Retreating Arctic ice sheets could be uncorking another new source of carbon pollution There' s mounting evidence that ice sheets are letting the lid off a previously unaccounted for source of methane As the Isunnguata Sermia Glacier retreats, organic material trapped under it during its previous expansion is being released as methane. A PATCH of ice in the Arctic, once thought to be the “ last ice area” on the planet to withstand a warming world, has started to break up for the first time in recorded history. Globally, ice melt — from glaciers and ice sheets in the Arctic, in other parts of the world and in Antarctica — was the source of about two- thirds of sea- level between from 1993 to, according to the National Academies of Science, Engineering and Medicine. Thermal expansion accounted for about a third of the rise during that period. Polar Ice Is Disappearing, Setting Off Climate Alarms. The area covered by sea ice in the Arctic hit record lows through the winter of.

Examining land- ice patterns in the Arctic between 19, the study concluded that in the past 47 years, ice melting in the Arctic has contributed 23 millimeters ( nearly an inch) to rising. Each full year, there is a dance involving 2nd year ice, new ice, and an exodus of ice through the Fram Strait.
