This show gives an excellent account and definition of Global Warming. Tom Brokaw give a very informative narrative, while traveling throughout different parts of the world to give a first hand account of just how global warming is affecting our planet and its' inhabitants. After viewing this show I started checking its' sources and doing my own research; after which I am quite convinced of the warning it gives. If the present state of things are not changed the inhabitants of this planet will be in for some drastic changes. Good news for insect populations, bad news for us mammals. I would recommend viewing this to anyone who is curious about global warming, but does not feel informed enough about it. I have also come to find surprisingly that there is zealous opposition to global warming. In my home state of Ohio especially. After viewing this program I have come to the realization that these people are nothing more than just ignorant and would be enlighten by thinking for themselves and taking the initiative to do there own research and stop relying on narrow minded associates to convince of their own unfounded ideas.
