The International Tree-Ring Data Bank is a vital scientific resource containing over 6,000 tree ring chronologies used to study long-term climate patterns and environmental changes.
A new study finds wildfire smoke significantly raised fine particulate matter and ozone levels, leading to numerous days when air pollution exceeded health standards.
New international shipping regulations have drastically cut sulfur emissions from ships. While crucial for improving air quality and public health, reducing ship tracks also reduces their cooling effects.
A new study finds the observed increase in tropical cyclone frequency near Western Europe from 1966 to 2020 is likely linked to the anthropogenic aerosol effect.
2023 was a record-breaking year. According to the Annual 2023 Global Climate Report, 2023 was the warmest year since global atmospheric temperature records began in 1850, at 1.18°C (2.12°F) above the 20th-century average of 13.9°C (57.0°F).
Near-fire smoke is associated with lesser production of ozone, but aged wildfire smoke can increase levels of ozone in locations thousands of kilometers from the wildfire.
NOAA Ship Gordon Gunter journeyed away from Pascagoula, Mississippi for 90+ days and 12,700+ nautical miles to support of a key tropical Atlantic observing system.
Researchers from the Southern Climate Impacts Planning Program have published a case study of how Oklahoma military installations prepare for extreme weather.
A new study finds improvements in how models simulate surface wind responses to sea surface temperature changes are key to enhancing prediction skill.
New projects will improve understanding of atmospheric methane budgets to inform successful policies for reducing greenhouse gas emissions, address major sources of uncertainty in methane measurements and modeling, and reduce community-level methane emissions.
