One can argue about exact amounts, but the fact that the rate of change is higher than has been found during any previous period should, when considered in combination with the many other, independently-developed, methods for looking at temperature change, lead an open-minded person to conclude that 'this isn't normal'. No knowledgeable scientist has ever stated that the temperature is on a straight line increase. As you mentioned, nature varies and year-to-year and season-to-season the temperatures at a particular place are going to vary, both warmer and cooler. The presence of a hot summer or a hot year (or a couple of record hot years) does not prove there is warming, just as the presence of a colder than normal winter doesn't prove there is no warming. These are just variations around the overall averages, which is where the proof is to be found. <br /> In fact, one CAN'T detect 'global' warming at any one location, and this is because of exactly the types of things you mentioned. It is only by combining measurements from all over the world that one can be sure there is an overall change taking place.<br /> I'll finish by pointing out that the models of even the early people looking into the potential for there being warming predicted that such warming would result in parts of the planet getting warmer while other parts get colder, and that one of the outcomes of the rate of overall increase was an increase in the variability of the temperatures at individual locations.<br /> There are lots of questions and uncertainties that remain about how much and when and why. The only thing that at this point can't be effectively argued by good science is that the overall global temperature is increasing at a rate faster than one can explain without attributing part of it to human activities.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-266108914902271629.post-66994898011944924612009-12-15T18:59:15.378-08:002009-12-15T18:59:15.378-08:00Even if there weren't global warming shouldn&#...Even if there weren't global warming shouldn't we kick this crack-oil addiction of ours? Do we really need to find out just how polluted we can make this planet and get away with it? If the global warming doubters are wrong, we're doomed. If the scientists are wrong, we have a cleaner planet. Also let's not confuse 'weather' with 'climate'.

The icecaps in Greenland and the poles are melting (I live in the Netherlands, half my country is below sealevel) If you don't believe in globalwarming, the least thing anybody should do is to make sure we dont reach a point of no return, just in case . . .<br /><br />Enrico.Anonymousnoreply@blogger.com
