Plants Need CO2 To GrowMarch 26, 2012
Is this finally proof we're NOT causing global warming?

Is this finally proof we're NOT causing global warming? The whole of the Earth heated up in medieval times without human CO2 emissions, says new study.
Current theories of the causes and impact of global warming have been thrown into question by a new study which shows that during medieval times areas as far apart as Europe and Antarctica both warmed up.
A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that the 'Medieval Warm Period' approximately 500 to 1,000 years ago wasn't just confined to Europe.
At present the Intergovernmental Panel on Climate Change (IPCC) argues that the Medieval Warm Period was confined to Europe.
However, Professor Lu has shown that this the Medieval Warm Period had a much broader reach - and the evidence lies with a rare mineral called ikaite, which forms in cold waters.
Lu says that his research has no direct bearing on the current climate, and points out that his research is restricted to one area in Antarctica, and is not in itself proof that the whole Earth warmed up.
