Global climate change could be because of natural origin, anthropogenic origin, or combination of both. Humans do contribute to global warming, although the scale of contribution (as in how many temperature increase have it been causing) is not easy to tell.
To prove how anthropogenic activities can cause global warming, just take a look at fenomena of why up in the mountain it is usually colder than that in lower altitude, even though the mountain is closer to the sun than that the sea level.
Hint: air density

Another hint: greenhouse gases produced by human continuously are trapped in the air, mixed with all other gases.
My two cents. =)
