Thank you, I prefer up to 6 °C of warming.
Coool pictures: A waterfall or, more precisely, an ice-doesn't-fall-because-it-is frozen, and three more recent freezing pictures...The article indirectly indicates that the oil produced in this way could cost as little as USD 40 per barrel or less. That's pretty good now when the oil price is above USD 100, 25% above the USD 80 price first reached in September 2007.
In 2004, we also talked about the USD 15 per barrel oil produced from things like turkey guts ;-) but I don't know what happened with this particular technology. On the other hand, I can tell you that the German biodiesel industry has finally collapsed. Thanks Gott. ;-)
