The good news was announced in the most recent report on the subject released by the World Meteorological Organization (WMO) and four other institutions in January. According to the document, if the world maintains its ban on chlorofluorocarbons (CFCs)\u2014volatile compounds that destroy ozone in the atmosphere\u2014this thin layer of gas should be recovered in most parts of the planet by 2040. Close to the poles, where it is less dense, it will take longer to recuperate: the hole in the ozone layer at the North Pole is expected to close in around 2045 and in Antarctica at the South Pole by 2066. The ozone layer is being restored thanks to a global effort to stop the use of CFCs, which for decades were used in the production of insulating foams or as refrigerant gases and propellants in aerosol sprays. They were banned by the 1989 Montreal Protocol, but emissions have been detected in parts of China in the past decade. According to the latest report, these emissions have dropped sharply.<\/p>\n","protected":false},"excerpt":{"rendered":"Ozone layer is recovering and should be restored within a few decades","protected":false},"author":475,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[217,200],"coauthors":[785],"class_list":["post-477718","post","type-post","status-publish","format-standard","hentry","category-notes","tag-climate","tag-environment"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/477718","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=477718"}],"version-history":[{"count":3,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/477718\/revisions"}],"predecessor-version":[{"id":477736,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/477718\/revisions\/477736"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=477718"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=477718"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=477718"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=477718"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
