I didn't follow this discussion closely (sorry), same as numerous recent models posted on the web since there is already enough facts to convince me personally in the reality of GW. Incidentally, there was documentary aired yesterday on my "box" - An Inconvenient Ttruth, so I watched it, as New Year holidays, like other people noted, become increasingly boring as years go by ;-)... Oscar prize film, but this in itself impressed me less than facts - statistics - going back thousands of years. Simple graphs, easy to understand for anybody with grade 12 education - Ice Age cycles in Europe, population tripled in the last 60 years, CO2 emissions - both per capita in different countries and per each country (China is #2, but guess who is #1), major contributing factors (not only notorious cars of "our" world, but also burning forests of the third world - this is how they clear land for farming and construction. There is no need to apply models - we already have enough historical data to see the trend. Applying models for plotting probable scenarios (and the film does this) only makes it more scary. If the narrator itself is boring , just skip him, check the graphs: http://www.youtube.com/watch?v=0XMn_Ry3z6M *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
