Tomorrow

In anticipation of Dennis Avery's appearance on the NARN broadcast this Saturday I'd like to toss out another brief excerpt from the book he co-wrote with S. Fred Singer entitled "Unstoppable Global Warming: Every 1,500 Years", this one dealing with the scary prediction that cities around the world are in imminent danger of becoming submerged:

Judging from measurements made on corals, sea levels have been rising steadily since the peak of the last Ice Age about 18,000 years ago. The total rise since then has been four hundred feet. The sea levels rose fastest during the Holocene Climate Optimum, when the major ice sheets covering Eurasia and North America melted away. For the last 5,000 years or so, the rate of rise has been about seven inches per century. Tide gauge data from the past century show a rise of about six inches- even after the strong warming period between 1920 and 1940.

When the climate warms, ocean waters expand and glaciers melt, so sea levels rise. But a warmer ocean evaporates more water, some of which ends up as snow and ice on Greenland and on the Antarctic continent, and that makes sea levels fall. More warming and more evaporation are adding ice to the Antarctic ice cap. Thus, there is no reason to expect any big acceleration of sea level increase in the twenty-first century. Researchers say it would take another 7,000 years to melt the West Antarctic Ice Sheet- a small fraction of all the ice- and we're almost sure to get another ice age before then.

Buy the book to read more and be sure to catch Dennis this Saturday at noon on AM1280 The Patriot.
