With a background in climate and economics, NOAA's Chief Scientist is passionate about using knowledge from both worlds to strengthen the nation's resilience to climate variability and change.

The primary source of sulfur dioxide has historically been fossil fuel combustion and industrial activities, but wildfires are expected to occur more frequently and with longer durations due to land use changes and climate change. A new study examines how much sulfur dioxide is emitted by wildfires.

Methane emissions have shown unprecedented growth rates since 2020. These emissions can be thermogenic (from fossil fuel extraction and combustion) and biogenic (from plants and animals). A new study compares results from laser-based analyzers in identifying emission sources.

A new study incorporates observations from moorings installed along the Oregon coast in the 1990s and 2000s. The study incorporates the mooring measurements into a data set spanning more than two decades, and makes the data publicly available for the first time.

The newly released guide is the second in a series of guides to help community leaders use nature-based solutions (NBS) to minimize the risks of natural hazards.

Our blogger explains how scientists grade seasonal outlooks and talks about how this winter's outlooks for U.S. temperature and precipitation performed.

A converted Cold War bomber packed with sensitive instruments is investigating atmospheric chemistry and aerosols over the Arctic. The mission is part of NOAA’s growing Earth’s Radiation Budget research program.

A new NOAA analysis shows US emissions of the super-potent greenhouse gas sulfur hexafluoride have declined over 2007-2018, likely due to successful mitigation efforts by the Environmental Protection Agency (EPA) and the electric power industry.

NOAA’s Pacific Marine Environmental Laboratory has released “The Ocean: Earth’s Carbon Dioxide Sponge,” the latest video in the PMEL at Work short video series.

While much is understood about greenhouse gas contributions to surface warming, less is understood about impacts on ocean circulation. A new study uses a climate model to quantify the role of changes to the wind-driven ocean circulation onto global air temperature warming.
