You know ’em:

• There’s been no warming for 15 years
• The Sun’s responsible
• CO2 is a trace gas in atmosphere and therefore can’t have anything to do with warming
• It’s been warmer before
• Climate is changing, but it’s not people
• Climate is changing, but it won’t be too bad, so it doesn’t matter
• Climate change happens all the time, so what’s the big deal?
• Temperature always causes CO₂ to increase, never the other way around
• We can always reduce emissions later, if it proves out that it’s a problem
• We cannot afford to reduce emissions now, and if we need to mitigate later, that’s not something which has a present day cost
• The climate models disagree with observations
• It’s a collectivist conspiracy
• Loss of Arctic sea ice is an illusion
• CO₂ is increasing, but people have nothing to do with it
• Climate change as an idea is a vast conspiracy to get more people on the public dime
• I can’t afford to pay more for carbon-based fuels
• Climategate proved scientists can’t be trusted
• Climate change is a new idea invented by Al Gore and climate scientists invented the theory because they wanted bigger grants
• I want to drive my SUV no matter what
• Why should I care about next generations. No one saved any buffalo for me!
