How your comment got modded Insightful is a mystery. You don't give any arguments, you just postulate.
Humans can't even make it rain or change the weather locally
Really? Just one example: the notorious London smog. Most major cities used to be covered in the filthy stuff until burning coal in cities was largely banned; does that not qualify as weather? It certainly changed the atmosphere in large, local areas.
Anyone who thinks they can affect the whole world this much is a moron or shill for some environmental group
Hmm, right. Another example: man-made plastic pollution is now found everywhere - with the possible exception of Antarctica. You find it everywhere, even in the middle of the Pacific, and it does in fact affect wildlife. Or how about the fact that manmade chemicals can now be measured in just about every sample of water you can come about? The truth is that mankind does in fact influence every environment on the planet; the good news is that this also means that we can choose to use our influence to make things better.
But it's certainly not manmade
You know that, do you? How? Evidence, please.
correlation does not equal causation
However, it does equal correlation - and correlation means there is some sort of connection. Climatologists have come up with some very likely explanations, unlike you.
How else do you explain the many periods of warming and cooling in the past long before humans even existed?
That one is brought forth all the time, but it is a nonsense argument. The only thing it proves is that climate change can be caused by other things than human activity; nobody has ever denied that, and in fact, for many years the preferred theory was that we didn't affect climate, but we have had to abandon that idea, because the observable facts speak against it.
I rest my case before the nuts here censor my message
As you already knew, nobody was going to 'censor' your opinions. In fact, you have been modded up - strange as it seems. But you just had to try to milk the 'freedom of speech' card for what it was worth, didn't you? You should be ashamed.
