This statement alone renders the writer suspect. Water vapor is a more powerful greenhouse gas than CO2. That's why moist nights are warmer than dry ones. That's why desert temperatures can drop from the 100s to near freezing overnight. Persons not knowing something as basic as this have no business writing 'scientific' articles.
They have no intention of being scientific. They are out to influence the idiot vote. Morons suck this up like the author sucks up yellow snow.
