Anybody has a guess of what will be Average US Temperature by 2020?
No idea.
On the other hand, that can be misleading.
The surface temperature isn't always accurate of the overall temperature. Bear these things in mind:
As the overall temperature rises, water expands, which pushes it up on the shore line and makes it easier to evaporate by making it more shallow and spreading the surface of the water mass.
Thus, more water will enter the air, creating more moisture and heavier rains, likely decreasing the actual surface temperature (and increasingly high snow falls).
Also bear in mind that as the overall temperature of the Earth climbs, things like the polar ice caps will melt, releasing previously stagnant ice (and very cold water) into the oceans, lowering their temperature and having an impact on the Earth's surface temperature as well.
In other words, the surface temperature of the Earth can decrease dramatically, giving the false impression that the Earth is cooling when in reality, the overall temperature is increasing.
