An illustration of why it’s not debatable

The site is named and you’d think that it’d present reasonable material. Steve Chapman illustrates otherwise in Ted Cruz’s Climate Change Festival of Fraud
Response to global warming evidence mischaracterizes the truth
. Sounds good but only if you don’t consider what is being offered.

Consider the start: “You have to feel sorry for Ted Cruz.” This is called ad hominem and illustrates that the issue at hand is attacking the person and not climate change.

Then there is “The topic was global warming. Every major scientific body has confirmed its existence, but as “the son of two mathematicians and computer programmers and scientists,” he feels particularly qualified to debunk it.” This is an appeal to authority citing appeal to authority – double whammy. Do remember that Mann’s hockey stick debunking was done by a statistician.

Then considered this discovery of the victim’s flaws: “The second is that the satellite data don’t refute global warming. NASA says that based on surface temperatures.” There seems to be some conflict between satellite and surface measures. Choosing one or the other to suit one’s desires doesn’t instill confidence that truth is being sought. Keep in mind that the surface data record is subject to continuous “adjustments” while the satellite data is not. The most recent brouhaha deals with decisions about ship cooling water inlet temperatures being considered more reliable than buoy data. 

This same sort of confusion is evident in “The same data indicate that of the 14 hottest years ever, 13 occurred in this century. When Cruz says there has been “no significant warming” since 1997, he’s engaging in brazen deception.” The problem here is that rate of change is being confused with actual position. There is also a problem in asserting extremes without considering the facts that the measures are within margins of error and the reference period chosen is usually just recent history and quite limited.

Then there’s the money corruption angle: “Which scenario is more plausible, thousands of scientists pretending to believe in global warming to get government grants or Cruz denying it to get campaign donations?” Perhaps Chapman forgets Climategate from a few years back? In one case there is blatant evidence of corruption. In the other, only allegation. Sliming with a perceived taint of money is a phenomena that deserves proper attention as an escape from “reason.” 

The debate deserves better than this.
