The IPCC states that all warming prior to 1950 is considered natural variation or not man caused and that warming post 1950 is all man caused. I still don't know how they pulled off stopping natural cycles.
Below are those two rates of warming. There is no statistical difference between the two. If we consider natural variation, CO2's influence is zero.
The two rates of warming are almost indistinguishable from one another. Their total difference is less than 0.03 deg C
I then ask alarmists to 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.
2. How you concluded that all of the warming post 1950 is man made.
3. What the result of a120ppm rise since 1890 has done, how you ruled out naturally occurring out-gasing of the oceans, due to warming, and how you ruled out solar spectral shift.
I never get a legitimate answer. lots of cut and paste garbage but little more.
