Aerial view of recent lava flows near Mauna Loa’s summit in November 2022. The National Oceanic and Atmospheric Administration (NOAA) monitors greenhouse gases at Mauna Loa Observatory, which is 4 miles (6 kilometers) away from the summit crater. Despite the proximity, volcanic gases aren’t common at the observatory, and when they do happen, these temporary spikes are not included in the long-term data. The decades-long trend of increasing CO2 at Mauna Loa matches that from sampling sites all around the world. Credit: USGS/J. Schmith
