The 2015 Paris Agreement establishes a specific goal: to hold the increase in the global average temperature to well below 2°C above pre-industrial levels. This policy approach focuses on preventing a specific, potentially catastrophic environmental outcome, even though the precise economic costs of achieving this goal are uncertain and may be very high. Which of the following best explains the economic rationale for setting such a firm, science-based limit?

Evaluating the Paris Agreement's Policy Framework

The primary justification for the 2°C temperature limit in the Paris Agreement is a detailed economic calculation showing that the monetary benefits of staying below this threshold precisely outweigh the costs of the required climate actions.

Analyzing Policy Logic for Global Threats

Match each feature of the 2015 Paris Agreement with the corresponding principle of a policy designed to manage outcomes under deep uncertainty.

In the context of policies designed to manage outcomes under deep uncertainty, the 2015 Paris Agreement's specific goal to limit global temperature rise to well below 2°C above pre-industrial levels acts as a __________, a pre-determined threshold established to prevent a potentially catastrophic environmental outcome.

A group of international policymakers is tasked with addressing a complex global threat characterized by deep uncertainty and the potential for a catastrophic, irreversible outcome. Based on a policy approach that prioritizes avoiding this disaster above all else, arrange the following steps in the most logical order they would take.
