'Why should the U.S. join Kyoto when China and India haven't?'

China and India have joined Kyoto, they just have different obligations, as is morally appropriate

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Why should the U.S. join Kyoto while India and China haven't? Answer: The U.S. puts out more CO2 than any other nation …

‘Kyoto is a big effort for almost nothing’–Kyoto is only in its first phase

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: The Kyoto treaty, even if fully implemented, would only save us about a tenth of a degree of future temperature rise many …

'What's wrong with warmer weather?'

The problem is not how high the temperature may go, but how fast it is changing

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: The earth has had much warmer climates in the past. What's so special about the current climate? Anyway, it seems like a …

‘It’s the sun, stupid’–Very bright, yes, but not getting brighter

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: The sun is the source of warmth on earth. Any increase in temperature is likely due to changes in solar radiation. Answer: …

‘Historically, CO2 never caused temperature change’–Not so

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: In the geological record, it is clear that CO2 does not trigger climate changes. Why should it be any different now? Answer: …

‘Geological history does not support CO2’s importance’–Just not true

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Over the last 600 million years, there hasn't been much correlation between temperatures and CO2 levels. Clearly CO2 is not a climate …

‘CO2 doesn’t lead, it lags’–Turns out CO2 rise is both a cause and an effect of warming

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: In glacial-interglacial cycles, CO2 concentration lags behind temperature by centuries. Clearly, CO2 does not cause temperatures to rise; temperatures cause CO2 to …

'There is no proof that CO2 is causing global warming'

There is no proof in science, but there are mountains of evidence

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Correlation is not proof of causation. There is no proof that CO2 is the cause of current warming. Answer: There is no …

'Water vapor accounts for almost all of the greenhouse effect'

Water vapor is indeed a powerful greenhouse gas, but there is plenty of room for CO2 to play a role

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: H2O accounts for 95% of the greenhouse effect; CO2 is insignificant. Answer: According to the scientific literature and climate experts, CO2 contributes …
