Even George Bush Jr mentioned the sun was responsible for the weather highs and lows. Now what you forgot to mention that this report likely has to have the Al Gore "Mr Hypocrite personal jet, ocean side mansion dude" seal of approval. These guys likely don't have your knowledge of the sun or are making the report to please the politicians that likely vote on if they are still having a job or if their entire committee even exists so they're kissing political ass is the only answer. Hell my area all summer nights 50's and 60's F and that is unheard of since upper 70's sweltering 80's is the norm even at night and mostly 70's all summer except a few times so this is cooling or just a fluke but not global warming like the summer "late 80s early 90's not sure" where even Alaska was over a 100F for 2 weeks and the lower 48 it was over 3 weeks. People forget what hot really is and you cannot count South California that should be desert if it wasn't for people it still would be.
