Across the state of Ohio, this summer ranks 4th all-time warmest since record keeping began in the late 1800s. Nationally, this summer was also 4th all-time. It wasn't too long ago--last summer in fact--that summer temperatures were cooler than any summer in recent memory. Let's compare this summer's ranks nationally to 2009 and 2008.
2008: 50th warmest
2007: 26th warmest
2006: 41th warmest
2005: 5th warmest
2004: 98th warmest (13th coldest)
2003: 78th warmest (31st coldest)
2002: 4th warmest
What does this mean? Are the temperatures across the state trending warmer in recent years or cooler?
Here is a graph of Ohio temperatures from 1951 to 2006. it shows a negligible increase in overall temperatures.
Keep in mind that this is not a snapshot of what is happening globally. My previous post illustrates the global increase which also note the discrepancy in the data.
