No, this doesn't have anything to do with UFOs. Or, does it? It could. Make your own connections. I suppose we could say there's a connection in the sense of Pelicanist behavior; the leaders that be continue to ignore, cover-up and disseminate disinfo about both UFOs and global warming.
Alfred Lehmberg, on his blog Alien Views, has a recent piece about this: Slow Death.
Dustin, on his Odd Things blog, has a recent piece on global warming.
If you haven't seen An Inconvenient Truth yet, why not, and, see it.
The war, er, occupation, is horrific, and so are dozens of other issues; poverty, child abuse, animal abuse, etc. And while global warming may seem boring, daunting, overwhelming, and not sexy enough, the reality is this: if we don't focus on this and fix it (and being as how we're the biggest contributor to the problem, with the least amount of responsibility) we won't be around to worry about the other issues.
