Without doubt global warming is an exaggerated phenomenon invented by the developed governments of the world in order to increase taxes on the population. What better way to introduce and increase taxes on air travel, rail travel, fuel, carbon emissions, light bulbs, electric. gas, four wheel drive cars, diesel, etc. etc. than to con the public into believing all they are trying to do is save the planet and stem climate change. UTTER BOLLOCKS!  The planet has been around for 10 billion years and managed to look after itself up to now. We've had ice ages, been hit by millions of meteorites, had hurricane's and earthquake's tidal waves and typhhons. Indeed in our 10 billion year history the climate has always changed, just who do we think we our that we are so special that we think we can influence nature . Man has had heavy industry for less than 200 years, the planet has been around for 10 million. Think about it.  Politician = Conman.
