A new catalyst turns carbon dioxide into useful fuels and chemicals really efficiently . It could pave way for large-scale CO2 recycling, researchers say.

The giant houses of wealthy Americans offset progress toward lower greenhouse gas emissions, report researchers. See the map.

Methane emissions have reached the highest levels on record, researchers say. And more than half of all methane emissions now come from human activities.

Swapping out a gas-powered Uber or Lyft vehicle with an electric car cuts emissions three times more than when an individual driver makes that switch, research finds.

A new study in Sub-Saharan African shows that increases in dust air pollution boosts infant mortality. Climate change could make things even worse, too.

Arctic permafrost stores one trillion metric tons of carbon. New research on photomineralization suggests more of that carbon will be released.

The drop in carbon dioxide emissions during the COVID-19 pandemic shows we can change our energy-hungry behavior—and how much further we have to go.

Just a handful of facilities that emit unusually high levels of toxic chemicals account for the majority of industrial pollution year after year.

It will take a long time and lots of data to figure out exactly how the COVID-19 pandemic has affected the environment, researchers say.

By 2050, sea ice at the North Pole could be gone, researchers say. But how long the disappearance lasts is up to us.
