New warming study devastates alarmist claims

Written by Michael Bastasch – original source

goreTwo climate scientists skeptical of man-made global warming are closely watching a study they say could be a “death knell” to climate alarmism.

A major scientific study conducted at the University of Reading on the interactions between aerosols and clouds is much weaker than most climate models assume, meaning the planet could warm way less than predicted.

“Currently, details are few, but apparently the results of a major scientific study on the effects of anthropogenic aerosols on clouds are going to have large implications for climate change projections—substantially lowering future temperature rise expectations,” Cato Institute climate scientists Patrick Michaels and Chip Knappenberger wrote in a recent blog post.

Michaels and Knappenberger, both self-described “lukewarmers,” cited a blog post by Reading scientist Dr. Nicolas Bellouin on the preliminary results of his extensive research into this rather vague area of climate science.

Bellouin wrote “there are reasons to expect that aerosol-cloud interactions are weaker than simulated by climate models – and perhaps even weaker than the preliminary… estimate.”

If Bellouin’s preliminary results hold (or are revised downward), that would mean there’s less of a cooling effect from human-created aerosols interacting with clouds, which morph clouds so they bounce incoming solar energy back into space.

“It may be that aerosol-cloud interactions are lost in the noise of natural variability in cloud properties, but for such a large perturbation, the impacts are surprisingly hard to isolate,” Bellouin wrote.

For decades, scientists assumed aerosols — mostly emitted from coal plants, shipping, car travel and other industrial sources — had a sizable cooling effect on the planet, but that might not be the case. More importantly, however, is the fact that if aerosols don’t have much of a cooling effect, the planet is not as sensitive to increases in greenhouse gas emissions. That means less warming.

“Less enhanced cloud cooling means that greenhouse gases have produced less warming than the climate models have determined,” Michaels and Knappenberger wrote.

“Another way to put it is that this new finding implies that the earth’s climate sensitivity—how much the earth’s surface will warm from a doubling of the pre-industrial atmospheric carbon dioxide concentration—is much below that of the average climate model (3.2°C) and near the low end of the IPCC’s 1.5°C to 4.5°C assessed range,” they added.

Michaels and Knappenberger are particularly interested in Bellouin’s work since it seems to support a study from last year by Bjorn Stevens, a scientist at Germany’s Max Planck Institute for Meteorology. It found aerosols had much less of a cooling effect on the planet than assumed by climate models.

Stevens’s study suggested “that aerosol radiative forcing is less negative and more certain than is commonly believed.”

Independent climate researcher Nick Lewis incorporated Stevens’s findings with his own on how much warming people could expect from doubling atmospheric greenhouse gas concentrations. Lewis found the upper bound estimate of climate sensitivity is from 4.5 degrees to 1.8 degrees Celsius.

In layman’s terms, doubling atmospheric concentrations of CO2 from around 400 parts per million today to 800 ppm in the future would cause 4.5 degrees Celsius of warming, based on Intergovernmental Panel on Climate Change (IPCC) climate model data.

Incorporate the Max Planck study results, and warming would only be as high as 1.8 degrees Celsius — less than half of what IPCC originally predicted.

Of course, Michaels and Knappenberger’s theory is not accepted by everybody. Stevens himself challenged their suggestion that climate sensitivity was lower because aerosols had less of a cooling effect on the planet.

“As they stand, the results of this new study seem to confirm the results of an analysis published last year by Bjorn Stevens of the Max-Planck Institute for Meteorology which also showed a much smaller anthropogenic enhancement of the cooling property of clouds,” Michaels and Knappenberger wrote.

Stevens is entitled to his own opinion, not his own results. And now it seems his research is being supported by Bellouin’s work. With less aerosol cooling, climate models could be tweaked to predict less future warming.

“In the end, aerosol-cloud scientists reckon that it will come down to counting how often clouds happen to show strong sensitivity to aerosol perturbations,” Bellouin wrote. “Those discussions leave me with the feeling that such situations occur infrequently, and radiative forcing of aerosol-cloud interactions may need to be revised down to weaker values.”

The Subversion of Science by Green-Left Politics

The Enlightenment
The development of modern science in the late 18th century went hand in hand with the rise of modern industrial capitalism. Its potteries, mines, steam engines, mechanization, and science itself, were all done by private enterprise. The role of government was to enforce patents and maintain a healthy legal and commercial environment.

Nowadays most scientists are paid by the government. What passes for science has largely become taxpayer-funded Environmentalism. Environmentalism has taken over much of science.

Scientists discover, understand and inform.

Environmentalists preach.


“All of us … are borrowing against this Earth in the name of economic growth, accumulating an environmental debt by burning fossil fuels, the consequences of which will be left for our children and grandchildren to bear.” Marcia McNutt – Chief Editor, Science Magazine.

This is preaching. There is no scientific justification for this statement, which was made by the editor of one of the world’s most prestigious science journals. It is a statement of militant Environmentalism, pure and simple. To say that she should have known better is to misunderstand the situation. It would be like saying that the Communists, who controlled big chunks of the Australian trade union movement in the 1950s, “should have known better”. Environmentalists are way ahead of those old Communists; their “Long March through the Institutions” is now a fait accompli.

It works like this: activists use science to push for international action on a science-related issue in an area such as health or environment. Then, an international agreement is established, and the science on which it is has been based becomes institutionalized and funded by government. Time and again, when this happens, “the science” stops being science. This is because the scientists working on the relevant topic start being advocates and stop being researchers. After all, they are now being paid by the bureaucracy to support a particular doctrine, not to discover new stuff.

Real science, which requires a sceptical and innovative frame of mind, then withers on the vine.

Here are some examples:

Radiation Health
In 2012 I received 7000 milli-Sieverts of radiation as treatment for prostate cancer. I found out from the Web that this is twice the fatal dose! I became curious about how I came to survive this assault and I discovered that radiation administered in moderate doses is not cumulative and is not especially harmful. In my case it was definitely beneficial.

But the International Committee for Radiological Protection says otherwise . They say radiation effects are always cumulative and that there is no safe dose: see here about Wade Allison‘s book, Radiation and Reason.

But you can’t be too careful, I hear you say. Well, yes you certainly can be too careful. The Japanese government was too careful when it forcibly relocated 100,000 people following the Fukushima meltdown.

The facts:

Number of deaths: about 1600 people.
Cause of deaths: Suicide mainly.
Number of cases of radiation sickness: 3 people.
Number of deaths caused by radiation: none!
The suicides arose from the social dislocation which occurred when people were compelled to leave their homes and their farms and their jobs and their schools to be relocated to the other side of Japan for reasons of political correctness.

The 1968 London Convention on Ocean Dumping
This forbids the disposal of poisons such as heavy metals in the deep ocean. Hydrothermal vents were discovered in 1977, 9 years after the convention took place. Also known as “black smokers”, they lie on mid-ocean ridges and above volcanic hotspots, 2 to 3 kilometres below the surface of the ocean. Every year they pump into the ocean:

500 tonnes of Arsenic,
1500 tonnes of Lead,
50,000 tonnes of Copper,
140,000 tonnes of Zinc and
many other metals including Uranium and its radioactive daughters.
This has been going on for, perhaps, a billion years or so.

Nature is the biggest polluter of the ocean and the London Convention is a joke. In fact it is worse than a joke because it precludes sensible, practical solutions to important environmental problems. For example, without it we could dispose of radioactive waste in deep ocean trenches where it would be out of harm’s way until it is ultimately subducted under the earth’s crust by geological processes.

Climate Change
The IPCC, the Intergovernmental Panel on Climate Change, is the most egregious example of this science-destroying institutionalization. It is all the more virulent because it feeds into the pre-existing mindset of Left and Green ideologies about “Corporate Greed” and “Mankind wrecking the planet”.

Billions of dollars are being pumped into this. Tens of thousands of climate modellers, their technicians and their computer jocks are the self-righteous recipients. They are not going to give up their funding easily – for them this is the greatest thing since sliced bread and, what is worse, most of them sincerely believe that they are saving the planet.

Over the last 30 years, Climate Science, once a forgotten little wallflower, has become a rock star.

There is really no solid evidence that human activities affect global climate. It is only a theory. Computer models based on this theory have no predictive power; they are complicated curve-fitting exercises and, like all such curve-fitting exercise, they fail catastrophically outside the range of the fit.

On the other hand there is ample evidence that so-called “greenhouse gases” do not affect global temperature to any observable degree (see my UNFCCC Submission to the Federal Government for more detail), viz.:

The observation that the amount of industrial CO2 added to the ocean-atmosphere system since the beginning of the industrial revolution, about 400 Gigatons, is only a tiny fraction of the total amount in the system, 32,000 Gigatons.

The observed rate of decrease in temperature with height, the adiabatic lapse rate, is measured many times a day throughout the world by weather balloons and it fits a simple convective heat transport model of the lower atmosphere. It does not fit a simple radiative heat transport model; there is no blanket of CO2 “holding the heat in”.

Careful comparisons of small changes in global average temperature with variations in atmospheric CO2 concentration indicate that the latter lags the former by about ten months indicating that temperature increases cause CO2 increases and not the other way around.

The global distribution of atmospheric CO2 concentration recently observed by NASA’s Orbiting Carbon Observatory does not support the view that increases in this gas are largely due to Western industrial activity. Rather, the gas appears to emanate from the rice paddies and rain-forests of the Third World (see here and here).

The observation that global average temperature has a variance spectrum which is “red” at every time scale from one year to 100,000 years (i.e. the longer the time scale the bigger the variation). The small variations (~0.8°C) which occurred during the 20th Century are only to be expected. They are random walk excursions. There is nothing to explain. Climate science is like picking patterns in TattsLotto numbers. Meteorologists can predict the weather up to about a week ahead. That’s as good as it gets.

But if you are a scientist who is part of the climate change institution this evidence is all irrelevant. The “Science of Climate Change” was frozen sometime back in the 1990s when the IPCC was first set up. Nowadays it is just a matter of running ever more complex computer simulations and making more “projections” of future climate and its alarming consequences.

And, of course, re-jigging the data so that it fits the models better.

We often hear it said that “97 percent of climate scientists agree …” and so on

Well they would, wouldn’t they.

I am a scientist – I discover things. I discovered cosmic noise absorption pulsations and I discovered the physics underlying the frequency down-shifting of surface gravity waves. I am presently working on a method for distinguishing between cyclical behaviour and random walk excursions in natural time series.

2/3 of Americans refuse to pay one hundred dollars per year, to prevent global warming

dr-evilWritten by Eric Worrall / source:

A recent survey by Rasmussen Reports reveals that 2/3 Americans are unwilling to pay even $100 / annum additional costs to prevent global warming.

According to Rasmussen;

Most voters still aren’t ready to pay much, if anything, to fight global warming, but a slightly higher number are willing to spend more for the cause.

A new Rasmussen Reports national telephone survey finds that 41% of Likely U.S. Voters say they are willing to pay nothing more in higher taxes and utility costs annually to to generate cleaner energy and fight global warming. But that’s down from 48% last August and the lowest level measured in regular tracking since January 2013. Another 24% are willing to spend only $100 more per year, unchanged from earlier surveys. Twenty-six percent (26%) are ready to spend $300 or more a year to combat global warming, with six percent (6%) who are ready to spend at least $1,000 more annually. (To see survey question wording, click here.)

Intriguingly, a lot of people questioned by Rasmussen think global warming is primarily caused by human activity.

To me this suggests 3 possibilities:

Many of the people who are concerned about the climate, don’t think paying more tax will help to cool the planet.
A lot of people who say they are concerned don’t really mean it.
A combination of the above.
However there is good news for people concerned about climate change. If the 26% of Americans willing to spend $300 / annum, and the 6% of Americans willing to spend $1000 / annum, really mean what they say:

26% x 300 million people x $300 + 6% x 300 million people x $1000
= $23 billion + $18 billion
= $41 billion / annum

$41 billion / annum is just under half of what rich countries promised to pay at Copenhagen 2009.

So my good news is, America’s fair share of the $100 billion rich country tithe can be amply covered by the voluntary pledges of people who say they are willing to pay to save the planet – no need to levy taxes on anyone.

Those who believe now have a real opportunity to make a personal difference. Furthermore, I’m happy to volunteer to help coordinate the effort, you can send your cash c/o WUWT. In the next decade it will become more than obvious how effective my secret $410 billion plan to prevent global warming has been – at least it will be, until NOAA revises their figures again.

States Should Defy Unlawful EPA Carbon Dioxide Rules

Originally published in Communities Digital News.

Last June, the Environmental Protection Agency (EPA) proposed its Clean Power Plan as a nationwide regulation to reduce carbon dioxide (CO2) emissions from electrical power plants. Comments to the EPA have now been submitted, and it’s not a surprise that a majority of state governments oppose the plan. In the best interests of US citizens, states should refuse to comply with the proposed EPA Clean Power Plan.

The Clean Power Plan (CPP), more formally named the §111(d) rule, Carbon Pollution Emission Guidelines for Existing Stationary Sources, calls for a 30 percent reduction in power plant emissions by the year 2030. The CPP sets specific CO2 reduction targets for each state, based on four building blocks: 1) improved efficiency of coal-fired power plants, 2) increased use of combined cycle natural gas power plants, 3) increased use of renewable and nuclear energy, and 4) increased energy efficiency by consumers and businesses. But the main thrust of the proposal is the shut-down and replacement of coal-fired power plants, which now provide about 40 percent of US electricity.

There are three major strikes against the Clean Power Plan. First, the authority assumed by the CPP is not granted to the EPA by the laws of the United States. Second, efforts to try to implement the CPP will degrade the finest electrical system in the world, hurting consumers and businesses. Third, if implemented, the CPP will not have a measurable effect on global warming.

The Clean Air Act of 1970 authorized the establishment of state and federal regulations to control air pollution, and established the EPA to implement requirements of the act. The Clean Air Act and its amendments of 1977 and 1990 authorize the EPA to establish national ambient pollution standards and to control pollution levels from individual facilities, but not to regulate state electricity markets. A September 2014 letter from 15 state governors stated that the EPA’s Clean Power Plan proposal, “not only exceeds the scope of federal law, but also, in some cases, directly conflicts with established state law.”

“Snowmageddon” threatens Massachusetts global warming forum

Massachusetts state house snowThe record-shattering snow that has shut down Boston’s public transit system threatens to white out a global warming forum organized by Massachusetts Senate President Stanley Rosenberg (D, Amherst).

Rosenberg scheduled the forum for 1 PM Tuesday beneath the golden dome of the Massachusetts State House in Boston.

‘Rosenberg said the state has already seen how climate change is manifesting itself in the state with stronger storms, extreme temperatures, and a changing environment.’

Massachusetts Governor Charlie Baker has declared a state of snow emergency and has shut down “non-essential” state services and buildings in four counties on Tuesday, including Suffolk County where the Boston global warming forum is scheduled to take place.

Inconveniently, Boston is in the midst of its snowiest winter in a century. The city hit 73″ inches of snow on Monday placing this year on the top ten list for snowiest winters on record, surpassing the 72.9″ recorded during the winter of 1903-1904.
