I have no specific opinion about human caused climate change.
I think the science is too complicated (and politically charged) to come to any kind of reliable conclusions and I see little point in artbitrarily choosing to believe one way or the other. Think about the number of factors involved between atmospheric composition, solar radiance fluctuation, surface reflectivity, cloud formation catalysts, and so on. It is a difficult question.
The WSJ thinks that we are seeing an international move away from belief that we're responsible.
I just hope gov'ts won't throw baby out with the bathwater. Other types of pollution and environmental degradation are undeniably real: deforestation, fish stock depletion, China's dirty coal addiction (the US and Europe use coal too, but we scrub our smokestacks to take the carcinogens out instead of fogging our cities with it), Europe's diesel particulate issues, soil erosion, worldwide groundwater depletion. These are all obvious and comparatively easily solved problems that have been pushed aside by the carbon debate.
And, of course, there is always the other side of the CO2 problem. The nasty, scary, possibly irresolvable part: that we are depleting the world's cheap energy reserves.
