    Well, who knows maybe it'll slow down, the north pole will freeze up again and everything will go back to normal. I fucking hope so.

    The possibility of the freezing of the UK and Europe will be determined by a "tug-of-war" of sorts, between the amount of greenhouse gases and the speed with which the MOC slows down. Greenhouse gases may have more of an impact than a slowing of the MOC, simply because they are more abundant today than ever in the earth's record. (CO2 levels were at 380 ppm as of 2007, and were never above 300 ppm during the 400,000 years studied in Antarctic ice cores).
    Ocean experts see the MOC as having three levels: "faster", "slower", or "off." A 2005 comparison of eleven climate models showed that the MOC will likely be slowed by 10-50%, however, because the levels of carbon dioxide are so elevated, any cooling produced by the MOC slowing would be modest because the greenhouse gases would more than compensate. As a result, a net warming is still shown by these models for the UK and surrounding countries. Improving our measurements to monitor the MOC will allow for better predictions and reduce uncertainty of the amount of warming or cooling these areas of northern Europe will encounter.

    I'll just emigrate. ;)

    Rick Wakeman was on telly last night, and he very summed up this years summer as follows:

    "Autumn with green leaves."

    Kind of rings true doesn't it.

    I hope next year is better, I'm going to go to a tanning salon through this winter to try and get some vitamin D...

    It gets surprisingly cold here... its just too effing humid. When its cold its WET cold, cold. It will be 60 and feel like 40 and wet. You just ran in the rain in 40 degree weather wet cold .The best part is it is that cold one day- and the next day it will be 90 again.

    Well, maybe I am indeed talking out of my ass, or maybe the BBC that well renowned for it's accurate news coverage is also.

    http://news.bbc.co.uk/2/hi/science/nature/7585645.stm

    "Arctic sea ice has shrunk to the second smallest extent since satellite records began, US scientists have revealed.
    The National Snow and Ice Data Center (NSIDC) says that the ice-covered area has fallen below its 2005 level, which was the second lowest on record.
    Melting has occurred earlier in the year than usual, meaning that the iced area could become even smaller than last September, the lowest recorded.
    Researchers say the Arctic is now at a climatic "tipping point"."

    "Most of the cover consists of relatively thin ice that formed within a single winter and melts more easily than ice that accumulated over many years.
    "

    The fact that the ice sheet may well melt completly is something we can agree on.
    That is what your link is suggesting, right?
    That's not in dispute.

    It also mentions a thiner layer is increasing but the overall layer is decreasing.
    It seems to suggest the "ice-covered area" is shrinking.
    It seems to be suggesting larger areas remain open water rather than ice.

    You said it (layer of ice) would increase (but be thiner), right?
    On that point maybe you are talking out of your ass.
    Or to be fair (and a lot less patronising) it is unlikely that will occur.

    I hope the ski season starts early this year.

    Why? They say that 1. The ice shelf is thinner, and 2. Your quoted piece of graphical evidence says that the ice shelf is getting bigger, at least in area that looks to be the case.

    If you take an big chunk of ice floating in water, and melt it slightly, then refreeze it, would it not flatten and spread out?

    OK take a lump of ice sitting on a table, melt it a bit and then freeze it again. What happens? Maybe this is happening in reverse, the underside of the ice shelf is spreading out, and the air/sea is the table.

    how would the poles melting making it colder exactly?
    http://www.theregister.co.uk/2008/08/15/goddard_arctic_ice_mystery/
    Arctic ice refuses to melt as ordered

    Well, from basic thermodynamics-

    The North Pole is system 1 and the air surrounding it is system 2. When system 1 melts it's temperature increases, and that increase in temperature can only be accompanied by a decrease in temperature in system 2.

    Hold an ice cube in your hand and see what happens to your hand when the ice starts to melt.

    Like I said the area covered by a thiner area of ice could increase and seems to be increasing.
    But, and this is my main point, the overall area will not increase (imo).

    my hand would get wet, but ice melting doesn't indicate a drop in temperatures. but rather a rise in them.

    yes, my hand would get cold, but only because there would be a piece of ice in it. not because of an increase in temperatures. cold temps do NOT make ice melt.
