Film Exposes Gore’s Deceptions

Then, in March 2007, the UK’s Channel 4 broadcast a biting documentary, The Great Global Warming Swindle. It debunked most of the major arguments of Al Gore’s Oscar-winning video, An Inconvenient Truth. For example, the Antarctic ice core data dramatized in Gore’s show actually reveal that increases in CO2 have generally followed increases in temperature. The lag is typically on the order of 800 years.

The Swindle documentary roused furor and scorn among carbon-as-cause believers, who attacked Channel 4 as offering a “great propaganda gift” to “climate-change deniers.” But the credibility and rationale of scientific sources on the documentary endured the attacks. No factual challenges were forthcoming against the scientists’ arguments.

The controversy over this TV show, the first journalistic challenge against CO2 as primary world thermostat, may have encouraged others in the scientific community to point out that despite roughly $50 billion for climate-change research over several decades, the case against carbon dioxide faces more uncertainty as the evidence grows, not less.

One such challenge comes from Dr. Bob Carter, Research Professor at James Cook University and paleoclimate analyst with more than 30 years’ experience, including 95 research papers.

In an Accuracy in Media guest column in April 2007, Carter emphasized: “The evidence for dangerous global warming forced by human carbon dioxide emissions is extremely weak. That the satellite temperature record shows no substantial warming since 1978, and that even the ground-based thermometer statistic records no warming since 1998, indicates that a key line of circumstantial evidence for human-caused change-the parallel rise in the late 20th century of both atmospheric carbon dioxide and surface temperatures-is now negated.”

(and)

Temperature and CO2 cycles deciphered from Antarctic ice cores reveal that new temperature uptrends in CO2 levels have typically followed new temperature uptrends by 600 to 1,200 years. If that has been the case historically, it’s hard to claim that CO2 caused those temperature uptrends to begin.

One of the most dramatic screens in Al Gore’s documentary, An Inconvenient Truth, shows a chart where temperature and CO2 levels wriggle through thousands of years in apparent synch with each other.

Flashed on a wide screen for moments, the long series of cycles appear tightly coupled. Audiences gasp. Gore declares that to deny this linkage is the “silliest thing I’ve ever heard.”

But the statistical correlations of these measurements derived from ice cores are highest when temperature data is mathematically lagged about 800 years after CO2 data. This indicates that temperatures rise first, and carbon dioxide in the atmosphere follows.

This relationship makes sense. Warming oceans release CO2. It takes decades for the world’s oceans to warm after a long cooling cycle. University of Colorado research indicates that as Earth started to warm after the most recent Ice Age, the oceans have released some 600 billion tons of carbon into the atmosphere as CO2.

Also, why do ancient climate records extracted from ice cores show global cooling cycles in the wake of CO2 increases? Some scientists argue that the world’s vegetation increased, locking CO2 into “carbon sinks.” That simply helps make my agriculturist case that a world richer in CO2 could be a greener world.

Even in recent years, climate variations have occurred over decades, despite a steady rise in atmospheric carbon dioxide.

Radiosonde data revealed wide annual temperature swings in the troposphere, including drops of 0.8 degree below average after 1930. In the mid-1970s, I was writing newsletters for farmers when this “global cooling” fanned media stories of coming climate disaster. Our farm news and advisory organization, Professional Farmers of America, held “World Food Crisis” conferences to study how global agriculture might cope with a potential worldwide cooling.

Today, global-warming activists shrug off the fact that during the 1930-80 cooling in North America, CO2 was probably rising at 1 to 2 parts per million annually – close to the annual rate it is rising today.
