After the story this morning about the alarmist scientist turned skeptic this story comes as the cherry on top of the AGW sundae:
Faced with the embarrassing fact that sea level is not rising nearly as much as has been predicted, the University of Colorado’s NASA-funded Sea Level Research Group has announced it will begin adding a nonexistent 0.3 millimeters per year to its Global Mean Sea Level Time Series. As a result, alarmists will be able to present sea level charts asserting an accelerating rise in sea level that is not occurring in the real world.
Human civilization readily adapted to the seven inches of sea level rise that occurred during the twentieth century. Alarmists, however, claim global warming will cause sea level to rise much more rapidly during the present century. United Nations Intergovernmental Panel on Climate Change (IPCC) computer models project approximately 15 inches of sea level rise during the 21st century. That’s more than double the sea level rise that occurred during the twentieth century. A more “mainstream” prediction among alarmists is 3 feet of sea level rise this century. Some alarmists have even projected 20 feet of global sea level rise this century.
Satellite measurements, however, show global sea level rose merely 0.83 inches during the first decade of the 21st century (a pace of just 8 inches for the entire century), and has barely risen at all since 2006. This puts alarmists in the embarrassing position of defending predictions that are not coming true in the real world.
So, as with temperature and other data that has been used in this scam, they decided to doctor the numbers.
The NASA-funded group claims glacial melt is removing weight that had been pressing down on land masses, which in turn is causing land mass to rise. This welcome news mitigates sea-level rise from melting glacial ice, meaning sea level will rise less than previously thought. However, it is very inconvenient for alarmist sea level predictions. Therefore, instead of reporting the amount by which sea level is rising in the real world, the Sea Level Research Group has begun adding 0.3 millimeters per year of fictitious sea level rise to “compensate” for rising land mass.
The extra 0.3 millimeters of fictitious sea level rise will add up to 1.2 inches over the course of the 21st century. While this is not monumental in and of itself, it will allow alarmists to paint a dramatically different picture of sea level rise than is occurring in the real world. For example, the current pace of 8 inches of sea level rise for the present century is essentially no different than the 7 inches of sea level rise that occurred last century. However, with an artificially enhanced 9.2 inches of sea level rise, alarmists can claim sea level is rising 31 percent faster than it did last century.
All I hope is Guam doesn’t tip over because of all of this.
If there’s anyone out there that still believes the “science” involved here is valid much less settled, you might want to buy some ocean front property in Idaho.
It’s becoming laughable, isn’t it?

I’ve been an adamant myth buster all my life when it comes to the history of race and racism in our country trying, for years, to clarify which party it was that was on the side of racism and oppression. If one just takes the time to research it, it is there for all to find. Instead, we ended up with a myth.
It appalls me that for years the myth of the right’s racism has gained such purchase in “conventional wisdom” and particularly among American blacks. The belief that it was the Republicans who were against civil rights legislation and were the roadblock to full equality for our black citizens, when in fact it was the Democrats, seems almost accepted as fact now. But I lived and grew up in the South during that time. I know better.
The good news is this video helps to begin the process of dispelling the myth. Pay close attention because it gives you the ground truth of the matter – something, unfortunately, that is very rare these days when it comes to this subject:

David Evans is a scientist. He also has worked in the heart of the AGW machine and consulted full-time for the Australian Greenhouse Office (now the Department of Climate Change) from 1999 to 2005, and part-time 2008 to 2010, modeling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. He has six university degrees, including a PhD in Electrical Engineering from Stanford University. The other day he said:
The debate about global warming has reached ridiculous proportions and is full of micro-thin half-truths and misunderstandings. I am a scientist who was on the carbon gravy train, understands the evidence, was once an alarmist, but am now a skeptic.
And with that he begins a demolition of the theories and methods by which the AGW scare has been foisted on the public. The politics:
The whole idea that carbon dioxide is the main cause of the recent global warming is based on a guess that was proved false by empirical evidence during the 1990s. But the gravy train was too big, with too many jobs, industries, trading profits, political careers, and the possibility of world government and total control riding on the outcome. So rather than admit they were wrong, the governments, and their tame climate scientists, now outrageously maintain the fiction that carbon dioxide is a dangerous pollutant.
He makes clear he understands that CO2 is indeed a "greenhouse gas", and makes the point that if all else was equal then yes, more CO2 in the air should and would mean a warmer planet. But that’s where the current "science" goes off the tracks.
But the issue is not whether carbon dioxide warms the planet, but how much.
Most scientists, on both sides, also agree on how much a given increase in the level of carbon dioxide raises the planet’s temperature, if just the extra carbon dioxide is considered. These calculations come from laboratory experiments; the basic physics have been well known for a century.
The disagreement comes about what happens next.
The planet reacts to that extra carbon dioxide, which changes everything. Most critically, the extra warmth causes more water to evaporate from the oceans. But does the water hang around and increase the height of moist air in the atmosphere, or does it simply create more clouds and rain? Back in 1980, when the carbon dioxide theory started, no one knew. The alarmists guessed that it would increase the height of moist air around the planet, which would warm the planet even further, because the moist air is also a greenhouse gas. [emphasis mine]
But it didn’t increase the height of the moist air around the planet as subsequent studies have shown since that time. However, that theory or premise became the heart of the modeling that was done by the alarmist crowd:
This is the core idea of every official climate model: For each bit of warming due to carbon dioxide, they claim it ends up causing three bits of warming due to the extra moist air. The climate models amplify the carbon dioxide warming by a factor of three — so two-thirds of their projected warming is due to extra moist air (and other factors); only one-third is due to extra carbon dioxide.
That’s the core of the issue. All the disagreements and misunderstandings spring from this. The alarmist case is based on this guess about moisture in the atmosphere, and there is simply no evidence for the amplification that is at the core of their alarmism.
What did they find when they tried to prove this theory?
Weather balloons had been measuring the atmosphere since the 1960s, many thousands of them every year. The climate models all predict that as the planet warms, a hot spot of moist air will develop over the tropics about 10 kilometres up, as the layer of moist air expands upwards into the cool dry air above. During the warming of the late 1970s, ’80s and ’90s, the weather balloons found no hot spot. None at all. Not even a small one. This evidence proves that the climate models are fundamentally flawed, that they greatly overestimate the temperature increases due to carbon dioxide.
This evidence first became clear around the mid-1990s.
Evans is not the first to come to these conclusions. Earlier this year, in a post I highlighted, Richard Lindzen said the very same thing.
For warming since 1979, there is a further problem. The dominant role of cumulus convection in the tropics requires that temperature approximately follow what is called a moist adiabatic profile. This requires that warming in the tropical upper troposphere be 2-3 times greater than at the surface. Indeed, all models do show this, but the data doesn’t and this means that something is wrong with the data. It is well known that above about 2 km altitude, the tropical temperatures are pretty homogeneous in the horizontal so that sampling is not a problem. Below two km (roughly the height of what is referred to as the trade wind inversion), there is much more horizontal variability, and, therefore, there is a profound sampling problem. Under the circumstances, it is reasonable to conclude that the problem resides in the surface data, and that the actual trend at the surface is about 60% too large. Even the claimed trend is larger than what models would have projected but for the inclusion of an arbitrary fudge factor due to aerosol cooling. The discrepancy was reported by Lindzen (2007) and by Douglass et al (2007). Inevitably in climate science, when data conflicts with models, a small coterie of scientists can be counted upon to modify the data.
Evans reaches the natural conclusion – the same conclusion Lindzen reached:
At this point, official “climate science” stopped being a science. In science, empirical evidence always trumps theory, no matter how much you are in love with the theory. If theory and evidence disagree, real scientists scrap the theory. But official climate science ignored the crucial weather balloon evidence, and other subsequent evidence that backs it up, and instead clung to their carbon dioxide theory — that just happens to keep them in well-paying jobs with lavish research grants, and gives great political power to their government masters.
And why will it continue? Again, follow the money:
We are now at an extraordinary juncture. Official climate science, which is funded and directed entirely by government, promotes a theory that is based on a guess about moist air that is now a known falsehood. Governments gleefully accept their advice, because the only ways to curb emissions are to impose taxes and extend government control over all energy use. And to curb emissions on a world scale might even lead to world government — how exciting for the political class!
Indeed. How extraordinarily unexciting for the proletariat who will be the ones stuck with the bill if these governments ever succeed in finding a way to pass the taxes they hope to impose and extend even more government’s control over energy.
While you’re listening to the CEOs of American oil companies being grilled by Congress today, remember all of this. They’re going to try to punish an industry that is vital to our economy and national security, and much of the desire to do that is based on this false “science” that has been ginned up by government itself as an excuse to control more of our energy sector and to pick winners and losers. All based on something which is now demonstrably false.
