The present is often different from the past. Change happens. There has been non-anthropogenic climate change in the past. It does not follow that there is no anthropogenic climate change now.
I had the flu once. It does not follow that I can't get cancer. Yesterday was Saturday. It does not follow that today can't be Sunday.

Yes, humans are putting billions of tons of carbon in the atmosphere. That is
one factor. But there is no way of proving it's the causative reason. You could only prove that if you could account for all other factors from your calculation, over time. but no one can accurately describe all the non-anthropogenic factors to start with. So to say any correlative facts are causitive is simple not proven.
For example, there have been a lot of sunspots (on average) in the 20th century. The Maundy Minimum saw sunspot drop to around 1 per every 10 years! And with that drop occurred the Little Ice Age in the 1600's. Can I prove causation? Of course not, too few data points. But the 20th century temperature run up could be caused by either, both, or neither. Too little data, too sparse.
As to the Ice Ages themselves, we don't have a clue why they started or stopped. We just know they did. Maybe we are in a warm bubble before the next Little Ice Age. After all, there's been 4 bubbles like this before. Who knows, not enough data! Maybe all that carbon is staving off the next Ice Age...
Having said all this, I can't see the implementation of Draconian standards, reducing the standard of living for (literally) billions of people, over something
not proven. Especially when technology will probably be solving the problem within the next 50 years anyway.
But all this doesn't matter to Global Warming Believers. They
know the Truth, and want to convert everybody to their beliefs, no matter how much it may hurt the convertees....
