"In 2005, a Canadian Greenpeace representative explained “global warming can mean colder, it can mean drier, it can mean wetter.” In other words, all weather variations are evidence for global warming. I can't make this stuff up"
Thats the key. The "faithful, who want to believe this myth of their own making for their own selfish political purposes will see what they wish to see. The Liberal media can be counted on to ignore scientific evidence to the contrary and endlessly promote the big lie. After all, those are lies in service of the bigger Liberal truth, so it's OK.
For Libs, any lie or misdeed is acceptable in the pursuit of their coming Liberal nirvanah. Gosh, if only THEY were in power then they could force us all to live as they wish us to, and the world would be instant Liberal perfection. There would no longer be global warming, no poverty, no ice storms and never a discouraging word, because they would stuff those attempting to speak their minds contrary to Lib orthodoxy into mental institutions like Putin is doing in Russia now. Of course, it would all be for our own good.
Global Warming Theory is very robust with respect to data, all observations confirm it with probability 1.
