| 833752 | 2009-11-29 23:15:00 | Well it's happened before so why not again?? You're really not thinking are you? Yes it's happened - but humans weren't there!!! The ice reflects heat that would have been absorbed by the ocean at the poles. Absence of these ice will warm the ocean greatly and will truly cause global warming. With all the ice melted, the Pacific Islands and many other inhabited low countries will drown, creating a surge of probably political, economical and social strains as all many millions of people become refugees. Without the ice the thermohaline circulation of the ocean, which distributes energy around the ocean, will cease and while the affects of that I do not know if all the ice has melted, it's probably going to be hell on top of super hell. |

| 833753 | 2009-11-30 03:39:00 | I posted this years ago on another site and also here I believe, here it is again: Actually, a simple model of what is going on is this. We are in a system with negative feedback applied, as the system is disrupted by internal or external forces the feedback loop acts to hold the system in stability, the bigger the changes the bigger the fluctuations within the control loop which normally have a sine wave shape. As the stability of the system is tested in our case by more energy in the system ie global warming, as the feedback loop loses control the sine wave shape will tend to become a square wave as the limits of control are reached. In this case the world's weather is kept in some form of stability by the sharing of the heat at the Equator with the cold at the poles and vice-versa. See: Gulf Stream and Atlantic Conveyor - our feedback loop. The melting of the North Pole (fact) is allowing more fresh water into the North Atlantic which is disrupting the process in ways not fully understood as yet. As this system is disrupted by whatever, we would expect to see more energy at the equator ie more hurricanes and less energy at the poles ie colder Winters on average. The predictions are that there will be wilder weather for a while as the Global warming is exacerbated by our activities then as the feedback loop loses control completely we will go into an ice age for a few thousand years in as little time as 100 years as has happened many times before in the history of the earth. Think of a bi-state circuit which temporarily is maintained as a sine wave oscillator by feedback but has now flopped into one or other of the two states possible for a while to get a more accurate picture, I think. FWIW |

| 833754 | 2009-11-30 04:47:00 | I disagree. :) I think it resembles more closely an asymmetrical free running flip flop. However, be it sinusoidal or asymmetrical, taxing it won’t fix it. ;) |

| 833755 | 2009-11-30 07:19:00 | Sine waves are everywhere in nature, look at tidal changes for instance, gradual repeating change over a period in time (in continuous cycles) is what equitable climate is all about. When it is flip flopping (square waves) it won't do it many times before it locks into one of the extreme states, ie ice age round the poles and overheating at the Equator. This has happened a number of times before, it's in the geological records, if we succeed in precipitating an new ice age we won't go out of it for longer than civilization has existed. The danger is in taking the analogy too far B.M. but I certainly don't think a square wave generator fits the bill even with pulse width variation except in the last stages when it is game over, remember with a flip flop if it was not limited by power supply rails you would have transitions between minus and plus infinity with a very high slew (tending to infinite rate of change at cross-over) rate and under normal conditions on Earth we clearly do not have that, so I really don't know what you mean. |

| 833756 | 2009-11-30 18:22:00 | Yes I would like to know how "they" hanged it from "Global Warming" to "Climate Change" so quickly and got every one to buy into it and call it "Climate Change". If the world is not still warming, why did they change the term to Climate Change? Several things worry me and I have only one answer. The seas do not appear to be rising - sure there is coastal erosion (there awlays ahs been) The polar ice does seem to be receding The icecaps on many mountains ranges does seem to be receding. The world temperatures do not seem to be rising (indeed for the last few years they have fallen. Putting taxes and carbon credits just share the carbon produced around the world, they do not reduce it. The worlds growing population and growing development can only mean the use of production of more carbon. The only real way of reducing our production of carbon (if that is the problem) is to start reducing the worlds population - right now by bringing in a one child per woman policy (then compulsory sterilization) for say fifty years. Or by banning sales of new cars, tv's, phones etc. |

The islanders can build sea walls and stay put no one likes quitters. |
