When water pours inland, it can destroy coastal habitats and ecosystems that house birds, fish and plants. Aquifers and agricultural soil can be contaminated, coast lines can erode, and there is an increased risk for deadly floods. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Higher sea levels also mean greater storm surges that can destroy homes, kill humans and animals, and displace hundreds of thousands of people living on the coast. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">It sounds like something the world should try to avoid, right? Well, it might be too late. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sea-level rise will continue <\/span><a href=\"https:\/\/www.nature.com\/articles\/s41467-018-02985-8\"><span style=\"font-weight: 400;\">long after<\/span><\/a><span style=\"font-weight: 400;\"> greenhouse gas emissions are stopped. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">And some ice caps are melting faster than ever before. <\/span><\/p>\n<h2><b>Unparalleled depletion of Russian ice cap<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Over the past few years, Russia\u2019s Vavilov Ice Cap has melted and slid drastically faster than it ever had before, researchers from the <\/span><a href=\"https:\/\/cires.colorado.edu\/news\/unprecedented-ice-loss-russian-ice-cap\"><span style=\"font-weight: 400;\">University of Colorado Boulder find<\/span><\/a><span style=\"font-weight: 400;\">. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The ice cap, which traditionally moved at speeds of two inches per day, was sliding as much as 82 feet a day in 2015. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;In a warming climate, glacier acceleration is becoming more and more common, but the rate of ice loss at Vavilov is extreme and unexpected,&#8221; <\/span><a href=\"https:\/\/www.colorado.edu\/geologicalsciences\/michael-willis\"><span style=\"font-weight: 400;\">Mike Willis<\/span><\/a><span style=\"font-weight: 400;\">, an assistant professor of geology at CU Boulder and lead author of the study, said in a statement. <\/span><\/p>\n<p><iframe title=\"Vavilov Ice Cap Collapse Time-lapse\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/jeC47jxiuuA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><span style=\"font-weight: 400;\">In the 30 years before the speedup in 2015, the Vavilov Ice Cap only thinned by about 10 feet.

The findings have them worried that it could be happening to other major ice caps. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The researchers doubt that the ice cap will ever be able to recover its mass in this era of warming. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;We&#8217;ve never seen anything like this before, this study has raised as many questions as it has answered.&#8221; Willis said in a statement. &#8220;And we&#8217;re now working on modeling the whole situation to get a better handle of the physics involved.&#8221;<\/span><\/p>\n<h2><b>Mild warming could melt the world\u2019s largest ice sheet<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Global temperature rise of just 2 degrees Celsius would be enough to melt the East Antarctic Ice Sheet by several meters, researchers find in a <\/span><a href=\"https:\/\/sees.uq.edu.au\/article\/2018\/09\/moderate-warming-could-melt-east-antarctic-ice-sheet\"><span style=\"font-weight: 400;\">new study<\/span><\/a><span style=\"font-weight: 400;\">. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Such rise in temperature is not very much, considering it is the goal set by the Paris Agreement.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Until now, scientists\u2019 attention has primarily been focused on the western ice sheets in Antarctica, for many of them sit below sea level and are known to contribute the most to the continent\u2019s melting. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;Antarctica is around twice the size of Australia, with ice sheets several kilometres thick and containing around half of the world&#8217;s fresh water,&#8221; <\/span><a href=\"https:\/\/researchers.uq.edu.au\/researcher\/2023\"><span style=\"font-weight: 400;\">Kevin Welsh<\/span><\/a><span style=\"font-weight: 400;\">, a scientist in the School of Earth and Environmental Sciences at the University of Queensland in Australia and co-author of the study, said in a statement. <\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">&#8220;The East Antarctic Ice Sheet covers about two thirds of the area, and because its base is largely above sea level it was generally thought to be less sensitive to warming climates than the adjacent West Antarctic Ice Sheet,\u201d he continued. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The researchers claim that the ice sheet had melted in the late Pleistocene period when temperatures were similar to those predicted for this century.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;We found that the most extreme changes in the ice sheet occurred during two interglacial periods 125,000 and 400,000 years ago, when global sea levels were several metres higher than they are today,&#8221; Welsh said in a statement.<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">&#8220;These periods could be analogues for future climates and it seems likely that ice loss from the East Antarctic Ice Sheet contributed to those higher sea levels,\u201d he continued. <\/span><\/p>\n<h2><b>Conclusion<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The threats posed by sea-level rise are staggering, and with an increase in glacial melting, the world can expect the sea to rise at accelerated rates. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The only thing humans can do is continue to lower their emissions. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;With current global temperatures already one degree (Celsius) higher than during pre-industrial times, future ice loss seems inevitable if we fail to reduce carbon emissions,&#8221; <\/span><a href=\"http:\/\/davidcwilson.com\/\"><span style=\"font-weight: 400;\">David Wilson<\/span><\/a><span style=\"font-weight: 400;\"> a researcher from the Department of Earth Sciences at Imperial College London and lead author of the Antarctic study, said in a statement. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sea-level rise may be the biggest threat posed by climate change.
