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.He was a co-leader of the only previous expedition to drill into a subglacial Antarctic lake — in 2013 at Lake Whillans, 50 kilometres from Lake Mercer In the case of Lake Mercer, Tulaczyk says, rivers under the ice could have washed the animal carcasses and fungi from the mountains down to the lake.Or the creatures might have frozen onto the bottom of a glacier that dragged them out of the mountains as it advanced.In the meantime, to ensure continued support, we are displaying the site without styles and Java Script.Scientists drilling into a buried Antarctic lake 600 kilometres from the South Pole have found surprising signs of ancient life: the carcasses of tiny animals preserved under a kilometre of ice.
Discovering the animals there was “fully unexpected”, says David Harwood, a micro-palaeontologist at the University of Nebraska-Lincoln who is part of the expedition — known as SALSA (Subglacial Antarctic Lakes Scientific Access).
Summertime temperatures in Antarctica would have been around 5 degrees Celsius (41 degrees Fahrenheit), compared with the -15 to -20 degrees Celsius (5 to -4 degrees Fahrenheit) they are today.
