The first thing to remember is, as any competent climate scientist will tell you, weather and climate are NOT the same thing. A snow storm or a heat wave are weather. Climate is a decades long pattern made up of millions of weather events. Climate has predictable patterns, that can be modeled by computer simulations with some accuracy over decades. Weather is far more variable, and accurately predictable only several days at a time.
There is, of course, a connection between climate and weather. Climate is the long term accretion of weather events. More rainy days, with more inches of rain create wetter climates. And wetter climates create more rainy days with more inches of rain. However, even in the rain forest (climate) it is dry sometimes (weather), and even in the desert (climate) it rains sometimes (weather).
During the midst of the heavy snow storms, the deniers of the reality of global warming, happily confusing weather and climate, were loudly crying "where are the global warming supporters?" "Where is Al Gore?" Ignoring (of course) that models of global warming actually predict an increase in extreme precipitation events including extreme snow storms. But now the worm or at least the weather has turned. See the CNN article: Blistering heat expected in Northeast - CNN.com and a heat waves of historic proportions are gripping the U.S. this summer.
Some very hot summer days are not proof of global warming any more than some very snowy winter days are disproof. But as the climate warms, the frequency of both very hot summer days and very heavy precipitation events (winter and summer) tend to increase. The likelihood of each new summer producing new records for heat increases as climate warms.
So my question is, where are you, global warming deniers? How do you account for this? Do you only recognize the difference between climate and weather when it is convenient for you to do so?
