Climate, CO₂ and emissions

50,411 country-year rows and 79 columns covering CO₂ emissions by source (coal, oil, gas, cement, flaring), per-capita and per-GDP intensities, consumption-based emissions, cumulative totals, shares of global emissions, methane, nitrous oxide and total greenhouse gases, plus population and GDP, from Our World in Data's CO₂ dataset as of 2026-09-05.

1,759 monthly global land-ocean temperature anomalies (°C relative to the 1951–1980 mean) from NASA GISS Surface Temperature Analysis v4, January 1880 to 2026-09-05.

821 monthly mean atmospheric CO₂ concentrations (ppm) at Mauna Loa Observatory from March 1958 to 2026-07, with the deseasonalised trend value, the number of daily means in the month, their standard deviation and the uncertainty of the monthly mean, the 1958–1974 months from Scripps Institution of Oceanography and the rest from NOAA, from NOAA Global Monitoring Laboratory as of 2026-09-06.

15,975 daily mean atmospheric CO₂ concentrations (ppm, dry-air mole fraction) measured at Mauna Loa Observatory, Hawaii, from 1974-05-19 to 2026-09-03, with the decimal year of each observation; days without a quality-controlled mean are absent and the December 2022 to July 2023 values come from Maunakea while the 2022 eruption cut off Mauna Loa; from NOAA Global Monitoring Laboratory as of 2026-09-06.
