Environment and ecosystems

Earth's air circulation systems, which help spread and disperse moisture and heat throughout the world, have been weakening over the years. New studies point to human activity.

This breakthrough study sheds light into the dangerous phenomenon of “river avulsion," a process that has shaped human history through devastating floods and continues to threaten millions of people worldwide.

Temperature increases associated with human-induced climate change do not manifest as small, even increases everywhere on the planet. Rather, they result in more frequent and severe episodes of heat waves, as the world saw in 2024.

Since April 2023, global sea surface temperatures have been continuously hotter than any period on record — and by a wide margin.

The Duck Creek Tributary’s newly restored, meandering shape helps reduce the flooding of nearby roads. It’s teeming with wildlife, too.

This issue discusses biodiversity impacts on climate change and explores interlinked relationships.

A study has found that Global South cities have just 70% of the “cooling capacity” provided by urban greenery in the Global North.

This paper combines predictions of agricultural suitability under different climate change scenarios with timber-production maps to show that 240–320 Mha (20–26%) of current forestry land will become more suitable for agriculture by 2100.
