Evidence from an Arctic ecosystem experiencing rapid climate change reveals surprisingly tight coupling of environmental responses to climate shifts. Links between abrupt climate change and environmental response have long been considered delayed or dampened by internal ecosystem dynamics, or only strong when climate shifts are large in magnitude. The research team presents evidence that climate shifts of even moderate magnitude can rapidly force strong, pervasive environmental changes across a high-latitude system.

Underneath their tough exteriors, some crocodilians have a sensitive side that scientists could use to shine light on our ancient climate.

A new study shows that over the past 10,000 years, humanity has experienced a number of foundational transitions, or 'bottlenecks.' During these periods of transition, the advance or decline of societies was related to energy availability in the form of a benign climate and other factors.

Newly developed geological techniques help uncover the most accurate and high-resolution climate records to date, according to a new study. The research finds that the standard practice of using modern and fossil coral to measure sea-surface temperatures may not be as straightforward as originally thought. By combining high-resolution microscopic techniques and geochemical modeling, researchers are using the formational history of Porites coral skeletons to fine-tune the records used to make global climate predictions.

Leading microbiologists have issued a warning, saying that not including microbes -- the support system of the biosphere -- in the climate change equation will have major negative flow-on effects.

A new study of climate changes and their effects on past societies offers a sobering glimpse of social upheavals that might happen in the future. The prehistoric groups studied lived in the Amazon Basin of South America hundreds of years ago, before European contact, but the disruptions that occurred may carry lessons for our time.

A nearly 100-year-old physics model captures the essential mechanism of pattern formation and geometry of Arctic melt ponds.

Researchers have presented support for the theory that marine invertebrates with larger body size are generally more sensitive to reductions in oxygen than smaller animals, and so will be more sensitive to future global climate change. However, evolutionary innovation can to some extent offset any respiratory disadvantages of large body size.

Warming waters in the western tropical Pacific Ocean have significantly increased thunderstorms and rainfall, which may affect the stability of the West Antarctic Ice Sheet and global sea-level rise, according to a new tudy.

In a new study, researchers confirm a theory from the 1970s that coastal hunter-gatherers processed much of their shellfish at the beach before returning with their meat to camps on higher ground, leaving the heavy shells by the water. This finding has dramatic implications for past analyses of hunter-gatherer diets -- because many beachside shell middens would now be destroyed or underwater due to past sea level rises since the last Ice Age.

Using rare oxygen molecules trapped in old ice and snow, US and French scientists have answered a long-standing question: How much have 'bad' ozone levels increased since the start of the Industrial Revolution?

Why did a giant hole appear in the sea ice off Antarctica in 2016 and 2017, after decades of more typical sea ice cover? Years of Southern Ocean data have explained the phenomenon, helping oceanographers to better predict these features and study their role in global ocean cycles.

Drone surveys have revealed extreme erosion on the Arctic coastline, highlight the ongoing change in the region in a warming climate.

The transition to plate tectonics started with the help of lubricating sediments, scraped by glaciers from the slopes of Earth's first continents, according to new research.

A new study of Patagonia's ice fields finds that many glaciers in the region are much thicker than previously thought.

An ancient, cosmopolitan lineage of plants is shaking up scientists' understanding of how quickly species evolve in temperate ecosystems and why.

Identifying the movements of extinct species from millions of years ago can provide insights into ancient migration routes, interaction between species, and the movement of continents.

A mass die-off of seabirds in the Bering Sea may be partially attributable to climate change, according to a new study.

Northern and Central Asia have been neglected in studies of early human migration, with deserts and mountains being considered uncompromising barriers. However, a new study argues that humans may have moved through these extreme settings in the past under wetter conditions. By analyzing past climate, northern Asia emerges as a potential route of human dispersal, as well as a zone of potential interaction with other hominins such as Neanderthals and Denisovans.

A new study assesses the contribution that Asia's high mountain glaciers make to relieving water stress in the region. The study has important economic and social implications for a region that is vulnerable to drought. Climate change is causing most of the region's glaciers to shrink.
