Creationism and Science
As fundamentalist religious thought strengthens its hold on U.S. politics, and increases its role in politics around the world, enlightened values that form the very foundation of modern society are coming under attack. In the United States the wedge issue being used by fundamentalists is a pseudo-debate over creationism and Darwin’s theory of the descent of man.
Seawater pH and anthropogenic carbon dioxide is the first chapter in Climate Change, Ed: Siddhartha P. Saikia (International Book Distributors 2010).
In 2005, the Royal Society published a report titled Ocean acidification due to increasing atmospheric carbon dioxide.Â The report’s principal conclusion “that average ocean pH could decrease by 0.5 units by 2100” is demonstrated here to be consistent with a linear extrapolation of very limited data. It is also shown that current understanding of ocean mixing, and of the relationship between pH and atmospheric carbon dioxide concentration, cannot justify such an extrapolation.

Pope Benedict XVI interleaved two themes in his talk at the University of Regensburg on September 12, 2006. These are discussed here in two separate parts: Truth, Faith, and Reason and The Dialogue of Cultures. The first addresses the Pope’s proposal to expand scientific reasoning to include the “rationality of faith”; and the second with the threat of radical Islam, and whether a “dialogue of cultures” is possible if the West persists in its belief in what the Pope calls a “reason which is deaf to the divine”.

“We are about to waste an enormous amount of money and effort on carbon mitigation without lowering CO2 emissions one whit. The Goracle and his fellow travelers will carry the day.”
AL GORE won an Academy Award for his skillfully done film, An Inconvenient Truth. It was well-deserved. Had he given as good a performance during his campaign for president, he would have won in a landslide. As environmental drama, it only can be compared with Michael Crichton’s novel, State of Fear. Both have elements of scientific and political fact, and both are excellent fiction.

Socialism, the Left, and its future in the United States.
The Left in the US is in crisis. It has lost the broad support it once enjoyed in the working class and finds itself captive to the pastâ€”or, worse yet, to an impotent radicalism. It no longer offers working people a political outlet for their interests, but only a means of protest about issues that are not central to their lives.
