About this map:
Projected increase in total annual precipitation by 2041-2070 as compared to the 1971-2000 period, assuming emissions of greenhouse gases continue to rise (A2 scenario). Projections of precipitation are highly variable by location, individual model, the timeframe considered. Total annual precipitation is generally projected to increase across the region, but may remain nearly stable or decrease in parts of the Upper Peninsula of Michigan, Northern Wisconsin, and Northern Minnesota.
