Tree Ring Grant Will Allow Look at Past Temperatures in Eastern U.S.

March 09, 2020

U of I geographer Grant Harley and colleagues will be using tree rings to reconstruct summer air temperature in the Eastern United States, from North Carolina to maritime Eastern Canada. Past research has documented temperatures over the last roughly 120 years, and with the help of a $360,000 National Science Foundation grant, this new work will look back over the past 300-500 years of temperatures. This new study will help scientists understand temperature trends across the Northern Hemisphere and predict future climates.
