***&@@!! Not what I want to hear first thing in the morning. The loss of the Gulf Stream would make where I live very much colder, and possibly uninhabitable. Grrrrrrrrr. |

Nah, Edwin. We will all find a way to cope - just look at the Innuit. Humans are adaptable; specialisation is for insects! I can't see it being pleasant though. |

We humans are the supreme spicies at adaptation that's why we can fly to the stars Just look at the places on earth we inhabit ,all the different environments.....from freezing cold to desert we adapt.....and overcome....... Take care all 😷😉 I |

Techno.... I know humans are wonderful at adapting if they are given enough time. I am not sure that a sudden flip in the mechanism driving the Gulf Stream would give us enough time to adapt. Having said that the community were I live now has between 800 and 900 people, but at its peak (late 1800s) there were over 2.000 people, so the area could probably support the current numbers at the start of an abrupt climate change, but we would all be living in poverty (as they were in the 1800 and most of the 1900s). For a sudden cooling we would have to live in the kitchen and the living room (next to the kitchen) and close off the rest of the house. A wood burning kitchen stove should keep the two rooms warm enough. Triple glazing and wooden walls with saw dust insulation are about the best that there is in keeping heat in, and of course south facing windows also help with passive heating. |

Late 1800s we were in the throes of a mini ice age. They had frost fairs on the Thammes and kept warm on the ice with bonfires! The "Dickensian" view of Christmas is based on the extra cold in that short period, which Dickens was all too familiar with. It rarely snows or even frosts deeply in London these days. Should the thermohaline current switch off, it would bring deep cold to both you and I, but even that would be temporary as worldwide temperatures are going up so fast. The climate is hugely complex and people forget that - assuming the thermohaline, gulf stream, ocean conveyor or whatever is the only heat transport. The jetstream also re-destributes heat around the planet and would take up much of the slack. There is local warming too. Trust me, I don't expect this to be at all pleasant! But one system cooling down while two warm up is unlikely to be too severe a change to survive - at least where heat is concerned. I would be far more worried about massive increases in wind. As the jetstream takes up said slack the whole planet warms even faster; as the ocean conveyor takes heat to us, it takes it from the South Pacific. The methane hydrates in many undersea areas and much permafrost are also beginning to melt/vaporise. Put those two together and overall warming should increase in speed. Before that carbon was sequestered by Mother Nature, chilly NE Scotland was tropical. Finland was equitable. Well the hotter the kettle, the more it rocks and sings on the stove; that is the currents of air and water speeding up inside. Technically, Britain does not get hurricanes. Well think again Limeys! the whole Northern hemisphere is about to be blasted repeatedly. As it gets warmer it gets windier. As it gets warmer it gets wetter - although a few poor sods get droughts. As it gets warmer sea levels rise. As it gets warmer you get more seismic activity (isostatic readjustment). Admittedly, we are in a warmer spot than you, but not by much and I am unworried. We are however building wind defences for all we are worth. We already moved up a hill and stored some supplies. |

The conveyor cycle starts in the north Atlantic where you have shallow/warm and deep/cold converging. The north Atlantic is the engine that runs the show for all the conveyors. If we lose that the entire conveyor system is completely fuxed up. Scientists can speculate, but none of them can say with any real certainty what will happen. Except bigger storms. Lots and lots of much bigger storms. |

I have read about a moraine ,that was left over from the last ice age, somewhere on the east coast of Canada/USA, About 10,000 years ago it broke sending it's contents into the gulf stream,plunging the earth into a mini ice age that lasted 1,000 years,it took about a year after moraine breaking for the ice age to start...... Will it happen who knows....????? Not to worry, just watch and be in awe of this wonderful planet...... Remember: "no-one gets out of this life alive"......(Clive James) Take care all 😷😉 |
