Robbie Mallett presents a slide showing a timeseries of Arctic sea ice decline at COP26

Let’s talk cryosphere, COP26

Robbie Mallett, a PhD student at the Centre for Polar Observation and Modelling, University College London, spoke to Sam Cornish about his experience in the Cryosphere Pavilion at COP26 in Glasgow. What was the Cryosphere Pavilion and why was it at COP26? COP26 is not just for politicians, it’s also a chance for scientists, particularly …

Surveying pollutants on a remote Arctic island

This summer, DPhil student Will Hartz joined a scientific expedition to the remote Norwegian island of Jan Mayen. In satellite imagery the island appears as a punctuation mark, adrift in the ocean. But this volcanic island is rooted in the bathymetric barrier that helps to define the circulation of the Greenland, Icelandic and Norwegian seas; …

Polar Forum researchers will reveal the climate potential of rewilding in the Arctic

This blog post comes from Jeppe A. Kristensen, Carlsberg Foundation Visiting Fellow based in the School of Geography and Environment. The king of the Pleistocene Siberian steppes, the woolly mammoth, is set to return after 3,900 years of extinction! This was the intriguing, yet highly controversial message that hit the world media in September this …

Warming Temperatures Are Driving Arctic Greening

As Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new collaborative study involving the University of Oxford and global institutions across the world, found the region has become greener, as warmer air and soil temperatures lead to increased plant growth. For the expanded story, …

Sea-ice-free Arctic makes permafrost vulnerable to thawing

  New research, published in Nature, led by scientists at the University of Oxford’s Department of Earth Sciences, and at the Geological Survey of Israel, provides evidence from Siberian caves suggesting that summer sea ice in the Arctic Ocean plays an essential role in stabilising permafrost and its large store of carbon.
