The scientific community has burned a lot of credibility itself to make any kind of statement to that effect.

That's the thing, the popular impression is that this is the case. But if you read what scientists actually wrote/said you would realize that what science says and what activists and journalists claim science says are quite different. That's why its almost impossible for a journalist to get a quote from a scientists on this topic anymore. Its also why there are almost no scientists who are members of "green" political entities (eg Sierra Club) anymore. Did you see a quote from a scientist in this article? When was the last time you saw one?
