In first-of-its-kind research, NOAA scientists and academic partners used 100 years of microscopic shells to show that the coastal waters off California are acidifying twice as fast as the global ocean average — with the seafood supply in the crosshairs.

The impact of an asteroid or comet is acknowledged as the principal cause of the mass extinction that killed off most dinosaurs and about three-quarters of the planet’s plant and animal species 66 million years ago.

Mini-microplastics uncovered in the stomachs of filter-feeding marine organisms.

Safe nuclear waste storage, new ways of generating and storing hydrogen, and technologies for capturing and reusing greenhouse gases are all potential spinoffs of a new study by University of Guelph researchers.

Modeling mercury release from soil erosion could help mine-heavy, deforested regions create helpful policies.

An international team co-led by an Oregon State University chemistry researcher has uncovered a better way to scrub carbon dioxide from smokestack emissions, which could be a key to mitigating global climate change.

New research shows road salt runoff into Mirror Lake in Adirondack Park prevents natural water turnover and therefore poses a risk to the balance of its ecology.

As the climate changes, myriad animal populations are being impacted. In particular, Arctic sea-ice is in decline, causing polar bears in the Barents Sea region to alter their feeding and hunting habits. 

Understanding what influences the amount of methane in the atmosphere has been identified by the American Geophysical Union to be one of the foremost challenges in the earth sciences in the coming decades because of methane’s hugely important role in meeting climate warming targets.

The identification of natural carbon sinks and understanding how they work is critical if humans are to mitigate global climate change.
