Reference: Antarctica ice collapses were regular, Bangkok Post, March 19, 2009

New data from the Ross ice shelf show that the West Antarctic ice shelf collapses every 40,000 years or so and that this process has been regular feature of this ice shelf for millions of years (Antarctica ice collapses were regular, Bangkok Post, March 19, 2009). These melting episodes can raise the sea level by as much as 5 meters but the process takes a thousand years or more. Clearly, this phenomeon cannot be linked to human activity and it does not present grave and imminent threat to humanity.
