The individual GCM projections have less agreement about whether average annual precipitation will increase or decrease in our region by 2050. Precipitation is rain, snow, sleet, or hail that falls to the ground. The role of precipitation has been especially difficult to discern from existing studies, due in part to habitat and behavior characteristics of specific vector species and because of differences in the temporal and spatial scales of the published studies. Since 1970, the annual average temperature in the Northeast has increased by 2°F, with winter temperatures rising twice this much.4 Warming has resulted in many other climate-related changes, including: More frequent days with temperatures above 90°F ; A longer growing season; Increased heavy precipitation USA climate varies dramatically by region.
