Climate on the planet has changed for the past billion years.
The graph in th OP represents about 10 years.
Extrapolation is ridiculous.
I dont think you are quite getting the concept of the diagram. it is a massively simplified description of the current equilibrium of the climate. it is so generic that it probably describes all of the current interglacial period, although I have no real faith in the accuracy of any of the numbers.
as others have brought up before, it does not incorporate the effects of full sunlight, dusk, night and dawn. nor does it describe the different latitudes and the large change in radiation according to temperature (it varies according to the fourth power{T measured in Kelvins}). averaging the sunlight input, ground temperature, convection rates, evaporation and humidity rates, as well as ignoring ocean currents and Hadley cell type air currents, make for a description that doesnt match anywhere on earth but it at least gives us something to start with.
one thing I find interesting is that the tropics remain ice free and at roughly the same temperature even in iceage periods. personally I think the bulk of our research should be done on understanding the tropics because that area is what powers all the climatic processes.
Have you read any of the work lately, bolsterd by actual experimentation that prove that an earth with an atmosphere that contains no radiative gasses would be warmer than an earth with an atmosphere that contains with radiative gasses?
