Question 1: Present vs. Future

Suppose that the government of a flood-prone region has allocated a certain amount of money for disaster prevention. It can invest either in short-term measures, which will save 100 people from drowning this year, or in long-term mitigation, which will prevent 200 people from drowning 50 years from now.

In your opinion, which option should the government choose?


Save 100 lives now

Save 200 lives in 50 years

Question 1: Present vs. Future (continued)

Suppose now that future climate impacts will be worse than expected, so long-term mitigation cannot save as many lives as previously thought. The government can save 100 people from drowning this year, or save 150 people from drowning 50 years from now.

In your opinion, which option should the government choose?


Save 100 lives now

Save 150 lives in 50 years

Question 1: Present vs. Future (continued)

Suppose that future climate impacts will again be worse than expected, so long-term mitigation cannot save as many lives as previously thought. The government can save 100 people from drowning this year, or save 115 people from drowning 50 years from now.

In your opinion, which option should the government choose?


Save 100 lives now

Save 115 lives in 50 years

Question 1: Present vs. Future (continued)

Suppose now that short-term conditions will be worse than expected, so the government cannot save as many lives as previously thought. It can save 80 people from drowning this year, or save 200 people from drowning 50 years from now

In your opinion, which option should the government choose?


Save 80 lives now

Save 200 lives in 50 years

Question 2: Inequality

There has been a catastrophic drought in a rural area, and two farmers have lost their entire livelihood. A relief agency has arrived to help restore the farmers' land. However, its budget is limited, and one farm is harder to rehabilitate than the other due to the landscape.

Therefore, the agency is considering two different options: it can spend the same amount of money on both farms, which will result in more rehabilitated land for farmer 1; or it can restore the same amount of land for both farmers, which will result in less restored land overall.

Which option would you choose?


Farmer 1: 80 acres restored
Farmer 2: 20 acres restored
(Total: 100 acres)

Farmer 1: 40 acres restored
Farmer 2: 40 acres restored
(Total: 80 acres)

Question 2: Inequality (continued)

Suppose it turns out that Farmer 2's land is more difficult to restore than previously thought, so it is more expensive to give both farmers the same amount of land. The agency is now considering the following two options.

Which option would you choose?


Farmer 1: 80 acres restored
Farmer 2: 20 acres restored
(Total: 100 acres)

Farmer 1: 35 acres restored
Farmer 2: 35 acres restored
(Total: 70 acres)

Question 2: Inequality (continued)

Suppose it turns out that Farmer 2's land is again more difficult to restore than previously thought, so it is more expensive to give both farmers the same amount of land. The agency is now considering the following two options.

Which option would you choose?


Farmer 1: 80 acres restored
Farmer 2: 20 acres restored
(Total: 100 acres)

Farmer 1: 30 acres restored
Farmer 2: 30 acres restored
(Total: 60 acres)

Question 2: Inequality (continued)

Suppose it turns out that Farmer 2's land is less difficult to restore than previously thought, so it is less expensive to give both farmers the same amount of land. The agency is now considering the following two options.

Which option would you choose?


Farmer 1: 80 acres restored
Farmer 2: 20 acres restored
(Total: 100 acres)

Farmer 1: 45 acres restored
Farmer 2: 45 acres restored
(Total: 90 acres)

Climate policy simulator

How we respond to the challenge of climate change depends both on scientific assessments of the impacts of climate change and on value judgments.

On this website you can learn more about scientific assessments, value judgments, and how they interact in our simulator, which is representative of leading policy models.

The value judgments are your call! We will ask you a few questions to elicit your own value judgments.

Afterwards, we will show scenarios that implement the best policy according to your value judgments. Several scenarios are possible, depending on assumptions that can be made about how big the climate impacts will be, and how they will affect different populations.

Along the way, you will be offered explanations about how the construction of such scenarios is made. You can also find a repository of all the explanations by clicking on "Learn more" on the left of the screen.
