I am of the opinion that the government (all governments) require a fearful population who look to their leaders for safety and salvation. In the old days (up until perhaps 100 years ago) we had good old religion to keep the congregation frightened and compliant. Now that religion has been sidelined we need other things to be scared of.
Climate change is the new religion, requiring faith, and needing tithes, sacrifices and obedience.
Covid serves a similar purpose, with all its arbitrary, ever - changing rules, requirements and beliefs.
Is the climate changing? Of course - it's what climates do. Is it all the fault of humans? Probably not, given that the climate changed for billions of years before humans existed, and will continue to change for billions of years after we have gone. Is there a small portion of change that might be attributed to humans? Perhaps. Maybe. The IPCC says (I think - it's hard to tell) that human are responsible for 5% of annual CO2 planetary output. If you removed all the humans from the planet, you might be able to make a small change to the climate...or you might not. Hard to say.
As to outright lies by climate scientists - remember "Climategate"?
Here's an alternative view of the current hockey stick graph and the underlying data that makes it so scarey:

Roger will be along shortly to tell us that this is a heretic site run by unbelievers, and must be expunged from the record immediately. No different to any other religion.
As a farmer, it is far more important for me to work out what is actually going to happen, as opposed to what the "experts" claim is going to happen. For the moment I think globally we
might be in for a bout of cooling which will cause me far more problems than a trivial bit of warming. Look to the southern hemisphere winter weather for a hint of what we will be getting this winter - it's not looking good so far, but one winter doesn't make a climate trend. I'll be proven right or wrong by 2030, hopefully.
