Precipitation in the Chicago area is projected to increase in winter and spring over 21st century, but projections for summer and fall precipitation are less clear

Submitted by sdhandler on

Mean annual precipitation is projected to only increase by 0.7 inches under the GFDL A1FI scenario for the final 30 years of the 21st century compared to the 1971 to 2000 baseline. By contrast, annual precipitation is projected to increase under the PCM B1 scenario by an average of 3.8 inches. Changes in precipitation are projected to vary greatly by season. Both models project an increase in precipitation in winter and spring. They differ in projections for summer and fall. PCM projects an increase of 1.8 inches, while GFDL projects a decrease of 5.8 inches in summer.

Mean annual temperature in the Chicago area is projected to increase by 2.3 ° to 8.2 ° F by the end of the 21st century, with temperature increases across all seasons.

Mean annual daily temperature across the region is projected to increase by 8.2 °F (4.5 °C) under the GFDL A1FI (high emissions) scenario and 2.3 °F (1.2 °C) under PCM B1 (low emissions) for the final 30 years of the 21st Century compared to the 1971 to 2000 baseline. The most dramatic increase in temperature is projected to be in winter for the PCM B1 scenario and summer for the GFDL A1FI scenario. No spatial variation in temperature changes across the Chicago Wilderness region is discernable.

Chicago Wilderness region urban forest vulnerability assessment and synthesis: A report from the Urban Forestry Climate Change Response Framework Chicago Wilderness pilot project

The urban forest of the Chicago Wilderness region, a 7-million-acre area covering portions of Illinois, Indiana, Michigan, and Wisconsin, will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the Chicago Wilderness region to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates.
