An Inconvenient Truth for Gore

Scientists are skeptical on the claims in Al Gore's movie An Inconvenient Truth:
"Scientists have an independent obligation to respect and present the truth as they see it," Al Gore sensibly asserts in his film "An Inconvenient Truth", showing at Cumberland 4 Cinemas in Toronto since Jun 2. With that outlook in mind, what do world climate experts actually think about the science of his movie?

Professor Bob Carter of the Marine Geophysical Laboratory at James Cook University, in Australia gives what, for many Canadians, is a surprising assessment: "Gore's circumstantial arguments are so weak that they are pathetic. It is simply incredible that they, and his film, are commanding public attention."

But surely Carter is merely part of what most people regard as a tiny cadre of "climate change skeptics" who disagree with the "vast majority of scientists" Gore cites?

No; Carter is one of hundreds of highly qualified non-governmental, non-industry, non-lobby group climate experts who contest the hypothesis that human emissions of carbon dioxide (CO2) are causing significant global climate change. "Climate experts" is the operative term here. Why? Because what Gore's "majority of scientists" think is immaterial when only a very small fraction of them actually work in the climate field.

Even among that fraction, many focus their studies on the impacts of climate change; biologists, for example, who study everything from insects to polar bears to poison ivy. "While many are highly skilled researchers, they generally do not have special knowledge about the causes of global climate change," explains former University of Winnipeg climatology professor Dr. Tim Ball. "They usually can tell us only about the effects of changes in the local environment where they conduct their studies."

This is highly valuable knowledge, but doesn't make them climate change cause experts, only climate impact experts.
