The polar ice in the Arctic is at an all-time low. We have a 3rd or 4th – In Summer there is generally about the size of the United States (lower 48 states).
Have lost a volume equal to half of United States in terms of summer ice cover! We may come to a point in our lifetimes when Arctic may not even have ice in summers – in this decade or next one at the latest! Not just that but the ice there is also thinning. The global impact of these changes on environment will be dramatic!
