Evidence for an anthropogenic influence on climate change is now stronger than ever before, with the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report assertion that ‘It is very likely that anthropogenic greenhouse gas increases caused most of the observed increase in globally averaged temperatures since the mid-20th century’ (IPCC, 2007a). Global average temperature has increased by 0.74oC over the past 100 years with the rate of warming almost doubling over the last 50 years. Precipitation patterns have also changed with an increase in the number of heavy precipitation events being observed globally. Within this context, the following report will outline the spatial and temporal variation in the observational surface climate record, including temperature, precipitation and extreme events, based on daily synoptic station data from the Met Éireann database. Temporal and spatial variability of these climatic indicators is studied to determine whether the model projections from the latest Intergovernmental Panel on Climate Change (IPCC), (2007a) report can already be seen in the Irish observational record (See Appendix 1 for model projections). This work reviews and develops analysis in Climate Change: Indicators for Ireland (2002).
