Real climate diplomacy is a negotiation over levers, not a single dial: carbon prices, coal phase-out dates and clean-energy investment across unevenly-developed blocs, all of which only matter through their effect on cumulative emissions. This simulator lets you set those levers for a Developed bloc, an Emerging bloc and the Rest of the World, then projects each bloc's annual emissions out to 2100 and converts the resulting cumulative CO₂ into a warming estimate using the Transient Climate Response to Cumulative Emissions — the same near-linear relationship the IPCC uses to define remaining carbon budgets. Watch the 3D emissions skyline bend as you raise a carbon price or move up a coal phase-out date, and see in real time whether your policy mix keeps cumulative emissions under the roughly 667 GtCO₂ left for a 1.5°C-aligned world.
