no. The heat from the sun has to pass through our atmosphere (which is not uniform) and be absorbed by the earth (not uniform) the earth will absorb and reflect the heat depending on what the material is, how light or dark it is, and water will absorb heat differently than land mass. Black ashphalt will create more heat than grassy fields. Add to that the fact that we have winds and currents that take the heat and move it around a lot, blowing in cold air from the north, or moving cool night air from one region or hot air from a daytime region. This is basic science here.
