2016 the Hottest Year Ever ?

In Ireland, 2016 was not the hottest year ever. Not by a long shot. As readers of this blog will know by now, Valentia is a very reliable record as it's among the oldest there is and is not tainted by the urban heat effect. Even Phoenix Park in Dublin City, which does suffer from the urban heat bias, doesn't show any record breaking heat. 


  1. In regard to the graph, I can remember in Ireland back to 1963, it was very cold, I remember the snow was up to the tops of my wellington boots and it was a white Christmas and lasted a long time. I also remember that 1976 was a very warm year with an Indian summer. Then 2007 was very hot. The summer of 1985 was very cold. Winter of 2009 and 2010 was the coldest in living memory. Before my time, 1946 and 1947 were very cold as was last year. So reports of 2016 being the warmest yet are lies and propaganda. The Irish broadcaster RTE has been reporting that each month and each year was the hottest yet, but still there is no cumulative cooling. Cold winters take a terrible toll on old people in Ireland and the UK.

    There is massive importation of coal from Northern Ireland into the republic where carbon taxes and VAT are lower in Northern Ireland whose senior citizens get a 300 pound sterling winter fuel allowance. Not in the republic. The graph is therefore correct

  2. Examination of the graph shows that for the past century (1917 to 2016) the mean air temperature for the Phoenix Park ranges between 8.5°C and 10.5°C with most values within +/-0.5°C of the mean of 9.5°C. Outliers are the cold years of 1917, 1919 and 1986 which tip the 8.5°C mark, and 1945, 1949, 1959, 1989, 1995, 1997, 2002, 2006 and 2012 which reach 10.5°C.
    However the outliers are just that; there are few mean values below 9.0°C and curiously, the last few years appear to be lower than the peak outliers despite media reports of "the hottest year". It would be interesting to apply regression analysis to the actual values to determine the trend over the logged period.
