Today I saw some scary headlines. I post them up along with snippets of the stories. First, from the BBC:
Earth’s great ice sheets, Greenland and Antarctica, are now losing mass six times faster than they were in the 1990s thanks to warming conditions.
“That’s not a good news story,” said Prof Andrew Shepherd from the University of Leeds in the UK.
Next, from the NASA Jet Propulsion Laboratory (JPL)

How do we measure success in helping people understand the climate issue? I don’t think we can measure it by unique visits to WUWT or various videos that many of us know well. But they simply attract the same audience over and over. I think the only way to measure success is by somehow measuring minds changed. This is a quick announcement of a new video I recently released, my philosophy on how to change minds, and a request from the community to help me with some data science.
My name is David Siegel. In 1991, I wrote a book explaining how the greenhouse effect worked and how we have to cut back on CO2 emissions or suffer dire consequences. Then, in about 2014, a partner at a green fund told me “the science is settled.” That prompted me to revisit the subject, and I was surprised to find that the data didn’t support the “common wisdom” that I had believed for so long. So I started reading papers, blogs, and web sites like WUWT.

After considering the tide gauge records around Fairbourne in my last post, I wanted to look at a larger picture. Remember that we’ve been repeatedly told that acceleration in sea level rise is not just forecast, it’s actually occurring. I wrote about some of these claims in my post entitled “Accelerating The Acceleration“. Plus we’ve been deluged, if you’ll excuse the word, with endless cartoons and memes and movies and earnest predictions about the Statue of Liberty going underwater, cities being drowned, islands being overtopped by the sea, and the like. And not only that, but we’re assured that we can see and measure the acceleration in both the tide gauge and the satellite sea-level records.
So I went to get the satellite sea-level records from the University of Colorado. But when I plotted them up, I realized that they stopped in 2018. I couldn’t find anything on their website that explained why. Here’s their data.
Figure 1. University of Colorado sea-level record. Note that it is a splice of four satellite datasets that all seem to be in quite good agreement.

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).

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.]

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.
