March Lecture: Ireland’s Changing Climate in a Warming World
22nd March, The Custom House
6.30pm - 7.30pm (refreshments at 6pm)
Speaker: Séamus Walsh is the Head of the Climatology and Observations Division in Met Éireann. He was a weather forecaster for over twenty years before moving into research, where he specialised in the provision of climate services to the agricultural and environmental sectors. His main areas of work are past data analysis, observation networks and generation of long term datasets for Ireland. He compiled the 1981-2010 Long Term Average datasets for Ireland and has contributed to various publications on the climate of Ireland.
Abstract: Warming of the world since the 19th century is unequivocal, the global mean temperature is projected to continue to increase by between 1.5 and 4.5 degrees Celsius by the end of the 21st century, depending on future levels of emission of greenhouse gases. Changes in the Earth’s climate system such as increases in air and sea temperature, sea level rise and decreasing extent of Arctic sea ice and glaciers, which have already been observed, will continue to occur, with changes also likely in precipitation patterns and extremes. The presentation will place these global changes in the Irish context, a future warmer climate in Ireland will bring more frequent wet winters, drier and hotter summers and an increased likelihood of extreme weather events , with implications for many sectors of society.
