What is generally not understood is that our current icehouse phase is rare.

'A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet... Earth has been in a greenhouse state for about 85% of its history.

'Earth is now in an icehouse state, and ice sheets are present in both poles simultaneously... Earth's current icehouse state is known as the Quaternary Ice Age and began approximately 2.58 million years ago.'

Modern humans have existed for 60k years, all of which have been in this current icehouse.

To cast a different shade on the meaning, this climate period is rare, easily disturbed, and difficult to restore even with vastly more powerful technology. The more common greenhouse state is unlikely to lead to a Venus runaway, but it will be hostile to us.

We might very well require the rare climate, and perish in the common.

Previous climate changes happened over tens of thousands of years. This one is happening in decades.

It's the speed, not the magnitude that matters. Change faster than evolution and migration will destroy ecosystems.

Finally a human with a context window larger than a few hundred years.

Difficult is good. It makes it more competitive. It levels up the game.
