Researchers have identified a second line of symmetry dividing Earth into halves with equal reflectivity along the 27° east and 153° west meridians. The finding, based on 25 years of satellite data, reveals unexpected balance in clear-sky albedo, cloud reflectivity and ice-free ocean coverage. It may connect to the El Niño-Southern Oscillation and affect future geoengineering plans.

Researchers have determined that a unusual gravity hole beneath Antarctica formed due to slow movements of rock deep inside Earth over millions of years. The anomaly strengthened between 50 and 30 million years ago, coinciding with changes in the continent's climate. This discovery provides insights into how Earth's interior influences surface conditions like sea levels and ice sheets.

In 2023, Hektoria Glacier on Antarctica's Eastern Peninsula retreated eight kilometers in just two months, marking the fastest such event recorded. Nearly half of the glacier broke apart due to its position over a flat underwater bedrock. The discovery, detailed in a new study, highlights vulnerabilities in other Antarctic ice features.
