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.

Scary Climate Modes; Universe Today Report (Part One)

A recent post on Universe Today quoted scientists who are worried about two special aspects of the Earth's climate changes. Computer models show that no reduction in CO2 emissions, except to zero, will stop the Earth's climate from heating. Climate scientists also worry about the "tipping point" problem; runaway processes that could occur, that cannot be reversed. (See my Feb. 4, 2008 post on the same subject.)

For the computer models, the old, Greek philosopher Xenophon may have been onto something, when he proposed that you cannot walk across a field. To do so, you have to walk halfway, then half of the remainder, then half again, ad infinitum; and you can never get there. Good silly fun, but just suppose that it relates to what the computer models are finding.

A very good book on Earth's geologic history, Stepping Stones, by S. Drury (1999), said that in 1997, the CO2 emissions were about 30 billion tons. Furthermore, one half of the CO2 is sequestered in the ocean as calcium carbonate, in the rain of shellfish exoskeletons to the ocean floor. If we could cut CO2 in half to 15 billions tons, we would seem to be home free; 15 billion tons could be sequestered. However, according to theory, the ocean would still only sequester one-half, or 7.5 billions tons, and so on, and so on.
