PITTSBURGH — “It’s not usually this warm.” The norm could be changing in years ahead, according to the data.

Warmer weather in Fall months has been extending longer and longer. In the past 50 years, warmer weather has increased in length by nearly 15 days. In the 1970s, the last 80-degree day would be in late September. In recent years, the last 80-degree day has been in early October.

If this trend continues, it could cause a disruption in agriculture, migration, and hibernation. The invasion of warmer temperatures in colder seasons could bring a challenge to plants and animals that usually rely on seasonal changes.
