I said in a post not long ago that I remember back in the 70's being told by the media we should fear Global Cooling. I suggested that what actually is going on today with global warming is nothing more than media hype. The media LOVES controversy and fear. That is what sells news.
I also suggested that the climate is constantly changing in cycles and always has. Looking at the long history of the "news cycle" back and forth between global cooling and global warming it suggests that I am right.
I was more than delighted to find this post from the website at www.businessandmedia.org. This article documents the continually changing scares coming from the media dating back to the '20s. It is a really fun read and shows that global warming is in fact created to sell the news. And perhaps to get big grants from the government and other foundations.
