I asked a group of climate skeptics/deniers to answer the following, asking people to focus on what they believe and not how scientists are wrong:
• Do you believe that the climate is changing? How fast? °C/decade is an OK unit.
• If so, what are the causes of the climate change? (Natural is not an answer, please explain the exact natural process.)
• Is climate change serious yet? Is it likely to be this century?
• Which sources of information do you trust to find errors in your thinking?
I have received the following answers so far:
Scientists are lying, here is a tabloid author saying so. I don’t know if Earth is warming, but if so, the cause is natural. Scientists are speaking beyond their expertise. I don’t like the solutions. Earth could be cooling. The ocean is giving off carbon dioxide to the atmosphere right now, also warmth. Scientists lie, look at climategate. If you weren’t so fixated on your sources (I’ve identified my sources as major reports written by organizations like National Academy of Sciences), you would know more. The solutions are too expensive. This book, which I intend to read some day, explains where you are wrong. There are scientists on all side, eg, this statistician. Scientists don’t actually agree that 2010 is the hottest year on record. Scientists disagree on climate change. How do scientists know what is the optimum temperature (for what is unspecified)? How can you say that you know what is happening to the climate because no one knows, I certainly don’t. Scientists use consensus when they don’t have good data. Scientists who accept the consensus on the climate are closed minded. The solutions will destroy the economy.
So far none seem to understand that, with the exception of the person who somehow has the ocean releasing both heat and carbon dioxide, all have failed to clarify what they believe, and if they have reason to believe it. I originally asked the questions so that they could see whether they agree with one another, but so far, they are stuck on “scientists are wrong” and none of the rest of us know what they believe.
Climate skeptics/deniers, can you do better?
