Presentation from the workshop 'Informing and Enabling a Climate Resilient Ireland”' - held 23 March 2012. This event launched 2 EPA Climate Change Research Programme reports:
CCRP9 'Ireland adapts to Climate Change' and CCRP10 'Integrating Climate Change Adaptation into Sectoral Policies in Ireland'
2. 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

5. 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, landslides
and the spread of agricultural pollutants

18. 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 ocean
acidity monitoring, data homogenisation and analyses)
•Appropriate long-term climate observation sites should be identified
for variables monitored under other programmes (e.g. river flows and
lake levels as part of the Water Framework Directive; sea state for
ocean weather forecasting)
• Need for co-ordination between different bodies carrying out climate
monitoring to avoid duplication and to maximise possibilities for
synergy.

19. Ireland’s Climate Observation System is relatively
Robust…..
…but a national commitment to long-term monitoring
AND analyses of the full suite of ECVs is essential to
allow us understand how our climate is changing
