New Study Traces Indigenous Population Shifts in North America Before Europeans
DRI’s Erick Robinson, Associate Research Professor of Climate and Archaeology, co-authored a new study that provides insight into North America’s Indigenous communities prior to European contact. The research found that although Indigenous populations varied regionally, the continent saw a population peak around 1150 A.D. before experiencing declines, likely stemming from drought, disease, emigration and warfare. A brief recovery around 1500 A.D. was followed by a sharp decrease upon the arrival of Europeans.
Floods, Droughts, Then Fires: Hydroclimate Whiplash is Speeding up Globally
DRI’s Christine Albano co-authored a new study that examines how a warming climate is creating an atmosphere more prone to extreme weather. This “hydroclimate whiplash” is evident in California’s recent weather, with winters filled with repeated atmospheric river storms driving the plant growth that the dry summers then parched, providing plentiful fuel for explosive wildfires.
