Global warming's ever-increasing toll on the planet has been a focus of mitigation strategies in recent years, with carbon sequestration projects playing a more prominent role in drawing carbon dioxide out of the atmosphere ...
Glacial cyclicity of the Earth has often been considered on 100,000 year timescales, particularly for the Late Pleistocene (~11,700 to 129,000 years ago) swapping between periods of extensive polar and mountain glacier ice ...
The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C.
Modeling of Earth's response to global warming has suggested dry regions will become more arid and wet regions will experience more precipitation, with an uneven distribution of moisture in the atmosphere. With enhanced seasonality, ...
In their recent publication, "Why is Denali (6,190 m) so big? Caught inside the tectonic wake of a migrating restraining bend," Jeff A. Benowitz and a research team from the University of Massachusetts Amherst, Virginia Tech, ...
Molecular clock dates for the first animals to walk the Earth don't match the fossil record. Comparing the disparate DNA of two different species and extrapolating how long it would take for them to mutate from a common ancestor ...
A team of researchers from Columbia University has found that radiation levels from atomic testing in the Marshall Islands are still too high for human habitation. In their paper published in Proceedings of the National Academy ...
(Phys.org)—A new study shows that plant-consuming microorganisms that reside in coalbeds can convert plant carbohydrates into natural gas, potentially offering a sustainable, clean method of energy generation.
It's well-known that lightning is an electric current—a quick, powerful burst of charge that flows within a cloud or between a cloud and the ground. But surprisingly, scientists still don't fully understand how the initial ...
(Phys.org) —In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous ...
