Maybe maybe not.
people keep saying that it (global warming) is happening, but the evidence is pretty flimsy in light of previous climatic shifts.
Additionally, even if it is occurring it might be good for human kind...
certainly if the reverse were true (that humans were causeing a global cooling) that would be very bad indeed.
And lastly...Even if global warming is occuring...I've yet to see anything that makes me believe that it is anything more than a natural warming...
Humans can do nothing to stop it.
It's FACT!
