While
rapid rise in sea levels pose a threat to people and coastal habitats, it could be beneficial to other valuable residents in the planet, particularly coral reefs.
Studies of sea level and temperatures over the past million years suggest that each 1 °C rise in the global mean temperature eventually leads to a 20 -
metre rise in sea level.
But what about the risk that a city might not even exist in a few years, the victim of catastrophic
rises in sea level due to global warming?
These problems range from the disruption of global weather patterns and a
global rise in sea level to adverse impacts on human health, agriculture, and animal and plant populations.
In fact, the
total rise in sea level that was due mainly to shrinking ice sheets was ~ 120 meters over the past 17,000 years.
While the shipping industry — which now has easy northern access between the Atlantic and Pacific oceans — may be cheering this «natural» development, scientists worry about the impact of the resulting
rise in sea levels around the world.
The data allowed them to calculate the redistribution of mass on Earth's surface due to the melting of the Greenland and Antarctic ice sheets and mountain glaciers, and the
resulting rise in sea level.
Corell noted that the projected
rise in sea level during this century of 18 — 59 centimeters (7 — 23 inches) by the Intergovernmental Panel on Climate Change was based on data that were two years old.
Quality Coverage Finally, major media get good marks in a forthcoming paper assessing 20 years of news coverage of the
projected rise in sea levels in a warming world by Ursula Rick, Maxwell Boykoff (of «balance as bias» fame) and Roger A. Pielke Jr., all at the University of Colorado.
For instance, the report notes that there are 22 wastewater treatment plants on the Bay Area's shoreline that are vulnerable to a 55 -
inch rise in sea level by 2100, which is on the upper end of such predictions.
If you truly believe there is a
significant rise in sea level (and compensation required by «glacial rebound») then certainly these classified datasets should show the impact of 50 years of warming.
George @ 277, the tide gauge records collated by NOAA, for The Battery, on Manhattan, show a 400
mm rise in sea level during the past 160 years.
With both West and East Antarctica affected by the change in currents, in the future
abrupt rises in sea level become more likely.
