Sooner, rather than later. People have no idea what's coming.

They think they do, but they don't.

The planet is making a "state change" to adjust to a new climate energy state. The Climate System is now permanently (barring massive geoengineering or 30% population died back by 2030) at a +1C energy level now.

The last time this was true, was the period between 3-5 million years ago. None of us have any idea what's coming.
