We’ve been promised apocalypse by now several decades ago, and literally nothing changed.
CO2 is just a misdirection away from actually dangerous things such is persistent chemical pollutants we dump into the ocean by millions of tons that cause widespread hormonal disruption or outright toxicity.
that is happening today, not at some unspecified point in the future. So weird nobody seems to be concerned about that.
I personally find fans made very little difference for me in humid climates.
