Hydropower plants are important sources of renewable energy, but the climatic impacts of
their constructions remain poorly explored. Considering that tree growth analysis is a useful
tool to identify environmental impacts, this study aimed at using climate records and tree-ring
chronologies to understand possible local climate changes caused by the construction of a
hydropower plant in the 1980s in the State of Paraná, Southern Brazil. Historical climatic
data were obtained from the local meteorological station and surrounding municipalities and …
