A new study shows that disappearing sea ice is a significant element of the food web supporting female walruses and their dependent young in the Arctic’s Chukchi Sea. 

Most scientists agree climate change has a profound impact on U.S. agricultural production. 

The same phenomenon that causes aurorae -- the magical curtains of green light often visible from the polar regions of the Earth -- causes mesospheric ozone layer depletion. 

During climate extremes, plants cannot produce sufficient energy-rich carbon compounds through photosynthesis and they become dependent on stored reserves. 

Water “blisters” trapped beneath the thick interior of Greenland’s ice sheet could provide critical insight into the hydrological network coursing deep below Earth’s second largest body of ice — and how it might be destabilized by climate change, according to a new study.

Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide (CO2) over geological time.

Shortly after taking office in January, President Joe Biden directed federal agencies to procure “clean, zero-emission vehicles,” but work toward that goal has been slow — just 10 percent of new mail trucks ordered by the United States Postal Service are expected to be all-electric.

The island’s vast ice sheet underwent multiple bouts of widespread melting this summer, exacerbated in August 2021 by rain.

Vegetative health has become an important metric for climate scientists and meteorologists trying to understand how weather and temperature impact the health of crops, and as an extension, food security, food prices and the global agricultural market.

A $2.2 million National Science Foundation grant will establish the center, where scientists will research the farming of insects as a potential food source.
