Sea Level

The Polar Ice Melt Myth

According to the National Snow and Ice Data Center (nsidc.org), ice currently covers 6 million square miles, or one tenth the Land area on Earth, about the area of South America. Floating ice, or Sea Ice, alternately called Pack Ice at the North and South Poles covers 6% of the ocean’s surface (nsidc.org), an area similar to North America. The most important measure of ice is its thickness. The United States Geologic Survey estimates the total ice on Earth weighs 28 million Gigatons(a billion tons). Antarctica and Greenland combined represent 99% of all ice on Earth. The remaining one per cent is in glaciers, ice sheets and sea ice. Antarctica can exceed 3 miles in thickness and Greenland one mile. If they were to melt sea level would indeed rise over 200 feet, but not even the most radical alarmists suggest that possibility arising due to the use of fossil fuels. However the ice that flows off of the Antarctic and Greenland called shelf ice represents only half a percent of all the Earth’s ice and which if melted would raise sea level only 14 inches, (nsidc.com).

By Willis Eschenbach – Re-Blogged From WUWT

Over in the Tweeterverse, I said I wasn’t a denier, and I challenged folks to point out what they think I deny. Brandon R. Gates took up the challenge by claiming that I denied that sea level rise is accelerating. I replied:

Brandon, IF such acceleration exists it is meaninglessly tiny. I can’t find any statistically significant evidence that it is real. HOWEVER, I don’t “deny” a damn thing. I just disagree about the statistics.

Brandon replied:

> IF such acceleration exists

It’s there, Willis. And you’ve been shown.

> it is meaninglessly tiny

When you have a better model for how climate works, then you can talk to me about relative magnitudes of effects.

Thirty Years of Error? In 1988, the Intergovernmental Panel on Climate Change (IPCC) was created by the UN under the World Meteorological Organization (WMO) and the United Nations Environmental Programme (UNEP) from a resolution by the UN General Assembly to address possible future, human-induced, climate change. The reports of the IPCC support the United Nations Framework Convention on Climate Change (UNFCCC). The objective of the UNFCCC is “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.” [Boldface added.]

Sea Level Speculation Threatens Property Owners

Pacifica California, just south of San Francisco, is my adopted hometown of 25 years. It has garnered national attention as an icon of dangerous sea level rise as eroding cliffs dangled homes over ocean bluffs (discussed in a WUWT post a few years ago). To the delight of property owners and the dismay of environmental extremists, I became a member of Pacifica’s Community Working Group on Sea Level Rise. Governor Jerry Brown’s California Coastal Commission has advised coastal cities to consider that by the year 2100 we should expect a range of sea level rise from 3 to 10 feet due to climate change. Based on such predictions the city will map flood zones, and properties in those zones could suffer from Coastal Commission restrictions that will devalue their property.

Sea Level Rise – What is Measured? Last week’s TWTW had an interview with Richard Lindzen a with statement questioned by some readers. The paragraph with the statement is:

“Since 1979 we have been able to measure sea level itself with satellites. However, the accuracy of such measurements depends critically on such factors as the precise shape of the earth. While the satellites show slightly greater rates of sea level rise, the inaccuracy of the measurement renders the difference uncertain. What the proponents of alarm have done is to accept the tide gauge data until 1979, but assume that the satellite data is correct after that date, and that the difference in rates constitutes ‘acceleration.’ They then assume acceleration will continue leading to large sea level rises by the end of this century. It is hard to imagine that such illogical arguments would be tolerated in other fields.” [Boldface added]

Constant, Not Accelerating: On May 16, SEPP Chairman emeritus S. Fred Singer had an essay in the Wall Street Journal explaining why there is little humanity and governments can do to stop the constant rate of sea level rise. Unfortunately, in the print edition, the sentence “But there is also good data showing sea levels are in fact rising at a constant rate,” was muddled into reading “But there is also good data showing sea levels are in fact rising at an accelerating rate.” [Boldface added]. The error was corrected in the online editions. The central issue of Singer’s essay is” that sea-level rise does not depend on the use of fossil fuels.”
