How to Talk to a Climate Skeptic
Below is a complete listing of the articles in "How to Talk to a Climate Skeptic," a series by Coby Beck containing responses to the most common skeptical arguments on global warming. There are four separate taxonomies; arguments are divided by:
• Stages of Denial,
• Scientific Topics,
• Types of Argument, and
• Levels of Sophistication.
Individual articles will appear under multiple headings and may even appear in multiple subcategories in the same heading.
Stages of Denial
1. There's nothing happening
1. Inadequate evidence
• There is no evidence
• One record year is not global warming
• The temperature record is simply unreliable
• One hundred years is not enough
• Glaciers have always grown and receded
• Warming is due to the Urban Heat Island effect
• 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
• Some sites show cooling
3. No consensus
• Global warming is a hoax
• There is no consensus
• Position statements hide debate
• Consensus is collusion
• Peiser refuted Oreskes
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
2. Prediction is impossible
• We can't even predict the weather next week
• Chaotic systems are not predictable
3. We can't be sure
• Hansen has been wrong before
• If we can't understand the past, how can we understand the present?
• The scientists aren't even sure
• They predicted global cooling in the 1970s
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
• Greenland used to be green
• Global warming is nothing new!
• The hockey stick is broken
• Vineland was full of grapes
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
• The null hypothesis says global warming is natural
• 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
