An increase in rainfall could create a feedback loop that leads to more warming, the study authors conclude.

The Arctic Could Be Dominated by Rain Instead of Snow Within Decades

New research suggests that the transformation may happen faster than anticipated

Melting sea ice because of climate change forces walruses to congregate on land instead of ice.

Researchers Need Volunteer 'Walrus Detectives' to Help Count the Animals in Satellite Images

New research suggests that clouds affected by wildfire smoke hold more water droplets but are tiny and less likely drop as rain.

Smoky Clouds That Form Over Wildfires Produce Less Rain

Particles from the smoke create tiny droplets too small to fall to Earth

Orca will be able to capture the equivalent of the annual emissions made by 790 cars.

A new exhibition at the British Museum spotlights an ingenious way of life threatened by global warming

In one example of redlining, this Home Owners' Loan Corporation map depicts part of Chicago, Illinois and labels neighborhoods as "hazardous" (red) or "best" (green). Borrowers could be denied access to credit if their homes or businesses were located in "hazardous" neighborhoods, typically economically disadvantaged neighborhoods with large minority populations.

A growing body of research highlights the connection between systemic discrimination and the local climate

The total emissions released increased as temperatures rose, doubling when temperatures went from 104 degrees to 140 degrees Fahrenheit

On Hot Days, Asphalt Can Release as Much Air Pollution as Cars

During heat waves, pavement can reach 140 degrees Fahrenheit, which unleashes harmful particles into the air

This global map indicates the temperature differences between  now and preindustrial times, where dark blue translates to cooler temperatures.

Scientists Project Precisely How Cold the Last Ice Age Was

Researchers used models and data from fossilized plankton to determine the global average temperature at the time
