The greenhouse effect has never been proven and it is therefore garbage.
If you're going to cite something that is completely wrong, but you believe to be true, please use some references, rather than off the top of your head.
Climatologists and scientists all agree that there is a link to the increased global temperature caused by the dramatic increase of CO2. There is substantial evidence to prove the greenhouse effect and global warming. Try googling it... ¬_¬
But even if the greenhouse effect were real, our carbon emissions excluding the natural ones are so miniscule compared to the amount of Carbon naturally put into the evironment by humans, other living things, and natural processes. Therefore our use of cars and such will not effect annual tempurature changes.
Thats also completely wrong. The concentrations of Carbon dioxide have increased by 31% and methane by 150% over the past centrury. In the past 40 years the global CO2 concentration has increased by over 75ppmv (increased by 25%). The sudden increase and build up is clearly caused by increased industrial process and deforestation and hardly the effect of respiration or similar.
Also your point about cars is also incorrect. Vehicles are one of the main CO2 producers of the past 50 years and especially aeroplanes who produce around half of the carbon dioxide annualy.
At the current rate, carbon dioxide conc. are going to rise even further. We have more industries and significantly less forestation. This is why greenhouse gas concentrations need to be reduced to slow the increasing temperatures.
If you're truly deluded enough to think that global warming is a falsehood conjured by your goverment... then seriously you need to do some research and stop acting so arrogantly, as future lives will be at stake.
