“Just how much will the Earth heat up over the next 100 or 200
years? Climate scientists are not able to predict with high
certainty. They have estimated that average global temperatures
will increase by 1.5 to 4.5 degrees Celsius — 2.7 to 8.1 degrees
Fahrenheit — given a doubling of carbon dioxide in the

increase the flood-hazard area in our nation’s coastal floodplain
by 55 percent by 2100.
