Global Warming May Bring Tsunami And Quakes: Scientists

Quakes, volcanic eruptions, giant landslides and tsunamis may become more frequent as global warming changes the earth’s crust, scientists said on Wednesday.

Climate-linked geological changes may also trigger “methane burps,” the release of a potent greenhouse gas, currently stored in solid form under melting permafrost and the seabed, in quantities greater than all the carbon dioxide (CO2) in our air today.
“Climate change doesn’t just affect the atmosphere and the oceans but the earth’s crust as well. The whole earth is an interactive system,” Professor Bill McGuire of University College London told Reuters, at the first major conference of scientists researching the changing climate’s effects on geological hazards.

“In the political community people are almost completely unaware of any geological aspects to climate change.”

The vulcanologists, seismologists, glaciologists, climatologists and landslide experts at the meeting have looked to the past to try to predict future changes, particularly to climate upheaval at the end of the last ice age, some 12,000 years ago.

“When the ice is lost, the earth’s crust bounces back up again and that triggers earthquakes, which trigger submarine landslides, which cause tsunamis,” said McGuire, who organized the three-day conference.
