It would be nice if the folks writing these sorts of articles would stop referring to these people as "skeptics". They are not skeptical, a skeptic can be convinced by evidence. These people are anti-science. It's an accurate title.
The test to determine who is anti-science is simple; just ask them this question: In your own personal opinion, what specific evidence would have to be presented to convince you that the scientific theory of AGW is correct?
A skeptic can answer it with "I don't know", or they could state something specific they feel would be significant. Only someone who is anti-science cannot answer that question.
The anti-science types either don't know what evidence is already available and don't want to make themselves look like even bigger idiots if it turns out what they want is already at hand, or else they don't know enough about climate science to be able to name something that might have a plausible link to global climate change.
Either way the science will make them look ridiculous.
Please call them anti-science. They want to be called anti- everything else; anti-abortion, anti-tax, anti-big government, anti-gay marriage. Use the naming convention they have chosen, they are anti-science. ...
