A massive repository of carbon dioxide under the sea may have started global warming at the end of the last ice age.
Carbon dioxide would have been dissolved in the world's oceans and released at 100,000 year intervals, kick-starting global warming and resulting in a global thaw. The last one could have helped end the last ice age 18,000 years ago.
A huge carbon "burp" from the sea may have ended the last Ice Age 18,000 years ago, scientists believe. The carbon dioxide was locked away in the deep ocean "repository" and as the Earth warmed it was released into the atmosphere causing global warming, it was said.
