Ireland's Climate Observation System: an update - Ned Dwyer, UCC Ireland's Climate Observation System: an update - Ned Dwyer, UCC Presentation Transcript

  • Ireland’s Climate Observation System An Update Ned DwyerInforming & Enabling a Climate Resilient Ireland
  • Why are climate observations needed ?• Characterize state and variability• Determine natural and human contributions• Help determine causes of change• Support prediction of change• Understand regional and local effects• Characterize extreme events Informing & Enabling a Climate Resilient Ireland
  • Use of Climate Data Agriculture Biodiversity Industry Coastal & Marine Energy Fisheries Informing & Enabling a Climate Resilient Ireland
  • Use of Climate Data Agriculture Biodiversity Industry Coastal & Marine Energy Fisheries Forestry Health Peatlands Spatial Planning Tourism Water Management Informing & Enabling a Climate Resilient Ireland
  • Use of Climate Data – in more detail Water Management•Plan and manage for a sustainable water supply,both surface and ground waters•Manage for competing demand e.g. agriculture,industrial, drinking, recreation•Identify resources at risk from soil and peat erosion, landslidesand the spread of agricultural pollutants Informing & Enabling a Climate Resilient Ireland
  • Elements of a Climate Observation System Informing & Enabling a Climate Resilient Ireland
  • The Essential Climate VariablesAs defined by the Global Climate Observing System Informing & Enabling a Climate Resilient Ireland
  • Climate Status – Air Temperature Mean Temperature Anomaly (1900-2010) - Difference from 1961-1990 Normal for 5 long term stations - 11 year Moving Average 1.5 1 Temp. Anomaly ( C) o 0.5 0 -0.5 -1 1900 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Year Data courtesy: Met Éireann T mean approximately 0.7o C higher than the long term 1961-1990 normal Informing & Enabling a Climate Resilient Ireland
  • Climate Status – CO2 Concentrations Carbon Dioxide (CO2) 1958 - 2011 monthly mean concentration Mauna Loa (Hawaii) Mace Head 400 390 CO2 concentration (ppm) 380 370 360 350 340 330 320 310 300 1955 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 2010 Year Data courtesy: LSCE, NOAA/ESRL, NUI-G concentrations currently > 390 ppm and still rising Informing & Enabling a Climate Resilient Ireland
  • Climate Status – Sea Temperature Sea Surface Temperature Anomaly (1958-2006) (relative to 1961-1990 mean) Malin Head (coastal SST) AVHRR (45 - 60 N; 3-20 W) 1.5 SST Anomaly (oC) 1.25 1 0.75 0.5 0.25 0 -0.25 -0.5 1955 1965 1975 1985 1995 2005 Year Data courtesy: Marine Institute SST increased at a rate of 0.6o C per decade since 1994: This is unprecedented in the 150 year observational record Informing & Enabling a Climate Resilient Ireland
  • Climate Status – Above Ground Biomass Modelled Forest Carbon Stock 1990-2009 23000 22000 Forest Carbon Stock (Gg) 21000 20000 19000 18000 17000 16000 15000 1990 1993 1996 1999 2002 2005 2008 Year Data courtesy: EPA Forest carbon stock has increased by 40% since 1990 Informing & Enabling a Climate Resilient Ireland

  • Status of Observations - Atmosphere Yes Partial No Informing & Enabling a Climate Resilient Ireland
  • Status of Observations - Oceans Yes Partial No Informing & Enabling a Climate Resilient Ireland
  • Status of Observations - Oceans Yes Partial No Informing & Enabling a Climate Resilient Ireland
  • Status of Observations - Terrestrial Yes Partial No Informing & Enabling a Climate Resilient Ireland
  • Status of Observations - Terrestrial Yes Partial No Informing & Enabling a Climate Resilient Ireland
  • Some key conclusions• Existing systematic observation programmes must be maintained and those funded on an ad hoc basis (e.g. atmospheric concentrations, oceanic) should be secured• Additional resources required in a number of areas (e.g oceanacidity monitoring, data homogenisation and analyses)•Appropriate long-term climate observation sites should be identifiedfor variables monitored under other programmes (e.g. river flows andlake levels as part of the Water Framework Directive; sea state forocean weather forecasting)• Need for co-ordination between different bodies carrying out climatemonitoring to avoid duplication and to maximise possibilities forsynergy.
