This is also a topic I mention here from time to time, knowing it will get down voted into oblivion. Even HN suffers from group think on certain things.
You can't just focus on CO2 when water is a far more powerful greenhouse gas, and we've seen contrails have large short term effects on the weather.
- hgomersall 3y agoI think the problem might be that in the wrong hands the issue is used to muddy rather than enhance the discussion. Generally the problem with focusing on water as "a greenhouse gas" is that there is limited scope for doing anything about it. Indeed, it's likely part of various feedback systems so acts as a confounder rather than an independent variable. Of course we should consider the impact of dumping lots of high altitude water into the atmosphere, but we should primarily consider the impact of dumping lots of co2 and methane since those are a much bigger slice of the anthropogenic delta.

I've seen the effects of stopping air travel with my own eyes. What if it really is the dominant driver, and all the CO2 fighting is for nothing? What if? And the reason we can't do anything about the water vapor is.... the economy and convenience. What if that's the case?
