One More Time: How To Talk to A Climate Skeptic

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:

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

a.       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

b.       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

c.        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

a.       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

b.       Prediction is impossible

§         We can't even predict the weather next week

§         Chaotic systems are not predictable

c.        We can't be sure

§         The modelers won't tell us how confident they are in the models

§         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

a.       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

b.       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

§         Today's warming is just a recovery from the Little Ice Age

c.        It's not caused by CO2

§         Why don't they ever mention water vapor?

§         Water vapor's greenhouse effect overwhelms CO2

§         There is no proof that CO2 is causing global warming

§         Mars and Pluto are warming too

§         CO2 lags, not leads

§         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

a.       The effects are good

§         A warmer world will be better

b.       The effects are minor

§         Any ice melt will just go into groundwater

c.        Change is normal

5.       Climate change can't be stopped

a.       Too late

§         Kyoto is ineffective

b.       It's someone else's problem

§         Why should the U.S. join Kyoto?

§         The U.S. is a net CO2 sink

c.        Economically infeasible

§         Action on global warming is suicide
