Evidence of Antarctic glacier’s tipping point confirmed for first time
Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.
Examining the impact of climate change on Siberia’s stores of permafrost
Northumbria University is to play a leading role in a major study to assess the long-term impact of global warming on Siberia’s thawing permafrost.
Permafrost is frozen ground that stores vast amounts of fossil carbon. Given that permafrost holds twice as much carbon as the atmosphere, and that almost a quarter of the Northern Hemisphere is covered in permafrost, this frozen land plays an essen
Blanket of rock debris offers glaciers more protection from climate change than previously known
A new study has revealed that the expanse of rock debris on glaciers, a factor that has been ignored in models of glacier melt and sea level rise, could be significant. The Northumbria University study is published in Nature Geoscience this week and is the first to manually verify the rock debris cover on every one of the Earth’s glaciers.
New discovery: Evidence for a 90-million-year-old rainforest near the South Pole
Researchers have found unexpected fossil traces of a temperate rainforest near the South Pole 90 million years ago, suggesting the continent had an exceptionally warm climate in prehistoric times. Their findings are published today (1 April) as the lead story in the scientific journal Nature.
First evidence that Antarctica's thinning ice shelves are causing more ice to move from the land into the sea
Researchers have produced the first physics-based quantifiable evidence that thinning ice shelves in Antarctica are causing more ice to flow from the land into the ocean. Their findings have been published in Geophysical Research Letters.
Northumbria scientist embarks on ambitious mission to Antarctica’s Thwaites Glacier
A Northumbria University researcher is one of almost 100 scientists and support staff who have travelled to Antarctica this week (15 November 2019) for the most ambitious mission to date for Thwaites Glacier in West Antarctica.
£4m study to investigate if climate change will drive the Antarctic Ice Sheet towards a tipping point
A major £4 million EU-funded study to investigate how changes in Antarctica’s ice sheets and shelves may lead to a large and irreversible rise in global sea level over the coming decades is about to begin. Experts from the UK, Norway, Germany and France will work together to investigate the likelihood of abrupt changes in the movement of ice in the Antarctic region over the next 100 years.
