global warming,climate change,it's all just a huge international con.the earth has over millions of years had numerous climatic changes,tropical forrests in northern europe,ice ages with ice sheets down to the mediterranean.to think that in the few hundred years that humans have monitored the weather,we suddenly predict massive climate change within a short period of time,utter nonsense !it's all a conspiracy to control our behaviour,preserve limited fossil fuel reserves until viable alternatives can be developed.it also diverts our attention from real issues such as world poverty,starvation,child labour and numerous other disasters that we could all do something now to resolve.those protesting at heathrow are part of a professional band of "tree huggers"who may be well intentioned,but are so far off target it beggars belief.numerous scientists express dismay at this global warming brainwashing which is being drummed into us at such a rate, the authorities hope eventually we will all believe it.aviation does produce carbon,so does most industrious human activity,even living in a cave with a log fire is damaging to the enviroment we are told.just accept,we are being conned !
