NASA Scientists Suggest We've Been Underestimating Sea Level Rise (vice.com)

Our current estimate about the global sea level is "way off" according to a new study. The study published in Geophysical Research Letters this month suggests that our historial sea level records have been off by an underestimation of five to 28 percent. From a report on Motherboard: Global sea level, the paper concluded, rose no less than 5.5 inches over the last century, and likely saw an increase of 6.7 inches. The reason for this discrepancy was uncovered by earth scientists at NASA's Jet Propulsion Laboratory and the University of Hawai'i at Manoa. By comparing newer climate models with older sea level measurements, the team discovered that readings from coastal tide gauges may not have been as indicative as we thought. These gauges, located at more than a dozen sites across the Northern Hemisphere, have been a primary data source for estimating sea level changes during the last several decades. "It's not that there's something wrong with the instruments or the data, but for a variety of reasons, sea level does not change at the same pace everywhere at the same time," said Philip Thompson, the study's lead author and associate director of the University of Hawa'i Sea Level Center, in a statement. "As it turns out, our best historical sea level records tend to be located where past sea level rise was most likely less than the true global average."

We want to panic!

We want to panic. The data isn't bad enough, it must be worse! So they hypothesize - with no proof whatsoever - that sea level is rising faster wherever there are no tide gauges.

There is plenty of evidence that this is nonsense. For example, looking at current sea level trends, we do not see a faster rise in the southern hemisphere, even though this is what they say should be happening.

The Jurassic period. O2 in atmosphere was 130% modern levels. CO2 was at 1950ppm, 5-7 times modern levels. The temperature was a whole 3 DEGREES C over modern times! Oh no! The Jurassic DGW, Dinosaurogenic Global Warming, shows that those Dinosaurs - with their Airplanes, SUVs, Coal Fire Plants and Cars and stuff, you know, those Dinosaurs and their DGW destroyed THE WHOLE PLANET!! With their DGW! Look, who wants 26% atmospheric oxygen? More air to breathe? Who wants that? And who wants more CO2 @1950 ppm, you know, to make all those plants and trees convert that CO2 into a higher O2! Who wants that! And we DON'T want the massive biodiversity of the Jurassic, no, we don't want more plants and animals and trees, no.

Any time period the warmunists want to "prove" there is AGW the warmunists just cherry pick ranges. And now I give the warmunists what the need on a silver platter - now they have the perfect example - the Dinosaurs and their horrible DGW (Dinosauric Global Warming) that destroyed the Jurassic... Wait, no, it didn't, it was the best time for life on earth with 1950 ppm atmospheric CO2!

Debt is Wealth. Ignorance is Strength. Freedom is Slavery. War is Peace. Cold is Warm.
