The important points on man-made global warming can be summed in three items: Item One -- There is no man-made global warming. It cannot be positively distinguished from random noise and natural warming, which is extremely slight and extremely slow. Those who say otherwise are either lying or deluded. Item Two -- If there were global warming going on, humanity could not do anything to stop it, because we are just not that significant on the global climate scale of things. All the money being spent to "fight global warming" or "climate change" is money wasted. Item Three -- If there were significant man-made global warming going on, it would be a very good thing, since the planet is far too cold and has been too cold for thousands of years, apart from brief warm periods, during which all life, including human life, florished. We need warmer global temperatures, and we need much more carbon dioxide in the air, for optimal living conditions.
