Antarctic Climate Change Could Unleash Deadly Tsunamis

Climate change could trigger massive tsunamis in the Southern Ocean by causing underwater landslides in Antarctica, according to a new study. Scientists discovered that during previous periods of global warming, loose sediment layers formed and slipped to send massive tsunami waves racing to the shores of South America, New Zealand and Southeast Asia. As climate change heats the oceans, the researchers think there's a possibility these tsunamis could be unleashed once more. The researchers warn that future landslides, and tsunamis, could happen again as many layers of the sediment are buried beneath the Antarctic seabed, and the glaciers on top of the landmass slowly melt away.
