Nope, you have to read graphs carefully. Those lines took at least
some thousands of years. Our only took a century or two, and will go
much higher in another one.

Notice that each of the three "tiny changes" you listed is an ice age.
It means that, even if the change doesn't make itself obious in the
600 million year graph, it doesn't mean that it has no consequences.
And the speed is what matters. But if you think an ice age is a tiny
change, I don't think we can arrive at any agreement.
