As NOAA launches a major upgrade of its flagship weather forecast model today, an important part is the Global Forecast System’s new dynamical core. The story of how scientists developed the dynamical core or engine for the model is a view into how scientific invention works.
A recent NOAA-led study found the speed of movement of tropical cyclones, including hurricanes, has been slowing in recent decades, with more storms lumbering slowly over land and potentially causing more flooding. However, new research published in Nature by another NOAA scientist casts some doubt that tropical cyclones are slowing and that there’s a link to climate change.
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.
The National Oceanic and Atmospheric Administration today announced it has selected Colorado State University in Fort Collins, Colorado, to host NOAA’s cooperative institute focused on developing new satellite products and models designed to improve weather and climate prediction.
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.
For scientists at NOAA, Earth Day — and every other day of the year — is about getting to the bottom of some of the most pressing questions about the planet we call home: how it works, how it’s changing, and how humans are affecting it.
