No Tricks Zone: New Scientific Evidence Robustly Affirms Scandinavian Temperatures Were 3-4°C Warmer 9000 Years Ago

Because trees may only grow within narrowly-defined temperature ranges and elevations above sea level, perhaps the most reliable means of assessing the air temperatures of past climates is to collect ancient treeline evidence.  In a new paper, Kullman (2018) found tree remnants at mountain sites 600 to 700 meters higher than where the modern treeline
