We think, as an economist who knows for a fact that two degrees increase in global temperature will be very good for trade and harvests and hungry people and trees and new species, that if these clowns could actually bring back global warming, they would be heroes. The governments of China and India might differ with that. AFIK, both countries are heavily dependent on irrigation water coming from melting snowpack in the Himalayas - which snowpack is diminishing as the globe warms. Likewise people in Persian Gulf states where an MIT study predicts major cities will become uninhabitable due to heat by 2100. -- Pete Cresswell Pete - where do you come from? China and India's farming and most of their water needs are supplied like most other places on this Earth - from RAIN building a water table and not from run-off from a snowpack. Pete is quite right. But it's not just Asia - large areas of the western US are highly dependent on melting snow. Rain is important too - I'm not claiming that snow supplies all water - but without the snow serious problems develop. This affects water supplies directly - and also fish runs (wildlife) and hydro-power and recreation. Reservoirs are nowhere near big enough to replace the water storage in snow packs. For example, there have been some recent slightly-warmer-than-normal winters in my state (Washington), where there's been plenty of winter-time precipitation, but there's insufficient storage from the flooding rivers. By mid summer -- farmers, cities, electric power companies, fishers -- everyone fights over the dwindling supply. Geography and ecosystems being what they are, increasing reservoir volume can't replace the enormous storage historically provided by snowpacks. And it doesn't help that the population in drier areas has been growing. This doesn't begin to touch on the increased evaporation rates from higher temperatures. Nor political struggles fighting over shared water resources. |

C shold be cast out for overbearing. Show us ... disingenuous statements of false logic .... annoying BS.
I produce primary field data on clean energy at the cutting edge of technology. Entertaining but needs restraint. Andy, it's raining at Yuma ! The home screen opened with rain dripping on the other side on 12/15 with The Plumber running at 10:50 est. Too much. |

Show us the calculation of the energy present in two one cubic meter volumes of water with a 7 degree differential temperature. Hell, you aren't going to do that. Well it's about the same value as a gallon and a half of gasoline. Thermal conversions of very low temperature differentials are notoriously inefficient and the actual recovery would be probably around 2%. Or about three hundreds of a gallon recovery in actual energy. If you were going to drive your car 25 miles how much gas would it consume at 55 mph? Divide that by 0.03 and multiply that by 2 cubic meters. |

Well EVEN if they continued as they are more land is being made than is being lost.
Where is this land being made? I know China is making some islands in the South China Sea to set up airports, docks to militarize the area. But I am not sure that counts. |

A whoa high point of this trip was arriving at Yellowstone Norris Junction Camp finding the hot springs then blowing a huge white vapor column skyward to a level where the go people flew down in a helicopter for a long looks on WTH was going on in there.
In keeping with the Fed crit, that was the last day for camping at Norris |
