It was the beginning of a new glacial period, more conversationally known as the next ice age—but by the 1960s, summer temperatures were already so high that the ice sheet started to shrink. In other words, global warming ended a period of glaciation that had already begun.","pubDate":"Thu, 22 Oct 2026 14:00:10 EDT","url":"https://phys.org/news/2026-10-global-halted-emerging-ice-age.html"},"indexado":"2026-10-22T18:02:17.964Z"}}
