29 de ene. de 2021 · In total, the rate of ice loss has increased by 65 percent between 1994 and 2017. Overall, between 1994 and 2017, planet Earth lost 28 trillion tonnes of ice. To put that in perspective, that would be equivalent to a 100-meter-thick sheet of ice the size of the U.K. This melting ice has been the most concerning in two polar climates: Antarctica ...
18 de nov. de 2019 · Johnny Wood. A new time-lapse video shows arctic ice melting off the coast of Greenland, with just 5% of the original mass remaining. The oldest and thickest ice has been replaced by thinner ice, which melts more easily. Researchers say climate change is to blame for continued loss.
11 de may. de 2017 · The Anthrax outbreak, which saw up to 20 people hospitalised, was blamed on unusually warm weather in the arctic circle. It is believed that a reindeer carcass infected with Anthrax was buried deep in the ice, but with temperatures reaching 35C in the Siberian tundra last summer, the carcass thawed and Anthrax spores were released.

15 de nov. de 2023 · Antarctica is now the best-mapped continent on Earth. The air above Antarctica is also heating up, causing surface melting that can trigger the collapse of ice shelves. In March 2022, East Antarctica was hit by the most extreme heatwave ever recorded on Earth, with temperatures soaring 38℃ above normal. If this heatwave had occurred in the ...
5 de abr. de 2018 · As glaciers slip into the sea they create enormous ice shelves. Warmer waters cause these ice shelves to become thinner, and in some cases break off completely, exposing the glacier and speeding up sea level rise. There are two glaciers in particular, Pine Island and Thwaites, in West Antarctica, that are concerning the scientists.
7 de oct. de 2021 · Projected sea-level rise will have widespread effects around the world. The Antarctic ice sheet is the largest mass of ice in the world, holding around 60% of the world’s fresh water. If it all melted, global average sea levels would rise by 58 metres. But scientists are grappling with exactly how global warming will affect this great ice sheet.
The 2050 Climate Change Index ranked the Thai capital of Bangkok as the world’s most vulnerable city to sea level rises. A fifth of the city was reported underwater in 2011 when the region suffered its worst Monsoon flooding. More than 500 people were reported to have died. Bangkok is the world’s city most at risk from flooding due to ...
14 de feb. de 2020 · Erosion and landslides have become a problem without the ice that once held the soil together. Permafrost thaw ponds in Hudson Bay, Canada Image: Steve Jurvetson/Flickr Permafrost – any area of land that remains frozen for at least two years – can vary from less than a metre thick to more than 1,500 metres.
