Global Warming: are we causing it or not?

Not really...methane is a very bad gas but humans drive tons of cars it's like 100x more then cows.

 

Do some research before posting what you think.

 

if you think global warming is bullshit, ur obviously retarded.... global warming is definatly real... like .. i dont know who said but yes we are a major cause but there are many other factors ..... look at the ice caps..... yea our way of life is definatly helping to melt those big chunks of ice.....but they will definatly melt on theyre own... water passing by arund or through causes friction...will slowly melt the ice even if the water is freezing
