Simulate future global warming with Future Climate, an accessible, multi-layered climate model.

Starting with the world today, calculate global-averaged temperatures and radiative forcing based on your choices. Three modes allow for a customized learning experience:

  • Simple mode allows you to change all pollutants (carbon dioxide, methane and aerosols) at once.
  • Sector mode lets you change each economic sector separately: electricity, transportation, industry, agriculture and buildings.
  • Gas mode allows you to change carbon dioxide, methane, nitrous oxide and aerosols individually.

Decreasing all emissions at once will cause temperatures to spike at first, due to the removal of aerosols, which block out the sun. Over the next few decades, methane decreases, and temperatures go back to where they were before the emission change. Carbon dioxide lasts an extremely long time in the atmosphere, so temperatures stabilize at around that same value.

The app simulates three different possible future in each mode: one with a high climate sensitivity and large negative aerosol forcing (the dark red line), the middle range (red, number displayed as well), and a low climate sensitivity and low aerosol forcing case (yellow).

This model is a simplified version of the FaIR v1.3 climate model.
