Giant under water landslides induced in Antarctica by the climate crisis might lead to tsunami waves with the potential to cause a “substantial loss of life far from their origin”, according to a new study. 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 Nature Communications, scientists found extensive layers of weak, fossilised and biologically rich sediment hundreds of metres beneath the seafloor.

Interesting is the chart provided by Climatologist Cliff Harris and Meteorologist Randy Mann.
They said: We should remember, that the Earth’s coldest periods have usually followed excessive warmth. Such was the case when our planet moved from the Medieval Warm Period between 900 and 1300 A.D. to the sudden “Little Ice Age,” which peaked in the 17th Century. Since 2,500 B.C., it’s estimated that there have been over 70 major climate changes worldwide, including two major changes in just the past 50 years. In terms of upcoming cooling and warming periods, only time will tell.
