First of all, global warming not only is a well documented fact, but the earth's average temperature would be about 40 degrees colder, F, if not for global warming.
If you substituted the phrase green house gas for the phrase global warming your post would be more accurate. If all GHG's including water were gone, there would not be anything to prevent the surface from losing a great deal of radiation. If I remember right, the calculation is that the earth would be around -40 ℃. Is that what you intended?

You have a point in that modern global warming is referring to the increase from the stasis point the planet has had for hundreds of millions of years.
And the warming of 40 degrees F from the theoretical temperature if there was no greenhouse gases, should not be confused with current warming, even though that was past global warming to get to the temperature the atmosphere was for hundreds of millions of years.
But even that is a generalization, but cause we also know the historic value is really the average of a 120,000 year long fluctuating cycle. But that is not really important, since we now are talking about a very fast, new, and different change being cause by man's release of hundreds of millions of years worth of sequestered carbon and solar energy, through the burning of fossil fuel. We don't even have to talk about the change in upper atmosphere radiation capability, when you simply consider all that sequestered, fossil, ancient solar energy being release so quickly.
