The way I look at it, the burden of proof is on the researcher to prove the theory which upsets the status quo, in this case AGW. However, I believe that burden also includes providing every opportunity for his skeptics to prove him wrong by checking his assumptions, raw data, reasoning, models, results and conclusions. I'm all for transparency, but there are limits: "Every opportunity" is very open ended, and can lead to the scientist spending most of his time dealing with requests for more and more information, and more and more help understanding it, and more and more help running the models. You may not know the people requesting all this information and all this help expect it for *free*. The standard, instead, are the papers he produces. If they are good ones, they will provide the evidence needed. If the papers don't do that, they may not get published, or if they are, then they don't get much attention, are not cited very often, and the scientist finds himself in the professional dust bin. Besides, the raw data is available (and other resources), and nothing should stop another person from devising his own theories, developing his own models, and ultimately writing papers that don't have the "flaws" he was complaining about. Some have done this, with varying degrees of success. These responsibilities are amplified by the rush to public policy and the extreme costs of such policy. In my view this is absolutely required. There is no rush. The potential for climate problems began to be understood in the '70's, and the science is far better now. It may seem like there is a rush because we've delayed taking action sooner when the problem was smaller. -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly |

Very clearly shown in the the 0degree isotherm for January, see http://etc.usf.edu/Maps/pages/3000/3031/3031.jpg Also consider that the "polar bear capital of Canada" is at the same latitude as the south of England. |
