There is no 'prevention of climate change' . This stuff is about taxing, raising prices, and big government funding for 'green technologies' like battery powered cars and also funding alot of bogus 'climate research' such as massive supercomputers that 'model' the climate. It's called the climate industrial complex and it's worth trillions; And it was also just after 1988 when the Big Gov $$ started going into this agenda.
You also have to consider that the 'line' or 'talking point' you get from the IPCC, NOAA, NASA.Goddard ICAP, whatever isn't just that there's 'global warming' as there was clearly global warming prior to the industrial revolution; It's that there is this 'extreme' amount of global warming-like because CO2 levels have exceeded 400ppm it's going to turn this planet back into what it was during dinosaur times (when the CO2 was 4000ppm). After 150+ years of industrial revolution and 'runaway greenhouse effect' that is clearly not happening, but by now this thing is too big to fail. Can you imagine if one day the big globalist government just said "whoops sorry, the runaway greenhouse effect isn't happening so we're zeroing out the whole climate thing" It would be tantamount to the US Defense Department deciding to cut nearly it's entire budget because actually they're not defending the US, they're defending their various enterprises around the world-and they're just not going to do that anymore, those other countries can defend themselves.
