In reply to the discussion: What America will look like once global warming melts the polar ice caps [View all]FarCenter
(19,429 posts)22. It can never happen
Economically recoverable fossil fuels won't last more than several more decades. Emissions will level off and fall as resources exhaust.
The Antarctic ice is very thick and takes a very long time to melt. Thousands of years, as the Washington Post says.
Carbon dioxide does not stay in the atmosphere forever. The estimated half life is about 200 years.
Therefore, the carbon dioxide in the atmosphere will rise, peak and decline before the ice caps are entirely melted and you will never get a 216 foot rise in sea level.
