The West Antarctic Ice Sheet is melting rapidly, raising concerns it could cross a tipping point of irreversible retreat in the next few decades if global temperatures rise 1.5 to 2.0 degrees Celsius (2.7 to 3.8 degrees Fahrenheit) above preindustrial levels.

Joan Casey lived through frequent wildfire-season power outages when she lived in northern California.

In the race to make the world more livable for people and nature, progress on land is outpacing successes in the seas, raising red flags that wealthier countries’ advantages may be upsetting a balance, a Michigan State University study shows.

Scientists believe little more than 10% of the species that live in our seas have been found and that around two million remain undiscovered.

In late-April 2023, a severe geomagnetic storm in Earth’s magnetosphere led to an especially vivid display of the aurora.

The Catalonia region of Spain is experiencing a long-term drought, which has shrunk reservoirs and led to water restrictions.

In April 2016, a warm front approached southwest Greenland, causing air temperatures in the capital city of Nuuk and the surrounding area to increase rapidly.

Researchers have figured out a way to predict bacteria’s environmental pH preferences from a quick look at their genomes, using machine learning.

On April 21, 2023, a coronal mass ejection (CME) erupted from the sun, spewing out a burst of plasma that raced toward Earth at nearly two million miles per hour and generated a severe geomagnetic storm (level 4 out of 5 on NOAA’s space weather G- scale) at 3:26 p.m. EDT on April 23.

The green hydrogen economy is a sustainable alternative to fossil fuels. However, one of the challenges of constructing a global hydrogen economy is hydrogen transportation by sea. A new paper proposes solid air as a medium for recycling cold energy across the hydrogen liquefaction supply chain.
