"From 1988 to 2020, climate and micro- climate data were collected at the Inga Lake site preparation study. The results, along with a detailed description of as- sociated metadata, have been reported in an unpublished file report. This Ex- tension Note is intended to inform readers about the existence of the file report and how to access it, and to briefly describe selected results. Of primary interest, air temperature and precipitation data col- lected at the research site and nearby weather stations provided evidence of climate change in the geographic area. Both summer maximum and winter ex- treme minimum air temperatures suggest warming conditions; minimum air tem- peratures no longer commonly reach -40°C, and decadal means for winter extreme minimum temperature have become warmer. The frequency and se- verity of growing-season drought also increased during the decade ending in 2017 compared with the three preceding decades. Spruce height growth was ab- normally poor in 2014 and 2016, and we speculate that a combination of drought and unseasonably warm winter to ear- ly spring temperatures may have been responsible."-- Executive Summary.
