The atmospheric level of carbon dioxide has been steadily rising since the 1960's. In 2021, atmospheric carbon dioxide levels reached a high
of 416.45 parts per million, in comparison to 1960 levels which stood at about 316.91 parts per million. Carbon dioxide emissions largely come from human activities such as burning fossil fuels and deforestation, and are a primary driver of climate change. Historic average carbon dioxide (CO2) levels in the atmosphere worldwide from 1959 to 2021 (in parts per million)*

This table presents the most up-to-date, daily average reading for atmospheric CO2 on the planet. Units = parts per million (ppm).
What is the current concentration of CO2 in the atmosphere 2022?[+] Carbon dioxide measured at NOAA's Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 420.99 parts per million in May, an increase of 1.8 parts per million over 2021, pushing the atmosphere further into territory not seen for millions of years.
How much CO2 carbon dioxide is in the atmosphere today?Based on analysis from NOAA's Global Monitoring Lab, global average atmospheric carbon dioxide was 414.72 parts per million (“ppm” for short) in 2021, setting a new record high despite the continued economic drag from the COVID-19 pandemic.
