NASA's gloss on the Earth Obervatory site is measured:
The extreme weather events in Russia and Pakistan have fueled speculation about the role of climate. The GISS release stated, “The location of extreme events in any particular month depends on specific weather patterns, which are unpredictable except on short time scales. The weather patterns next summer will be different than this year. It could be a cooler than average summer in Moscow in 2011.” The GISS release went on to explain, however, that global warming does affect the probability and intensity of extreme events. Climate can drive precipitation because temperature affects the amount of water vapor that air can carry. Likewise, in areas experiencing drought, global warming can increase temperature extremes that exacerbate wildfires.Nothing about the peculiarity of the peculiar pattern, though. And that's the question.
