It seem to be good to start the 1st day of 2008 to know some truth about the earth we are living, so I watched the movie "An Inconvenient Truth" this afternoon. Turn out it's not about earth, it's about what we, as human being, has done to the blue planet.
Al Gore goes around the whole US and places in Europe, China, Japan, Korea. Presenting his slide show thousands times, he has brought up much awareness of global warming. His slides presenting the scientific data to display how's the temperature going up over the past 15 years and the consequence of glacier's melting, rising of sea levels. And with the increasing of CO2 and pollution, the temperature is still keep going up. If we didn't face the fact and act on it, we are going to face a serious climate threat in 50 years ahead.
I have heard about it since a few years ago. Al Gore got a lot of resistance on the acceptance of the threat from medias, related energy or utilities corporates, and opposite political party. There are many who doubt about it and call global warming might not be something "proven" yet. Michael Crichton's book "State of Fear" seem to be one of the reference, although it's a fiction. I found this to be interesting, as Michael claimed he spent 3 over years to read through tons of articles/documents (the book has 20+ pages of reference citing articles from scientific reference) and he has his view point that the cause to the warming is yet unknown and not proven.
(disclaimer: I have not yet read "State of Fear", I learn this from people who have read it and some search on Internet)
Now, without further study or research, how do we as a ordinary person to judge? Obviously, Al Gore seem having more hard proof/data, he's awarded Nobel Piece Prize of 2007, and he has a supportive team to study and help to educate/dispatch the truth. And yet Michael Crichton is on his own, I still seeing some people arguing on newsgroup to stand on his point!
All I wanted to say is, I find this amazing. The story telling is always a more powerful and convincing channel to convince people. The changes of weather is pretty obviously observed and the disasters in recent years show us something is really happening. It's probably a matter of dispute of whether CO2 is the main cause or is that again some conspiracy theory against big corp/government. I should go to read the book and figure it out.
Note: Wikipedia's "State of Fear" entry contains links of scientists's refuting of the inaccuracies in the book. Nevertheless, it should still worth a read.
