Everyone is so sensational about climate change but never looks at Earth's history.

Were at the tail end of an ice age.

For most of Earth's history, there were no polar ice caps.

For 400 out of 500 million years the earth was warmer than it is now.

The earth is 4.5 billion years old so I don't understand what you mean with "400 out of 500 million years".

Also for a lot of that time earth was a hellishly hot place with little life.

The past 500 million years have been rich with life.

That's disingenuous misdirection. The current change is a threat to humanity of our own making.

> threat to humanity of our own making.

How? Do you have concrete examples or just fear based conjecture?
