I know there is no limit to how many zeros we can write between "1" and "hertz". Is there a limit on what can actually be emitted based upon the properties of known elements (or any other criteria)?

In the last week i have seen more shows on TV about global warming than there has been in the past several months. About 6 months ago, there were no TV shows about this, at least not as many as now.

Yes, Katrina happened, The Europeon heat wave happened, slightly mild winter across the US. But why so recently is this getting so big so fast? I just seen a show that said we are not sure when the breaking point is of global warming and that it could be irreverseable.

Any links would be appreciated.
