I agree with your conversion to litres as 1.4E+21. I didn't bother to count all the zeros, but I assume they are correct. That being so, I agree with your figure of 5.92E+21 kJ for a 1degC rise.

Taking your second post you say that 0.5 kJ per day, a very large estimate as you say, would result in a rise of 1degC in 8.4 days. No dissent there.
If you take a fraction of a Joule, say 0.1J, that would result in a 1degC change in about 115 years. Which is not hugely different than that observed over the past 100 years.

Primarily for the benefit of others who post here, I have not posted this to make any political point nor to draw any specific conclusion other than what I posted above.
