Earth’s global average surface temperature in 2021 tied with 2018 as the sixth warmest on record, according to independent analyses done by NASA and NOAA. Collectively, the past eight years are the warmest years since modern recordkeeping began in 1880.

Researchers have new insight into the complicated puzzle of environmental conditions that characterized the Late Ordovician Mass Extinction (LOME), which killed about 85% of the species in the ocean.

A reexamination of Earth‘s famous ‘whiff of oxygen’ has the potential to rewrite early accounts of the planet’s history by finding that atmospheric oxygen actually did not exist prior to the Great Oxygenation Event (GOE).

During long portions of the past 2.4 billion years, the Earth may have been more ‘inhospitable’ to life than scientists previously thought, according to new computer simulations. Using a state-of-the-art climate model, researchers now believe the level of ultraviolet (UV) radiation reaching the Earth‘s surface could have been underestimated, with UV levels being up to … Study reveals more hostile conditions on Earth as life evolved

Down near the Earth’s core, there are zones where seismic waves slow to a crawl. New research finds that these enigmatic and descriptively-named ultra-low velocity zones are surprisingly layered. Modeling suggests that it’s possible some of these zones are leftovers from the processes that shaped the early Earth — remnants of incomplete mixing like clumps … Possible chemical leftovers from early Earth sit near the core

Atmospheric carbon dioxide (CO2) levels have increased significantly over the last 50 years, resulting in higher global temperatures and abrupt changes to Earth’s climate. Carbon capture and storage (CCS) is one of the new technologies that scientists hope will play an important role in tackling the climate crisis. It involves the capture of CO2 from … Safer carbon capture and storage

A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant waves.

An unknown culprit has been removing oxygen from our atmosphere for at least 800,000 years, and an analysis of air bubbles preserved in Antarctic ice for up to 1.5 million years has revealed the likely suspect.

Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis. This research provides new insight that connects the characteristics of earthquakes — magnitude, depth where two tectonic plates slip past each other and the rigidity of the plates involved — … Earthquake depth impacts potential tsunami threat
