A letter sent to the NZ Herald. Hope they publish it.
Sir,
Your leader of August 7 headed Seize chance to lead way on climate change, on one level, is easy to support, but on different grounds, for those assumed in your leader are spurious. We must take a lead, indeed—let us be the first to examine the need to respond to climate change.
No matter how far we go along the path towards action, no matter how many people concur that action must be taken, even on marketing grounds, no matter how the arguments for action pluck at our heart strings, no matter that we all want to save the planet, yet if there are no grounds for action, it will be wasted: the taxpayers’ money wasted, the voters’ living spent.
At the risk of sounding repetitive—even a bit shrill, evidence of the catastrophe said to be building around us is yet to arrive, at the very time of decision when its presence is most important. Global air temperatures are recently level, even declining. Even the long-term trend in air temperature is within natural limits. Sea levels are rising no faster than they have for centuries, sea temperatures are not rising, sea ice levels are within normal limits and Tuvalu has still not been evacuated, though an oceanic incursion has been threatened since the 1980s. Glaciers are mentioned only when one is found with pieces conveniently missing; plenty are growing, but unreported. We’re yawning.
The only reason to believe future temperatures will be ruinous are computer models of the climate. But as everyone knows, they are driven in every decisive parameter by human knowledge and its imperfections, not by the climate. They do not deal properly with clouds, which by themselves are capable of overwhelming any temperature change attributed to carbon dioxide or the lack thereof. They do not deal properly with a list of things. They are not reality and they constitute no sort of evidence whatsoever.
So—what is the evidence? Not the propaganda—the evidence!
