One possibility for the future of Norfolk's climate is that it might actually get colder.

Should this happen, it would be down to an unexpected event - a flip in the climate of a local area, triggered by rising global temperatures. Scientists suggest these types of events may happen, but are unable to determine their likelihood with any kind of certainty.

The possibility of a change in the strong ocean currents that transport heat around the world is suggested as one such event. The North Atlantic Drift, for example, which passes right by Norfolk's front door, could potentially cease to exist. At the moment the North Atlantic Drift keeps the UK a balmy few degrees higher than we would otherwise be.

Another area of concern is the behaviour of the West Antarctic Ice Sheet (WAIS). It is possible that a more rapid sea level rise than suggested in current scenarios could occur should the WAIS begin to disintegrate.
