Yes, the whole thing is nothing but a gigantic hoax. In the same way that the western world was convinced Jesus Christ died for "our" sins and rose from the dead some two thousand years ago, they are now convinced that mankind has doomed the earth to a fiery end because of carbon emissions.
Both doctrines, or dogma, if you prefer, require one essential ingredient to persist. That ingredient is faith.
Faith allows one to believe in anything one chooses to believe in. Faith doesn't require truth or evidence. Faith ignores cognitive dissonance.
Climate is now a religion. It has replaced God as Nietzsche foretold. The priests, pastors, vicars and oracles of Christianity have been replaced by climate pundits such as Greta et al. The money that once flowed to the various religious organisations now flows to the WEF, WHO, and any other number of organisations that support and advocate the doctrine. They are all of-course corrupt, as were the Churches.
Climate has replaced God in the hearts of the minions. Mankind need something to believe in, something to give them hope for the future. It really doesn't matter how outrageous their beliefs are - JC rising from the dead and offers us an eternal life in heaven, (or an eternity in Hell - go figure), or a gas that is 0.04% of the atmosphere will determine our heaven or hell on earth.
You can't argue using truth, logic, and undeniable empirical evidence against a person of faith. Regardless of everything else, they will drink the Kool Aid.
And while the "idea" of a God is, morally speaking, a reasonable MO to conduct one's life, fanatical belief in any form of God doesn't usually bode well. I compare the current fanaticism of the climate warriors with that of the Inquisition - faith, fanaticism, narcissism, all rolled into one.
It' not until one's "faith" has a severe hole punched into it that questions will be asked. This will happen when climate policies result in blackouts and famine, the inability to travel, or God forbid, a severe shortage of smartphones and a reversion to dial-up due to insufficient electrickery to power the cell sites.
