Neither Taylor nor Meyer (nor most other climate change skeptics, some of whom call themselves "global-warming optimists") deny that modern human development in the form of additional greenhouse gases has played a role in warming the planet.
But most of them agree with Meyer when he says, "To this day, there's still no empirical proof of how much warming is coming from CO2. There's a lot going on, and it's almost impossible to pick effects out."
Warming oceans tell a different tale
That flies in the face of what most scientists say. "For me, the most compelling single data set that undermines that suggestion is the increase in the heat content of the oceans," says Daniel Lashof, science director for the climate center at the Natural Resources Defense Council in Washington, an environmental lobbying group.
Another environmental group, the Union of Concerned Scientists, notes that higher temperatures have been found 1,500 feet deep in the ocean. It calls ocean warming the No. 1 "human fingerprint … well outside the bounds of natural climate variation."
"There's just no argument about it," Dr. Lashof says. Heat "is going down hundreds of feet … an accumulation of heat that there's just no other explanation for other than that the earth has been driven out of energy balance with the sun by this accumulation of heat-trapping gases in the atmosphere."

That said, it is striking how their arguments are so similar to the anti-evolutionists, that "we just don't know FOR CERTAIN, so let's do nothing." And then ignore the best evidence out there to focus on the most sketchy areas to make their points.
