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. 

Capping production of new plastics will help cut their release to the environment — and brings other benefits, from boosting the value of plastics to helping tackle climate change.

As the Earth’s climate continues to warm, researchers predict wild animals will be forced to relocate their habitats — likely to regions with large human populations — dramatically increasing the risk of a viral jump to humans that could lead to the next pandemic.

EPA has included a comparison of NOAA’s atmospheric emission estimates of four HFCs to its own inventory-based estimates in the just-released U.S. Inventory of Greenhouse Gas Emissions and Sinks
