1783-1784 Laki Eruption and Alaska

This project was the result of my master’s research into the northwestern North American climate response to the 1783-1784 CE Laki eruption. We used a combination of quantitative wood anatomy, proxy systems modeling, and climate model simulations of the Icelandic eruption to show late-summer cooling in Alaska following the eruption. This study both demonstrates the importance of timing and internal variability when comparing proxy temperature reconstructions and climate model simulations, and the value of developing cellular-scale tree-ring proxy measurements for paleoclimatology.
