It increases, reaching as high as 2,000 degrees Celsius in the upper Thermosphere. As the atmosphere thins, it takes less and less energy to cause changes in temperature. Between ionizing radiation and the direct exposure to the sun's rays (and radiation), the outer atmosphere starts to heat up again, absorbing some of the heat before it reaches the lower atmosphere and surface.

I'm pretty sure they decrease the higher up you go through the Earth's atmosphere. Most of the heat is at the Earth's surface. It gets colder as you get nearer to outer space.

In the thermosphere - which is directly above the mesosphere and below the exosphere - the temperature actually increaseswith height due to the low air density.
