I honestly am not sure which of the following statements are true:
1) Global warming (or more specifically, global climate change) is not happening at all, period, end of story. Much like the heterosexual AIDS scare of the 80s/90s, it is simply a fabrication of the media and 20 years from now, we’ll be thinking “Whatever happened to the whole global warming thing?”
2) Global climate change IS happening, but it is natural. It is overwhelmingly due to the activity of the sun or other natural phenomena with a microscopic man caused portion, and even if we stopped all carbon related activity whatsoever, there is essentially nothing man can do about it. (Even if this one is true, it doesn’t mean global warming is necessarily a bad thing. There are many reasons to think that global warming would actually be a net benefit for mankind.)
3) Climate change is happening, it is caused by man, but we shouldn’t do anything about it because it’s either not going to be catastrophic, or at the very least not worth the cost because the benefits of energy use outweigh the costs of rolling back carbon emissions. This is the view of one gentleman of whom I am a big fan, Bjorn Lomborg. (click the link! it’s good!)
I am certain, however, that the following is false:
4) Global warming is happening, it will be catastrophic, it is man’s fault, and we must act to stop it now no matter the cost.
The last statement seems to be the point of view of the most of the world nowadays. It certainly seems to be the view espoused at UK- at least in my Geography 160 class (Dr. PP Karan).
However, the founder of The Weather Channel John Coleman seems to think #1 is true, and he is talking about suing over it.
Can I just ask: if the guy that founded TWC is not convinced global climate change is happening, should you be?
