  • The importance of maintaining seagrass

    Seagrass meadows provide the ideal place for young fish to thrive, say NERC-funded scientists researching the importance of these habitats for commercial fishing. Globally seagrasses are being lost at the same rate as Amazonian rainforests, and little is being done to conserve these habitats as their importance isn’t fully understood. But scientists at Swansea University…

  • Defending against sea level rise could make the problem worse

    A combination of coastal defences and rising sea levels could change typical UK tidal ranges, potentially leading to a higher risk of flooding, say scientists. The researchers wanted to find out how tides around the UK might respond to changes in sea level over the next century depending on the level of coastal defences in…

  • Groundwater and Glaciers

    Subglacial lakes in Antarctica might have nutrient-rich groundwater flowing into them, say scientists investigating the origin of the water in ice streams. Ice streams are huge, fast-flowing glaciers that meander across Antarctica. They are responsible for nearly all of the Antarctic’s contribution to sea-level rise, yet scientists have little understanding of where the water flowing…

  • How mountain trees help regulate climate

    A new study, published in Geophysical Research Letters, shows that if global temperatures were to rise over geologic timescales, trees at higher elevations could play an important role in encouraging more carbon dioxide to be removed from the atmosphere. The team, from the Universities of Sheffield and Oxford, conducted their research in the Peruvian mountains,…

  • Pine Island Glacier is shrinking

    Pine Island Glacier, the largest single contributor to sea-level rise in Antarctica, has started shrinking, say scientists. The work, published in Nature Climate Change, shows the glacier’s retreat may have begun an irreversible process that could see the amount of water it is adding to the ocean increase five-fold. ‘At the Pine Island Glacier we…

  • Amazing study shows how dinosaurs walked

    For the first time scientists have learnt how the largest four-legged dinosaurs got from A to B. The new research, published in Plos ONE, wanted to understand how one of the biggest animals to have lived on Earth, the Argentinosaurus, walked. The Argentinosaurs, at 80 tonnes and 40m long was the equivalent of fifteen elephants,…
