    The Pentagon sees climate change as "an immediate threat."

    Pentagon: Climate Change Poses ‘Immediate Risks' | Climate Central

    It is my belief that this is a blatant attempt to get more military funding. Part of the plot would likely be to erect a great number of wind turbines for the air force to practise manoevres and prepare for close combat with ....... (name the enemy) by flying around them.

    Val is not entirely wrong in his conspiracy theories of wind power advocates. Is he?

    September 2014 temperature anomaly (difference from average) from GISS.


    Warmest September in the record.

    It seems that part of Antarctica are ~8C above the norm.

    2014 will be one of the warmest years ever.


    September Was Warmest on Record, NASA Data Shows | Climate Central

    So far, this decade (almost 5 years old, now) is warmer than the last one.

    That must be the reason there's so much sea ice

    Question - how is the 'warmth of the year' calculated ?
    is is the average of measurements of air temperature from thousands of meteorological stations, all over the planet ?

    as a keen gardener, i would agree that temperature in Ireland (notwithstanding some poor Summers) appears to have increased over the years.
    St Patrick's Day used be the traditional date for pruning roses.
    it is far too late nowadays.

    You might find this interesting.

    Flowers blooming earlier now than any time in last 250 years

    Finding the average of a quantity over the surface of a sphere from thousands of temperature stations scattered non-uniformly over the earth is a non-trivial task.

    As simply as possible, the surface of the planet is divided into rectangles of equal area ("gridboxes") and the average temperature of each rectangle is estimated from a selection of temperature stations within each rectangle. Those are then averaged over the surface of the earth.

    Of course there are rectangles where there are none or few temperature stations (the Arctic, the ocean), and others where there are a lot (e.g. UK), so to get the detail look up the NOAA or UK Met Office sites.

    Another method is not quite at the surface, but Lower Troposphere Atmospheric Temperature taken by microwave sensors on satellites. That is done by NASA at the University of Huntsville (UAH), Alabama and by a private contractor known as RSS. Satellites have problems with the top and bottom of the planet as well, so strangely no organisation has complete coverage over the Earth.

    Mathematical methods are used to fill in gaps.

    There are many organisations measuring global temperatures and here you can look at their results:

    CRUTEM4 temperature data Google Earth interface

    Berkeley Earth - Google Maps Gallery

    This is the temperature since 1750 for a point on the island of Ireland by Berkeley Earth:

    Antarctic Sea ice is increasing at the edge of the sea-ice pack, miles away from shore, very little to do with the land temperatures in Antarctica, but a lot to do with oceanic winds & atmospheric effects like the ozone hole.

    As you know (or do you deny it?) Antarctic land-ice is diminishing.

    Here is a temperature set from a place not far from the South Pole, from the Hadley Centre:


    The link is in the post above.

    So we after some gyrations up and down and sideways, we are now, at <9 degrees, somewha below the temperatures prevailing in the late 18th and early 19th centuries.

    Is this supposed to induce Climate Alarm Panic?? If so, I am completely unmoved.

    Have you cleaned your glasses recently?
