‘Climate scientists dodge the subject of water vapor’–No, they really don’t

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Climate scientists never talk about water vapor -- the strongest greenhouse gas -- because it undermines their CO2 theory. Answer: Not a …

‘We are just recovering from the LIA’–Why should we expect this to happen?

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Today's warming is just a recovery from the Little Ice Age. Answer: This argument relies on an implicit assumption that there is …

‘The CO2 rise is natural’–No skeptical argument has been more definitively disproven

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: It's clear from ice cores and other geological history that CO2 fluctuates naturally. It is bogus to assume today's rise is caused …

‘Natural emissions dwarf human emissions’–But emissions are only one side of the equation

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: According to the IPCC, 150 billion tonnes of carbon go into the atmosphere from natural processes every year. This is almost 30 …

‘Climate is always changing’–That doesn’t mean it isn’t different today

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Climate has always changed. Why are we worried now, and why does it have to be humans' fault? Answer: Yes, climate has …

‘The null hypothesis says warming is natural’–An inappropriate test, and one that would fail anyway

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Natural variability is the null hypothesis; there must be compelling evidence of an anthropogenic CO2 warming effect before we take it seriously. …

‘Volcanoes emit more CO2 than humans’–Not even close …

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: One decent-sized volcanic eruption puts more CO2 in the atmosphere than a decade of human emissions. It's ridiculous to think reducing human …

‘Mars and Pluto are warming too’–No they aren’t — and what if they were?

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Global warming is happening on Mars and Pluto as well. Since there are no SUVs on Mars, CO2 can't be causing global …

‘Global warming is part of a natural cycle’–This idea is one short step above appealing to magic

(Part of the How to Talk to a Global Warming Skeptic guide) Objection: Current warming is just part of a natural cycle. Answer: While it is undoubtedly true that there are natural cycles and variations …
