New measurement device: Carbon dioxide as geothermometer

For the first time, it is now possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature ...

New tree ring analysis method may open insights to past climate

Satellite imagery of earth's vegetation, measurements of carbon dioxide in the air and computer models all help scientists understand how climate is affecting carbon dynamics and the world's forests. But these technologies ...

Research suggests life thrived on Earth 3.5 billion years ago

Three and a half billion years ago, Earth hosted life, but was it barely surviving, or thriving? A new study carried out by a multi-institutional team with leadership including the Earth-Life Science Institute (ELSI) of Tokyo ...

Devonian integrative stratigraphy and timescale of China

Studies on the Devonian of China have lasted for about 170 years, and important progress has been made recently. Based on well-studied bio- and chronostratigraphy of the Devonian in South China and adjacent areas, in combination ...

Time travel with bat guano

To help determine forest restoration goals in Costa Rica, postdoctoral scholar Rachel Reid will travel to Central America this winter to explore a cave long inhabited by bats. The work is supported by WashU's Living Earth ...

Earth's oxygen increased in gradual steps rather than big bursts

A carbon cycle anomaly discovered in carbonate rocks of the Neoproterozoic Hüttenberg Formation of north-eastern Namibia follows a pattern similar to that found right after the Great Oxygenation Event, hinting at new evidence ...
