From the American West to Europe, droughts are drying up rivers, fueling destructive fires and reshaping ecosystems.

As record-breaking heat grips communities worldwide and Australia prepares for an intense El Niño summer, new research provides the first global review linking high temperatures and heatwaves to poorer mental health in children and young people.

Oxygen provides the driving force for many vital chemical reactions. Two well-known examples include respiration, the process that allows living things to break down food to release its energy, and combustion, reactions that produce heat and light.

Scientists have uncovered a previously unknown natural process that dramatically increases the number of cloud-forming particles in the Arctic atmosphere - potentially altering cloud cover, sunlight reflection, and future climate change.

The devastating impacts of marine heatwaves extend far beyond dying coral reefs and declining fisheries, with new research warning these extreme ocean warming events are posing a growing threat to humans’ physical and mental health.

Nearly 30 years ago, a simple question sent University of Washington researchers into the Puget Sound lowlands to look for birds. 

A multidisciplinary team has successfully tested a novel autonomous monitoring system designed to improve how environmental evidence is generated for decision-makers managing the sustainable future expansion of floating offshore wind.

Engineers have developed a strain of a common bacterial species that can feed exclusively on the three major sugars present in corn stalks. 

Just like on land, the ocean environment can experience heatwaves. 

As of June 2026, El Niño has officially arrived.
