisation about one thousand years ago has been quantified, representing another piece of evidence that could be used to solve the longstanding mystery of ...

Novel hydrogel harnesses air moisture for practical applications

High humidity causes discomfort and makes hot days feel more unbearable. A team of researchers from the National University of Singapore (NUS) has invented a novel gel-like material that not only effectively dehumidifies ...

Super-heatwaves of 55 C to emerge if global warming continues

Heatwaves amplified by high humidity can reach above 40°C and may occur as often as every two years, leading to serious risks for human health. If global temperatures rise with 4°C, a new super heatwave of 55°C can hit ...

MOF keeps humidity in the Goldilocks zone

A novel porous material can soak up excessive humidity in a room only to release it again when the humidity falls. Now KAUST researchers have devised a metal-organic framework (MOF) material that monitors its own properties.

Unraveling the mysteries of Arctic clouds

Clouds play a role in warming the Arctic and coinciding decreases in sea ice, but it is a complicated story. Using data from three Arctic sites, scientists studied the relationships among temperature, water vapor, and how ...
