Earth’ inner core slowing down
Earth’s inner core, a hot ball of iron the size of Pluto, has stopped spinning faster than the planet’s surface and may now be rotating slower than it, new research shows.

Reactions between rocks, rain and carbon dioxide in the atmosphere have helped to stabilize the climate throughout Earth’s history, but they won’t help prevent our carbon emissions from causing severe warming, a new study shows. However the results could help us find better ways to trap CO2 and slow climate change.
In a new study, EPFL professor Tom Battin reviews our current understanding of carbon fluxes in the world’s river networks. He explains their central role in the global carbon cycle and warrants for the creation of a global River Observation System.
Every year, the transfer of carbon-rich particles across the shelf in the Kara and Barents Seas could trap as much as 3.6 million metric tons of CO2 in the deep Arctic ocean for thousands of years.
The world’s oceans were the hottest ever recorded in 2022, indicating the profound and pervasive changes that human-caused emissions have made to the planet’s climate.
More than 400 miles below us is a massive world of extreme temperatures and pressures that has been churning and evolving for longer than humans have been on the planet. A new model from Caltech researchers shows that the processes involved are actually opposite to what had been previously theorized.
A new study conducted by Virginia Tech geobiologists suggests that the cause of the first known mass extinction of animals was decreased global oxygen availability, leading to the loss of a majority of animals present near the end of the Ediacaran Period roughly 550 million years ago.
Geologists are looking for a site that best demonstrates how humans have changed the structure of our planet’s surface. This place will best illustrate when a new epoch called the Anthropocene was born and its predecessor called the Holocene came to an end.
