Global sea ice shrinking at unprecedented speeds, warns scientist

From the Independent - climate change experts say the repercussions of warmer sea temperatures are already being felt

Global sea ice is retreating at unprecedented speed with its impact already being felt across the globe, a leading scientist has warned.

While ice in the Arctic is close to record lows, the Antarctic has seen sea ice running at lowest ever levels for this time of year since records began.

Professor Peter Wadhams, head of the polar ocean physics group at Cambridge University, said rates of ice growth in winter had slowed and rising temperatures were causing it to melt faster in the summer, causing a dramatic reduction in area and thickness.

He warned the global repercussions of the reduction of sea ice were already being felt, long before the ice has fully disappeared.

“As the ice area gets less, you're changing the albedo of the earth, which is the fraction of solar radiation that gets reflected straight away back into space, so you're absorbing radiation which warms the earth quicker creating a feedback effect as the ice retreats,” he told The Independent.

“The only secure way of stopping the sea ice to retreat is stopping warming the climate and that is really by reducing our carbon dioxide emissions.”
