Non-CO2 GHGs are rising 3.6x faster than CO2 itself

3. And of course Water Vapor in the the high atmosphere is and even more effective GHG

All of these "trace" gases are warming the atmosphere and increasing the water vapor content which greatly amplifies the green house effect.

I could not find the reference but i recently read that much less of this high water vapor is frozen than previously thought. Frozen or crystallized water vapor will reflect some of the incoming light energy and lowers global warming. But if the high vapor is not in crystal form then it lets the suns energy in and traps the heat and is a worse GHG.

I do not think that I have ever read one of these stories where the phrase "worse than previously thought" or the equivalent was not used.
