Climate change over millions of years is indeed natural. A total shift in the entire planet's environment over a couple of decades due to humanity is not natural.
Honestly, I view people who don't accept climate change as equal to the people who believe the Earth is flat.
Yes there is "natural" climate change, that humanity has absolutely nothing to do with.
But that is small potatoes compared to the "holy bajeezus" level of climate change that has happened since the industrial revolution...
An amazing analogy that I've heard goes as follows.
Let's say you have an aquarium with exactly 100 liters of water. Now, the water needs to be recycled, so it takes out 10 liters of water out of the tank every hour. To compensate, it also adds 10 liters at the same time. The water stays at the same level because the same amount that leaves also enters. Let's say I make a very small change. It will keep removing 10 liters of water every hour, but it will instead add 11 liters of water every hour. It's a really small amount. A measly 1% more water total per hour.
And that 1% more is massive. During the first hour it won't matter. In 12 hours? That's a lot more. That small increase is starting to get pretty close to the top of the water. The amount of greenhouse gasses that we are adding isn't massive. But it is accumulating. Eventually, the tank is going to overflow.
It's a similar, rational argument
