I was very impressed by the quality of his ideas and presentation, debunking the climate science that is being taken as gospel by the administration, and the resulting need to "do something!" to fix it. His arguments are carefully structured, accessible to the scientific layman, and he weaves in historically analogous situations to support his points. I can't recommend it highly enough (though I wish he would have stopped before writing the last two paragraphs.) As an anecdote unequivocally proving the potency of the speech--you only need one data point for proof, right?--I sent it to a friend, who sent it to his girlfriend, who sent it to her father, a retired oceanographer, and he is now afire with new ideas questioning all sorts of old notions.
Here are a few choice quotes, but they don't do the speech justice. I recommend downloading the PDF from this site and printing it out. You'll want a pen handy to underline key points. It's that good.
On Gore and causality:
Al Gore likes to display graphs of temperature and CO2 concentrations over the past million years or so, showing that when CO2 rises, the temperature also rises. Doesn’t this prove that the temperature is driven by CO2? Absolutely not! If you look carefully at these records, you find that first the temperature goes up, and then the CO2 concentration of the atmosphere goes up.On the corruption of language, and thus of concepts:
There is a delay between a temperature increase and a CO2 increase of about 800 years. This casts serious doubt on CO2 as a climate driver because of the fundamental concept of causality. A cause must precede its effect. For example, I hear my furnace go on in the morning about six o’clock, and by about 7 o’clock, I notice that my house is now so warm that I have too many covers on my bed. It is time to get up. It would never occur to me to assume that the furnace started burning gas at 6 o’clock because the house got warm at 7 o’clock.
I keep hearing about the “pollutant CO2,” or about “poisoning the atmosphere” with CO2, or about minimizing our “carbon footprint.” This brings to mind another Orwellian pronouncement that is worth pondering: “But if thought corrupts language, language can also corrupt thought.” CO2 is not a pollutant and it is not a poison and we should not corrupt the English language by depriving “pollutant” and “poison” of their original meaning.On the folly of trying to claim there is some "ideal" concentration of CO2 that we must go back to:
I remember being forced to read Voltaire’s novel, Candide, when I was young. You recall that Dr. Pangloss repeatedly assured young Candide that he was living in “the best of all possible worlds,” presumably also with the best of all CO2 concentrations. That we are (or were) living at the best of all CO2 concentrations seems to be a tacit assumption of the IPCC executive summaries for policy makers.But one of my favorite parts comes early in the speech where he talks of the futility of past efforts to to change the climate by wishing.
The climate has changed many times in the past with no help by mankind. Recall that the Romans grew grapes in Britain around the year 100, and Viking settlers prospered on small farms in Greenland for several centuries during the Medieval Climate Optimum around 1100. People have had an urge to control the climate throughout history so I suppose it is no surprise that we are at it again today. For example, in June of 1644, the Bishop of Geneva led a flock of believers to the face of a glacier that was advancing “by over a musket shot” every day. The glacier would soon destroy a village. The Bishop and his flock prayed over the glacier, and it is said to have stopped. The poor Vikings had long since abandoned Greenland where the advancing glaciers and cooling climate proved much less susceptible to prayer. Sometimes the obsession for control of the climate got a bit out of hand, as in the Aztec state, where the local scientific/religious establishment of the year 1500 had long since announced that the debate was over and that at least 20,000 human sacrifices a year were needed to keep the sun moving, the rain falling, and to stop climate change. [bold added]Although the Bishop of Geneva's praying obviously worked -- wait... what was that about causality? -- the thought of someone praying in front of a glacier to make it stop made me chuckle. Then today, a friend sent me a link to some National Geographic photos of Indonesian cultures living near volcanoes. He was fascinated by the first photo, which is truly breathtaking. But I was amazed at seeing these human beings, living on earth, today, praying to volcano gods. The last photo was perhaps the most striking, taken along with its caption:
This man is praying to stop mud, just like the Bishop prayed to stop the glacier, and the Aztecs sacrificed thousands to their gods. Now the environmentalists and their friends in power are looking to march the economy, and therefore all of us, up to the top of the temple to sacrifice us to their climate god via Cap and Trade. Rather than appealing directly to faith, these last claim to fly the flag of science, all the while persecuting those who disagree with their hysterical claims as if this were an auto da fe.
If you're at all interested in this issue and would like some good points to bring up when you hear the typical "Denier!" assertions, or if you know someone on the fence who might be just active minded enough to listen to reason, you'll want to read this testimony and pass it on.
