The virtual conferencing that has replaced large, in-person gatherings in the age of COVID-19 represents a drastic reduction in carbon emissions, but those online meetings still come with their own environmental costs, new research from the University of Michigan shows.

The Martian moon Phobos orbits through a stream of charged atoms and molecules that flow off the Red Planet’s atmosphere, new research shows.

Antarctic ice is melting, contributing massive amounts of water to the world’s seas and causing them to rise – but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years’ worth of satellite data indicates.

When aboveground storage tanks fail during a storm and their toxic contents spread, the threat to human health can and probably will flow downwind of the immediate area.

The researchers of the Institute for Atmospheric and Earth system research at the University of Helsinki have investigated how atmospheric particles are formed in the Arctic.

Trees are often heralded as the heroes of environmental mitigation. They remove carbon dioxide from the atmosphere, which slows the pace of climate change, and sequester nutrients such as nitrogen, which improves water and air quality.

The trend of tropical cyclones – commonly known as hurricanes or typhoons – increasingly moving towards coasts over the past 40 years appears to be driven by a westward shift in their tracks, say the study’s authors from Imperial College London.

For species to survive in the wild, maintaining connectivity between populations is critical. Without ‘wildlife corridors’, groups of animals are isolated, unable to breed and may die out.

Business closures. Travel restrictions. Working and learning from home. These and other dramatic responses to Covid-19 have caused sharp reductions in economic activity — and associated fossil fuel consumption — around the world.

Cities are not all the same, or at least their evolution isn’t, according to new research from the University of Colorado Boulder.
