Use water bombers to drop all kinds of black matarial on top of the glaciers. Use nuclear weapons to open the Isthmus of Panama. (Ice ages are postulated to have started when North and South America joined.)

Climate change is fact. Greenland was green long ago and it was not by man doing and will be again. The only constant in this world is change. Love it or give up and die.

A lot of power, little atmospheric pollution. Btw, the new designs for nuclear reactors are completely safe. Not only have core reactors themselves gotten safer, but the plants are designed so that they will implode and contain radioactive contamination, not explode and spread radioactivity. Admitted problems...what do you do with the depleted end product? While the solutions right now aren't great, they are good enough til a more permanent one can be found. So stop being afraid of a vastly beneficial technology and start supporting nuclear power. Nuclear Power...'nuff said. A lot of power, little atmospheric pollution.

Earth is in Greenhouse saturation effect, the CO2 effect is small, But the Black Carbon is a real warmer.

Best start raising horses, because we're going to need them in the coming era of declining energy. Hydrogen fuel is a scam, as is biodiesel and ethanol.

Most recent was in 2007 when one they reduced the sulfer content in diesel fuel and are going to all but eliminate it in 2010. Two ALL new diesel engines have "deisel particulate filters" basicly a ceramic air filter and also after that a catalitic converter just like a car to remove ALL soot from going out the exhaust. Diesel engine oil also changed formulas for the new engines to be cleaner. For years and years fuel injection presures have increased and increased from about 500 psi to over 35000 psi for better atomization and burning of the diesel fuel. California police carry "smog cards" that they can look at a trucks exhaust and pull it over if it is polluting and have been doing this for years. I work at Peterbilt dealership. I see the canges to these engines every day. The EPA is getting stricter and stricter on them. The problem has been known and been being dealt with for a very long time.

In my opinion, the cleanest source of energy is solar power -- that uses energy that comes from the sun, not taking any energy from the Earth. all carbon is not black. diamonds, for example. that's all carbon (except for the small percentage of impurities that give them their various colors).
