Marine life plays a pivotal role in Earth's carbon cycle. Phytoplankton at the base of the aquatic food web take up carbon dioxide from the atmosphere, convert it to organic carbon, and move it around as they become food for other organisms. Much of this carbon eventually returns to the atmosphere, but some ends up sequestered in the deep ocean via a process called carbon export.

The vast Antarctic Ice Sheet holds more than half of Earth’s freshwater. In several places around the continent, the ice extends over the ocean, where it forms large floating shelves. Observations suggest many of these ice shelves are thinning as they melt from below, with implications for ocean dynamics, global sea level, and Earth’s climate.

Central Europe is typically not on most people’s radar when it comes to assessing volcanic risk. However, as recently as 11,000 years ago, volcanoes erupted in the Eifel Mountains of western Germany. For now, the Eifel volcanic field lies dormant, but multiple lines of evidence have hinted that new eruptions could one day occur. Now, Eickhoff et al.

On 4 August 1972, a burst of solar plasma rocked Earth’s magnetic field after hurtling through space for about 14.6 hours—the fastest Sun-to-Earth plasma journey ever recorded. The resulting space storm, one of several that occurred from 2 to 11 August, triggered widespread disturbances to electrical and communication grids and likely caused accidental detonations of U.S. undersea naval mines in North Vietnam.

Encircling Earth are the Van Allen radiation belts—vast, doughnut-shaped rings of highly energetic charged particles, mostly originating from the Sun, that are trapped by our planet’s magnetic field, or magnetosphere. The belts prevent dangerous radiation from reaching Earth’s atmosphere, but can also pose hazards to nearby spacecraft.
