This past July was the hottest month in the recorded history of the lower 48 states. A severe drought and a larger than average summer heat ridge that kept cool weather from moving into the middle of the country contributed to the highest recorded average temperature notched since the government started keeping records in 1895. The July record is part of a larger trend of higher temperatures occurring across the United States over the last few decades, which many scientists point to as a likely result of climate change. Here's a quick look at the hottest month ever, by the numbers.

77.6 degrees: Average temperature for July, which is more than 3.3 degrees higher than the monthly average and 0.3 degrees higher than the monthly record: 77.4 degrees set in July of 1936.
