“This research comprehensively described the occurrence of extreme weather and climate events and aspects of sea level rise that are relevant from the view point of safety of nuclear power plants. Studies about the frequency, intensity, and spatial and temporal variation of the extreme weather events and their combinations were carried out utilising instrumental meteorological observations, a 1 200-year long preindustrial control simulation and future climate model simulations. In addition to the role of natural climate variability, the study clarified the influence of human-induced climate change on extreme weather events and sea level values. The longest future climate and sea level projections extend to the end of the 21st century. According to them, the daily maximum temperatures and the length of the longest hot spells will clearly increase in Finland. The largest changes, however, are projected for the wintertime minimum temperatures. During summer there will be more intensive precipitation events and during winter more frequent precipitation days. The mean sea level is projected to rise, the change depending on the location along the Finnish coastline. Uncertainty ranges in the mean sea level scenarios are large mainly due to uncertainties in the future behaviour of the continental ice sheets.” end quote. Please see original link above.
