Of the TOTAL greenhouse effect of 33 degrees C maybe 10% is caused by CO2 and of that amount only 1/3 is at most from burning fossil fuels; so maybe today the total effect at 400 ppm is 1.1 degree C from burning fossil fuels. Natural cycles account of the rest which is 97% and I’d say that is conservative its probably more. The current pause is 100% natural.
What percentage of zero warming is Mann-made?
- Mostly Mann-made
- Equally Mann-made and natural
- Mostly natural
- Not interested in troposphere temperatures. Only do Urban Heat Island temperatures
