“But ABC”

Reducing climate change to Anything But Carbon.

Examples

[MOO] We have had this climate before may times over the span of 10,000 yrs. There is no emergency. Just solar maximum and minimums and natural earth cycles. Co2 is not a problem right now.

[STEVET] Read my lips: Climate change is a common planetary phenomenon that has nothing to do with people and cars.

[ALT-CENTER] Historically, the Earth has never had a quasi-stable state ~2*C warmer than pre-industrial temp, the system ALWAYS warms.

[DR PHILIP K] Only one idiot thinks human input of [CO] is significant. Every 100,000 years Mother Nature unleashes hell.

[KENNETH] Every day the CO2 in forests fluxes from 300 ppm in the heat of the day to 600 ppm in the middle of the night/before dawn.

Objections and Replies

(Cause) CO2 does not cause temperature rises.
Reply. It influences solar radiation, which in turn affects temperature.

(Climate changes) Climate doesn’t stay the exact same forever—
Reply.

(Coolant) CO2 is used as an industrial coolant—
Reply. Because it’s cheap, risk-free, not because it’s efficient.

(Cyclical) We don’t know how much is our fault & how much is—
Reply. The A in AGW is likely 93%–123% of the observed 1951–2010 change.

(God) God controls the weather
Reply. But She does not control climate.

(Night and Days)

(Ozone)

(Pluto) There’s global warming on Pluto

(Teh Sun) No one recognizes the single biggest contributor: solar output—
Reply. I’m quite sure physicists heard about it.

(Volcanoes)
Reply. Every single day humans release a Mt Pinatubo eruption’s worth of CO2.

(Water Vapor) —
Reply. Water vapor fluctuates daily whereas CO2 used to vary on geological times scale.

Notes

{Second Law} There are lots of arcane discussions about the Second Law of thermodynamics. I suggest you stay away from them and defer to physicists. It takes expertise to diagnose misunderstandings.
