Washington, Feb 28: A new study has suggested that Greenland is lagging behind rest of the northern hemisphere's warming trend and that it's bound to catch up soon.
Air temperatures have been rising steadily in the northern half of the planet since about 1975, when scientists think the effects of human-induced global warming began to dominate the climate.
But, Greenland was left behind, perhaps kept cool when dust released from the eruptions of Mount St. Helens, El Chicon and Mt. Pinatubo reduced the amount of sunlight hitting the ice.
Around 1985, the icy island started to thaw, and has continued apace ever since.
