"The results suggest that previous estimates of the heat stored in the upper 700 meters of the ocean since 1970 have been too low. In the Southern Ocean in particular, they estimate past heat tallies were 48% to 152% too low." Let's start with the 48% number. What do we need to get the new estimate from the old estimate? Multiply the old estimate by 0.48 and add that to the old estimate. Simplified, just multiply the old estimate by (0.48 +1). For the 152% number, it would be a factor of 2.52.

Thermal energy can be added to or released from a system so there is no problem using a negative sign when describing it. But that is not what is going on here.

More about counting hairs that splitting them. Matt 10:30

Someone commented above about C. S. Lewis, but Madeleine L'Engle has also used ET to examine religious themes. http://en.wikipedia.org/wiki/M...

The first book was set mainly on Mars. The creatures there were essentially innocent with regard to sin. It is an interesting take on the idea of the uniqueness of Christ's sacrifice. There may be only one world, ours that needed such remedial treatment in Lewis' view.

Natural gas does not seem to do all that well below $3/MMBTU so utilities will have to find less costly generation and lower prices if they want to retain their market share. Wind, and soon solar, could pin natural gas down to $3/MMBTU and start to cut its share, so utilities should be looking at these forms of generation to avoid losing custom to DIY.

Isn't that just shifting the depreciation advantage with the hardware?

Here is the transcript of President Obama's speech on climate at the UN: http://insideclimatenews.org/b... I think this is the anchor paragraph:

"So today, I call on all major economies to do the same [declare emissions targets and implementation policies]. For I believe, in the words of Dr. King, that there is such a thing as being too late. And for the sake of future generations, our generation must move toward a global compact to confront a changing climate while we still can."

Threatening China with Dr. King may be even more potent than moving to impose carbon tariffs on their imports. http://news.slashdot.org/story... The legitimacy of China's government is threatened by Dr. King's philosophy.
