Aurora create speed bumps in space

A new study finds a type of high-altitude aurora are responsible, at least in part, for moving pockets of air high into the atmosphere where they can cause drag on passing satellites.

Extended winter polar vortices chill Saturn’s strangely familiar moon, Titan

Saturn’s hazy moon Titan has a long-lived Earth-like winter polar vortex supercharged by the moon’s peculiar chemistry. A new study finds Titan’s northern hemisphere polar vortex sticks around past the moon’s summer solstice, into what would be late June on Earth, lasting three-quarters of a Titan year, or about 22 Earth years.

California ‘browning’ more in the south during droughts

Like a climate chameleon, California turned brown during the 2012–16 drought, as vegetation dried or died off. But the change wasn’t uniform. Large areas of the northern part of the state were not severely affected, while Southern California became much browner than usual…

Chemical tracers untangle natural gas from agricultural methane emissions

With natural gas booming across the Front Range, drilling rigs may operate within feet from cattle farms. That shared land use can confound attempts to understand trends in methane, a greenhouse gas and air pollutant—the gases emitted from these different sources blend together.

Deep diving robots find warming accelerating in South Pacific Ocean waters

The coldest, near-bottom South Pacific waters originating from Antarctica are warming three times faster than they were in the 1990s, according to new research analyzing data from deep-diving ocean robots and research cruises.

Mediterranean hurricanes expected to increase in strength by end of century

Hurricane-strength storms in the Mediterranean could hit the region with increasing power by the end of the 21st century, growing to robust Category 1 strength, according to a new study in the AGU journal Geophysical Research Letters.

Climate change may push Santa Ana fire season into winter months

Climate models predict a narrowing of the Santa Ana season in tandem with the wet season in Southern California over the next century, which could leave vegetation dry and fire-prone as winds peak in December and January, according to a new study.

Two- to three- fold increase in heatwave occurrence and severity seen directly in UK temperature records

A two- to three-fold increase in heatwave activity in the United Kingdom since the late 19th century has been identified in a new analysis of historical daily temperature data.

New study quantifies deep reaction behind “superdeep” diamonds

By Joshua Rapp Learn Whether they are found in an engagement ring or an antique necklace, diamonds usually generate quick reactions from their recipients. Now, new research shows deep inside the Earth, fast reactions between subducted tectonic plates and the mantle at specific depths may be responsible for generating the most valuable diamonds. The diamonds mined most often around the world are formed in the Earth’s mantle at depths of …
