What we have here is a case of dogged contrarians who present results in ways intended to deceive the public into believing that the changes have greater significance than reality.”
This deceit has a clear purpose: to confuse the public about the status of knowledge of global climate change, thus delaying effective action to mitigate climate change.”
Attached is a very well written response by NASA's Jim Hansen to the contrarian glee over the minor adjustments made to their US temperature data.
More choice quotes:
“How big an error did this flaw cause? That is shown by the before and after results in Figure 1. The effect on the global temperature record is invisible. The effect on U.S. average temperature is about 0.15°C beginning in 2000. Does this change have any affect whatsoever on the global warming issue? Certainly not…”
“I believe that these people are not stupid, instead they seek to create a brouhaha and muddy the waters in the climate change story. They seem to know exactly what they are doing and believe they can get away with it, because the public does not have the time, inclination, and training to discern what is a significant change with regard to the global warming issue.”
“The contrarians will be remembered as court jesters. There is no point to joust with court jesters. They will always be present. They will continue to entertain even if the Titanic begins to take on water. Their role and consequence is only as a diversion from what is important.
The real deal is this: the ‘royalty’ controlling the court, the ones with the power, the ones with the ability to make a difference, with the ability to change our course, the ones who will live in infamy if we pass the tipping points, are the captains of industry, CEOs in fossil fuel companies such as EXXON/Mobil, automobile manufacturers, utilities, all of the leaders who have placed short-term profit above the fate of the planet and the well-being of our children. The court jesters are their jesters, occasionally paid for services, and more substantively supported by the captains’ disinformation campaigns.”
