I have to admit, I am in the sceptics camp.
However, I do not trust Lord Monckton any more than I would trust Al Gore.
I am willing to change my mind about MMGW if someone can explain it to me.
I certainly am a layman (but willing to learn.. my math might be off).
My main question is:
Why is all the focus of the MMGW camp on CO
2?
All the charts I've seen show that CO
2 never was the driving force behind temperature change. CO2 increase always lagged several hundred years behind temperature.
To me, it looks like a clear violation of causality to claim CO
2 is responsible.
The IPCC AR4 says in it's Dumb-People-Summary
[..]The combined anthropogenic RF is estimated to be +1.6 [–1.0, +0.8] W m–2, indicating that, since 1750, it is extremely likely that humans have exerted a substantial warming influence on climate. [..]
The Sun chunks out enough energy that roughly 341W/m
2 reach the upper atmosphere and 163W/m
2 reach the surface on average.
In other words the IPCC calculated MM warming effect adds 0.9% to the sun's. Now factor in that for a 1% increase in energy we get a tiny increase in temperature (if I didn't get the dreaded physics of Mr Boltzmann wrong: E = s * T
4. Since I am only interested in the
change that human made warming effect has i can omit any constants and focus on the difference between temperatures with and without human RF.)
Putting in the numbers, our glorious effect on temperature is an increase of approx. 0.25% .
The globe has warmed by (I'm willing to change that number if someone has better sources) 1 degree in the last century.
How will changing CO
2 output change anything here?
