> [...] global warming [...] either cannot be generalized globally or did not start in 2010

I guess global warming _can_ be generalized globally?

It sure didn't started in 2010 but neither did social networks.

Facebook opened public access in 2006 which about the same period when Twitter was launched.

_An Inconvenient Truth_ was released in 2006 and it seemed like the start of a global discussion about global warming. And behind _global warming_, there's actually the overall destruction of our environment by mankind.

I agree that social media is a cause, but the given arguments cannot exclude _global warming_. Quite the opposite.
