>>Break down in the North Atlantic drift<< you mean North Atlantic conveyor () ... Looks like - from what I remember to have read - this kind of changes are more of a switch on/off kind (iow catastrophic). If Gulf stream turns off, then it's not just Scandinavia and Russia, it's also US (no more tornadoes?) DJ I dont think the term is really conveyor - I have it at the tip of my keyboard; - it's the deep-sea twin of the Gulf stream.

Suppose you look to Earth's pole from space. Over time you would see that axis wobbles and draws a number 8 shape. It is this movement that starts and ends glaciations. This is the big thing. But in the interim period, the Sun, volcanic eruptions and other phenomena distorts the temperature pattern. Now if you look to the curve of temperature, you see an up tick. We are now alive during this up tick that why we are seeing it raising. Perhaps there have been an even bigger up tick, the one that make the masthodons with belly full of grass found in Siberia deep forzen.

Hi David, For a decade - heck, now since 1986 - I've been a promoter of CO2. I think we are doing a great job of avoiding any more of that nasty ice-age stuff which buries the land masses in the northern hemisphere under kilometres of ice, which is undesirable [for humans anyway]. There aren't many land masses in the southern hemisphere, but it does get too cold down here in ice-ages. The land in northern Europe is still bouncing back up after the last, crushing, eons-long burden of frozen wasteland. As you pointed out, much of the carbon is locked up in limestone, so we need to figure out a way of freeing that up. I think the best way is to make it into concrete. Huge concrete highways could be built across all land masses. That would be economically great, as well as producing huge amounts of CO2 from fuel to heat the limestone to make the cement and from the CO2 driven off the limestone in the process. Vast coal fields could be dug up to fire the kilns. Once we had umpty million kilometres of road, that would also increase the reflection of sunlight. We might like to overlay it with asphalt to make a smoother surface [concrete seems to always be too rough, though that's probably just careless workmanship] and darken it up to absorb more sunlight to maintain heat. More benefits would come from planting Australia in a mixture of crops and photovoltaics, changing the climate to Brazilian jungle. With Iraqi oil back on the market, we should be able to boost consumption because the price will be lower with a lot of the stuff for sale. That will accelerate CO2 production, which is great for plants, which just love eating CO2 and like it warm [check out the tropical jungles for how warm they like it] to keep their chemical processes zipping along. The earth has been gradually dying for eons as the oceanic crust conveyor belts and sedimentary processes have carried marine sediments into permanent cemeteries. It is only thanks to our presence and energetic quarrying that life is burgeoning again. Umpty petatrillions of lives have been unlived because of their essential carbon being buried in the earth, dead and sealed. Only a little has been recycled in volcanoes and by erosion of limestone, coal and other carbonaceous deposits. The life-force of Earth has been gradually depleting. Thanks to us, our SUVs and 777s, we are bringing it back to full-blown exuberance. With our incipient genetic engineering talents and quantum computing design modules, we'll be able to make an infinite array of species, each controlled with a solid-state device linked back to the cyberspace It which will manage the whole show, keeping it in balance and avoiding any untoward runaway processes. Any species which gets out of hand could be genetically switched off. With the modelling power we'll be able to bring to bear, that'll be unlikely, but just in case, it's better to be safe than sorry. Just some thoughts for the day, Mqurice
