The Greenland Ice Sheet is rapidly melting, having lost 3.8 trillion tons of ice between 1992 and 2018, a new study from NASA and the European Space Agency (ESA) finds. The study combined 26 independent satellite datasets to track global warming’s effect on Greenland, one […]

Some of the biggest catfish and sea snakes to ever exist lived in what is today the Sahara desert, according to a new paper that contains the first reconstructions of extinct aquatic species from the ancient Trans-Saharan Seaway. The sea was 50 meters deep and once covered […]

Modeling simulations and comparisons with lunar impact studies have revealed that following Earth’s accretion about 4.6 billion years ago, Earth-shattering impacts continued to shape the planet for hundreds of millions of years. Although these events appear to have tapered off over time, Pilbara craton in Australia and Kaapvaal […]

For colorful, graceful sea fans swaying on coral reefs in the waters around Puerto Rico, copper is an emerging threat in an era of warming oceans. In an NSF-funded study published in the journal Ecological Applications, Cornell University scientists report evidence of metal pollution creating danger for soft coral sea […]

How small is the tiniest possible particle of ice? According to new NSF-funded research published in the journal Proceedings of the National Academy of Sciences, the smallest nanodroplet of water in which ice can form is only as big as 90 water molecules — a tenth […]

Fissures caused by melting of the Greenland ice sheet are threatening its stability, and now drone footage has shown the resulting water drainage is occurring more quickly than previously thought. Melting of this ice sheet – the second largest in the world, with three million […]
