Please tell me how you stopped natural variation and made sure that all warming post 1950 was man made.
Obviously natural variation did not stop. And you choosing narrow time intervals to compare is obviously cherry picking. But...
...this tells us that CO2, CH4 (methane) and halocarbons (CFCs) are the largest radiative forcing factors. And isotopic analysis has shown that virtually every molecule above the pre-industrial 280 ppm CO2 and the 500 ppb methane and every molecule of CFCs are of human origin. Thus, humans are responsible for the observed warming.
SO please show me, by empirical evidence, the following;
1. How you stopped natural variation. According to the IPCC, the 1900-1950 rate of warming is natural and therefore the base rate of natural variation for our current time period given total solar output.
No one has ever claimed that natural variation has stopped. The temperature data plotted against several ranges of time which I displayed in the prior post clearly show that contemporary warming exceeds natural variation and that you are blatantly guilty of cherry picking.
2. How you concluded that all of the warming post 1950 is man made.
See above
3. What the result of a 120 ppm rise since 1890 has done
It is clearly displayed on the bottom of the graphic above: it has produced 2.29 W/m^2 of warming.
how you ruled out naturally occurring out-gasing of the oceans, due to warming
It has not been ruled out. It has been taken into account by all models. I hope you didn't think you were being clever.
and how you ruled out solar spectral shift.
Because that has also been taken into account. Note "Changes in solar irradiance" in the graphic above. And since power is an integration of the spectral curve, all spectral changes are included.
Still no empirical evidence to prove AGW has any merit...
And still you lie. To claim that the thousands of research papers that have been published on this topic, which are virtually ALL based on empirical data taken from the environment and which virtually ALL support AGW, contain no empirical evidence to support AGW indicates you're either incredibly stupid or incredibly dishonest

* and since you have never retracted your claim to be working on a PhD in atmospheric physicists while making a continuous series of 7th grade level mistakes (and worse), I would have to vote for BOTH DISHONEST AND STUPID
