It might not feel like it today, but Chicago and other Illinois cities are seeing more warm fall days than they did 50 years ago.
Why it matters: Yes, we know that some people like a warm fall day, but these increases are driven by climate change and can lead to more mosquitoes, more cooling costs and longer allergy seasons.
The details: The data comes from non-profit news organization Climate Central.
- Of the 246 American cities they studied, 95% saw more warm fall days (Sept-Nov) in 2020 than in 1970.
By the (national) numbers:
- 57% (134) of those cities have warmed at least two degrees.
- 68% (167) have seen at least seven more days of above-average fall temperatures.
Zoom in: Large Illinois towns show varying increases in warm fall days, but they don't seem linked to particular geographical characteristics.
- Quincy: 4
- Champaign: 5.5
- Chicago: 6.5
- Moline: 7.1
- Rockford: 10
- Peoria: 10.6
