norm miller has done a lot of work on this kind of behavior and he published a paper recently remarking about some of these same scenarios and ot days over this terrain but the message here is, the number of heatwaves gets greater. they begin earlier and last longer both in seasonal context and their synoptic event scale. that's a two day heatwave may all the sudden be a five day heatwave. of course you probably know, just human nature knows if we get more than two days of heatwave we'll run the air conditioner a bit longer and finally give in as far as requiring more cooling, so in california, of course, we have a summertime heat and electrical demand and you can expect that peak power load will creep up because of this. this has the enormous ecosystem implications for this environmental justice issue mentioned earlier, because a lot of people can't afford air-conditioning and ones that can, are going to suffer more or can't will suffer more. evidently there's a geographic issue here. people that can afford to live along the coastline are more insulated than the ones living in colorado
