Current Ppm Of Co2 In Atmosphere 2025 Current. Atmospheric CO2 Jump in 2024 off Track With Trajectory Needed to Meet 1 Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO 2 itself, after water vapor has been removed Long-term trends in CO₂ concentrations can be measured at high-resolution using preserved air samples from ice cores.

Units: parts per million (ppm) This table presents the latest, daily average reading for atmospheric CO2 on the planet So a 0-24 hour UTC day runs from 2PM the previous day to 2PM. Monthly Averages & Trends of Atmospheric CO2 Between 1979-2024
Carbon Dioxide Passes 400 PPM Milestone, NOAA Finds Climate Central. Trends in Atmospheric Carbon Dioxide (CO 2) Mauna Loa, Hawaii; Global; CO 2 Animation; CO 2 Emissions; Last Month; Last 1 Year; Full Record; Between 1979-2024, the concentration of carbon dioxide (CO2) in Earth's atmosphere has increased from an average of 336.56 PPM to 425.19 PPM (parts per million), a 26.33% increase during a 45 year time span.
Global carbon dioxide growth in 2018 reached 4th highest on record. Long-term trends in CO₂ concentrations can be measured at high-resolution using preserved air samples from ice cores. It contributes about 66% of the warming influence of all human-emitted GHGs—more than twice that of all others combined
