Underwater landslides are global hazards that can displace large volumes of sediment and generate killer tsunamis. For instance, a submarine landslide near Papua Nwe Guinea in 1998 generated tsunami waves that killed 2,200 people. Researchers, including those from the University of Plymouth in the US, discovered that between 3 and 15 million years ago, during a past period of global heating, loose sediment layers slipped in Antarctica, triggering giant tsunamis that ravaged the shores of New Zealand, southeast Asia and South America. In the new study, published recently in the journal&nbsp;<em>Nature Communications<\/em>, scientists found extensive layers of weak, fossilised and biologically rich sediment hundreds of metres beneath the seafloor. <span style=\"color: #0000ff;\"><strong><em>Read more at:<\/em><\/strong> <\/span><a href=\"https:\/\/www.independent.co.uk\/climate-change\/news\/tsunami-antarctica-landslide-climate-change-b2345627.html\">Scientists warn climate crisis could trigger giant killer tsunamis resulting in \u2018huge loss of life\u2019 | The Independent<\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-10087 alignleft\" src=\"http:\/\/www.waponline.it\/wp-content\/uploads\/2023\/07\/Global-temperatures-300x216.jpg\" alt=\"\" width=\"300\" height=\"216\" srcset=\"http:\/\/www.waponline.it\/wp-content\/uploads\/2023\/07\/Global-temperatures-300x216.jpg 300w, http:\/\/www.waponline.it\/wp-content\/uploads\/2023\/07\/Global-temperatures-50x36.jpg 50w, http:\/\/www.waponline.it\/wp-content\/uploads\/2023\/07\/Global-temperatures.jpg 720w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>Interesting is the chart provided by <em><strong><span style=\"color: #0000ff;\">Climatologist&nbsp; Cliff Harris<\/span><\/strong><\/em> and Meteorologist <em><span style=\"color: #0000ff;\"><strong>Randy Mann<\/strong><\/span><\/em>.<br \/>\nThey said: &nbsp;We should remember, that the Earth&#8217;s coldest periods have usually followed excessive warmth.
