This is very bad news, except maybe for Chinese extreme outdoor down clothing factories. London is at the same latitude as southern Hudson’s Bay; Rome and Madrid are about as far north as New York. Without the Gulf Stream pumped-hot-water heating system, Europe would be a very different place. The world may be getting warmer generally, but if (a fair number of scientists are starting to say when) the Atlantic circulation stops, some important parts of it will go the other way, and dramatically so. Just to offer one example, all of France could easily find itself above the practical limit of cultivation of Vitis vinifera, the wine grape.
Of course the habitability of a small continent isn’t something we should have to bear any economic cost to prevent, certainly we wouldn’t betray our most fundamental national principles of big houses and cars for a bunch of foreigners. Anyway, they’ve been taking all that heat right from Florida for centuries and not paying us a cent for it. Defeatist talk about a carbon tax just encourages…encourages somebody bad, certainly, I’m sure it’s treasonous.
But you might want to take your kids to Europe sooner rather than later to be sure they don’t miss it.
