I believe this has already been adressed and used as one of the proving points for the oceanic conveyor belt theory which says, that most of the world's temperatures are regulated by deep sea currents which distribute temperature evenly across the globe [water being the perfect temperature storer, a fact used in many eco houses]. These currents are most affected by 1) temperature of the water itself and 2) salt level. The lower the salt value the slower the coveyor goes.
Now, when temperatures grow, the ice caps begin to slowly melt, dilluting the areas where the conveyor is most sensitive and causing it to slow down, which has the result of temperature redistribution slowing/stopping. Thus, as in the case of WayBack[tm], we get areas of higher temperatures and, when it comes to the Little Ice Age, areas that depend on oceanic regulation [like the British isles] where we get low temperatures.
The problem with global warming is not that "it will be warmer" but that if/when the conveyor stops, all hell breaks loose. As past records indicate, when there are no more regulating safeties in place [as the ocean grows warmer, the plankton chiefly responsible for absorbing the atmospheric CO2 and storing it at the bottom of the ocean in shape of their endoskeletons is replaced by another kind that is better suited for warmer temperatures... But stores CO2 a lot worse, plus actually releases some of the CO2 back in gasseous form during their life cycle] temperatures begin to jump wildly, high one year, low another, which has the effect of killing off all the flora and fauna that cannot adapt to the rapid changes. Ice-core research has proved that had happened in the past and it could happen again.
Also, I believe that "highest temperatures ever" claim was made about the last 100 years, not the last 1000.
I have not seen the "effects on the conveyor belt" in peer-reviewed papers, but I'm certainly interested.
Historically--as in BIG history--we are about in the middle, currently. But if things keep up at the most severe predicted rate for a hundred years--we will still be about in the middle.
