This last week we saw the power of branding in the political arena. By rebranding anthorpogenic global warming as “climate change,” alarmists are able to say things like this (this is White House spokesman Robert Gibbs commenting on recent very cold weather)
Gibbs: “I think that one only has to step outside here or visit where I used to work in Chicago to understand that climate change, and the record temperature that climate change is likely causing, is with us….I would say that eve in places that are used to getting very cold weather, record cold…our weather patterns have been affected by change in our climate”
Wow, I guess its all about the science. Except for the following problem: no living human being has suggested any credible mechanism by which CO2 can cause climate change without the intermediate step of warming. CO2 causes warming, which in turn might or might not cause more, say, severe storms. But there is no evidence of CO2 causing more temperature volatility (particularly extremes to the cold side) and even those who have suggested that global warming might lead to more volatility would be forced to admit, if they are being honest, that this is more volatility around a higher mean, such that there still should not be a lot more record lows.
