Myth: Sea level likely will rise 20 feet by the end of the century
Fact: Even the IPCC says the most likely rise will be 17 inches while most climatologists predict a rise of only 7 or 8 inches (about 3 millimeters a year) which has been the rate of sea level rise for the last three centuries.
A court in the United Kingdom determined that Al Gore’s prediction of a 20 foot rise in sea level by the end of the 21st century was not supported by any scientific facts.
Nasa: Historical records may underestimate sea level rise
A new NASA and university study using NASA satellite data finds that tide gauges — the longest and highest-quality records of historical ocean water levels — may have underestimated the amount of global average sea level rise that occurred during the 20th century.
A research team led by Philip Thompson, associate director of the University of Hawaii Sea Level Center in the School of Ocean and Earth Science and Technology, Manoa, evaluated how various processes that cause sea level to change differently in different places may have affected past measurements. The team also included scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California, and Old Dominion University, Norfolk, Virginia.
“It’s not that there’s something wrong with the instruments or the data,” said Thompson, “but for a variety of reasons, sea level does not change at the same pace everywhere at the same time. As it turns out, our best historical sea level records tend to be located where 20th century sea level rise was most likely less than the true global average.”
Small island nations are going to disappear beneath the waves!
Climate alarmists have been making these claims for years, trying to tie them to events like “Superstorm” Sandy, which was below Category 1 hurricane strength when it struck New York City in October 2012, and Typhoon Haiyan, which plowed into the low-lying central Philippines in November 2013.
For alarmists, it does not seem to matter that the strength and frequency of tropical storms have been decreasing in recent years, while the rate of sea level rise has fallen to about seven inches per century. Nor does it seem to matter that the lost lives and property have little to do with the storms’ sheer power. Their destructive impact was caused by their hitting heavily populated areas, where governments had not adequately informed citizens of the size and ferocity of imminent storm surges, too few people had evacuated – and people, buildings and emergency equipment were insufficiently prepared to withstand the furious storm onslaughts.
The alarmist cries are not meant to be honest or factual. They are intended to generate hysterical headlines, public anxiety about climate change, and demands for changes in energy policies and use.
