The latest evaluation of the Arctic sea reveals the ice melted by half in the last three decades and it would be almost free of sea ice by 2040, and no ice by 2070, rising the sea level and submerging many island regions on Earth.
Satellite data collected by the Arctic Monitoring and Assessment Programme found that projections for the melting have been “underestimated” and it has sent out warnings that the Arctic Sea had been warming twice as fast as the rest of the world for the past 50 years.
The report said the region has reached the point of no return for the ice though mitigation of greenhouse gas emissions could help lessen the impact of climate change on the Arctic.
The melting of the Arctic may result in rising incidence of droughts, floods and heat waves, affecting the ocean currents and the winds which in turn affect the monsoon. The end result would be massive draught and decline in food production, besides coastal cities getting submerged due to rise in sea level.
NASA had alredy reported that the sea ice loss in the Arctic was on average 8,300 square miles per year between 1976 and 1996, compared with 19,500 square miles per year between 1996 and 2013.
