Exploring alternative fuels for aviation use and was wondering whether using LNG instead of jet fuel would be a better alternative than using Hydrogen combustion or Fuel Cells.
In the stratosphere, the increase in CO2 leads not to a warming but to a cooling.
Water vapor hardly plays any substantial role in that process.
Alexey Danilov , thanks for the answer. But isn't water vapour a more potent greenhouse gas than CO2? I was of the impression that water vapour released into the stratosphere stays up there far longer and would thus have a more potent heat trapping effect than it does in the troposphere. Would greatly appreciate your help on this!
Interesting thinking!
Maybe these gases would not stay long enough in the stratosphere to have an effect on the temperature where we are.
On average, water vapors probably account for about 60% of the warming effect. However, water vapor does not control the Earth’s temperature, but is instead controlled by the temperature. The greenhouse effect that has maintained the Earth’s temperature at a level warm enough over several millennia is controlled by non-condensable gases like carbon dioxide.
