Climatic Change and Long-Term Climatic Variability

Abstract

This chapter reviews both climatic change and climatic variability in the Southern Hemisphere. While its scope concentrates on the changes and processes that have occurred during the twentieth century, particularly since 1950, it also attempts to bring together much paleoclimatic data and consider whether “pseudo-cyclic” phenomena, such as the El Niño-Southern Oscillation, have influences on longer timescales.
