Greenland's 'dark snow' climate threat worse than thought
Scientists studying the ice in Greenland say one of the factors causing it to melt black soot that absorbs heat from the sun is much worse than they thought, and could contribute to the global rise in sea levels.
Soot and ash from burning coal, wood and dung speed melting of polar ice
Vast stretches of northern Greenland looked like anything but the snowy white North this summer.
That's because huge amounts of soot from the burning of coal, wood, diesel and dung have been deposited in the snow and ice.
Danish-based scientistJason Box says the problem is worse than he ever imagined.
As the snow is darkened by soot, it absorbs more incoming sunlight,causing it to heat upand meltfaster.
"Melting in Greenland will affect sea level rise around the planet," Box says.
