Key Climate Change Projections for Northern Ireland by 2050s
UKCP09 projects significant temperature increases, precipitation changes, and sea level rise for Northern Ireland, along with increased frequency of extreme weather events including heatwaves, droughts, heavy rain and flooding.
UKCP09 indicates an increased preponderance of hotter drier summers and warmer wetter winters, coupled with increased frequency of extreme weather occurrences such as heatwaves, dry spells, heavy rain and flooding. Some of the key findings from the Climate Change Projections estimate that by the 2050's Northern Ireland will have:
• An increase in winter mean temperature of approximately 1.7 °C;
• An increase in summer mean temperature of approximately 2.2°C;
• Changes in winter mean precipitation of approximately +9%;
• Changes in summer mean precipitation of approximately -12%; and
• Sea level rise for Belfast of 14.5cm above the 1990 sea level.
