The greenhouse effect is a perfectly natural thing yes. If it wasnt for the "natural" amount greenhouse gases in the atmosphere,the earth would be a very cold place,and in an ice age!. Thing is over the last 150 years of burning fossil fuels we have added billiions and billions of tonnes of greenhouse gases to the natural amount,thus making the planet warmer. Also we have destroyed almost all the forests of the planet,which are carbon sinks. The bio sphere is now starting to reject all the harm we have done to it over the last 150 years. Soils are no longer acting as carbon sinks,and oceans the same. Also as the ice in the artic melts it will expose millions of tonnes of methane gas,and release this into the atmosphere,which will speed the whole process even more.
