Ramesh Thakur, of the Australian National University, strongly puts the case that there is a parallel between the failed prophecies of doom by the climate change lobby, and the fear-mongering done by the cult of Covid to get people vaxxed, and continually vaxxed to the hilt. Thus, we have the climate changers alleging that there is only ten years to save the planet, but that 10 years never gets counted down, so it is always 10 years, and has been for decades. No climate apocalypse yet. Other times they are explicit about the date of doom; and once it is reached without the predicting coming true, yet another is made, along the lines of religious cults, as discussed in the classic study, by Leon Festinger (et al.), When Prophecy Fails (1956).
The same occurred with Covid, as even though only the immune suppressed and the aged were at great risk, otherwise healthy groups like children and teenagers were originally seen to be at equal risk; but that claim has now been dropped even by the World Health Organization. The pretty blue face masks were at the early days of the Covid years, regarded as inadequate then became mandated, and still are for healthcare settings.
