Arctic permafrost stores massive amounts of organic carbon in its frozen soils and deeper deposits.

As the world relies increasingly on critical minerals such as cobalt to fuel not just the green revolution but also everyday life, the United States may need to turn to domestic mining to meet its needs.

More than 100 engineers, utility leaders, scientists and public officials came together in the wake of January’s catastrophic Los Angeles firestorms to identify innovative strategies and emerging technologies that could build more resilient infrastructure, recognizing the broader challenges of growing climate and disaster risks.

Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury.

A new study found compound drought-heatwave events are rippling farther and lasting through the night, raising risks for southwestern North America.

The timing of emissions reductions, even more so than the rate of reduction, will be key to avoiding catastrophic thresholds for ice-melt and sea-level rise, according to a new Cornell study.

Microscopic plankton that regulate Earth’s climate and sustain ocean ecosystems take centre stage in a new awareness campaign.

Courant and Center for Data Science researchers have created a neural network that quickly and accurately simulates ocean circulation.

An analysis of forest-based projects funded through the sale of carbon credits shows that 10% of them may have a net warming effect on the climate because of the way they alter the Earth’s albedo, or how much sunlight is reflected back into space.

Global sea-level change has now been measured by satellites for more than 30 years, and a comparison with climate projections from the mid-1990s shows that they were remarkably accurate, according to two Tulane University researchers whose findings appear in Earth's Future, an open-access journal published by the American Geophysical Union.
