The global study examined hourly records of temperature, cloud cover, specific humidity, and precipitation. (One of the Expedition 40 crew members aboard the International Space Station photographed this nighttime image showing city lights in at least half a dozen southern states from some 225 miles above the home planet. Lights […]

1979 – 2019 Throughout 2020, the Arctic Ocean and surrounding seas endured several notable weather and climate events. In spring, a persistent heatwave over Siberiaprovoked the rapid melting of sea ice in the East Siberian and Laptev Seas. By the end of summer, Arctic Ocean ice cover melted back to the second-lowest […]

1985 – 2015 A recent study of Greenland’s ice sheet found that glaciers are retreating in nearly every sector of the island, while also undergoing other physical changes. Some of those changes are causing the rerouting of freshwater rivers beneath the ice. In a study led by Twila Moon of the […]

Aleutian Islands are an archipelago comprising dozens of islands with 40 active and 17 dormant volcanoes. A researcher from MIPT has proposed a new explanation for the Arctic’s rapid warming. In his recent paper in Geosciences, he suggests that the warming could have been triggered by a series of great earthquakes. […]

ANIMATION Fishermen, swimmers, and seafood enthusiasts may already know the dangers of “red tides,” but a recent study in Frontiers in Climate shows that climate change is increasing the frequency of one type of highly toxic algal bloom off the US west coast. These algae produce a neurotoxin — called domoic acid — that […]

The unstable terrain that poses a landslide threat lies between the Cascade Glacier and Barry Arm Glacier, which has been steadily retreating over the last decade. The above satellite images show the glacier’s retreat from 2013 (above) to 2019 (below). Credit: NASA Earth Observatory images by Lauren Dauphin, using Landsat […]

Developed by EarthSystemData Ltd with the Tyndall Centre for Climate Change Research at the University of East Anglia (UEA), the free to download ‘ESD Research’ app […]

NASA scientists traverse Antarctica’s icy landscape, towing scientific instruments and cold-weather gear with them. The team was tasked with collecting ground data to verify the accuracy of measurements made by the IceSat-2 satellite.

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 […]
