As anybody who has actually looked at the science knows, the contrived phenomenon called anthropogenic global warming or anthropogenic climate change is purportedly driven by CO2. Because additions to atmospheric CO2 alone have such a mega tiny influence on temperature, the advocates of the fantasy surmised that those additions cause atmospheric water vapour to be increased and that amplifies the CO2 "warming". There are a myriad of reasons why this fantasy based on fantasy is plain nonsense but the real killer is the climate. CO2 volumes are at their highest for millions of years, well, at least since 1940. Water vapour levels are falling.
