What looked like worms were actually the tendrils of a land-dwelling plant or fungus.
Or the creatures might have frozen onto the bottom of a glacier that dragged them out of the mountains as it advanced.Scientists from across the UK came together in a Royal Meteorological Society meeting on April 3 to discuss the most recent research in climate change, and how our distant past may soon come back to repeat itself.One of the researchers, Jane Francis from the British Antarctic Survey, based her analysis on a finding of plant fossils and sedimentary records dating from the Pliocene epoch, between 5.3 million and 2.6 million years ago.. I call them the last forests of Antarctica.""They were growing at 400 ppm [parts-per-million] CO2, so this may be where we are going back to, with ice sheets melting at times, which may allow plants to colonise again."Last year the amount of carbon dioxide in our atmosphere reached 410 ppm, thought to be the highest level in the last 800,000 years.Drastic steps are needed to stop that from happening, otherwise we'll be back to the Pliocene era – or maybe even further.While some aspects of the changing climate are now inevitable, a study earlier this year showed there could still be a chance to limit temperature rises, although the window is closing fast.
