Paleontologists have examined a large assemblage of dinosaur tracks and fossilized plants from the Nanushuk Formation, which crops out over much of the central and western North Slope of Alaska.

Paleoclimate data, also known as climate proxies, is essential for investigating past climate variability and can help assess the extent of recent climate change.

Paleoclimate data from the Greenland Ice Sheet shows where historical climate changes correspond with Biblical events.

A paleoclimate scientist breaks down what climate change really looks like.

Abstract. A new hypothesis suggests that forest cover plays a much greater role in determining rainfall than previously recognized. It explains how forested reg

Yellow crystals of elemental sulfur were revealed after NASA's Curiosity rover happened to drive over a rock and crack it open on May 30, 2024, according to the Curiosity team.

New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.

A numerical model combines with proxy temperature data to produce the most complete paleoclimate picture yet.

MIT researchers have confirmed that Earth harbors a "stabilizing feedback" mechanism that acts over hundreds of thousands of years to keep global temperatures within a steady, habitable range.

Called ferrihydrite, this iron mineral formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current hyper-arid environment.

The El Niño-Southern Oscillation, which is characterized by irregular alternations between anomalously warm (El Niño) and cold (La Niña) conditions, was present at least 250 million years in the past, and was often of greater magnitude.

Palm trees of the tribe Trachycarpeae once thrived in what is now subarctic Canada, according to an analysis of fossilized phytoliths -- microscopic siliceous structures produced in specific tissues by many plant families -- from Canada's Northwest Territories.

Using data gathered by China's Zhurong rover, planetary researchers have identified hidden layers of rock under the Martian surface that strongly suggest the presence of an ancient northern ocean.

Glacial cycles during the early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial cycles with 100,000-year periodicity during the Late Pleistocene.

The planet is on track to heat up at a much faster rate than scientists have predicted, meaning a key global warming threshold could be breached this decade,...

Fine silicate dust from pulverized rock generated by the Chicxulub impact played a dominant role in global climate cooling and the disruption of photosynthesis following the event.

A world-first model of paleoclimate and hydrology in Iran has highlighted favorable routes for Neanderthals and modern human expansions eastwards into Asia.

Homo erectus, an early member of the genus Homo, successfully navigated harsher and more arid terrains for longer in Eastern Africa than previously thought, according to new research.

East China Normal University's Dr. Yi-Hsuan Pan and colleagues showed that human ancestors went through a severe population bottleneck with about 1,280 breeding individuals between around 930,000 and 813,000 years ago

Paleoanthropologists have identified a population turnover in Western Europe at 28,000 years ago, isolates in western and eastern refugia between 28,000 and 14,700 years ago, and bottlenecks during the latest Ice Age.
