The point about water vapor is an important one, especially about CO2 being a trace gas, essential to life on Earth.
The power of the oceans to cleanse more carbon out of the atmosphere per year than we can imagine, that the oceans heat sink capacity runs on a three century timescale...
And taking away the opportunity for growth among the poor. That's an essential point. No green energy, as they call these fantasies, gets the world past about 2050.
But the truth doesn't matter to ideologues like Zero. What a monster.
Water vapor is very important. The entire CO2 farce requires a positive feedback of water vapor. The minuscule amount of higher CO2 causes more water vapor. That water vapor is the control factor for significant warming. So the climate change crowd are promoting less water vapor and greater droughts. In essence.
