The loss of Antarctic ice

Antarctica has lost 147,000 million tons of ice per year since 2003.

As ice melts in Antarctica, the weight of the ice falls and NASA’s satellites detect this. Here is how the weight of Antarctic ice has dropped since 2002.

This graph shows the movement over time of the mass of Antarctic ice measured in thousands of millions of tonnes (gigatonnes or Gt).

The ice levels move up and down with the seasons – but overall there is a downward trend.


A section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline. This melting would raise global sea levels by 1.2 metres. NASA: News Release: 12 May 2014

If the entire Antarctic Ice Sheet melted, sea level would rise by about 60 meters.

Substantial melting of the Antarctic ice might take hundreds of years, but would we want our descendants to cope with the flooding of most major cities in the world?

The Antarctic is losing sea-ice at record levels.

It is not sustainable for us to have 147,000 million tons of Antarctic ice melting each year and significant areas of the ice sheet in an irreversible state of decline.
