USGS contributes to the Fourth National Climate Assessment
USGS Research Hydrologist Glenn Hodgkins co-authored the Fourth National Climate Assessment’s Northeast chapter. USGS Research Geologist Erika Lentz was also a co-author. The recently published chapter discusses historical and potential future impacts of climatic changes on New England’s people and natural resources, including it’s inland and coastal waters.
The chapter is available at: https://nca2018.globalchange.gov/downloads/NCA4_Ch18_Northeast_Full.pdf
A figure in the Northeast chapter is based on research led by USGS Hydrologist Robert Dudley. It shows changes during the last half century in the timing of winter-spring snowmelt related runoff.

Trends in snowmelt-related streamflow timing in the conterminous United States
Changes in snowmelt-related streamflow timing have implications for water availability and use as well as ecologically relevant shifts in streamflow. Historical trends in snowmelt-related streamflow timing (winter-spring center volume date, WSCVD) were computed for minimally disturbed river basins in the conterminous United States. WSCVD was...
