The chart on the right is the absolute minimum temperature from March 20, 2013.
The chart on the left from March 2012 shows which temperatures were *above average or below average* in that month. It is NOT a temperature chart - as it turns out, the average temperature in Minneapolis in March 2012 was not 100 degrees Fahrenheit.
So the charts show completely different things - but this is how Fox chooses to dismiss global warming: with dishonesty. Click through to see the chart Fox should have used in comparison (which looks a whole lot like the chart on the right) http://mm4a.org/ZR0tUu
