OperationId:environment_co2_temperature_contribution_iso3

Returns the per-country contribution to observed global warming, decomposed by gas (CO2, methane, nitrous oxide, total greenhouse gases) and expressed in degrees Celsius. Includes the share-of-total percent. These values are CONTRIBUTIONS to warming, not absolute temperatures. Methodology from Jones et al. National contributions to climate change (2025); redistributed by Our World in Data. Published under CC BY 4.0 with dual attribution.
