Former alarmist scientist admits global warming is a “fiction”

Leave a comment

David Evans consulted full-time for the Australian Greenhouse Office (now the Department of Climate Change) from 1999 to 2005, and part-time 2008 to 2010, modelling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. And then he stopped working for them. Now that he is no longer obligated to toe the party line, he explains what global warming really is about. (H/T Neil Simpson)

Excerpt:

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. Watching this issue unfold has been amusing but, lately, worrying. This issue is tearing society apart, making fools out of our politicians.

Let’s set a few things straight.

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.

The evidence that was ignored by the global warming alarmists:

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.

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.

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.

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.

Read the whole thing.

The Blog Prof also linked this useful video in which a Physics professor from the University of California at Berkeley explains the Climategate scandal.

These revelations should mark the end of global warming alarmism, but they won’t, because global warming is such a useful fiction for so many people. As the article noted, it’s a source of endless research grants and prestigious travel budgets for researchers in academia who must apply for government money before they can prove what the governments wants them t0 prove – namely, that government needs to control individuals and corporations. It provides those who reject traditional morality with a way of feeling better about themselves by being “moral” about recycling, turning of their lights and not having any children. It gives people a feeling of pride, because they are better than those greedy oil companies that pay a 40% tax rate, much higher than the 0% paid by companies that are favored by the Democrat Party, like GE. It also provides a useful fiction for the socialists to mislead the public into voting for them to “solve” the “crisis” with bigger government, higher taxes and less individual liberty.

What are the economic effects of the green environmentalist agenda?

From Investors Business Daily.

Excerpt:

Some day, environmental radicals will be held accountable for crimes against the ecosystem — the human ecosystem.

Back in 2007, they convinced federal Judge Oliver Wanger to rule that the Endangered Species Act gave the federal government the right to cut water to thousands of farmers in California’s Central Valley to protect a 3-inch baitfish called the delta smelt.

That ruling turned many of the Valley’s prized vineyards and almond groves into wastelands. Jobs were lost, family farms were shut, fields went fallow and food prices rose.

But there’s been just one problem with this overreaching of the law: Cutting off water didn’t save the smelt.

A draft of a new study from the Delta Stewardship Council shows the water cutoffs had no effect on the smelt. The smelt remains endangered even as farmers have been punished with a policy that cut off as much as 90% of their water.

“Environmentalists claimed the sky was falling in Delta, and the only way to save smelt was to flush more fresh water to the ocean,” said Andrew House, spokesman for Rep. Devin Nunes, R-Calif. “So they embarked upon a narrow path of diverting water from (San Joaquin Valley) farmers by using science to confirm their predetermined assessment of what was going on.”

But it didn’t work. Similar evidence is now coming out from the Pacific Northwest stating that shutting down the logging industry never did save the spotted owl.

In both cases, the science was highly speculative and new predatory species seem to be more likely causes. But that never stopped cocky environmentalists from saying they had all the answers — and all the power.

“Our farmers went through two years of supply cuts to have . .. better information and science, ” said Steve Wade, executive director of the California Farm Water Coalition, commenting on the report.

Wade noted that the water shut-off has been particularly hard on family farms, many of which have gone under as a result of the policies. He said their farms have been bought out by big agribusinesses, ironic given environmentalists’ hatred of that.

Unemployment reached 40% in some areas as a result of the cutoff, and even cities like Fresno (with an unemployment rate above 16%) ended up losing 25% of their water, too.

Food lines appeared in the world’s most fertile agricultural valley, with farmworkers accepting bags of carrots grown in China, a sorry emblem of man-made famine.

House notes that not only did the water shut-off wreak havoc on Central Valley farms, its smelt-saving basis — which Judge Wanger later called “sloppy science” — managed to endanger the smelt even more by not addressing the real reason for the creature’s demise.

“They wasted so much time focusing on a phantom problem, they haven’t examined what the real problems are. Now you have the Delta Stewardship Council saying” the species may not be saved, House said.

This was never about science anyway. “It was … about re-engineering the development of California, particularly the San Joaquin Valley,” said House. “They don’t think the west side should be farmed at all, they want it removed from production, gone to a natural state, re-engineered as a socialist Utopia.”

Real people’s lives were ruined by this green alarmism. And it’s happening everywhere. People losing their jobs, paying more for electricity, food riots and even people dying from malaria in the third world because of DDT bans.

Several states considering bills to promote academic freedom

Leave a comment

From Evolution News.

Excerpt:

Across the country legislation is moving forward that will protect teachers and students who want the freedom to discuss both the strengths and weaknesses of modern evolutionary theory.

[…]To help combat the dogmatism that presently pervades evolution-education, Discovery Institute supports legislation that protects academic freedom for teachers who would dare to challenge Darwin in the classroom. There are presently academic freedom bills in Oklahoma, Tennessee, New Mexico, Kentucky, and Missouri.

As is expected, misinformation is already being spread about the bills. Yesterday I was informed that Oklahoma evolutionists are continuing to spread the myth that Louisiana’s Academic Freedom Law was declared unconstitutional. The truth is that the law hasn’t even been challenged in court. As I discuss here, ACLU Executive Director Marjorie Esman reportedly acknowledged that “if the Act is utilized as written, it should be fine; though she is not sure it will be handled that way.”

ClimateProgress is putting out the false claim that the legislation “forces teachers to question evolution.” That’s false. An academic freedom bill does not require teachers to teach anything differently. Topics like evolution will still be taught as a matter of required state law. All students will still need to learn and will be tested upon all aspects of state science standards. The bill still mandates that teachers follow the curriculum and teach the pro-evolution evidence. But it also gives teachers academic freedom to teach about credible scientific viewpoints that challenge the neo-Darwinian “consensus”–if they choose to do so.

And of course, we’re also hearing the standard false claim that the bills allow the teaching of creationism or religion. Despite the talking points of critics, academic freedom bills would not authorize or protect the teaching of creationism or any other religious viewpoint. According to a number of federal court rulings, creationism is a religious viewpoint that is illegal to advocate in public schools. Consistent with these rulings, most academic freedom bills contain language that expressly excludes the teaching of religion and only protects the teaching of scientific information.

I’m sure that if I looked at those bills that they are being sponsored by Republicans. Academic freedom – the freedom to question authority about evidence – is very important to conservatives.
