We are made of stardust, the saying goes, and a pair of studies including University of Michigan research finds that may be more true than we previously thought. The first study, led by U-M...
Tropical rainforests today are biodiversity hotspots and play an important role in the world's climate systems. A new study published today in Science sheds light on the origins of modern rainforests and may help scientists understand how rainforests will...
Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.
A vast global ocean may have covered early Earth during the early Archean eon, 4 to 3.2 billion years ago, a side effect of having a hotter mantle than today, according to new research.
Earth has experienced five major mass extinction events over the past 500 million years. Massive volcanic eruptions have been identified as the major driver of the environmental changes that precipitated at least three of these extinction events....
Earth is on a budget—an energy budget. Our planet is constantly trying to balance the flow of energy in and out of Earth's system. But human activities are throwing that off balance, causing our planet to warm...
The high temperatures and pressures of the Earth's mantle forge carbon-rich minerals known as carbonates into diamond. But less is known about the fate of carbonates that travel even deeper underground—depths from which no sample has ever...
New research shows that naturally occurring climate variations help to explain a long-standing difference between climate models and satellite observations of global warming. Satellite measurements of global-scale changes in atmospheric temperature began in late...
Human actions are threatening the resilience and stability of Earth's biosphere—the wafer-thin veil around Earth where life thrives. This has profound implications for the development of civilization, say an international group of researchers in a report published...
Beneath the cold, dark depths of the Arctic ocean sit vast reserves of methane. These stores rest in a delicate balance, stable as a solid called methane hydrates, at very specific pressures and temperatures. If that balance...
A new type of rock created during large and exceptionally hot volcanic eruptions has been discovered beneath the Pacific Ocean. An international team of researchers including the University of Leeds unearthed the previously unknown...
