Mysteriously warm times in Antarctica:

"The findings, reported this week by scientists from the British Antarctic Survey (BAS), the Open University and University of Bristol in the journal Nature could help us understand more about rapid Antarctic climate changes. Previous analysis of ice cores has shown that the climate consists of ice ages and warmer interglacial periods roughly every 100,000 years. This new investigation shows temperature 'spikes' within some of the interglacial periods over the last 340,000 years. 

This suggests Antarctic temperature shows a high level of sensitivity to greenhouse gases at levels similar to those found today. Lead author Louise Sime of British Antarctic Survey said, 'We didn't expect to see such warm temperatures, and we don't yet know in detail what caused them. But they indicate that Antarctica's climate may have undergone rapid shifts during past periods of high CO2.' During the last warm period, about 125,000 years ago, sea level was around 5 metres higher than today."

PS: Sobre o mesmo ver: Rising CO2 could cause catastrophic sea level rise finds Antarctic study| Climate Ark: "The British Antarctic Survey found that during past periods of high carbon dioxide, temperatures in Antarctica were up to 6C above current levels. This could cause a sea level rise of up six metres, threatening coastal cities like London, New York and San Francisco. It is the latest research to warn of the consequences of increased greenhouse gases on the Earth's climate. Yesterday a study warned that carbon dioxide produced by man is now rising at record rates putting the world on a pathway for a 6C rise in temperature."
