The OP is a canard. While GIGO assails Anthony Watts for being a hypocrite and a slinger of mud and arrows, he and his ilk are happy to resort to ad-hominem attacks in attempting to discredit skeptics, who by and large agree the earth has warmed in the last 100 years, but disagree there is irrefutable proof man has caused most or all of this warming.
The complex factors that create our global climate (and warming) remain poorly understood. Indeed, virtually all models that predict catastrophic causes from increased CO2 emission rely on a speculative, unproven (some might say fictitious) “multiplier effect” on water vapor. Otherwise, the logarithmic diminishing effect on climate of increased CO2 emissions can’t be accounted for. That is, each additional amount of CO2 warms the climate far less than the other CO2 did before it. Without the invention of a multiplier effect, the dire predictions intended to shock and scare people into action fall flat on their faces.
The Skeptical Science site that GIGO links to most frequently is decidedly pro-AGW. That is, it generally advances the viewpoint that man has caused all or most of recently observed warming, and consists of a nicely blended mixture of facts, propaganda, and omission. Yet GIGO likes to pretend this site is objective, while labeling Anthony Watts a “denier.”
Anthony Watts’s site is more transparent than many of the pro-AGW sites out there, including your favorite pet site “Skeptical Science.” Watts generally makes very few bones about what his positions are (and why) unlike that site. The fact that GIGO and his ilk deplore Watts while ascribing to the views of advocates-in-scientists-clothing, such as James Hansen and Michael Mann, is amusing.
There remain many important, unanswered questions about our climate. Is current warming simply part of a much longer scale trend dating to the Little Ice age? Does the water vapor feedback effect really exist as theorized by CAGW proponents? What kind of dampening effect does increased CO2 absorption by plants have? What other feedbacks (dampening or positive) are we not yet aware of, or have misunderstood, or have improperly quantified?
GIGO would like you to ignore these questions, because the science is “settled.” What I think that GIGO and many on this board do not appreciate is that the reason that people—sorry, “deniers”—are hostile to climate change scientists is that many of these men and women have abdicated their spots on the sidelines. They are instead performing research and publishing while actively trying to promote political agendas and advocate for outcomes. It is politics, not science. I believe GIGO understands this, as he appears quite willing to level this charge against the very “deniers” that he loathes. Hilariously, GIGO fails to appreciate that this exact behavior is being engaged in by bad actors on the side that advocates the belief that man is in the process of causing catastrophic climate change.
Politics, not science. Hence the vitriol, the recriminations, and everything else. And as far as politics go, I’d rather not see sweeping changes enacted on me, the United States, or anyone else based on what is still little more than glorified speculation that man is going to cause dire warming in the next century and beyond. This, I suspect, is the underlying root of Scylla’s skepticism, as it is mine.
