A sooty cloud generated by a 2017 firestorm provided an ideal opportunity for researchers to test a climate model that simulated the lifetime of that soot in the stratosphere.
A new NOAA and University of Michigan study using an instrumented airplane has found unexpectedly large emissions over five major cities along the East Coast - twice the total amount of methane and almost 10 times the amount estimated from natural gas.
A new NOAA study in the Journal of Climate warns that in the already warm and frequently dry southern Great Plains and Southwest, climate change will make compound heat-wave and drought events significantly hotter than they used to be.
The results of a new NOAA study snowing a strong response by the North American biosphere to El Ninos highlight the importance of improving understanding of regional carbon-climate relationships, which represent a major uncertainty in future climate projections.
Carbon dioxide levels reached the highest seasonal peak recorded in 61 years of observations at NOAA's Mauna Loa observatory. This the seventh consecutive year of steep global increases in concentrations of this important greenhouse gas pollutant.
The 2017 Northern Plains drought hit hard and without warning, desiccating pastures, rangelands and wheat, sparking massive wildfires, and causing widespread livestock sell-offs across the Dakotas, northeastern Montana and the Canadian Prairies. While it wasn't the region's worst drought, it caused $2.6 billion in losses. A new study shows droughts like this are 20% more likely due to climate change.
Record levels of greenhouse gas pollution continued to increase humanity’s impact on the atmosphere’s heat-trapping capacity during 2018, according to a yearly analysis released by NOAA scientists today.
Despite a 46 percent increase in US natural gas production since 2006, there has been no significant increase of total US methane emissions, and only a modest increase from oil and gas activity, according to a new NOAA analysis of long-term atmospheric measurements.
Findings could help improve air quality in cities across the U.S. West.
"Coupling" two NOAA research models improved the accuracy of lake-effect snow forecasts during a recent experiment.
