Can someone please provide a source to the claim that the Eastern seaboard will be colder in global warming in the winter while the rest of the world warms up?
I thought that Scotland/Ireland would get colder because the Gulf Stream would shutdown?
Eastern USA should give some of its cold to the western states to balance things out, really. The cold in North America is way too slanted and unequally spread.

Tom77falcons posted an article about it, but the colder temps of the Eastern US will only be temporary, as initially, the warming causes arctic destabilization that leads to the jet-stream dip cold spells. But as the warming continues, the arctic just won't have cold anymore, and the Eastern US will then moderate significantly.
It's like a ship sinking at sea, but first, one end rises up.

This is entirely possible. Having no particular knowledge, I am however tempted to speculate.... At the conclusion of the previous ice-age, was it not the case, that as the North American ice-sheets retreated, and global ocean-levels rose, that the Gulf Stream was disrupted? That made Western Europe significantly colder - for (I gather) centuries, if not longer. This may have been a fluke, or a pattern. The possibility therefore exists, that these jet-stream dips and associated bouts of severe cold in the eastern US, may become a long-term event, on the scale of a human lifetime.

Any experts who care to chime in on this?
Well if you look at another significant event, the changing of the Sahara Desert from a green humid area to a desert took around 100 years. And during the green period it was back and forth:
"A curious discovery from the marine sediments is that the transitions into and out of the wet period occurred within decades, not the previously-thought extended periods."
I believe that there may be a decades long drought in California, like was was recently experienced. Some believe California is still in a drought and the respite last year was just a variability.
So with the dipole situation I believe that it's possible to have a decade or so of these extreme winters, interspersed with milder winters. During those milder winters on the East Coast, CA will have a lot more rain and cooler temps as the trough will be out West then.
Then I speculate after around 100 years these spells will stop happening altogether and you'll see a drastic warming of North America.
Wait, first off the eastern 2/3rds are warming during the winter, not cooling. Just because we have bouts of cold (always have) doesn't mean it is a result of man made climate change. What exactly is the difference between the bouts of cold now and the bouts of cold during the 1970's and 80s'?
If anything, it's our summers and autumns that are seeing the least warming (at least over Illinois).
In fact winter is the fastest warming season from 3/4ths of the country (especially the eastern portion)

The warming around the world is not equal. Eastern North America lags. wait till after another 10 years of these winters. They will become more common and winter averages will drop.
