Fast forward to September, and the mega-sized iceberg has been dethroned from its No. 1 status as the world’s largest. It now measures just 1,700 square kilometres, or roughly 20 per cent of its original size from the beginning of the year.<\/p>\n","protected":false},"excerpt":{"rendered":"Published on Sep. 16, 2025, 7:20 PM Updated on Sep. 16, 2025, 7:29 PM An iceberg that was…\n","protected":false},"author":2,"featured_media":149200,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[49,48,2848,6093,295,6092,3589,26204,66],"class_list":["post-149199","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-ca","tag-canada","tag-climate","tag-climate-change","tag-environment","tag-global-warming","tag-ice","tag-oceans","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/149199","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=149199"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/149199\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/149200"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=149199"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=149199"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=149199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Iceberg](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2025\/09\/Iceberg_A23a_Getty_Images_Juergen_Brand__2__1942437972-170667a.jpg\"\/)
