Is Global warming a man made Phenomenon?

[realistic]

I've heard so many sides of the story and I can witness it firsthand that Global warming is real. But there is a huge debate in the scientific community on whether it's a man made phenomenon or it's just the planet going through another phase before another ice age.

So people, what do y'all think?

There are two sides to this argument, some claimed its man made.

I think human activities on the earth do exacerbate the Global warming and would make the phenomenon worse. We must do something to save the earth.
