Antarctica was home to rainforests 90 million years ago: Study



Researchers have unearthed evidence of rainforests near the South Pole 90 million years ago, a finding which suggests that the climate at this time was exceptionally warm with a higher level of carbon dioxide in the atmosphere than previously thought. The scientists, including those from Imperial College London in the UK, discovered forest soil pertaining to a time between 145 and 66 million years ago within 900 kilometres of the South Pole. In the study, published in the journal Nature, they analysed preserved roots, pollen, and spores from this soil, and showed that the world at that time -- the Cretaceous period -- was a lot warmer than previously thought.
