Man can effect global climate.

when in doubt blame the Chinese
Walmart and the dollar store!

Can humans negatively or positively affect the climate? - Possibly
Can cows negatively or positively affect the climate? - Possibly
How much? - Nobody knows

Nobody really knows if we're currently affecting climate, maybe we are, maybe we're not. If we are, then what behaviors are causing it? Is it really pollution or is it cutting down trees? Is it killing off a lot of insects, animals and so forth that leads to less nature stuff or not? Nobody knows!

But what is known is that we need to keep progressing and we're pretty tough as a species and have lived through the ice age. If we stop using things like plastic, factories and so forth, we'll lose productivity, morale and time for research. The best possible choice in the matter is to continue doing what we are doing, avoid having to force people into the whole global warming hoax, and do what we do best -- evolve.

Eventually within the next 50-years, we'll figure out what's going on and have solutions. If the temperature raises by 3 degrees, then it raises by 3 degrees. It's not the end of the world, and the world will not become a cyberpunk wasteland like MSM wants you to believe.

There's no evidence that humans are the cause of the sudden shift in climate change, but what I do know is that the sun is pretty darn hot. So if you want to blame anyone, blame the sun!
