No coal fired power stations. No SUV’s. And they are warning the
planet's atmosphere could have similar levels of the greenhouse
gas within hundreds of years. An international team led by
German scientists and involving University of Queensland
Environmental Geologist Dr Kevin Welsh has found tropical palms
grew on the coast of Antarctica 52 million years ago. At that
warm period in the earth's history, there was twice as much CO2
in the atmosphere as there is now and winter temperatures of 10C
meant Antarctica's 4km thick ice sheet didn't exist. Fancy that,
no ice in Antarctica 52 million years ago. Below is what I wrote
on the same subject for Menzies House on 24th July 2011: Global
warming. Rising sea levels. Massive volcanic activity around the
world. Widespread climate change. It’s not a scene from the
Hollywood disaster film, The Day After Tomorrow, but the Earth
as it appeared during the mid-to late-Cretaceous geological
period, 145 million to 65 million years ago, when the largest
dinosaurs such as Ty
