I was looking at Nir Shaviv’s site Science Bits and came across an interesting paragraph.
According to the IPCC (AR4), the solar irradiance is responsible for a net radiative forcing increase between the Maunder Minimum and today of 0.12 W/m2 (0.06 to 0.60 at 90% confidence). We know however that the Maunder minimum was about 1°C colder (e.g., from direct temperature measurements of boreholes – e.g., this summary). This requires a global sensitivity of 1.0/0.12°C/(W/m2). Since doubling the CO2 is thought to induce a 3.8 W/m2 change in the radiative forcing, irradiance/climate correlations require a CO2 doubling temperature of ΔTx2 ~ 31°C !! Besides being at odds with other observations, any sensitivity larger than ΔTx2 ~ 10°C would cause the climate to be unconditionally unstable (see box here).
Clearly, the IPCC scientists don’t comprehend that their numbers add up to a totally inconsistent picture. Of course, the real story is that solar forcing, even just the irradiance change, is larger than the IPCC values.
Make sure that you look at the box at Ice Core Truth where he shows that any value for climate sensitivity above 10°C for a doubling of CO2 produces an unconditionally unstable climate. That is the crux of the matter.
Now for a bit of speculation. Why aren’t the alarmist numbers internally consistent? I suspect they are cooking the books.
And speaking of books. There is one on that very subject:

Any global warmmonger who doesn’t mention the Sun is either stupid or lying. (yes, I’ve stopped being polite to them. I don’t like evangelicals of an ignorant religion)
It never fails to make me laugh, I’ll engage a global warmmonger and ask him about the Sun and he’ll act as if I’m the idiot for wanting to discuss the Sun when discussing the temperature of the Earth.
It’s funny but dangerous.
And exactly why it’s so fitting for The Funniest End of Civilization Ever. (soon with exclamation points!)
I currently reading a very interesting book “Heaven and Earht” by one of Australia’s leading scientist’s, Ian Plimer. http://bravenewclimate.com/2009/04/23/ian-plimer-heaven-and-earth/
If you want a clear description of the problems with any and all theories that are lumped together as “Anthropomorphic Global Warming,” please buy this book. Heavy footnoted, but that just proves the validity of the points that he makes.
Of course they’re cooking the books. It’s not about CO2 or climate change. It IS all about control.
Like cas above, I’m in the midst of reading Plimer’s Heaven and Earth and Dr. Plimer is constantly pointing out that atmospheric CO2 concentration has no connection with global temperature. To insist that it does is flailing a dead horse.
Here is the Amazon link to Plimer:
