- TL;DR Summary
- Assume a "worst" case scenario of 6 C global warming. Will the air pressure at high altitudes increase significantly due to a change in scale height of the atmosphere and other factors?
Increases in global temperature change affect the tree line and presumably comfortable habitability via temperature, and average air pressure associated with weather patterns. That's not what I mean. I'm thinking a 1/50 increase in kelvin temperature might increase the scale height of Earth's atmosphere by a comparable factor - from, say, 8 km to 8.16 km. Increases in the volume of the oceans should also push up the atmosphere from below. However, the density of air molecules starts off less because it's hotter at sea level. Then there's the wild card of how much of each gas dissolves into the oceans at different temperatures and pH levels. Has anyone worked through all the angles to determine the net effect on the average of all air density at any given altitude above the geoid?
