One graph of data that shows the increased rate of warming over the last 150 years begins 2,000 years ago. Not the 4 1/2 million years that has your attention but hardly cherry picking.

OK, so which is it? Our increased warming began 150 years ago with the industrial revolution, or 2,000 years ago????? You're contradicting yourself.
But don't worry, your nieces and their children won't have to deal with it, not unless they live to be 25,000 years old.
The 4 1/2 million year date is the beginning or our
current ice age. There have been numerous ice ages prior to this. And during this time, there are 70-120,000 year cycles of glaciation and interglacial thaws driven by the power of the sun, Earth's orbit and changes in Earth's axis, among other things. Currently we are 20,000 years into a warming cycle. None of it has anything to do with fossil fuels. This is why the 4 1/2 million years mark is relevant--it explains where our climate came from and why we are here today.
Are we accelerating the warming??? Maybe, but there isn't enough data nor any conclusive proof. Are the alarmists correct? Maybe, only time will tell. But that time frame is measured in millennia, not the lifetime of your grand-nieces.
