What it proves

Climate change is a macroeconomic issue, not only environmental.

How to deploy: Use World Bank estimates combined climate risks, environmental degradation and air pollution could reduce GDP by at least 18 (World Bank estimates combined climate risks, environmental degradation and air pollution could reduce GDP by at least 18-20% by 2050 without action., to 2050) to support the claim that Climate change is a macroeconomic issue, not only environmental.

Draft — not reviewed

What it does not prove: The 18-20% is a no-action scenario bundling three distinct drivers — climate risk, environmental degradation and air pollution — so it cannot be cited as the cost of climate change alone, and it is not comparable to the narrower up-to-9% climate-only estimate in E467. It is a projected deviation from a counterfactual path to 2050, not a forecast that GDP will be 18-20% lower than today.

Memory hook: 18-20% of GDP by 2050 → climate plus dirty air plus degraded land, combined

Rebuts the claim: "Environmental protection is a luxury Pakistan can defer until it is richer" — the cost of deferral is a fifth of the 2050 economy.
