UPDATE 1: (see end of article)
Nuclear proponents would have us believe that new nuclear power plants should be built in great numbers because, they say, that nuclear power is perfectly safe, reliable, and cheap. It also has no need for importing fuel from nations that would do us harm, plus we can keep American money at home in America. Furthermore, they say, the nuclear power plants produce zero pollution and no greenhouse gas, CO2.
I have written previously on several of these points, disputing each one.
This article has as its main theme the fact that nuclear power is dangerous, and grows more dangerous with each passing week and month. These plants are old, are beginning to show signs of wear and tear, and are dangerously close to creating a nuclear radiation release that will produce great harm. This is based on a just-released report from The Associated Press, found at this link.

Today, June 14, 2011, is an important day in the on-going debate over whether man's activities * cause the Earth's climate to change, in particular to over-heat. The reason today is important is that the AAS, American Astronomical Society, today announced publicly that the sun has entered an unexpected calm period, which could lead to the Earth's cooling similar to another Maunder Minimum (the Little Ice Age of 1645 to 1710). The lack of sunspots is the key issue. It is well-known that the Maunder Minimum period also had few, if any, sunspots.
For more on this, see Anthony Watts' excellent blog, at
* Some of man's activities definitely show up in the measured temperatures, for example, the urban heat island (UHI) effect is quite apparent in many cities. Farming activities that release huge clouds of dust also must certainly impact measured temperatures. Planting greenery and crops, as was done for decades in Southern California as the area was populated, also likely has had some effect on the local temperatures, probably downward.
The importance of the AAS announcement is that there is now a formal, leading scientific body that goes against the "consensus" that climate science is settled, that man is responsible for global warming, and that man's use of fossil fuels is the leading cause. What is more likely is that some warming was caused by the sun's very active state in the past few decades. How can one distinguish between an active sun and its effect, and CO2 and its effect (if any)? We will probably find out over the next decade or two, if the sun continues in its quiet state.
Dramatic cooling can and will cause major disruptions in the Earth's economies and the lifestyles of billions of people. Anecdotal evidence from the Little Ice Age show that growing crops is a challenge. Heating buildings and homes is also a great challenge. Keeping animals alive during brutal winters is also a problem.
More importantly, from a legal viewpoint, California's global warming law, AB 32, can now be challenged as not being based on the best science.
