I finally get it: If GW is not man-made, then God is punishingus with it

The history of the Earth is that the climate is somewhat variable due to changes in its orbit, changes in the activity of the sun, volcanic activity and large meteorite strikes (probably what wiped out the large dinosaurs). There have been major Ice Ages when much of Europe and North America were under many feet of ice, and Inter-Glacial periods when tropical animals such as Hippos frolicked in the River Thames in England. These episodes had nothing to do with human activity! Sure. So? Between the 14th and 19th century there was a cold period known as the Little Ice Age from which we are probably still emerging. We are way warmer than anytime in the last million years. We have only been able to accurately measure surface temperatures for a few hundred years and Carbon Dioxide concentrations in the atmosphere for a few tens of years. In the 20th century there was an 0.7 degree increase in average global temperature, accompanied by an increase in CO2 levels of about 30% due to burning fossil fuels. A good bit higher, and ice core data is fairly close. The relationship between CO2 and the greenhouse effect is well established. Other gasses, like methane, have larger GH potential, but they exist in much smaller quantities and do not persist anywhere near as long. In fact it is impossible to add 40% CO2 to the atmosphere and not have warming. Global temperatures now appear to have stopped rising. Indeed Northern Europe had a particularly cold winter this year. It's all about global averages. Do you really think that global warming says that the earth warms uniformly, each year. In fact 2009 was near (some say tied for) the warmest year on record, and for the southern hemisphere, the warmest. So, your argument is that because mother nature has natural cycles that we should ignore the man made changes. Certain scientists and universities have jumped on to the above correlation between global temperatures and CO2 emissions to extract funding (and personal wealth) from Governments for research into into so-called 'Anthropenic Global Warming' (AGW). Governments in turn are using AGW as an excuse to terrify, control and tax their citizens. In the UK we have suffered massive increases in 'Carbon taxes' on motor fuel and larger engined cars. A lot of our taxes are being given the dodgy third world dictators to 'preserve the rain forests'. They will probably just spend the money on weapons to subdue their own populations and do nothing to preserve the rain forests! Atmospheric CO2 is a food stuff for trees and plants, used in photosynthesis, by the way, Plants fed increased CO2 grow larger but have less nutritional value. A net loss. Warming the poles changes the steering currents of the jet stream, leading to more erratic and extreme weather. The arguments against global warming are of the same type, to cloud and confuse, as those used against the smoking/cancer link. Or against seat belt use (too costly), or so may others. What we do is another matter, but the link is clear. Only those who believe in fairy tales, like Intelligent Design or Trickle Down Economics, disbelieve. Jeff |
