Frequently asked questions
How much has Iran warmed?
Averaged over the whole country, the last ten years (2016–2025) were 2.3 °C warmer than 1951–1980 according to Copernicus ERA5 — faster than the global average of 1.1 °C over the same period. Land areas warm faster than the oceans, so most countries warm faster than the global figure.
How much warmer will Iran be in 2050?
Climate models project Iran to be about 1.9 °C warmer in 2040–2059 than in 1995–2014 under an intermediate scenario (SSP2-4.5; model range 1.3–2.4 °C), and 2.5 °C under very high emissions (SSP5-8.5).
How much CO₂ does Iran emit?
Iran emitted 793 million tonnes of CO₂ from fossil fuels and industry in 2024, 2.1% of the global total, or 8.7 tonnes per person — 1.8 times the world average. Historically it has emitted 1.2% of all CO₂ since 1750.
