Dust storms and other weather phenomena offset some reductions in PM2.5 aerosol pollution.

Scientists are flying an airborne campaign out of NASA's Langley Research Center in Hampton, Virginia this month to contribute to a joint U.S.-Canadian study on air quality in a region with high surface ozone levels.

Scientists from the University of Michigan have developed an innovative way to use NASA satellite data to track the movement of tiny pieces of plastic in the ocean.

Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth’s atmosphere are not equal to the climate changes from deliberate CO2 removals—and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new Simon Fraser University-led research.

Earth bears many signs of human influence, from warming that exceeds pre-industrial temperatures to a rising sea.

May was arguably the worst month ever for big oil — and the best for its opponents — as courts and corporate shareholders sided with environmental activists to humble the biggest of the fossil-fuel giants, culminating in “Black Wednesday.”

What do pipes and anchors have to do with storing energy? More than you might think! 

A potent greenhouse gas, methane is released by many sources, both human and natural. Large cities emit significant amounts of methane, but in many cases the exact emission sources are unknown.

Communities surrounding the Salton Sea, the inland body of water straddling California’s Riverside and Imperial counties, show high rates of asthma due, possibly, to high aerosol dust levels resulting from the sea shrinking over time.

As you drive down the highway, you may notice an increasing number of hybrid and electric vehicles.
