Sessile filter feeders like this Carboniferous crinoid, the mushroom crinoid (Agaricocrinus americanus), were significantly less abundant after the Permian-Triassic extinction.

Life on Earth has a long, but also an extremely turbulent […]

Climate scientists Nicholas Balascio and Francois Lapointe working with an ice auger to drill in the 3.5m thick ice at South Sawtooth Lake, Ellesmere Island, Nunavut Territory, Canada. An ice auger extension is needed because the ice is so thick. Coring lake sediments can only be done after this tedious […]

Satellite imagery has revealed that two of the fastest-changing glaciers in Antarctica are fracturing and weakening faster than ever – the first step towards the glaciers disintegrating and causing sea levels to rise dramatically. Using observations from ESA, NASA and USGS satellites, the researchers explored the Pine Island and Thwaites Glaciers in the […]

Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study reported in the journal One Earth today (October 15, 2020) combining climate modeling and the fossil record in search of clues to what led to […]

Laser technology has been used to measure the volume and biomass of giant Californian redwood trees for the first time, records a new study by UCL researchers.

This data image shows the monthly average sea surface temperature for May 2015. Between 2013 and 2016, a large mass of unusually warm ocean water – nicknamed the Blob – dominated the North Pacific, indicated here by red, pink, and yellow colors signifying temperatures as much as three degrees Celsius […]

If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of […]

The CENOGRID shows Earth has experienced four distinct climate states over the last 66 million years. The detailed climatic changes of the past can be studied like a colorful barcode and provide context for ongoing anthropogenic change and how exceptional it is. Earth’s climate has gradually cooled for the last […]

Sea ice can act as an agent of climate change on a variety of timescales and spatial scales—it’s not just a passive responder to change. The Little Ice Age may have arisen “out of the blue,” from internal variability within the climate system, rather than in response to an external […]
