Montana is predicted to see a decrease in the number of days that the temperature drops below 32 degrees (F) (at least 20 fewer days and as many as Impact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Report40 depending on the geographic location). For the winter it is the increased number of warm days and the increase in precipitation that has the largesImpact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Report

For the summer, it is the days of extreme heat and the lack of precipitation that has the largest effect on the plants that grow within the different Montana ecosystems.Precipitation: Although precipitation is less certain within Impact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Report the more geographically detailed Global Climate Models because of the existence of multi-year weather cycles (like El Nino or the Pacific Decadal OscImpact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Report

Most of Montana is predicted to receive 3-6 percent more precipitation while the northeast portion will receive 6-9 percent more precipitation. The ecologically critical point for precipitation IS when it falls. Significantly more precipitation will fall in the winter and significantly l Impact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Reportess precipitation will fall In the summer. This is especially true for western Montana where precipitation will be 5-10 percent lower in the summer anImpact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Report

The combination of changes in precipitation and temperature may have large impacts on the industries in Montana that are dependent on a climate that many Montanans mistakenly see as largely stable despite Its wide r Impact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Reportange of variability at any given time.Less snowpack in the high country means less runoff for our streams in late spring and early summer, and the runImpact-of-Climate-Change-on-the-Montana-Outdoor-Economy-Dec-2015-Final-Report
