People talk as though the evidence of catastrophic global warming were unequivocal but nothing could be further from the truth. Here is a newly released
study that presents a very different picture, the
Fallen Angels scenario.
In my mind, its too early to change policy. First, we need to really understand the nature of climate and the impact of industrial activity. As near as I can tell, we don't yet appreciate the natural variability of climate, much less whether our activity is harmful or not.
I certainly hope that the next ten years doesn't throw the climate into catastrophy because we need that time and more just to make sense of what is happening.
