As our climate changes, it is predicted that there will be greater variability in annual temperatures, as well as warmer maximum temperatures in the summer. Higher summer temperatures can lead to drought and heat stress to forests, resulting in declines in health and even mortality1,2,3. Here, we assess the change in maximum annual temperature in Vermont. As trees are adapted to the conditions they have experienced, deviations in maximum temperature from the long-term mean (both above and below) could be problematic to forests. Therefore, annual scores are computed as the change from the long-term mean.
