1. There's nothing happening

        === 1. Inadequate evidence ===
               * There is no evidence
                   - Isotopic Signature Rasmus Benestad
                   - NASA Earth Observatory by Holli Riebeek NASA
               * One record year is not global warming
                   - What's the Difference Between Weather and Climate? NASA
               * The temperature record is simply unreliable
               * One hundred years is not enough
                   - List from World Data Center for Paleoclimatology NCDC/NOAA

               * Mauna Loa is a volcano
               * The scientists aren't even sure
        === 2. Contradictory evidence ===
               * It's cold today in Wagga Wagga
               * Antarctic ice is growing
               * The satellites show cooling
               * What about mid-century cooling?
               * Global warming stopped in 1998
               * But the glaciers are not melting
               * Antarctic sea ice is increasing
               * Observations show climate sensitivity is not very high
               * Sea level in the Arctic is falling

        3. No consensus NOt sure how to do internal link http://www.realclimate.org/index.php?p=80
               * Global warming is a hoax

  == 2. We don't know why it's happening ==
        == 1. Models don't work == 
               * We cannot trust unproven computer models
               * The models don't have clouds
               * If aerosols are blocking the sun, the south should warm faster
               * Observations show climate sensitivity is not very high

               * We can't even predict the weather next week
               * Chaotic systems are not predictable

               * The scientists aren't even sure

  3. Climate change is natural
        1. It happened before
               * It was warmer during the Holocene Climatic Optimum
               * The medieval warm period was just as warm as today

        2. It's part of a natural change
               * Current global warming is just part of a natural cycle
               * Mars and Pluto are warming too
               * CO2 in the air comes mostly from volcanoes

               * Climate is always changing
               * Natural emissions dwarf human emissions
               * The CO2 rise is natural
               * We are just recovering from the LIA
        3. It's not caused by CO2
               * Climate scientists dodge the subject of water vapor
               * Water vapor accounts for almost all of the greenhouse effect
               * There is no proof that CO2 is causing global warming
               * Mars and Pluto are warming too
               * CO2 doesn't lead, it lags
               * What about mid-century cooling?
               * Geological history does not support CO2's importance
               * Historically, CO2 never caused temperature change
               * It's the sun, stupid
  4. Climate change is not bad
        1. The effects are good
               * What's wrong with warmer weather?
        2. The effects are minor
        3. Change is normal
  5. Climate change can't be stopped
        1. Too late
               * Kyoto is a big effort for almost nothing
        2. It's someone else's problem
               * Why should the U.S. join Kyoto when China and India haven't?
               * The U.S. is a net CO2 sink
        3. Economically infeasible
               * Climate change mitigation would lead to disaster
