Squidly (10:16:07) :
Assumptions are BAD! Never assume anything!
Assumptions are good, even vital, as long as you know what they are and that they are assumptions. We may, for example, say “assuming that General Relativity holds, we calculate such and such..”. Nothing wrong with that. Or an example closer to my own field: “assuming that the solar polar fields control the size of the next sunspot cycle, we predict that it will be a small cycle”. The outcome determines whether the assumption was reasonable and whether we should use the assumption again later.

Politics is emotional and local (as in each indivual).
Peaple, (individuals) respond to significant emotional events.
Undesired events are met with;
A. Denial
B. Anger
C. Negotiation
and finally,
D. Acceptance
Should Cimate Change result in Cooling, acceptance will occur when peaple find themselves cold, wet, and hungry.
The more dangerous of outcomes IMO.

Pamela’s Tank remark has some validity.But we don’t need a Tank but a good
anti tank weapon like a Bazooka,shaped charge, a track bustin’ landmine.
The unexpected can get results-like this blog…

Margaret Thatcher said: “Socialists have always spent much of their time seeking new titles for their beliefs, because the old versions so quickly become outdated and discredited.”
Socialist = AGWer = Sci-babble
What could be more timely, now that AGWers are searching for new labels for the bottles of snake oil.
Pamela Gray is correct regarding seemingly plausible nature of AGW. Although you can’t kill a tank with a hammer, you can kill it with a Molotov cocktail.
It is time for AGW opponents to make their rhetoric incendiary. Stop being nice, be blunt. No more platitudes, say what you intend without any gift wrapping,e.g. the claim that CO2 is a pollutant is a lie, not a mistake or misapprehension. Mocking helps too.

Hi,

Mr Watts and the Commenters. I’d like you to focus your attention to truly intellectual adventure, me the layman, have found in Mr Bob Tisdale’s text:
“RSS MSU TLT Time-Latitude Plots…” (…Show Climate Responses That Cannot Be Easily Illustrated With Time-Series Graphs Alone)

“…global warming/climate change has developed so much momentum that it has a life of its own – quite removed from science.”
Well said!
The mainstream media doesn’t report on the science but rather the alarmist claims of negative impacts. If you only read the mainstream media accounts you would have to come to the overwhelming conclusion that any and all warming has only negative impacts on man and the planet. But I keep reminding people that a little warming is MUCH better than a little cooling!

OT: Editorial: Cooling down with global-warming data
U.S. and world temperature records are compromised by monitoring station errors.
An Orange County Register editorial
http://www.ocregister.com/articles/temperature-stations-global-2433763-heat-watts
If fighting global warming may cost the economy $9.6 trillion and more than 1 million lost jobs by 2035, as the Heritage Foundation forecasts, it’d be a good idea to be sure there’s a sound basis before making such a massive sacrifice.
We’ve noted before that climate change is occurring as it always has, but the claim that man-made greenhouse gases will cause catastrophic temperature increases is based on questionable science and projections. Man’s contribution to greenhouse gases is minuscule. There are some theories but no convincing proof that increased emissions cause increased temperature.
Now another serious doubt has been raised concerning how much of the 1-degree centigrade increase over the past century allegedly caused by escalating emissions has even occurred.
“We can’t know for sure if global warming is a problem if we can’t trust the data,” said Anthony Watts, veteran broadcast meteorologist, who for three years organized an extensive review of official ground temperature monitoring stations, in conjunction with Dr. Roger Pielke Sr., senior research scientist at the Cooperative Institute for Research in Environmental Sciences and professor emeritus of the Department of Atmospheric Science at the University of Colorado.
The study, recently published by the free-market Heartland Institute, inspected 860 of the 1,221 U.S. ground stations that gauge temperature changes. The findings were alarming.
They found 89 percent of stations “fail to meet the National Weather Service’s own siting requirements” that say stations must be located at least 100 feet from artificial heat sources.
“We found stations located next to the exhaust fans of air conditioning units, surrounded by asphalt parking lots and roads, on blistering hot rooftops and near sidewalks and buildings that absorb and radiate heat,” Mr. Watts reported.
Many stations also had added more sensitive measuring devices, heat-generating radio transmission devices and even latex paint to replace original whitewash, resulting in greater heat retention and reflection.
At one location, Mr. Watts said when he “stood next to the temperature sensor, I could feel warm exhaust air from the nearby cell phone tower equipment sheds blowing past me! I realized this official thermometer was recording the temperature of a hot zone . . . and other biasing influences including buildings, air conditioner vents and masonry.”
These influences produce readings higher than actual ambient temperatures, Mr. Watts said. Moreover, the research revealed “major gaps in the data record that were filled in with data from nearby sites, a practice that propagates and compounds errors.”
These inflated, error-prone, tinkered-with temperature recordings are one of several measurements cited by the U.N.’s Intergovernmental Panel on Climate Change as evidence man-made global warming is a threat. But the Heartland study concluded, “The U.S. temperature record is unreliable. And since the U.S. record is thought to be ‘the best in the world,’ it follows that the global database is likely similarly compromised and unreliable.”
Before devastating the economy to fix a problem that may not exist, we ought to get the numbers right.

Pamela Gray (07:16:02) :
That is not how science is supposed to work. You don’t have to have an alternate hypothesis to falsify the AGW hypothesis. You just need to show how the AGW hypothesis does not match actual observations.
The AGW-mongers and the MSM are trying to mislead people when they insist otherwise.

Here’s another AGW biased prediction, the NCDC forecasts a sizzling summer for much of the U.S according to USA today with the only truly cool spot being in the north central region. Then I look as WXmaps today and the forecast anomaly for the US over the next week and seeing a lot of average to below normal anomalies forecast for the East and what doesn’t look like sizzling to me in the West, the only real ‘hot’ spot anomaly-wise in North America is Alaska with cooler than normal temps. forecast for much of Canada, no doubt the media will just want to focus on there right now and not much of anywhere else in the country.
Sites like IceAgeNow often show coldwave stories to remedy burnout from CNN and friends feeding heatwave stories to you, you’d go to both (and then there’s this site) if you want both sides of the coin.

One can reasonably expect that opportunism of the weak will lead to efforts to alter the data (though the results presented here have survived several alterations of the data already).
This is it in a nutshell. Sensor data and sensor
performance, which affects data, can be manipulated.
Given the amount of money involved, agenda driven
science, and a willing media, how can you how can
defend against it? Ridicule! Every time one of the pillars
of their argument is destroyed, the people, media and
politicians, must be crushed as well. Anything less, will
have the effect of complicity. I know this sounds harsh,
but this is a high stakes game where our freedom and
way of life is in the balance. They are not going to control
my life….Yours?

Be very careful in quoting Margaret Thatcher in support of your anti-AGW stance. If you do some research, you will find that it was she who turned AGW into an international policy issue! For example Google “Margaret Thatcher Global Warming” and you will find “Global Warming: – How It All Began” by
Richard Courtney:
“Then, in 1979, Mrs Margaret Thatcher (now Lady Thatcher) became Prime Minister of the UK, and she elevated the hypothesis to the status of a major international policy issue.”
Can we get away from the conservative versus liberal US dogfight and stick to the science? As a liberal UK citizen with a scientific education I am a confirmed AGW sceptic who is delighted with WUWT’s excellent work!

Yes. The money. Consensus. Groupthink. Mass hysteria. The Madness of Crowds. Versus the truth.
Scientists, the media and politicians. The three forces in play if you include the totality of activism within the political set and disregard those who fall into more than one, such as celebrities, the Governor of California and the odd (astro)physicist.
Truth. The media don’t know the meaning of the word. They get paid irrespective of what science or politics says or does. Politicians are “economical” with it and exist solely to play with it, fix it around policy and spin it for their “backers” and the media.
The modern-day scientist looks at his fellow players and something leaps out of the morass and hits them in the eye. Lies of Omission, derailment, confusion and obfuscation pay. Well. You too can aspire to the accumulation of wealth beyond the dreams of ancient kings. All you have to do is as thy peers do. Tell a few porkies, fibs and white lies. Exaggerate a little. Smudge some paperwork. Smear a little data here and there. Take a seat guy. Look over there….
Oh so human. Predictable. Tragic.
On the whole, climate science is young. Climate scientists are young. Climate scientists wish to feed and clothe their young. They imagine sending their young to the very institutions that produced them. Do not be surprised when they wish to defend their young, or their ability to provide for them.

Several posts make the point that AGW is a secular religion, and there is support for that at the green-agenda website,
http://www.green-agenda.com
which features extensive quotes from leading AGW figures, and essays by the author.
I would like to add a general psychological comment. Scientists and engineers are trained (or brainwashed) to think of a problem as ‘something to solve’, and are puzzled when rational analysis and solutions are ignored by political and cultural leaders. In the mind of a high cultural or political leader, problems are ‘something to exploit’, and all the well informed technical commentary on this website is naive. If one of the higher figures quoted on the green-agenda site actually bothers to read this site, they would be mildly amused by the earnest comments from former straight-A students.
An example: the Petition Project has collected more than 30K signatures against the Kyoto Treaty, and the public impact is … zilch. Another simple example: the basic numbers, such as the 0.04% level of carbon dioxide and the one-hundredth-of-one-percent expected increase, etc, have not penetrated to the public level.
If the rational side expects to make any impact, they will have to learn a lot more about psychology, politics, economics, and so on. They could at least try to recapture some of the scientific organizations that are still in the AGW camp. I might add that ‘capture’ is a standard term in social science; the Wikipedia has an article on Regulatory Capture, for example. The AGW leaders are working on a world capture, in effect.

The thing that makes the AGW argument withstand criticism is the fact that the theory is combined with a plausible mechanism complete with mathematical equations, computers, elaborate models, funding, and media coverage. With media coverage added to the mix, any attempt to falsify AGW, no matter how well done, will have little power.
This is what I don’t understand. There is an equation that governs how the increase in CO2 effects the absorption lines and from what I have seen, the sensitivity to CO2 is an order of magnitude less than what is claimed from Hansen’s empirical relation. I would really like to know why this has not been presented or at least show me where I am wrong.

Why the 3rd International Climate Change Conference? To release the 2009 report of the Nongovernmental International Panel on Climate Change – NIPCC Report
See: Climate Change Reconsidered
News: The Climate-Change Report the UN Failed to WriteNews Releases > June 2009

WASHINGTON, D.C. — The 2009 report of the Nongovernmental International Panel on Climate Change is the report on global warming the United Nations’ climate panel should have written–but didn’t.
The 880-page report, released today at an international meeting in Washington DC of scientists and policy experts, rigorously critiques the 2007 Fourth Assessment Report of the UN’s Intergovernmental Panel on Climate Change (IPCC), which concluded that harmful global warming “very likely” has been due to human activity in the release of greenhouse gases.
The science behind that conclusion is soundly refuted in Climate Change Reconsidered, coauthored by Dr. S. Fred Singer and Dr. Craig Idso. In nine chapters citing thousands of peer-reviewed research papers and books that were ignored by the UN, plus new scientific research that became available after the UN report’s deadline, the Nongovernmental International Panel on Climate Change (NIPCC) marks a new chapter in the debate over global warming. . . .Joseph Bast, editor of Climate Change Reconsidered and president of The Heartland Institute, the book’s publisher, said, “Until now, the huge body of peer-reviewed science that contradicts the overheated claims of global warming alarmists hadn’t been brought together into a single authoritative document that challenges, point by point, the latest reports of the UN panel. Climate Change Reconsidered does this, and the effect is devastating.
“None of the UN document’s principal claims is left standing. No objective reader can walk away from the NIPCC report without realizing how weak the case is for alarm over global warming. Global warming simply is not the crisis so many politicians and activists claim it is. It never was,” Bast said.
The Heartland Institute released Climate Change Reconsidered at the Third International Conference on Climate Change, June 2 at the Washington Court Hotel in Washington, DC.

George E. Smith (10:09:46)
The entire notion of feedback in the climate system stems from a fundamental miscomprehension in “climate science” of what that term really means and what it analytically implies. They think that any nonlinear response is “feedback,” and constantly seek power-amplifying mechanisms to explain their misconceptualizations. They don’t even understand that power can’t be reused and that independently-powered operational amplifiers are used in control systems to maintain bona fide feedback. Say “impedance” to them, and you’ll get a blank stare.
You’re right. Thermalization of insolation is what drives the climate system. Atmospheric backscattering of LW radiation is a power-redistribution, rather than a power-generating mechanism, and that’s all that’s involved in the “greenhouse effect.”
Got more serious matters to attend to. Keep them honest, George.

Pamela Gray (07:16:02) :
“Falsifying it without coming up with anything else is like trying to destroy a tank with a hammer. That little phrase “What else could it be?” becomes a clanging bell extolling a default AGW win if we cannot come up with an equally plausible elaborate mechanism and overriding theory.”
Jeff Alberts (07:46:04) :
“I don’t think there is any “it”, but I do understand your point. So far no one has shown that we’re seeing anything out of the ordinary. But the AGW clique says we need to disprove them and come up with a valid “explanation”. I don’t see anything that needs explaining.”
While I understand the sentiment here I disagree very strongly. Just because we don’t have a much better explanation does not mean a wrong one should be accepted until we get a good one. Expecially not when you consider the incredible cost in terms of the economy and human welfare.
It is the theory that has the burden of proof, that is the way science works. It is not required that the experiment providing falsification also produce a new theory and in fact it would be unusual if it did.
As it stands now, natural variation is a more plausible explanation than catastrophic AGW, with assuming the value of feedback being much smaller than IPCC assumptions also being a better fit to the data than either.
