Glaciers ending in lakes, oceans or ice shelves make up 3.2% of the world’s glaciers, but lost 134bn tonnes of ice each year between 2000 and 2019, accounting for more than half of all glacier ice loss, a new study shows.

Reaching net zero sooner would limit long-lasting changes to El Niño and the tropical Pacific, new climate modelling suggests, although heat stored deep in the ocean means changes to the tropical Pacific could persist for centuries.

Two thousand years ago, the Arctic remnants of a once-vast ice sheet started to grow again. 

UB-led study of ancient sediment offers new insights into ice sheet retreat at the former Cold War outpost.

The research was led by Enikő Magyari, a researcher at the Department of Environmental and Landscape Geography, ELTE Faculty of Science, and head of the DOMINO-CLIMATE Élvonal project.

Based on aerosol–cloud interaction, the Arctic region is composed of three distinct ‘regimes’, as demonstrated in a study published in the Nature Geoscience journal.

Researchers at the University of Helsinki wanted to understand which is the dominant factor for species occurrence and abundance: the climate or habitat-related variables, such as their natural state and the share of land shaped by human activity.

When Environment and Climate Change Canada (ECCC) urged Montrealers to limit outdoor activity during Canada’s worst wildfire smoke episodes, the city’s travel patterns shifted – but far less than public health officials might have hoped, according to a new McGill University study.

Researchers at Oregon State University have developed a new family of materials that use light to produce hydrogen from water, opening the door to new ways of converting the sun’s rays into clean energy.

Rainwater tanks are a popular way for Australians to save water, but new research has found they can also harbour potentially harmful bacteria and metals that could pose health concerns.
