Take a look at this: http://www.naturalnews.com/020649.html
We're talking about 30 percent of the world's land surface becoming essentially uninhabitable in terms of agricultural production in the space of a few decades
130k years ago it was around three degrees Celsius hotter than it is now. Was 30% of the world's surface uninhabitable in terms of agricultural production then? Of course not. The temperature won't rise more than three degrees Celsius in "a few decades." Even the most recent and extreme models have it rising no more than 8 degrees Celsius in a century (and that's with acceleration over time).
When I was growing up, I thought that liberals were grudgingly accepting the terrible facts of global warming, while conservatives were turning away from those facts and embracing some made up story, because they were afraid of the changes that those facts would induce.
Now it's not so clear cut. Of course people like Rush Limbaugh are certainly turning a blind eye to what is overwhelming scientific consensus, and making up their usual story, where nothing is wrong aside from liberals trying to mess with people all the time. However liberals, whom I previously thought were merely grudgingly accepting the truth, actually have a made up story of their own. One where suddenly the sea level rises ten feet, thirty percent of the world's land is unfarmable, there's mass starvation and millions of refugees, megahurricanes decimate humanity and methane fireballs of doom streak across the sky.
Now many will believe stories like this if they're told often enough if they're neutral on the matter. However to make up and help spread these stories, to write the articles, make the movies and argue the points, I'd imagine you would need to want for this story to be true. This completely baffles me, I don't understand why anyone would want such a terrible story to be true.
As for myself, I don't want global warming to be true because it's a sad story, so I keep trying to find evidence to refute its various claims. However it's a complicated subject and I haven't been able to find strong evidence against all but the wildest claims. For instance when MIT says that their models say the world will warm five degrees Celsius over the next century, reaching its highest temperature in over a million years, I really can't argue against that. I mean I know where to find well done critiques of climate modeling, but I can't argue with MIT...
