The global warming hysteria promoted by people like Al Gore and supported by so many unethical "scientists" are the environmental equivalent of the boy that cried wolf and they are making society the villagers that have come to save the world from the fictional environmental wolf.
We have made so much gains in environmental science, but this latest generation of environmental zealots and charlatans are in the process of totally discrediting the entire profession make society unable to see the real threats from the hoaxes.
The problem is that it is complex and there is real likelihood that a warmer average temperature across the globe would have counter intuitive results.
For example, tornados and hurricanes are not simply linear warmer means more and bigger. If the warmer climate shifts the jet stream, ocean currents, or other patterns, we could see a reduction in these. If there is no shift, yes warmer means more on average.
That's the other problem. On average. As we know the annual variation is huge, and as everybody knows when you roll a few 7's in a row at the craps table, that's going to go on forever.
Neither side at this point is serious at all about seeking the truth. It's just another political football kicked around and the sides are set and nothing will ever change that. Al Gore and all unethical "scientists" and environmental zealots have so corrupted the argument by not doing the only thing scientist should ever do which is to stick to the highest ethical standards which means not making claims that cannot be supported without the highest degree of certainty in a totally open way and allow the highest degree of scrutiny.
A politician thinks of the next election; a statesman of the next generation. A politician looks for the success of his party; a statesman for that of the country. The statesman wished to steer, while the politician was satisfied to drift.
