The link L10n74

Here are some links and further comments regarding the last four posts. (Mainly for the post about controversies.)
This is probably the most important issue as far as direct policy implications. (And it is a clear-cut scientific debate.) I have very little first-hand knowledge on the climate change debate. I found links to two blogs on “shtetl-optimized” (Both representing the common views regarding the issue – namely that global warming is caused by humans). The first is RealClimate (that made a good impression on me), and the second is Climate change denial (that did not make a good impression on me).
An interesting paragraph from the second blog in a post about “Israeli climate change denial” (written by Lucy Michaels) is:
“A further aspect of Israeli climate denial, argued by [Pinhas] Alpert and supported by my own research, is that there is a relatively high number of climate skeptics in Israel such as astrophysicist Nir Shaviv who still persists with his Cosmic Ray theory despite it being roundly rebutted by the scientific community. A personal friend at the Israel Meteorological Service is yet to be convinced of the anthropogenic causes. Alpert argues that climate skepticism in Israel represents a Jewish trait based on traditions of Jewish critical learning – to constantly dispute and find alternative explanations. This, I think, is a polite way of saying that Israelis in general are an argumentative and contrary bunch.”
Hmm! (Actually I know Nir Shaviv quite well, here is his blog.) The notion “climate denial” is especially cute.
Our local Institute for Advanced Study will hold starting today a large workshop on “Reducing the Uncertainty in the Prediction of Global Warming” about (mainstream) climate-change science.
Economics, games and psychology
A very skeptical view on the normative or descriptive value of economic theory and game theory (even in principle) is expressed by Ariel Rubinstein (here, and here). Robert Aumann has a very different view. (Look at this paper .)
Rationality and psychology. Continue reading
