Is global warming a real concern, or just a popular fad?

It's really hard to know for sure. There's a lot of "proof", But, on the other hand it's a great story for the media and a great common enemy for government to rally the troups. So, I say FAD. For a more balanced view than what you can get from the popular media, check out http://climatedebatedaily.com/ and make up your own mind. BTW - let me know what you think.

If you could have 1 superpower, what would it be?

Quite simply, if you could control peoples actions and thoughts then you wouldn't need any other super powers. You could get the strongest superhero to do the heavy lifting, the smartest superhero to do your end of year taxes, and the most cunning superhero to make loads of cash for you.

Or you could just make everyone pay you 1% of their income every month and tell them to be REALLY happy about it! Times 5bn or so people, that's a lot of cash to keep you going. If you wanted to do some fun stuff, you could make everyone believe you were invisible whenever you wanted (some people already have this 'skill' except it's all the time - especially in corporate world)

You could make every woman on earth believe you were the greatest guy that ever existed, and every guy believe that you were the shining example of a perfect role model.

Basically, since true power is in the mind, thats got to be the place to start!
