AAD/Woods Hole; Rapid, Significant Changes At Base Of Antarctic Food Chain; 8/21 Hottest Days In '13
Major changes to the food chain, weather and landscape of Antarctica have provided stark evidence of the impact of global warming, a report on a polar expedition has revealed.
The preliminary report on the research by scientists from the Australian Antarctic Division and the Woods Hole Oceanographic Institute near Boston suggest significant changes at the lowest level of the food chain, a vital source of sustenance for seabirds, seals and whales.
The Climate Commission recently said there was evidence natural events were being influenced by climate change as greenhouse gases accumulated and trapped measurable amounts of extra energy in the atmosphere and oceans.
Eight of the 21 hottest days on record have occurred so far this year. The expedition senior scientist of the Australian Antarctic Division, Steve Nicol, said in 25 years of surveying Antarctica, this was the first time he had experienced rain.
