2023 saw record high levels of CO2 and methane, key greenhouse gases, in the atmosphere, with a 5.5% methane increase over the past decade, primarily due to human activities.
In 2023, record high levels of carbon dioxide and methane, key greenhouse gases, were reached in the atmosphere, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). Carbon dioxide rose by the third-highest amount in 65 years of record-keeping in 2023, while methane experienced a 5.5% increase over the past decade. Methane, a shorter-lived but more potent heat-trapping gas, is responsible for about 30% of the current rise in global temperature. Both gases are primarily caused by human activities.
