Scientists have trained an artificial intelligence or AI system to accurately map in one-hundredth of a second the surface area and outline of giant icebergs captured on satellite images. It is a major advance on existing automated systems which struggle to distinguish icebergs from other features in the image. Human or manual interpretation of the satellite imagery is the other option...
Deforestation in the Amazon causes land surfaces up to 100 kilometres away to get warmer, according to a new study. The research, by a team of British and Brazilian scientists, led by Dr Edward Butt at the University of Leeds, suggests that tropical forests play a critical role in cooling the land surface – and that effect...
Humanity is rapidly reaching the limit for how much additional carbon can be emitted into the atmosphere to keep global warming within 1.5°C, according to a new research. If emissions stay at current day levels, what is known as the “remaining carbon budget” will be exhausted before the end of the decade. Dr Chris Smith,...
71 of the 162 ice shelves that surround Antarctica have reduced in volume over 25 years from 1997 to 2021, with a net release of 7.5 trillion tonnes of meltwater into the oceans, say scientists. They found that almost all the ice shelves on the western side of Antarctica experienced ice loss. In contrast, most...
New measurements of how boundary between onshore glacier and floating ice shelf glides back-and- forth could help predict melting. Most Antarctic glaciers flow straight into the ocean where they form large floating ice shelves. The grounding line is the place where the base of the ice firsts lifts off the sea floor and begins to...
