Atmospheric carbon dioxide is the primary source of carbon in life on Earth and its concentration in Earth's pre-industrial atmosphere since late in the Precambrian was regulated by photosynthetic organisms and geological phenomena.
At about 55 km, the mesosphere begins. In the mesosphere, the temperature decreases with height again, because there is very little ozone to warm up the air. Finally, the mesopause divides the mesosphere from the thermosphere, which is the section of the atmosphere higher than 90 km. In this region, the temperature increases again. This time, it is molecular oxygen (O2) that causes the temperature increase.
Global Warming Causes Less Hurricanes. It is not just warm water which causes hurricanes. It is the temperature difference between the ocean surface and the upper atmosphere. The higher that temperature difference, the more hurricanes will form, and the stronger they will be. Global warming models all agree that the temperatures will rise more in the upper atmosphere than at the surface.
