Scientists are advancing a promising solution to two of the world’s biggest challenges – plastic pollution and clean energy – by transforming waste plastics into valuable fuels using sunlight.

A study led by the University of Barcelona and published in the journal Nature Communications shows that climate change has profoundly altered extreme episodes of melting of the Greenland ice sheet: it has made them more frequent, more extensive and more intense. 

Tiny particles of plastic amassing in the atmosphere may be intensifying warming, according to new study. 

When oak trees are heavily damaged by caterpillars, they open buds later the following spring. 

The World Stroke Organization is warning that climate change poses an escalating threat to brain health, with extreme heat in particular increasing the risk of having a stroke and of patients dying from stroke.

While the world is a big place, humans are making greater and greater demands on the same areas of land. 

With unprecedented clarity, scientists have directly observed a subduction zone—the collision point where one tectonic plate dives beneath another—actively breaking apart. 

The Pacific Ocean is a giant climate cauldron, with a powerful heat engine that affects storms, fisheries and rainfall patterns half a world away, and scientists are watching closely to see if it’s about to boil over. 

Snow cover in the mountains of Greece – an important water source for communities, agriculture and natural ecosystems during the dry summer months – has more than halved over the past four decades, a study has found.

The evolutionary edge that fueled great white shark dominance for millions of years could soon become its greatest downfall.
