The General Assembly is set to hear a presentation from a “scientist” claiming that “Science is Under Assault.” Go through his presentation slides here, and see for yourself that he is merely setting the stage for policy makers to actually disregard good science (since they’re already disregarding economics, logic, and common decency). It appears that WRAL @NCCapital will carry a live stream of the talk.
Let me pull out one part of this guy’s presentation and rebutt it. He is making the argument that focusing only on the past 500 years of ice core data in Greenland is what is raising the alarm on climate change, but when you look at the past 1000+ years, the picture looks different: the climate was warmer 700 years or so ago, then cooled off. What a hoax to think that we’re warming the climate, right? Wrong. Geologists have known for a long time that we are currently in an inter-glacial cycle, and those glacial cycles have a 20,000 year period, and have historical occurred in sets of 5 periods. We’ve had 4 of those periods. What we don’t know is how the industrial revolution and the current use of fossil fuels that removes minerals from within the crust and places them in the atmosphere will affect the inter-glacial cycle. And keep in mind that the population has grown quite dramatically in the past 1000+ years, so a change in climate will have an extreme ripple effect on us.
It’s actually the deductive reasoning of science that leads us to know quite reliably that human activity is influencing the climate. And it’s good public policy to plan for the impact of that change.
