A <a href=\"https:\/\/tc.copernicus.org\/articles\/20\/1071\/2026\/\" rel=\"nofollow noopener\" target=\"_blank\">new study<\/a> published in the journal Cryosphere reveals that the structures may have been caused by thermal convection in a process similar to the churning of the hot rock in Earth\u2019s mantle.<\/p>\n<p class=\"\" data-block=\"sciam\/paragraph\">Convection is caused by temperature differences within a material. Hot material rises, and cool material falls\u2014driving a cycling, or convection. The same phenomenon appears to occur in ice, too, indicating that parts of the ice sheet may be softer than scientists realized. That\u2019s important for one crucial reason: we know that Greenland\u2019s ice sheet is <a href=\"https:\/\/www.scientificamerican.com\/article\/greenland-is-disappearing-quickly-and-scientists-have-found-a-new-reason-why\/\" rel=\"nofollow noopener\" target=\"_blank\">rapidly melting<\/a>.

And that knowledge is critical\u2014the sheet is more than 650,000 square miles in size; by <a href=\"https:\/\/nsidc.org\/learn\/parts-cryosphere\/ice-sheets\/ice-sheet-quick-facts\" rel=\"nofollow noopener\" target=\"_blank\">one estimate<\/a>, if all of it melts, it will raise the planet\u2019s sea levels by a whopping 24 feet.<\/p>\n<p class=\"\" data-block=\"sciam\/paragraph\">\u201cOur discovery could be key to reducing uncertainties in models of future ice sheet mass balance and sea-level rise,\u201d Born said in the same statement.<\/p>\n<p>It\u2019s Time to Stand Up for Science<\/p>\n<p class=\"subscriptionPleaText--StZo\">If you enjoyed this article, I\u2019d like to ask for your support.
