is much lesser, leading to extraordinary temperature oscillations (Sánchez-Laulhé

3.1.5 Climate Trends and Climate Change
The Mediterranean is often referred to as a climate change “hotspot” since it exhibits
larger changes than many other regions of the globe (Giorgi 2006; Giorgi and
Lionello 2008).
Precipitation and temperature in the Mediterranean during the twentieth century
show significant trends. Gauge-based reconstructions, gauge-satellite merged products, and atmospheric reanalyses have indicated a negative precipitation trend for the
Mediterranean in winter in the twentieth century (Giorgi 2002; Mariotti et al. 2002),
although high uncertainties affect the observation records in the early part of the
century. Besides, the extent to which the anthropogenic climate change has contributed to the observed trend is still unknown due to limited knowledge of the
