New research has uncovered findings regarding the magnetic field that prevailed in the Middle East between approximately 10,000 and 8,000 years ago. Researchers examined pottery and burnt flints from archaeological sites in Jordan, on which the magnetic field during that time period was recorded.

New research is providing a better estimate of the amount of carbon in the Earth’s outer core, and the work suggests the core could be the planet’s largest reservoir of that element.

The breakup of the supercontinent and formation of the current Afro-Eurasia landmass were caused by movement of Earth’s tectonic plates. The position of these tectonic plates is preserved in magnetic fields in rocks. These remnant magnetic fields can help generate apparent polar wander paths (APWPs). Researchers have now constructed an APWP of southwest Japan and … Treading wander paths to uncover the geological history of southwest Japan

Ice losses from Thwaites Glacier in West Antarctica are currently responsible for roughly four percent of the global sea-level rise. This figure could increase, since virtually no another ice stream in the Antarctic is changing as dramatically as the massive Thwaites Glacier. Until recently, experts attributed these changes to climate change and the fact that … Thwaites glacier: Significant geothermal heat beneath the ice stream

Earthquakes typically last only a few seconds, although sometimes the shifts in the subsurface occur in slow motion. Understanding these ‘slow quakes’, known as ‘slow slip events’, and their interplay with the short – sometimes violent – tremors is critically important to define the seismic hazard and subsequent risk.

Global warming begets more, extreme warming, new paleoclimate study finds. Researchers observe a ‘warming bias’ over the past 66 million years that may return if ice sheets disappear.

A new study finds that researchers examining signs of past sea levels along various coasts may have failed to accurately correct for long-term ups and downs of the land itself.

Researchers have found that the extinction at the end of the Permian period coincided with a sudden spike and subsequent drop in the ocean’s oxygen content.

The rise and fall of sea levels influence the likelihood of volcanic eruptions on the Greek island of Santorini, new research has discovered. Analyzing the timings of eruptions over hundreds of thousands of years, the researchers found that a 40 meter fall in sea level is a crucial point beyond which eruptions are more likely … Sea levels influence eruptions on volcanic island

Geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. The result: the methane concentrations in the air after last year’s heat wave indicate that increased gas emissions came from limestone formations.
