Current scientific estimates of climate change are as follows. Sea level rise thereafter is expected to accelerate, rising a total of 0.5 to 2 meters between 1990 and 2100. Sea level rise and land subsidence are additive. Area of occurrence, seasonal duration, and intensity of cyclones could change. Other things being equal, as mean magnitudes increase, extreme events of a given magnitude occur more frequently.
Similar arguments apply number of temperature etc.
Other things being equal, variances increase as means increase. Current understanding of the effect of these climatic changes on farming systems is not very far advanced, with research interest in mid-latitude agriculture predominating in the literature. Precipitation, evaporation, transpiration, etc., can all change. Existing long-lived infrastructure may be outpaced. Longer growing season in frost-affected areas.
