“The knowledge gained from this research will inform decision makers and stakeholders regarding potential future approaches to marine carbon dioxide removal in our oceans and lakes. We will need many mitigation tools to build a climate-ready future.”
The summer of 2021 was a smoky one for Denver and northeastern Colorado. Smoky haze from wildfires in Arizona, California, and the Pacific Northwest shrouded …

The Annual Greenhouse Gas Index is a measure of the climate-warming influence of long-lived trace greenhouse gases in the atmosphere and how that influence has changed since the onset of the industrial revolution.
Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.
Major hurricanes, intense wildfires, increasing concentrations of greenhouse gasses, deep sea discoveries, and more made 2022 an eventful year for NOAA Research. As we enter the final days of the year, we’re taking a look back at some of our biggest accomplishments from the last 12 months.
