Ancient Trees are Sensitive to Climate Anomalies

Caption

Ancient trees, such as Polylepis tarapacana growing in rocky soils in the South American Altiplano, are sensitive to climate anomalies associated with large-scale climate patterns stemming from the El Niño-Southern Oscillation. Reading the rings of thousands such trees lining the Pacific rim, Li and Xie found that recent El Niño activity is at its highest for the past 700 years, possibly a response to ongoing global warming.
