Abstract
Sea level and climate changes archived in various coastal environments during the last part of the last glacial and present interglacial
periods are investigated by interpolating available geomorphology, sedimentology, palaeontology and geochronology data. The coastal
response to these changes depended on the environment and geographic location. Changes of sea level during the rising, transgressive
phase are well recorded in the sedimentary filling of the estuaries, whereas during the phase of highstand they are best recorded in
beach–barrier environments. The postglacial rise of sea level took place in two phases: a rapid rise until 6500 cal BP, and a second phase
of near stability with minor oscillations of metric magnitude. Regarding climate changes, there is no record of changing temperatures in
the coastal zones of southern Spain, although there is in precipitation and wind intensity/velocity. After 7–5 cal ka BP, the general
climatic trend towards aridity was punctuated by several short-lived (centennial) episodes of increased aridity that occurred with a
millennial cycle, often coincident with Bond cool events and, in some cases, with decreases of sea surface temperatures. The absence of
human intervention in vegetation composition until 2000 BP suggests that most environmental coastal shifts were climatically driven.
