The 4.2 ka BP event in the Levant
<p>The 4.2 ka BP event is defined as a phase of environmental stress characterized by severe and prolonged drought of global extent. The event is recorded from the North Atlantic through Europe to Asia and has led scientists to evoke a 300-year global mega-drought. For...

<p>The 4.2 ka BP event is defined as a phase of environmental stress
characterized by severe and prolonged drought of global extent. The event is
recorded from the North Atlantic through Europe to Asia and has led
scientists to evoke a 300-year global mega-drought. For the Mediterranean and
the Near East, this abrupt climate episode radically altered precipitation,
with an estimated 30 %–50 % drop in rainfall in the eastern basin. While many
studies have highlighted similar trends in the northern Mediterranean (from
Spain to Turkey and the northern Levant), data from northern Africa and
the central-southern Levant are more nuanced, suggesting a weaker imprint of this
climate shift on the environment and/or different climate patterns. Here, we
critically review environmental reconstructions for the Levant and show that,
while the 4.2 ka BP event also corresponds to a drier period, a different
climate pattern emerges in the central-southern Levant, with two arid phases
framing a wetter period, suggesting a W-shaped event. This is particularly
well expressed by records from the Dead Sea area.</p> |
