High elevation shrubification in the subarctic during the Holocene Thermal Maximum and 21st century

Future changes in high latitude shrubification are expected to amplify warming. However, the elevational range and climate sensitivity of shrubification is poorly constrained, which hinders our ability to tune Earth system models. Using a sediment record from a high-elevation lake in Iceland (422 m asl), we leverage an...
