Study explains early warming of West Antarctica at end of last ice age
August 14, 2013
West Antarctica began emerging from the last ice age about 22,000 years ago--well before other regions of Antarctica and the rest of the world. Scientists say that changes in the amount of solar energy triggered the warming of West Antarctica and that the subsequent release of carbon dioxide from the Southern Ocean amplified the effect and resulted in warming on a global scale, eventually ending the ice age.
