Earth system scientists at the University of California, Irvine and other institutions have drawn the clearest line yet connecting consumers of agricultural produce in wealthier countries in Asia, Europe and North America with a growth in greenhouse gas emissions in less-developed nations, mostly in the Southern Hemisphere.

A new study has revealed super cyclones, the most intense form of tropical storm, are likely to have a much more devastating impact on people in South Asia in future years.

Staggering declines in bird populations are taking place around the world.

Human activities such as marsh draining for agriculture and logging are increasingly eating away at saltwater and freshwater wetlands that cover only 1% of Earth’s surface but store more than 20% of all the climate-warming carbon dioxide absorbed by ecosystems worldwide.

Native species in California's estuaries are expected to experience greater declines as invasive species interact with climate change, according to a study from the University of California, Davis.

A new study has revealed the most intense heatwaves ever across the world – and remarkably some of these went almost unnoticed decades ago.

In the Sierra Nevada, midwinter “rain-on-snow” events occur when rain falls onto existing snowpack and have resulted in some of the region’s biggest and most damaging floods. 

The new paper, published in Environmental Research Letters, highlighted how storing carbon in forests could tackle climate change.

During the last ice age, glaciers covered vast portions of North America.

Protected areas — such as nature reserves, national parks, and wilderness areas — are essential to conserving biodiversity.
