Analysis
Iran recorded 0.0158 °C for contribution to global mean surface temperature rise from fossil sources in 2024. That is the highest value across all 174 years on record.
That represents a change of up 2.9% on the previous year and up 34.4% over ten years.
Over the whole period, contribution to global mean surface temperature rise from fossil sources in Iran peaked at 0.0158 °C in 2024 and was at its lowest, 0 °C, in 1851.
That places Iran 12th out of 214 countries with data for 2024, putting it in the top 10%.
The series is highly variable year to year, so single readings are best treated with caution.
