This snippet comes from a WSJ column very critical of Gore and his new movie. The interesting part is how it frames the issue and the difficulty in reaching any useful scientific certainty about causes and effects:

"That man-made carbon dioxide has a net planetary warming effect is an important hypothesis, one that science can make stronger or weaker, but can't prove. It may be true, but a layperson only has to look into the antecedents of today's "consensus" to realize it wouldn't be too surprising if tomorrow's consensus were that CO2 is cooling, or neutral, or warming here and cooling there.

And evidence of warming is not evidence of carbon-driven warming. These are different things, at least until scientists can be reasonably certain they've eliminated other factors and interrelationships that contribute to climate variability. But scientists are not close to understanding or even knowing all the factors that play into "climate change," a process that might as well be called "climate," since climate is always changing.

Finally, warming and what might cause warming are subjects entirely separable from the urge to gather up all the most dire and extreme speculation about what a warming earth would be like for humans and present it as scientific "truth."
