[Ghost of Philip Marlowe]

There is a much easier method.

Most people who support the lie of APG base their temperature claims on the IPCC data.

Simply ask them how they made the measurements.

Most do not know.

I’ve yet to discuss this with someone who understands how woefully inadequate the measurements were.

Or ask them what is the “correct” global temparature

Or ask them shouldn’t we concentrate on the gases that are the greatest contribution to warming. And when they say yes, ask them how we are going to control water vapor.

Yes, they don’t realize the rug has been pulled out from under them because of climategate.

The IPCC, NASA’s GISS, most of the scientists in those institutes, were all involved with generating bad predictions based on bad data which they put into bad models with bad programming.

Everything thing AGW is based upon is hopelessly corrupted.

or.....After the last ice age ended, the earth warmed. Was THAT due to humans? I LOVE looking at their faces at that point.

After which, I add: Woolly mammoth flatulence, perhaps?
