New research by NOAA and a visiting scientist from India shows that warming of the Indo-Pacific Ocean is altering rainfall patterns from the tropics to the United States, contributing to declines in rainfall on the United States west and east coasts.
An expedition to the central Arctic will give scientists the first opportunity to study the dramatic changes sweeping across the top of the world for an entire year.
An annual zooplankton surveys help scientists track the health of the Bering and Chukchi seas.
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 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.
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.
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.
New NOAA research demonstrates that drones and weather balloons can gather data needed to improve weather forecasts in severe working environments.
Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory averaged more than 410 parts per million in April and May, the highest monthly averages ever recorded.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
