Sea Levels Rising 2.5 Times Faster Due To Melting Of Ice Sheets: UN

Since 2005 seas have risen 2.5 times faster than during the 20th century mainly due to melting of ice sheets, and will likely jump four-fold again by 2100 if carbon emissions continue unabated, the UN warned on Wednesday.

But capping global warming at under two degrees Celsius -- the cornerstone goal of the Paris climate treaty -- could stabilize the rate of increase and hold the line at a meter above today's watermark, even two centuries from now, the Intergovernmental Panel on Climate Change (IPCC) said.
