events and N. Europe or British Isle
weather, without the modern satellite data some potential clues on these would be sudden outbreaks of extreme cold (20C or more below

The predicted increase in extreme
weather events, e.g., spells of high temperature and droughts (Meehl and Tebaldi, 2004; Schär et al., 2004; Beniston et al., 2007), is expected to increase yield variability (Jones et al., 2003) and to reduce
