Now is the time to cool the Earth.

Run a limited budget and a limited staff. Build research facilities, recruit scientists, and develop the green technologies that do not exist yet. The future of humanity is in your hands.

2030

You begin on an Earth that is already too late.

At last the world faced the truth it could no longer put off. The nations surrendered their mitigation authority and their budgets to a single body — the International Environment Organization, UNEO. You are its Secretary-General.

Build

Build what is needed, gather the people, and find a way. A single power plant shifts the fuel mix of the entire world.

Research

Discover the technologies we do not yet know. Knowledge is what carries over to the next Earth.

Policy

Move the people of the world to act. There are only five slots — the question is always what you drop.

UNEO Charter, Article 1

There is hope, if the average temperature can be held at 14.5°C for 180 days or more.
And above all, do not cross 16.7°C.

You must draw it down 1.5°C to reach the target — yet the tipping point is only 0.7°C away.
