That's essentially tossing in a fudge factor to get earth's average temp to match the "it's only S-B" theory.
To be taken seriously, a theory has to explain the current fast warming.
It could be claimed that the albedo feedback cycle explains all the warming.
However, that doesn't explain why we haven't seen such cycles in the recent past.
And, running the numbers, albedo feedback only explains about 10% of the current warming. Left to itself, albedo feedback would fade out. Albedo feedback just reinforces the greenhouse gas effects.
How are you defining "fast warming"? ... a single degree in 45 years? ... that's pretty weak ... we get a single degree warming
per hour every morning it's not raining ... and there's nothing in SB that wouldn't confirm this ... just we have to add CO
2 to the atmosphere by a power of 4 more to raise temperatures ... or are you claiming we're not adding CO
2 fast enough? ...
Do you know what albedo is? ... solar radiation that is reflected back into space without being absorbed, and without increasing temperature on the surface ... very roughly 30% of the 1,360 W/m^2 ... you have this "feedback" backwards ... warmer surface temperatures raise humidity 7% per degree ... which causes an increase in average cloudiness ... which
increases albedo, which then cools the Earth's surface ... this is a negative feedback ... one of the agents that gives us a robust climate ...
Do you have an alternative to a "fudge factor" in SB? ... it's a ratio, like in trigonometry ... we use them all the time in mathematics ... 1 is transparent, 0 is opaque ... do you have a better way? ... this is something I'm looking for, the numerical relationship between our "fudge factor" and CO
2 concentrations ... we can figure the emissions in a free market, easy, but what will that do to radiative forcing? ...
We can test SB in the lab ... and we're fully aware of it's shortcomings ... but everything here in below 10,000K ... so SB works fine ...
