A new climate history of the Pantepui region of southeastern Venezuela and southwestern Guyana demonstrates methods for tracking past climate change in tropical regions. The authors also use their reconstruction to track changes in the biosphere, hypothesizing that the region’s unique biota was preserved through these changes by migrating into lowland areas that today would not support them. The authors also address the difficulties of working in tropical areas where climate proxies usually lack sufficient resolution to create detailed records. Find more about the piece here.
