Scientists warn climate crisis could trigger giant killer tsunamis resulting in huge loss of life [Video]

Giant underwater 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 New 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 …
