🔭 Scenarios
Move the levers and see where the world ends up by 2100: how many people, how much each of them produces, how much energy and CO₂ that costs, how much forest is left — and how warm it gets.
How much CO₂ the world emits each year: what the five indicators below multiply out to, plus what forests give back or take away.
How much CO₂ there is in the air, in parts per million. It was 280 before the industrial revolution.
How much warmer the world gets, to 2100. It follows the five below — people, output per person, energy per dollar, CO₂ per kilowatt-hour, and forests — through the emissions they add up to.
All the CO₂ ever emitted, adding up. It is what sets the concentration, and through it the temperature.

How much CO₂ each kilowatt-hour costs, to 2100. It falls as coal, gas and oil give way to the rest.
Share of land covered by forest, to 2100. Forests take CO₂ out of the air: losing them adds emissions, planting them removes some.
World population to 2100.
GDP per capita to 2100: how much each person produces.
How much energy each dollar of output needs, to 2100. It falls as economies get more efficient.
