Hi ,

to start ive been running a climate prediction programe at home useing BOINC

http://climateprediction.net/ , its aim is to repeat weather patterns from past periods and see how there stack up agianst the real world IE : see if the input actually works , not just to get a desired out come IE ; prove gobal warming .

these models take into account the radiative forcing of water vapor , the sun , CO2 , CH4 , N2O , CFC-11 and CFC-12 also cosmic rays for the effects on cloud formation .

You seemed interested in calculating the effects of these gases so heres some help .

Table 1. Expressions for Calculating Radiative Forcing*

Trace Gas Simplified Expression

Radiative Forcing, ΔF (Wm-2) Constant

CO2 ΔF = αln(C/Co) α = 5.35

CH4 ΔF = β(M½ - Mo½) - [f(M,No) - f(Mo,No)] β = 0.036

N2O ΔF = ε(N½ - No½) - [f(Mo,N) - f(Mo,No)] ε = 0.12

CFC-11 ΔF = λ(X - Xo) λ = 0.25

CFC-12 ΔF = ω(X - Xo) ω = 0.32

*IPCC (2001)

The subscript "o" denotes the unperturbed (1750) concentration

f(M,N) = 0.47ln[1 + 2.01x10-5 (MN)0.75 + 5.31x10-15M(MN)1.52]

C is CO2 in ppm, M is CH4 in ppb

N is N2O in ppb, X is CFC in ppb

Co = 278 ppm, Mo = 700 ppb, No = 270 ppb, Xo = 0

from

www.esrl.noaa.gov/gmd/aggi/i left one out water vapor , water vapor is considered a feedback not a forcing , one reason is more water vapor equals more clouds , clouds reflect the sun and actually have a cooling effect and so tend to even out .

what i dont understand is how if its all a con how so many and i guess its at least 90% of scientist , reserchers could al be be so wrong , i know people talk as thou it s religion but religions dont need facts or data , science does otherwise it just doesnt work , it has to deal in the real world .

oh and Gordan for a stir , how can the moon affect the tides think about it the sun has a much stronger gavitational field its only logical thats what moves the oceans , lol
