New results from the National Oceanic Atmosphere Administration show that July 2012 was the hottest summer on record for the United States, since accurate record keeping began in 1895. With an average temperature of 77.6 degrees Fahrenheit, last month's heat wave surpassed July 1936 (which recorded an average of 77.4) to become the steamiest summer around.
In a report on NBC, NOAA climate scientist Jake Crouch explains:
"These events are kind of what we'd expect with climate change, we'd expect expanding drought, we'd expect warm, record breaking temperatures… But it's kind of hard to pinpoint this month or past several months as a telltale sign that climate change is happening. The drought is more of a local factor and isn't necessarily driven by large scale climate change, but is impacting local temperatures. But we've also seen an increase in U.S. temperatures overall."
