Evidence from warm past confirms recent IPCC estimates of climate sensitivity

[font size=5]Evidence from warm past confirms recent IPCC estimates of climate sensitivity[/font]
University of Southampton
[font size=3]New evidence showing the level of atmospheric CO2 millions of years ago supports recent climate change predications from the Intergovernmental Panel on Climate Change (IPCC).
A multinational research team, led by scientists at the University of Southampton, has analysed new records showing the CO2 content of the Earth's atmosphere between 2.3 to 3.3 million years ago, over the Pliocene.
During the Pliocene, the Earth was around 2ºC warmer than it is today and atmospheric CO2 levels were around 350-400 parts per million (ppm), similar to the levels reached in recent years.
…
"Today the Earth is still adjusting to the recent rapid rise of CO2 caused by human activities, whereas the longer-term Pliocene records document the full response of CO2-related warming," says Southampton's Dr Gavin Foster, co-author of the study.
