Nuclear Energy Can Save US--America�s 100 nukes equal four million barrels of oil per day.

Billions of lives and civilization itself may be at risk from the Global Warming & End of Cheap Oil, Crisis. Rising sea levels and rising oil prices could be the end of civilization as we know it. The problem is so huge that the most powerful answer, many nuclear plants, must be deployed. Currently, America‘s 100 nukes deliver the energy of four million barrels of oil per day. Wind and solar cannot do the job, and may delay the real answer too long. Still, all kinds of clean energy, plus conservation, plus reducing deforestation, will be needed to help the poor half of the world, and for civilization to survive through this century.

Reprise: Will the Earth Get Hotter or Colder?

Why is the Earth's weather an emotional, political subject? There are scientific facts that can be found, and that should be reported precisely, so that over decades the public can clearly see how the Earth is doing. Scientists of good will can debate what the facts mean, and over time the public will come to understand who is on the right track.
The following statement was in my July 30, 2007, post: "Within the Little Ice Age, another drop of 3-degrees F, occurred worldwide for 70 years (1645-1715), due to lower Sun energy, in the so-called Maunder Minimum of sun spots. Sol is a slightly variable star. If such an event occurs now.....it would offset Global Warming to some extent." However, the world may get more than I bargained for. The WWW.dailygalaxy.com (2008/06), reported that there are currently no sunspots on the sun, and that the world cooled 0.7C, in one year through January 2008. Whether no sunspots means cooler sun is still debatable. This is the minimum period of the normal sunspot cycle, but some say “the sun looks dead” and some others are worried about how long it will continue.
In Nature, 326:52, 1987, Ribes E., et al, reported that during the Maunder Minimum of sun spots, the sun’s angular diameter was larger, and rotation slower, probably leading to a cooler sun for 70 years. This would certainly trump any human influences.
Per a statement in Scientific American, the ocean level rises two millimeters each year. Why do we not take a million or so satellite readings each month, and report the actual mm rise, even to the second or third decimal place? Why don’t we average millions of temperatures worldwide and give the Earth’s temperature each month as well? Why don’t we also measure “The Solar Constant” (misnomer or not) by satellite, and tell each month whether the sun is giving more or less heat? The heat may or may not relate to sunspot activity, but in decades, we should know where we stand.
Regardless of the climate, air pollution from fossil fuels, especially coal, will still be a problem, and fresh water will be critically scarce. Thousands of nukes, or millions of wind turbines, or some combination, will still be needed to get us through this century.
