Levels of the three most important human-caused greenhouse gases – carbon dioxide (CO2), methane and nitrous oxide – continued their steady climb during 2023, according to NOAA scientists.

A team of scientists from across NOAA have created a new tool to help people adapt to ocean acidification in a time of industrialization and increased emissions. The new data product, featured in the Journal of Advances in Modeling Earth Systems (JAMES), combines observational data with computer simulations and will provide improved global and regional projections for ocean change.

2022 was a busy year for volcanic eruptions with Hawaii's Mauna Loa and Kilaeau erupting simultaneously, along with Mount Semeru, Indonesia and the Hunga undersea volcano in Tonga. While the United States Geological Survey is the primary agency that monitors volcanic activity in the United States, the National Oceanic and Atmospheric Administration (NOAA) oversees safety systems for tsunamis and other volcano-related threats, as well as studies the impact of volcanic gasses on our global climate.

New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil turned what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.

In May, NOAA's measurements at the Mauna Loa observatory averaged 419.13 parts per million. Scientists at Scripps calculated a monthly average of 418.92 ppm. It's the highest level since accurate measurements began 63 years ago.
