Hydroclimate of the northeastern United States is highly sensitive to solar forcing
[1] Dramatic hydrological fluctuations strongly impact human society, but the driving mechanisms for these changes are unclear. One suggested driver is solar variability, but supporting paleoclimate evidence is lacking. Therefore, long, continuous, high-resolution records from strategic locations ar...

[1] Dramatic hydrological fluctuations strongly impact human society, but the driving mechanisms for these changes are unclear.
