London, Nov 26 (ANI): If the current rate of global warming continues, then there will be 'open water at the North Pole in summer within the next few decades', Sir David Attenborough, Britain's greatest broadcasting naturalist, has warned.
The veteran naturalist, who visited the pole for the first time last year, warned that the consequences of melting sea ice would be dire for wildlife and humanity alike, the Independent reports.
Sir David said the implications of Arctic meltwater disrupting the flow of ocean currents, which maintain global climate were 'hard to overstate'.
"The meltwaters from Greenland's glaciers alone could cause a rise in global sea levels of up to half a metre by the end of this century," the paper quoted him, as saying.
"The BBC's Frozen Planet team, filming at both poles for the documentary series, witnessed the melting not just of sea ice but also of freshwater, glacial ice," he added.
Sir David said that if warming leads the Antarctic ice shelves to collapse then vast quantities of land ice and meltwater will slide into the sea and cause a major rise in sea levels around the globe.
"When that will happen and by how much are difficult questions. But with over half of the human population living near the coast, the answers may be only too devastating," he added. (ANI)
