Rising Sea Levels And National Security

In this second of the three aspects of climate change that threaten national security, Admiral Titley discusses rising sea levels. The pace of change is gradual. The magnitude of change is small. And that allows deniers respite from reality. But the environmental effects, though local, will be catastrophic.

Glaciology combines the science of numerous disciplines. Deniers want to use simple observations of surface ice to support their conclusions. Unfortunately, it is not so simple. Ocean water is warming and with that the relationships of the glaciers to the earth on which they were grounded. Many are now afloat. We are not so certain what this means. What we know is that there is data to support the projection of a one meter sea level rise by 2100; and that is conservative.
