Query: Opinion masquerading as science

While parts are interesting, the overiding message comes off poorly substantiated and reads mainly as opinion weakly supported by data. In fact, there are almost no direct references for the purported facts reported which leaves the reader wondering if much of anything in the book can be believed. Unfortunately, when he got on topics where I have direct knowledge, he exagerated secondary drivers and largely glossed more significant factors. This is either due to naivety or perhaps because fact didn't fit the 'script' - or a mixture of both. He tends to seek special cases to justify a general conclusion. As with most subscribers to the doomsday scenario he seems to be picking factoids to support his story but isn't looking at the big picture, probably because the big picture shows his case to be without much merit.
