NOAA Research included in NOAA's Arctic report shows carbon once stored in the tundra's permafrost is actually being released into the atmosphere.

Source: NOAA’s Global Monitoring Laborator y The chart shows the increase in global carbon dioxide levels over the course of each year. In 2023, they grew by around 2.8 parts per million.

Carbon dioxide levels as measured atop a Hawaiian volcano extended their record-breaking rise in 2023, reaching a level more than 50% higher than at the onset of the industrial era, U.S ...

The Arctic is now a carbon source, instead of a carbon sink, according to a new report released by NOAA. Warming temperatures, melting permafrost and increased wildfires have contributed to the ...

NOAA maintains a global backbone of measurements of carbon dioxide and other gases, not just at Mauna Loa, but at more than 50 stations around the world. In parallel, our program at Scripps ...

The carbon dioxide (CO2) level measured in May in Hawaii averaged 424 parts per million, NOAA said. That’s 3 parts per million more than last year’s May average and 51% higher than ...
