Was that climate change? Scientists ponder a deadly July 4 weekend
Scientists say climate change made the deadly heat more likely and more intense, with early July temperatures reaching 100 degrees in some areas.
On the Fourth of July, scientists identified the "fingerprints" of climate change in a deadly heat wave, noting that extreme temperatures are now at least three times more likely to occur.
A high-pressure system settled over the country, bringing sweltering conditions that matched or broke many temperature records across 10 states during the holiday period.
New Jersey authorities reported 29 deaths related to the heat and complications it created for people with preexisting conditions, officials said.
Temperatures in Farmingdale, New Jersey, approached 100 degrees Fahrenheit, though heat warnings have finally faded for much of the eastern region.
Researchers expect these heat waves to become more frequent as climate change makes extreme weather events increasingly likely in coming years.
