Climate Change Science and Policy

What does 'sustainable energy' production mean? After all, there are enough coal deposits in the United States to power our society for 245 years:

That can 'sustain' us just fine. Why all the fuss? Well, I think most people would agree that the thing we want to sustain is a healthy environment in which to live. And even though mountain top removal of coal can look pretty horrendous:








the amount of land affected is probably similar to what a wind farm or solar installation of equal energy generation would affect.

But there is one aspect of environmental degradation that has serious global, not just local, consequences and could hamper the progress of hundreds of generations of humans: that is, of course, global warming from increased CO2 concentration in the atmosphere.

I'd like this blog post to be a place where club members can critique various aspects of the argument over environmental science and policy and, in particular, the emotional byplay over AGW (anthropogenic global warming).

Here is an interesting topic to start you off. Please read this interesting contribution from the libertarian (and environmentally contrarian) Cato Institute:

It is called "What to do about Climate Change?" by Indur Goklany. Interestingly enough, it does not try to contradict the IPCC (International Panel on Climate Change) viewpoint on the future of climate change (like many other anti-enviro blogs). Instead, Goklany analyzes the IPCC's own predictions on water stresses given climate change and comes to the conclusion that global warming actually reduces water stress for more people than increases water stress.

Here is Goklany's statement:

"Halting climate change would reduce cumulative mortality from various
climate-sensitive threats, namely, hunger, malaria, and coastal flooding, by
4–10 percent in 2085, while increasing populations at risk from water stress and
possibly worsening matters for biodiversity. But according to cost information
from the UN Millennium Program and the IPCC, measures focused specifically on
reducing vulnerability to these threats would reduce cumulative mortality from
these risks by 50–75 percent at a fraction of the cost of reducing greenhouse
gases (GHGs). Simultaneously, such measures would reduce major hurdles to the
developing world's sustainable economic development, the lack of which is why it
is most vulnerable to climate change."

I'm basically flabbergasted and don't know how to respond to this. Anyone?
