For the same reasons we make fun of climate-change deniers who say "look at this record cold winter; there's no global warming" means we can't use a historic heat wave to say "look globaal warming".

We make fun of the climate change deniers in this scenario because the cold winter often is evidence of climate change. Record heat waves can also be evidence of climate change.
A heat wave (like other weather) by itself isn't evidence of global warming, but extreme weather events like this (and like extreme winter storms) are made more frequent by global warming. You should expect to see more "once in a millenium" weather events as the planet continues to warm.
