How to Talk to a Climate Skeptic: Responses to the most common skeptical arguments on global warming

‘Chaotic systems are not predictable’–Sure, but who says climate is chaotic?

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Climate is an inherently chaotic system, and as such its behavior can not be predicted. Answer: Firstly, let's make sure we define climate: an average of weather …

‘We can’t even predict the weather next week’–But weather is not climate

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Scientists can't even predict the weather next week, so why should we believe what some climate model tells us about 100 years from now? Answer: Climate and …

‘Aerosols should mean more warming in the south’–More North. Hemisphere warming is well-understood

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Scientists claim that global warming from greenhouse gases is being countered somewhat by global dimming from aerosol pollution. They even claim that aerosol pollution caused the cooling …

‘Climate models are unproven’–Actually, GCM’s have many confirmed successes under their belts

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Why should we trust a bunch of contrived computer models that have never had a prediction confirmed? Talk to me in 100 years. Answer: Given the absence …

‘Models don’t account for clouds’–Clouds are complex and uncertain, but unlikely to stop warming

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Clouds are a large negative feedback that will stop any drastic warming. The climate models don't even take cloud effects into account. Answer: All of the atmospheric …

‘Peiser refuted Oreskes’–In a poor piece of work that has been retracted by its author

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Sure, Oreskes found no one bucking the consensus, but her paper was refuted by Benny Peiser, who did the exact same survey and found very different results. …

How to Talk to a Climate Skeptic: Responses to the most common skeptical arguments on global warming

‘Consensus is collusion’–Is climate science maturing, or should we reach for our tinfoil hats?

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: More and more, climate models share all the same assumptions -- so of course they all agree! And every year, fewer scientists dare speak out against the …

‘Position statements hide debate’–True enough, but that is not the whole picture

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: All those institutional position statements are fine, but by their very nature they paper over debate and obscure the variety of individual positions. The real debate is …

‘There is no consensus’–If this is not consensus, what would consensus look like?

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Climate is complicated and there are lots of competing theories and unsolved mysteries. Until this is all worked out, one can't claim there is consensus on global …
