According to a new NASA-led study, the world has lost 561 square miles (1,453 square kilometers) of salt marshes over the past 20 years. 

Industrial-scale injection of gases into geological rock reservoirs is of increasing importance for the energy sector for uses ranging from flushing out remaining fossil fuels to locking away CO2 emissions and preventing them from contributing to climate change.

Health benefits of using wind energy instead of fossil fuels could quadruple if the most polluting power plants are selected for dialing down, new study finds.

University of California scientists have a new way to demonstrate which neighborhoods returned to pre-pandemic levels of air pollution after COVID restrictions ended.

The calculation method is based solely on observations rather than models and scenarios. According to the study, international climate policy has to become even more ambitious.

New research will investigate how pollution impacts our country’s rivers, develop better monitoring methods and put forward solutions for better chemical management to improve water quality.

An interdisciplinary team of researchers at Worcester Polytechnic Institute (WPI) has developed a potential breakthrough in green aviation: a recipe for a net-zero fuel for planes that will pull carbon dioxide (CO2) out of the air.

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated a new technique, modeled after a metabolic process found in some bacteria, for converting carbon dioxide (CO2) into liquid acetate, a key ingredient in “liquid sunlight” or solar fuels produced through artificial photosynthesis.

This year’s Chesapeake Bay “dead zone” was the 10th-smallest observed since 1985, according to findings released today by the Chesapeake Bay Program and its partners, including the University of Michigan.

When pandemic-related lockdowns grounded planes and brought car traffic to a near standstill in early 2020, transport emissions plummeted, leading to a drop in levels of a short-lived gas that scrubs methane from the atmosphere.
