The Science is not Settled
By David Siegel via www.ClimateCurious.com
What is your position on the climate-change debate? What would it take to change your mind?
If the answer is It would take a ton of evidence to change my mind, because my understanding is that the science is settled, and we need to get going on this important issue, that’s what I thought, too. This is my story.
More than thirty years ago, I became vegan because I believed it was healthier (it’s not), and I’ve stayed vegan because I believe it’s better for the environment (it is). I haven’t owned a car in ten years. I love animals; I’ll gladly fly halfway around the world to take photos of them in their natural habitats. I’m a Democrat: I think governments play a key role in helping preserve our environment for the future in the most cost-effective way possible. Over the years, I built a set of assumptions: that Al Gore was right about global warming, that he was the David going up against the industrial Goliath. In 1993, I even wrote a book about it.
Recently, a friend challenged those assumptions. At first, I was annoyed, because I thought the science really was settled. As I started to look at the data and read about climate science, I was surprised, then shocked. As I learned more, I changed my mind. I now think there probably is no climate crisis and that the focus on CO2 takes funding and attention from critical environmental problems. I’ll start by making ten short statements that should challenge your assumptions and then back them up with an essay.
1 • Weather is not climate. There are no studies showing a conclusive link between global warming and increased frequency or intensity of storms, droughts, floods, cold or heat waves.
2 • Natural variation in weather and climate is tremendous. Most of what people call “global warming” is natural, not man-made. The earth is warming, but not quickly, not much, and not lately.
3 • There is tremendous uncertainty as to how the climate really works. Climate models are not yet skillful; predictions are unresolved.
4 • New research shows fluctuations in energy from the sun correlate very strongly with changes in earth’s temperature, better than CO2 levels.
5 • CO2 has very little to do with it. All the decarbonization we can do isn’t going to change the climate much.
6 • There is no such thing as “carbon pollution.” Carbon dioxide is coming out of your nose right now; it is not a poisonous gas. CO2 concentrations in previous eras have been many times higher than they are today.
7 • Sea level will probably continue to rise — not quickly, and not much. Researchers have found no link between CO2 and sea level.
9 • No one has shown any damage to reef or marine systems. Additional man-made CO2 will not likely harm oceans, reef systems, or marine life. Fish are mostly threatened by people, who eat them.
10 • The Intergovernmental Panel on Climate Change and others are pursuing a political agenda and a PR campaign, not scientific inquiry. There’s a tremendous amount of trickery going on under the surface*.

Before i forget . . .
Because i’m a Mann-Made global warming skeptic and i hear the very anti-scientific phrase “settled science” ad nauseum, i see a lot of humor and irony in the following story regarding settled science suddenly being unsettled:
From the article:
Nineteen elements on the periodic table — including gold, cadmium, arsenic and aluminum — are getting their atomic weights adjusted.
The International Union of Pure and Applied Chemistry (IUPAC) announced that they’ve approved new weights for the elements thanks to more precise measurements and better calculations of the abundance of certain isotopes (atoms of an element with different numbers of neutrons).
Just when you thought all the science in the periodic chart was settled! Damn you atomic weight deniers!! Damn you!
