The mass extinction would be caused primarily by heat stress as a result of greater volcanic activity that would put twice as much carbon dioxide into the atmosphere as current levels, an older sun that would emit more radiation and the extent of inland deserts in the tropics.<\/p>\n<p>Using a UK Met Office climate model and the University of Bristol supercomputer, the simulation also provided tectonic clues to past extinction events and data that could be of use to astronomers looking for other habitable planets. In the era of Pangea Ultima, the temperature extremes are expected to be dramatic, with more humidity than now along the coasts and extremely arid conditions in the vast inland deserts. In this world, global temperatures could rise 15C (and up to 30C on land) above pre-industrial levels, which would return the world to the extreme heat it last went through in the Permian\u2013Triassic era, 260m years ago, when more than 90% of species were eradicated. Protracted periods of heat in excess of 40C would be beyond the tolerance levels of many life forms.<\/p>\n<p>In addition to the direct impacts of heat, there would be severe food supply problems due to a collapse of vegetation. The paper notes that most plants become stressed at temperatures over 40C and break down completely if exposed to 60C for protracted periods. The authors acknowledge their prediction has a high level of uncertainty due to the ultra-long-term timeframe, but they hope the study, which was initiated during the pandemic lockdown, will provide useful insights into past mass extinction events and the possible habitability of other planets.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.theguardian.com\/science\/2023\/sep\/25\/supercontinent-could-make-earth-uninhabitable-in-250m-years-study-predicts\">Guardian<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/4-403\/\">\u2018Supercontinent\u2019 could make Earth uninhabitable in 250m years, study predicts<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[613,575,1683,792],"class_list":["post-117176","post","type-post","status-publish","format-standard","hentry","category-news","tag-earth","tag-environmental-news-en","tag-heating","tag-study"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/117176","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=117176"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/117176\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=117176"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=117176"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=117176"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
