I have a off topic question for those who believe in man made climate change. I am going to use Al Gore as my bases for this question. With the technology available today, hd images, instant video communication with any where in the world, why are speakers like Al flying (and in his case in his protected private jet ex VP and all) around the world to make presentations on the negative impact we are having on the world because of our oil consuming ways? If the problem is that serious why not use tele-presence (video and sound on both sides so he can interact with the audience)? Who would argue with him or other speakers putting their money where their mouth is? Or is climate change just a way for people to exploit us, control us, and profit off us? Lets find an inexpensive and clean alternative to oil but not under the guise of an emergency, lets do it for the right reasons to make a better life for ourselves, cheaper energy, more jobs, less smog in cities.
