Even if CO2 were the primary GHG, the main source of pollution would be bunker oil used in China, especially shipping, yet that source of GHGs was excluded from the Paris accords. Why does the left always target the US right wing as the main source of CC obstructionism, while they ignore, and put in policies that allow China to continue on this path. It's 100% political, it's a disgrace.
It's time to implement major environmental tariffs on these countries, you kill two birds with one stone here, stopping their emissions, and correcting trade imbalances. I have spoken to Republican leadership about this as the next logical step in the trade war.
He is right that H2O is the primary GHG, there's just not a lot we can do about it.
In fact one of the (several) problems with using hydrogen as jet fuel is the fact that the combustion byproduct is almost 100% water... and dumping a bunch of that into the stratosphere is still a problem, because it's not supposed to be there. So hydrogen can be totally carbon-neutral but is still a greenhouse problem (for jets, not really at all for low-altitude vehicles since water normally resides in the lower atmosphere, and any excess just precipitates as per temp/humidity conditions). Hydrogen would still actually produce less water than kerosene, which has a bunch of H to unload via bonding with O2 to make water.
