If you follow the debate about global warming you might be inclined to think there are two sides of the debate. On the one hand you have the majority of scientists that hold to conclusions put forward by the IPCC. Global warming is real, is man made, is a serious problem and should be addressed. On the other hand you have the skeptics. It's not even happening, or if it is it's not man made, or if it is we shouldn't do anything about it.
It's worth noticing that there is another view skeptical of the IPCC conclusions and in my view this position seems to have more credibility. The people that adhere to this view often have impeccable credentials. Their view is that things are much worse than the worst case IPCC projections. See for instance here. Why is it that we never hear from these global warming skeptics.
