Abrupt shifts within complex systems such as the Earth’s climate system are extremely hard to predict.

As the world’s largest unfrozen freshwater resource, groundwater is crucial for life on Earth. 

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. 

We may go to the woods seeking peace and quiet, but are we taking our noise with us? 

In early May, the neurotoxic effects of the heavy metal mercury made news when outlets reported that 2024 U.S. presidential candidate Robert F. Kennedy Jr. said in 2012 that he experienced cognitive issues such as memory loss due to mercury poisoning, likely from a diet heavy in tuna.

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. 

Declining snowfall is changing the seasonal patterns of streamflow throughout the Northern hemisphere boosting chances of water shortages in the summer, scientists have found.

A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom. 

Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to Penn State researchers.
