Global Warming or just part of a normal pattern?

Today’s New York Sun has an interesting article about last month’s heat wave. What was interesting is that the article stated how “July 2006 is still second to July 1936”.

I’m just going to go out on a limb and guess that in 1936 there wasn’t any global warming. So the question is if the 120+ degree temperature experienced in 1936 wasn’t global warming, why should I believe that the heat wave of today is because of global warming and not just a normal change in weather patterns?
