Global warming is causing permafrost in the Arctic to thaw and sea ice to melt. As a result, coasts are less protected and are being eroded, while carbon stored in the soil and carbon dioxide are being released into the ocean and atmosphere.

A team of German astronomers, led by Professor Klaus Werner of the University of Tübingen, have discovered a strange new type of star covered in the by-product of helium burning. 

We typically think of plants strutting their best stuff aboveground: showy flowers, fragrant blossoms, and unique shapes abound. But their development belowground is equally magical.

Seagrass meadows play an important role in the marine carbon cycle and our climate. 

New research led by the University of Massachusetts Amherst definitively resolves a long-standing discrepancy in the geologic record that pitted studies of marine ice-sheet behavior against those that reconstructed past conditions on land. 

Algae are more than just the green scum that shows up on aquarium walls. 

The 1992 opening of the Alto Lindoso Dam on the border of Spain and Portugal flooded the town of Aceredo, Spain. 

A recent ecosystem modeling study conducted by Iowa State University scientists shows how crop production in the United States has led to an increase in the emissions of nitrous oxide, a potent greenhouse gas, throughout the last century.

A region of cooling water in the North Atlantic Ocean near Iceland, nicknamed the “Blue Blob,” has likely slowed the melting of the island’s glaciers since 2011 and may continue to stymie ice loss until about 2050, according to new research.

A month of intense rainstorms and two tropical cyclones has led to widespread flooding.
