To the answer to the question of global warming is a sticky issue. There is no doubt that there is more carbon dioxide in the atmosphere and it is obviously due to human industry. The second article of the readings was arguing that the average surface temp. of the earth has increased. But this point isn't even debated by the majority of the scientific community. I don't know many people that think that the carbon content of the atmosphere hasn't increased or that the avg. temp isn't up a half degree or two. But what the real issue should be and what i don't think is being talked about enough is the real effect that this temperature increase will have. Oreskes barely touches the issue, but Lindzen claims that the experts he has talked to say that the earth and the human population could readily adapt to a change of 1-2 degrees of temperature increase. Even if the carbon dioxide levels doubled in the upcoming years how much would our avg surface temperature increase? The current models for these extrapolations can't be seen as truth. Even some of the models, according to Lindzen, can't even correctly predict what has already happened. Global Warming is happening but what is the impact going to be on our population? Can we do anything to seriously curve the trend? Our climate isn't a simple matter and trying to understand it is a mammoth task. The global warming debate, in my opinion, should move away from proving temperature increase but focusing on its impact on human civilization.
