16 of the 17 warmest years have been in the 21st Century.
Additional heat will harm Montana’s agricultural production, increasing soil-dryness and surface-water loss, offsetting benefits of longer growing seasons.  Days over 100ºF will double by mid-century.
Since there is a 10% decline in wheat, corn, and rice yields for every 1 degree Celsius rise in temperature during growing periods, as temperatures rise our ability to raise food will diminish. [6a] [6b at p. 8] Scientists predict that if we continue burning more and more fossil fuels, we’ll see around 4 degrees Celsius (7.2° F) warming by the end of this century.
Warming could cause brushfires & damage livestock as shown in the following picture:

Hoot Owl Rules Limit Fishing on Clark Fork, Bitterroot, and Blackfoot Rivers to 2 AM to 2 PM as of July 3, 2015, two weeks earlier than in past seasons, mostly because of temperatures and not water level.
Spruce Bark Beetle infestations are devastating forests in Montana and the West. In Alaska where more than four million acres of trees had died by 2005, scientists, including Drs. Edward Berg and Kenneth Raffa, attributed the infestation to rising average winter and summer temperatures on the Kenai Peninsula. More beetle larvae can survive warmer winters. Higher summer temperatures allow the insects to mature faster, completing a two-year life cycle in one year. Trees, which previously lived in balance with the beetles, have died because they do not have enough natural defenses against this assault.
