the amount of melting left to do after the last glaciation is tiny, so I don't think fresh water is going to stop the Gulf Stream.

I don't know about that, Mq., since there could have been some sort of stasis achieved which is being fiddled with by the increasing amount of excess fresh water.

I wish I could put my fingers on it, but there was an interesting report recently concerning the fact that there is a certain organism on which certain fish feed which develop only at the deep end of the North Atlantic Ocean--some Pass or Canyon or something, I can't recall--under certain specific salinity conditions. The fish were disappearing which prompted some clever scientist to look at causes for the demise of their food. Turned out that the organism was disappearing because the specific salinity conditions under which it thrives were being altered in favor of fresher water, leading the clever scientist to think that the conveyor is being damaged now.

I probably got a bunch of the facts wrong, but I assure you the gist of things is right on the money.

I don't personally feel that the conveyor is going away tomorrow as it's going to take a lot of fresh water in excess of what has been normally melting to affect the salinity of a water flow equal to 100 Amazon Rivers. But we really don't know enough about hydrodynamics and the stasis point of the conveyor to say with any degree of accuracy that it won't happen in the next 10 to 15 years. It might, and we're simply not planning for it.

Heck, we could start by pouring a lot of salt on the melting stuff. Salt is cheap. I don't know why I haven't seen any reports on such a simple solution.

If not prevented, the effects will be disastrous for most of Europe. Excess co2 will be partly the culprit along with a lot of other things, though I personally feel excess co2 will be found to be the most significant cause.

There is not much that we can do about excess co2 except, like you, learn to enjoy it. I hope you are correct. I have no certainty in this field, it's much to complex for me to understand.
