A recent study by alarmist Philip W. Mote, director of the Oregon Climate Change Research Institute at Oregon State University claims that global warming is 20 times more likely the cause of last year’s heat wave in Texas which was directly causational to the overwhelming emissions of CO2 into the atmosphere.
The study, which covered the 2011 weather events , was rushed to be ready for publication by February of 2012.
The study entitled, “Did human influence on climate make the 2011 Texas drought more probable?” surmised that even though it was probable that the drought was responsible for the heat wave, Mote decided to interject that it was more probable that human influence was the ultimate cause of the extreme temperatures.
Mote is convinced that while scientists are not 100% sure that human influence is an encompassing cause of “extreme events” and they are not without doubt about the response the biosphere has to “the stuff we’re putting into the atmosphere”, nevertheless, “We are, in a sense, setting up our descendants for a set of weather events that may cause varying degrees of harm. And the less greenhouse gases we put into the atmosphere, the less harmful those events will be.”

Officials at the San Onofre nuclear power plant in California have admitted that conditions at the plant are worse than they anticipated.
Daniel Hirsch, a nuclear expert at the University of California, Santa Cruz, commented: “This reveals a far greater problem than has been previously disclosed, and raises serious questions about whether it is safe to restart either unit.”
The Nuclear Regulatory Commission (NRC) has downplayed concerns that prompted an investigation earlier this year when one reactor was closed. Published findings show that more than 3,400 steam generator tubes in the new steam generators at San Onofre have undergone some sort of damage — as well as about 1,800 in Unit 3 and 1,600 in Unit 2. Those tubes are instrumental in keeping the site’s 65 foot tall, 1.3 million pound generators up and running.
The aging facility, now more than a quarter of a century old, is in multiple stages of deterioration, yet it has not been scheduled for shut down. This endangers the populations living in the surrounding areas.
More than half of America’s nuclear power plants are suffering from wear and tear from aging, according to theNuclear Energy Institute (NRC). They point out that these facilities were intended to be used for 40 years, and they are now being pushed past the 60 year mark.
Now it has been concluded through research that 75% of the US nuclear power plants are leaking massive amounts of radioactive substance into local groundwater by way of corroded piping. The NRC has actually lowered their official standards to accommodate the reactors that are working below acceptable levels. Tritium, a dangerous carcinogen, is responsible for boosting cancer incidents. The US government’s response to this is to raise the acceptable exposure levels for the nation.
Propaganda keeps the nuclear programs in the US running passed their time under the guise of cheap power with no greenhouse gas emissions. Yet, nuclear only accounts for 20% of the US allocation of electrical power.
The 23 reactors that are beginning to give warning signs that they will fail in the near future are of the same Mark 1 design of those at the Fukushima Daiichi nuclear power plant. General Electric (GE) is responsible for the Mark 1. GE claims that the Mark 1, originated in 1972 is a safe design. “Critics say its containment box is too small and its walls are too thin. They also say the waste storage pools, situated several stories above the ground over the main reactor and outside a key containment vessel, are vulnerable to terrorist attack or meltdown.”

We have heard much about Japan’s Fukushima Unit 4 nuclear spent fuel pool and the huge amount of radioactivity that could be released if that pool were to go dry, crack, fall apart or collapse (1; 2). As former Japanese diplomat to the United Nations, Akio Matsumura, recently warned the world:
The highly radioactive spent fuel assemblies at the Fukushima-Daiichi power plants present a clear threat to the people of Japan and the world. Reactor 4 and the nearby common spent fuel pool contain over 11,000 highly radioactive spent fuel assemblies, many of which are exposed to the open air. The cesium-137, the radioactive component contained in these assemblies, present at the site is 85 times larger than the amount released during the Chernobyl accident. Another magnitude 7.0 earthquake would jar them from their pool or stop the cooling water, which would lead to a nuclear fire and meltdown. The nuclear disaster that would result is beyond anything science has ever seen. Calling it a global catastrophe is no exaggeration. If political leaders understand the situation and the potential catastrophe, I find it difficult to understand why they remain silent. The following leaves little to question:
1. Many scientists believe that it will be impossible to remove the 1,535 fuel assemblies in the pool of Reactor 4 within two or three years.
2. Japanese scientists give a greater than 90 percent probability that an earthquake of at least 7.0 magnitude will occur in the next three years in the close vicinity of Fukushia-Daiichi.
3. The crippled building of Reactor 4 will not stand through another strong earthquake.
4. Japan and the TEPCO do not have adequate nuclear technology and experience to handle a disaster of such proportions alone (3).
It really does make one wonder how all of the world’s aging reactors will be dealt with if there is a global economic collapse.
What we are witnessing as events race forward appears to be the convergence of socio-economic collapse — the 500-year-old banking system based on fraudulent accounting tricks — together with the crumbling and cracking of the faulty technostructure put in place in the last century. Roads and bridges fall into disrepair and cities like Detroit will simply revert to green farmland, a natural process of the cycling of ecosystems where humans play their role and then bow out once they have exhausted their industrious energies. In the case of nuclear power plants, the waste remains radioactive for a good 10,000 years and the process for safely storing it has not yet been invented (4).
