Dramatic melting of sea ice due to global warming is having a major impact on the polar region John Vidal

Arctic sea ice is set to reach its lowest ever recorded extent as early as this weekend, in “dramatic changes� signalling that man-made global warming is having a major impact on the polar region.

WILDLIFE NOW! The consequences of losing the Arctic’s ice coverage for the summer months are expected to be immense. If the white sea ice no longer reflects sunlight back into space, the region can be expected to heat up even more than at present. This could lead to an increase in ocean temperatures with unknown effects on weather systems in northern latitudes. In a statement, a Greenpeace spokesman said: “The disappearing Arctic still serves as a stark warning to us all. Data shows us that the frozen north is teetering on the brink.
