n jaoquin river. thank you very much. ad? [applause] >> good afternoon, dan i' from nebraska actually. actually, i'm not but clorado is close enough and will have to do in my point. thosof us from other parts of the couny re looking very cafuy to whatyour doing here and we're earning a lot of great lessonand we hope the sea level rising is a lesson we don't have to learn but yoall, are doing fascinating work. i oad in last night withjoel smith and he said wi wink and nunl, never turn down a trip tsan francisco or new

orleans. we hve one still lef all right. i'm going to talk about a shared resource in the west and my first thing here is alimpoant dividing line on the upper and lower basin colorado line. this photograph was taken lo 1880's and you will see the lower right, the fnder. john lee is actuly my grant grant grand father. you might think it remarkable to be a descendant of the guy, but he had 21 lives and by my count about 2500 descendants right about now. let's go to the next. you probably all knothe overview o the iver. those that never heard of the

colorado river let me give you facts. 7 states and two nations share it. the fastest gowing part of the nation by percentage or numbers. cluding utah, arizona, and nevada and california just on eer numbs. 8 percent of the land area in the united states and it has 60 million acre feet of storage and that's cosest to the highest re e tha35 million people served in an enormouy complicated legal environment what happens after 7 years of drought on the rir. these are two parts that have

50 million of the river in storage and we started out with full reservoirs and you end up with these enormous drops and we're at about 50 percent of the average. underaverage lake immediate will never refill given demands on the system and lake paul will take decades. it estimated ten acre feet per year and that's a serious history record, there's nhing like it. how much is variability and how much is greenhouse gas, no one can say. think you would be silly t think t's solely ntural variability. these two photographs or four actually, lake,meed, looks like

that and the other lake, powell. >> this is courtesy of doctor read mond, you should. he's doing wonderful work on the climate. what we have here is a temperature slide from the lower basin starting about 1890 to current and it looks much like the sli of worldwide mperature.the annual data is red and the blue is $1,130,569 running mean and thistwo degree ahrenheit incrse. the upper basin numbers are comparately about 1 point 5 degrees and in the little inset here you can see, what's happening nationally during that period. you know las vegas wins the record for many many an th natnay
