Summertime heat, humidity, and flooding are worse now than several decades ago.
Recent catastrophic flooding during summer 2025in Texas, New York, and Virginia is likely due at least in part to global warming.
While no one weather event can be completely blamed on climate change, extreme weather events are becoming more frequent as a result of our changing climate.
Humidity is getting higher in the United States, and a warmer, humid airmass holds more water vapor which can fall in the form of heavy rain events.
Specifically in the Providence, Rhode Island area, there are 17 more days per year with a heat index above 80 degrees compared with 50 years ago. The heat index takes into account both the air temperature and amount of humidity.
At T.F. Green airport in the Providence area in 2025, the air temperature reached 100 in June for the first time in recorded history.
June 2025 ranked as the third hottest on record globally, behind only 2024 and 2023.
