| 593703 | 2007-10-22 00:09:00 | Thank you Digby - the only sensible reply. Of course climate change is not the fault of man - don't be silly! That is such an arrogant stance! What makes you think firstly, that we can in any way match nature (with the amount of CO2 that we produce) and secondly that we are able to stop it? The earth has been warming since the last mini ice age about 700 years ago and, eventually, it will cool again as it has been doing for quite a few million years. The White Cliffs of Dover, for example, are composed of tiny deceased organisms, which is quite remarkable considering the size of the cliffs, but it is even more remarkable when you realise how much carbon they cumulatively sequester. A 6 inch cube of Dover chalk will contain well over a thousand litres of compressed carbon dioxide that would otherwise be doing us no good at all. Altogether there is about twenty thousand times as much carbon locked away in the earth's rocks as the atmosphere. Eventually much of that limestone will end up feeding volcanoes and the carbon will return to the atmosphere and fall to earth in rain, which is why the whole process is called the long-term carbon cycle. The process takes a very long time - about half a million years for a typical carbon atom - but in the absence of any other disturbance it works remarkably well at keeping the climate stable. Unfortunately, humans have a careless prediliction for disrupting this cycle by putting lots of extra carbon into the atmosphere. Since 1850 it has been estimated we have lofted about 100 billion tonnes of extra carbon into the air, a total that increases by about 7 billion tonnes a year. Overall, that's not all that much. Nature - mostly through the belching of volcanoes and the decay of plants - sends about 200 billion tonnes into the atmosphere each year, nearly 30 times as much as we do with our cars and factories. But you only have to look over any major city to see what a difference our contribution makes. So as you can see, we are not causing global warming (although we are contributing to a small degree) and it is arrogance in the extreme to think that we can influence that change in the slightest degree, even if we stopped ALL our contributions right now. If you need any proof that all this has happened before, you need go no further than Franz Josef Glacier. At present you will hear the doomsayers telling us how Franz Josef is receeding -as are other glaciers in the world. But if you have visited Franz Josef, you will have seen at the information centre how the glacier has advanced and retreated over the last 150 years, so it is nothing new. As with so many other topics, we are being fed some truth but not all the truth and TONNES of mis-information. Source of the above material is "A Short History of Nearly Everything" by Bill Bryson. It is a MUST READ for anyone with the slightest interest in what has and is happening to our world today. Not only has it truckloads of information, but it is a travelogue of science with witty, engaging and a well informed guide who loves his patch and is desperate to share his delights and humour with us. I recommend the book to everyone. Roscoe. |

| 593704 | 2007-10-22 00:13:00 | We are having an early start of winter. Can I say “We are having Global Cooling”? One guy wrote a book about global warming and is getting richer for it. What I was getting at about the thermometer. Did they place it near the freezer, engine room? How can they compare these ancient temperature reading to modern digital thermometers readings? I want to see proof that the oceans are warming. I know the land is warming (slightly) because of all the tree cutting. Instead of them raking leaves, they just cut the tree down and then go to a “green’ meeting. I should write a book about using white asphalt, that would work if you want cool. d they have many different ways of finding historical temperatures, one of which is ice core data (which also gives information about past co2 levels). a thermometer attached to the outside of the hull would not be influenced much by the slight temperature difference of the hull and many people stand to lose money due to global warming. so one could say the anti warming crew are in it for the money also. Ok if the sea level rises no biggy, anyone heard of sea walls.? omg:groan: worked really well for new orleans didn't it? one storm and the whole place went under. then there's that wall/gate/dam thing london has in the thames. the thing is being used many times more often than when it started because sea surges are becoming all too common and is due to reach the end of it's service life early as a result do you mean to suggest we build big walls around all coastal settlements, like inverted fish bowls? |

| 593705 | 2007-10-22 00:44:00 | Sorry, Global warming is a fact. I have carefully monitored the outside temperatures all day today, and if the trend so clearly shown here this morning continues for just one week; we are in for change. It was 10.5 deg at 5:15am. It is 17.7 deg now (9:13am.) All temperature measured with an iMometer, and calculations processed on an iBacus with corrections for daylight saving freely applied. Measured rise is 7.2deg C in 3 hr 58 min. Rate of increase, 7.2 deg / (3:58 hr., or 238 min.) or, + 0.03052 deg/minute or 1.81513 deg/hour. At this rate, it is expected that the temperature on my front porch will reach 100 deg celsius in (100-17.7) / 1.181513 = 69.66 hours, that is 69:40 /h:m, or 2.9 days. With due allowance for the fact that today is Labour Day, I fear that on Thursday at, approximately 8 o-clock in the morning the temperature will be such that I can sell my electric jug, and make coffee by leaving the cup on the doorstep. This is quite a saving in electrical energy and added to the fact I will no longer have to buy snail pellets, my savings can be enhanced. These savings will enable me to buy a bigger, more powerful refrigerator to make ice cream which I anticipate will find a ready market. Everything appears to be tip-top at this point. |

Be careful! do you guys get tiptop icecream over there? i know we export to japan at great expense (they actually pay ridiculous prices for refridgerated shipping as we actually have cream in our ice cream) |

| 593709 | 2007-10-22 01:42:00 | OIC...no..we get a product called "Blue Bunny (www.bluebunny.com)" which is very good...and real cream/sugar and ingredients. Then there's Denali (http://www.moosetracks.com/)...another very good ice cream. |
