“There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.”—from the Oregon Petition, signed by over 31,000 scientists.

United by that conviction, over 800 scientists, economists, and policy makers arrived in New York City last Sunday to attend the Heartland Institute’s 2nd Annual International Conference on Climate Change. They came to talk a wide range of subjects, from climatology to energy policy, from computer climate models to cap-and-trade, from greenhouse gas (GHG) effects to solar irradiation. But most of all they came to help spread the word that the answer to the question posed by this year’s theme—Global warming: Was it ever really a crisis?—is a resounding NO.

Sunday’s keynote speakers wasted no time making that point. Czech Republic President Vaclav Klaus scolded those whose alarmist opinions are driven by profits from writing and speaking fees, carbon trading and investments in non-carbon fuel products. And policy makers who blindly accept hyped Intergovernmental Panel on Climate Change (IPCC) publications as the final word in climate science. In truth, says Klaus, there is no fixed relationship between CO2 and temperatures, as clearly illustrated by the wavering heat trends of the 20th century, despite the steady rise in CO2.

Next, M.I.T’s Richard Lindzen explained that many scientists tow the anthropogenic global warming (AGW) line to “make their lives easier,” as underfunded scientists can write a single paper endorsing AGW and suddenly be inundated with offers. Even ambiguous or meaningless statements that can be easily spun are financially beneficial to scientists, so why complain about the spin? Ever wonder why you never stop hearing about studies finding GW responsible for everything from kidney stones to cannibalism? Explains Lindzen:  It’s become standard that whatever you’re studying, include global warming’s effects in your proposal and you’ll get your funding.

Lindzen then dismissed climate models that alarmists depend on as they themselves depend entirely on warming positive feedback but, unlike nature, ignore the cooling effects of negative feedback. And rejected the warming alarmists alarm us about as so miniscule that there’s no need for any external forcing to achieve or explain it. In reality, said the world renowned atmospheric physicist, doubling or even tripling CO2 would have only marginal impacts on temperatures.  Both speakers masterfully set the stage for the days and sessions to come. What follows is just a sampling of the brilliance I encountered.

Roy Spencer echoed Lindzen’s position that negative feedbacks ultimately bring equilibrium to the energy balance, making sustained global warming a non-issue. David Douglass assured us that ocean and atmospheric heat will always work toward such balance as per conservation of energy laws. S. Fred Singer commented that a 2005 paper by Hansen et al claiming that Earth’s energy imbalance is proof of AGW was absurd. Geologist and former astronaut Jack Schmidt inverted the IPCC position that burning fossil fuels increases atmospheric CO2, which in turn warms the planet. Slowly increasing temperatures from 1660 AD or so, said he, would increase CO2 and methane from land, land confined water, the biosphere and, mostly, the oceans. The vapor pressure of CO2 is temperature sensitive. So as a matter of established physics of gases, we’d expect atmospheric CO2 to increase as temperature increases. Therefore, he concludes, saying that CO2 causes heating is like saying “accidents cause speeding.”

Singer moderated a panel discussion thoroughly debunking a recent paper claiming that CO2 put into the atmosphere lasts thousands of years. Participant Douglass questioned the premise as “it has nothing to do with global warming as CO2 continues to rise but GW stopped after 1991.” But as Singer pointed out, alarmists will claim it proves that peak values reached in the next few years will determine climate for the next millennium. And Christopher Essex nailed it: Their 1000 year forecast is remarkable - even groundhogs only predict 6 months ahead.

Astrophysicist Willie Soon proclaimed the sun-induced climate change theory alive and well. He believes that, while IPCC AR4 fraudulently disregarded Milankovitch’s theory of orbital influences on climate, the comings and goings of the ice ages may be controlled by changes in solar insolation at climatically sensitive latitudes. He displayed adjacent line graphs overlaying 20th Century arctic temperature anomalies with solar irradiance levels on one and atmospheric CO2 levels on the other. Whereas the former lined up almost perfectly, the latter wasn’t even close.  Jack Schmidt pointed out that the 1400 -1900 cold period known as the Little Ice Age corresponds to a cycling sequence of 3 deep minima of sunspot activity and was at its coldest during the last of these minima, the 70 year period of exceptionally few spots we now know as the Maunder Minimum. Dennis Avery reinforced his 1,500 year climate cycle argument and its implications for the current warming period. He told us that solar variations are linked to decade-lagging sea temperatures. What’s more, diminished sunspot activity since 2000 and Pacific Sea Surface cooling since 2008 predict a 20-30 year global cooling due to short term Pacific Decadal Oscillation (PDO). Don Easterbrook neatly tied variances in the PDO and another natural climate variability, the Atlantic Multidecadal Oscillation (AMO), to that of solar activity and, ultimately, temperatures. The geologist pointed out that while the IPCC predicted 1F warming by 2011, there’s been none since 1998, and that the 1F drop in 2008 was the largest global temperature change ever recorded. He too believes that the current PDO cool phase assures global cooling for as long as the next three decades.

Roy Spencer blamed the PDO for 75% of twentieth century warming. He provided a line graph plotting temperatures against the PDO and the correlation was quite remarkable. Weaker PDOs yielded warmer temperatures and the onset of stronger circulations cooled things down. As one might suspect—Spencer’s graph depicted a decided cooling trend beginning in 2003. ICECAP’s Joe D’Aleo also made an extremely compelling argument against the greenhouse effect and for the natural climate drivers of oceans, the sun, and yet another—volcanoes. On D’Aleo’s graphs, PDO/AMO aligned well with USHCN temperatures over last century, as did stratospheric aerosol levels from volcanic eruptions, and total solar irradiance. He remarked that “all three show a cycle where the last few years look a lot like the 1960’s,” which immediately caught my attention. You see, just hours prior, I had been discussing NY weather with a British representative and had commented that this winter reminded me of those I experienced as a child in the 60’s.

California Congressman Tom McClintock offered examples of just how global warming is damaging his state --- all in the form of radical construction blocking, agriculture crippling, resource wasting legislation the warm-mongers have gotten through to fight it. Here’s a beauty—a homeowner can be fined $1000/day for refusal to cut down his trees if they block a neighbor’s solar panels, but also faces fines if he cuts them down or clears brush for fire preventive purposes. And Gov. Schwarzenegger - who just proposed the largest tax increase in history to make up for funds lost by his failed green policies—wants Cal-E-Fornia to be “an example to the country.” Bennie Peiser, founder and editor of the fabulous CCNet, explained the political backlash European greenies are experiencing. And it’s pretty bad—Labor and Green parties are seeing the amalgamation of the recession and failed Kyoto-inspired energy policies driving their core voters away. Lawrence Solomon offered more examples of overseas carbon regulation disasters, declaring Kyoto the greatest single destroyer of the environment, especially in the third world. Dave Kreutzer warned that analytical models predict estimated aggregate losses to Gross Domestic Product (GDP) of $4.8 trillion and job losses in the manufacturing sector of nearly 3 million by 2029 if CAT were imposed under S. 2191. That’s over and above the million manufacturing job losses economists predict will occur even if we do nothing.

And the losses will extend beyond the monetary. Professor Arthur Robinson, author of the afore-quoted Oregon petition, revealed the true reasons we import 30% of our energy, even though “one Palo Verde Nuclear Installation in each state results in $200 billion net export of energy.” Robinson says there are those who would prefer that 30% grow much larger, encouraging higher energy prices and ultimately - rationing. And quickly advised—once we become victims of rationing in the west we lose our all of our freedoms, but energy deprivation in third world countries will lead to the loss of tens of millions of lives.

And Monckton took on another deadly green scheme as only his Lordship can: “Their biofuel scam, a nasty by-product of their shoddy, senseless, failed, falsified, fraudulent ‘global warming’ bugaboo, has turned millions of acres of agricultural land from growing food for humans to growing fuel for automobiles. If we let them, they will carelessly kill tens of millions more by pursuing Osamabamarama’s stated ambition of shutting down nine-tenths of the economies of the West and flinging us back to the Stone Age without even the right to light fires in our caves.”

Retired senior NASA atmospheric scientist John Theon expressed his regret that former employee, James Hansen, “didn’t receive the attention from me that he should have.” What followed was a heartfelt denunciation that included the fact that Hansen’s 1988 announcement of “unprecedented global warming” came as a surprise and embarrassment to Theon, as it was not NASA’s position. He then cried foul over Hansen’s endorsement of John Kerry for president in 2004, particularly after receiving the Heinz Environment Award, a $250,000 prize honoring the late-husband of Kerry’s wife in 2001. He pointed out that a civil servant endorsing a political cause violated the Hatch Act, and that alone should be grounds for dismissal, which he has publically called for. Says Theon: “I think the man is sincere, but he is suffering from a bad case of megalomania.”

There were a number of problems with data collection methods discussed. Tom Segalstad gave us a lesson in the dubious integrity of ice-core samples. WUWT’s Anthony Watts favored us once again with stories and photographs of misplaced Maximum-Minimum Temperature Systems (MMTS). He and his cohorts have photographed and analyzed 75% of the 1200 plus national weather stations, and the results range from bad to hysterically bad. One slide showed a station in Detroit Lakes, Minnesota where the thermometer was placed within feet of not one, but two air conditioning outlets. The fact this town reported temperature well above those of its neighbors didn’t seem to raise any red-flags with the good folks ate NOAA. So it’s not particularly shocking that only 11% of stations surveyed met the required Class I or Class II requirement of likely measurement error under 1C.  Joe D’Aleo believes that surface data suffer from serious issues biasing them to the warm side, this due to station dropout, missing monthly data, and inadequate or nonexistent urban heat island effect (UHI) adjustment. Half of the warming since 1880 may be attributed to these measurement contaminations. In fact, Climate Audit’s Steve McIntyre said we don’t actually know that the 1998 was the warmest year of the millennium as minor variations in data version yield different results.

There was also much talk about response and adaptation: Dennis Avery reminded us that history shows that warm times have been good times. During the Medieval Warm Period, world population doubled, crops flourished, there was less disease and no bubonic plague. Most of Europe’s castles and cathedrals as well as India’s most famous temples were built during that period. And that as polar bears date back 130,000 years, they’ve managed to adapt through many warming periods more severe than the current one.

During Tuesday’s standing-O-rousing conference-closing speech, in which he marvelously referred to alarmists as “bed-wetting moaning Minnies of the Apocalyptic Traffic-Light Tendency—those Greens too yellow to admit they’re really Reds,” Lord Monckton added: “Every opinion poll--even those conducted by the bed-wetters themselves - shows that global public opinion is cooling as fast as the global climate. In one recent survey, ‘global warming’ came at the very bottom of a list of political and environmental concerns, immediately behind the need to clean up dog-poop on the streets. Why? Because dog-poop is a real environmental problem and ‘Global warming’ is not. The correct policy response to the non-problem of climate change is to have the courage to do nothing.” And then emphasized unequivocally: “There is no climate crisis. There was no climate crisis. There will be no climate crisis.” Read much more of this excellent, thorough review of the conference here. See videos of the keynotes (and soon of all the talks) and powerpoints of the talks here.
