This chapter contains sections titled:

  • Observed and modelled sea-surface temperature data from the north Atlantic have been collected to identify trends and investigate the spatial variability of these trends. Data obtained from the Reynolds sea-surface temperature data set have been used to examine temperature trends over the last 20-40 years. Predicted sea-surface temperature data, obtained from the climate model HADCM3, are used to examine trends over the next 20-50 years. Understanding of the cause of past trends is the key to predicting future changes. The modelled data are presented as our best estimate so far of the changes that will take place in the marine habitat of Atlantic salmon. It is clear that the last decade has been a period of warming and it is likely that this trend will continue in the future. The rate of warming in the future may be lower than we have seen over the past decade and will vary across the different regions, with some areas experiencing cooling.
