Water moves through the hydrologic cycle, one of the most basic and vital processes of Earth’s systems, in three forms — as a liquid in seas and streams; as […]
As the Arctic Ocean begins to freeze for the winter, NOAA and University of Washington scientists gain insight from the air
Today, NCDC announced the launch of a new website that could help climate scientists estimate the historical intensities of hurricanes around the world faster than before—and the public is invited to help.
