| First off everyone needs to stop saying global 'warming' and use the term global climate 'change.' There exists no data to show a correlation between the current warming trend and greenhouse gas emissions. Yes the greenhouse effect is a plausible theory and if we had a static atmosphere may well be the deterministic state of our atmosphere. But it isn't. Second, the hockey stick temperature graph does not portray the true nature of our climate dynamics. There have been much larger warming events in the past (when humans were around) that have not been directly linked to any man-made cause. Third, no climate model exists which accurately portrays global dynamics. At best the existing models can reproduce a feature of the current warming trend if the parameters are twiddled to do so. However, they then fail to reproduce local characteristics (local as in the polar regions). In addition, these models fail to determine important parameters in the system such as the specific heat of the lower atmosphere. Finally, the news media across the world has been highly irresponsible in reporting science. They often use images to depict global warming that have no relation to any climatic change and are natural processes. The calving of glaciers for example. A natural and ongoing process. They also fail to put into perspective other processes including glacial advance and recession. Note: most receding glaciers have slowed their recession in the past 20 years and still more are advancing. Finally, they take events out of perspective such as natural disasters (which we still do not understand the cause of) and habitat change. The perfect example being polar bear deaths. The media jumps to this as a sign of polar melting while overlooking the overfishing of spawning waters of the bears food source and the well established fact that fish have begun to swim in deeper waters. The bottom line, don't use the media as your sorce for scientific information, read the large international reports that have come out not of think-tanks but from scientists who do the research. Your taxpayer dollars pay for that, the commercials pay for the news.
