Climate change is not all that big yet. What scientist mean by global warming is only 1 to 2 degrees at a time - which can devastate the ice shelfs.
You are just getting lucky with such a nice summer which comes around every 12 years due to the ocean currents. In a couple years you will be saying, remember that good summer we had a couple years back?
One more thing - don't think that global warming means hotter sunny summers. What it really means is more evaporation of the oceans which leads to more cloud cover and that cloud cover will also contribute to warmer temps. Its a big cycle.
