Microplastics are everywhere, even in the most remote places. Where do these tiny pieces of plastic come from? 

At first glance, Antarctica seems inhospitable. Known for howling gales and extremely cold temperatures, the continent is blanketed with a mile-thick ice shelf. 

Alternative-energy research at Oregon State University is charting a path toward the mass adoption of clean cars powered by direct-ethanol fuel cells.

Just like cars need fuel to run, microorganisms need energy to live.

Sea-level rise is one of the most immediate consequences of climate change, as highlighted recently through urgent pleas from leaders of island nations at the COP26 summit.

Greenland’s glaciers grind rock into a fine powder that discolors meltwater and often makes beautiful patterns as it mixes with seawater.

A team of international researchers from Canada, Colombia, and Germany has discovered a new marine reptile.

A civil and environmental engineering researcher at the University of Massachusetts Amherst has, for the first time, assimilated satellite information into on-site river measurements and hydrologic models to calculate the past 35 years of river discharge in the entire pan-Arctic region.

The Antarctic Circumpolar Current (ACC), the only ocean current that circumnavigates the planet, is speeding up. For the first time, scientists are able to tell that this is happening by taking advantage of a decades-long set of observational records.

Mitigation pathways exploring end-of-century temperature targets often entail temperature overshoot, that is the extent to which temperature is allowed to temporarily exceed a given target.
