    Firstly moderators not sure where to post this question so please do what you want with it.
    It possibly a little childish of a question but interested to hear your thoughts and reasonings.Thanks.

    My question is what would the lowest temperature possible Ireland could have got to ever, this includes the last Ice age.

    Second part

    Whats the lowest temperature Ireland could ever get to now? -19 I believe has been recorded in Sligo. Is it conceivable we could get into the -20s In winters to come?

    If the Gulf Stream slows down, then below -19°C is possible. The Gulf Stream helps keep Europe ice-free throughout the Winter.

    Ice age temperatures could have been a lot lower since much of Ireland and Britain were covered with ice and sea level dropped considerably with the northern parts of the Atlantic frozen over. Something like -30 C would not be an unreasonable guess. Even -35 C is possible.

    Ireland has the lowest "highest ever temperature" of any European country and the highest "Lowest ever temperature" also! Interesting fact

    I thought Iceland beat us on that. I think we have the second lowest highest temperature ever recorded worldwide.

    Ah icelands not in Europe ;) but your right, their highest ever temp was 31 or something...

    And also strange is the fact that the most northerly point in Ireland is in the South.

    Yes, it is:

    Took me a second to figure this out.

    Non-politically, the most westerly point of Ireland is in the south while the most easterly point is in the north.

    That actually hurt me to figure out

    If the Gulf Stream slows down, then below -19°C is possible. The Gulf Stream helps keep Europe ice-free throughout the Winter.

    Dublin sits at 53 degrees North, same as Edmonton in Canada which has got as low as -49c and parts of southern Alaska.

    So yes if Gulf Stream did slow we would have extremely cold winters here.

    realistically speaking, what are the chances of the jetstream slowing down / what would actually cause it to slow down?

    Gulf stream or jet stream?

    If Gulf stream, as far as I am aware, there is evidence it is slowing down. Increased melt waters from arctic and Greenland glaciers will slow it down and dilute/reduce salinity of the ocean.

    Perhaps the only real chance within the next 50/100yrs or so would be in the event of WW3.

    i.e. If just a portion of the two superpowers stockpile went hot, the earth would go quickly into a cool nuc-winter. Whereby global tempurates could drop by 10oC.

    A {super}volanic eruption might do something slightly similar, but there hasn't been one of those for a fair while. A large asteriod landing would also mean an extra coat or two for the winter.

    I'm pretty sure it dropped below -20C in places like Baltinglass during the Dec 2010 cold spell. Similar temps recorded in Ballinrobe down West during the Dec 2001 cold spell

    Incorrect, its the prevailing westerly. If we had constant easterly winds from November to March, our winters would be much more severe. In fact, during the 2010 freeze, the liffey started to freeze over during the final days of that spell. Another week or two and I'd say Dublin bay would start to freeze.

    But if there was no gulf stream, would the westerly winds not be much colder than at present, due to the fact that the ocean at our latitude would be a lot colder?
