The Status of Ireland’s Climate Report August 2021

The Environmental Protection Agency (EPA), Met Éireann (MÉ) and the Marine Institute (MI) have published a report on “The Status of Ireland’s Climate”.  It confirms and updates findings from the 2012 report and details how global changes are being reflected in our atmosphere, oceans and our landscape.  For the key findings click here.

Key findings from the Status of Ireland’s Climate Report

Atmosphere

  • The annual average surface air temperature in Ireland has increased by over 0.9oC over the last 120 years, with a rise in temperature being observed in all seasons.
  • Annual precipitation was 6 per cent higher in the period 1989 to 2018, compared to the 30-year period 1961 to 1990.
  • The concentration of the main Climate driver: greenhouse gases - carbon dioxide, methane and nitrous oxide - measured in Ireland, continued to increase since 2012 with long term implications for our climate.

Oceans

  • Satellite observations indicate that the sea level around Ireland has risen by approximately 2-3mm per year since the early 1990s.
    Measurements in the surface water to the west of Ireland indicate an increase in ocean acidity which is comparable to the rate of change in oceans around the world.
    The average sea surface temperature measured at Malin Head has been 0.47ºC higher over the last ten years compared to the period 1981-2010.

Land

  • There is an increase in river flows across most of Ireland since the early 70s. However, there is evidence in recent years of an increase in potential drought conditions especially in the east.
  • Land cover observations since 1990 show increases in the areas covered by artificial surfaces and forest whilst there is a decrease in wetland areas.
