First step: assigning roles. Decision-makers in developed, developing, and underdeveloped countries.
Second step: Each country group works independently on the following. They have to make decisions about commitments to stop the production of greenhouse gases and the time they will reach the equilibrium point of CO2.
Third step: All types and countries meet and report their decisions. The tool calculates how much the temperature will rise from these decisions. The challenge is that the temperature does not rise more than 2 degrees centigrade by 2100.
Finally, this result serves to observe how much coastal cities would be affected by these global decisions.
And based on this result, the impacts on public health are identified.
