The question is; Do you want to burn, or freeze?
Here's what I know:
There a thing called the Milankovitch cycle, it has to do with the changes in earths orbit over time, and is why we have an ice age every 100,000 yrs or so, with a 20,000 yr inter-glacial period. It is a well understood and documented thing. One of the best evidences for mankind's contribution to climate change is that we have deviated from that natural cycle. According to some, we should be at the peak temperature of the cycle, or even on the downward side heading toward the next ice age, but instead we continue to warm at an accelerated rate.
So according to the "climate crisis" alarmists, if we do not fundamentally transform human society in 12 years we will all die from warming. BUT... if we somehow do all they demand, and eliminate all human effect on the climate, well, then it will revert to the natural cycle and we will all die from freezing.
So, you want to burn or freeze? The only certainty is that the climate will not remain static, simply because we wish it to.
Other questions:
Is climate change real? Of course, it is in constant change.
Is mankind to blame? Partially, evidence suggests we have caused a deviation from the natural cycle.
Is it an existential threat to us as a species? No, it is a very slow change. We will adapt using ingenuity and technology, just like we always have.
If it is an existential threat, is governments and regulation the solution? No.
In short, climate change is real, man contributes to it in some degree (how much is impossible to tell), and I don't worry about it at all. The people out there preaching it will be the end of our species either; (A) need some cause to give their live meaning, and this is it. or (B) stand to profit massively from the solutions they are hocking. or (C) politicians looking to get votes from groups A and B.
