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 on earth, including China and …

‘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 decades from now. What a …

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 generally warmer world will be …

‘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: It's true that the earth …

‘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: Given the fact that human …

‘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 driver. Answer: While there are …

‘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 rise. Answer: When viewed coarsely, …

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 "proof" in science -- that …

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 anywhere from 9% to 30% …
