Asteroid impacts and volcanism have led to mass extinctions on our planet.

Has Life on Earth Survived More Than Five Mass Extinctions?

Scientists aren’t just arguing whether humans are causing a sixth mass extinction event now, but whether many more occurred in the past

Greta Thunberg addresses climate strikers at Civic Center Park in Denver, Colorado.

Greta Thunberg Is Publishing the 'Ultimate Guide' to Climate Change

The book will feature contributions from over 100 novelists, scientists and activists

Wildfires blazed through Big Sur in January 2022.

We Are Changing Climate Faster Than We Can Adapt, New IPCC Report Warns

Despite the 'irreversible' impacts of a warming planet, scientists emphasize there is still time to act

Scientists used satellites to get a birds-eye view of the jaw-dropping bolts.

Intense Lightning 'Megaflashes' Stretched Almost 500 Miles Across Three U.S. States

The bolts, which occurred in 2020, broke records for distance and duration

The recent explosion was so powerful that it obliterated parts of the volcanic island of Hunga Tonga-Hunga Ha'apai, splitting it in two.

NASA Says Tonga Eruption Was More Powerful Than an Atomic Bomb

The recent blast was the equivalent of 4 to 18 megatons of TNT, according to scientists

The explosion was likely the biggest volcanic eruption recorded anywhere on the planet in more than 30 years.

Why the Eruption in Tonga Was a 'Once-in-a-Millennium' Event for the Volcano

The blast, which sent tsunami waves across the Pacific, left thousands of Tongans without access to water and power

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

The project aims to quantify the impact of climate change on the species

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.

World's Largest Carbon Capture Plant Opens in Iceland

'Orca' will use geothermal energy to pull thousands of metric tons of carbon dioxide out of the atmosphere and pump it underground
