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.

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.

Botany professor Ansgar Kahmen has been studying Switzerland’s forests for years. 

Wildfire risk is no longer confined to the places people expect. 

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

As of June 2026, El Niño has officially arrived.

A study led by Newcastle University involving the community in Lunana, Bhutan, found that while there was a high awareness of the risk of glacial lake outburst floods (GLOFs) among people in Lunana - much of it as a result of ongoing government communications and outreach work - many residents were not sufficiently prepared to respond quickly and safely when warnings occurred.

A new study published in Nature Climate Change reveals a more complex reality: some tree species are moving uphill, while others are shifting downhill, and the key to understanding these contrasting responses lies in how trees manage water.

Collecting rainwater from rooftops and using it to spray buildings during hot weather could help cities cut air conditioning use, lower urban temperatures and lessen the impact of heatwaves, according to new research from The University of Manchester.
