We present an annual reconstruction of temperature and aridity derived from Sr/Ca and oxygen isotopes in a coral of the desert-surrounded northern Red Sea. Our data indicate that the eastern Sahara and Arabian Deserts did not experience pronounced cooling during the late Little Ice Age (~1750-1850) but suggest an even more arid mean climate than in the following ~150 years. The mild temperatures are broadly in line with predominantly negative phases of the North Atlantic Oscillation during the Little Ice Age. The more arid climate is best explained by meridional advection of dry continental air from Eurasia. We find evidence for an abrupt termination of the more arid climate after 1850, coincident with a reorganization of the atmospheric circulation over Europe. #------------------ # Publication # Authors: Thomas Felis, Jürgen Pätzold, Yossi Loya, Maoz Fine, Ahmed H.

The mean annual coral d18O signal apparently reflects varying proportions of both sea surface temperature and d18Oseawater variability. In conjunction with instrumental observations of climate the coral record suggests for interannual and longer timescales that colder periods are accompanied by more arid conditions in the northern Red Sea but increased rainfall in the southeastern Mediterranean, whereas warmer periods are accompanied by decreased rainfall in the latter and less arid conditions in the northern Red Sea. A ~70-year oscillation of probably North Atlantic origin dominates the coral time series. Interannual to interdecadal variability is correlated with instrumental indices of the North Atlantic Oscillation (NAO), the El Nino-Southern Oscillation (ENSO), and North Pacific climate variability. The results suggest that these modes contributed consistently to Middle East climate variability since at least 1750, preferentially at a period of ~5.7 years. #------------------ # Funding_Agency # Funding_Agency_Name: Deutsche Forschungsgemeinschaft # Grant: #------------------ # Site_Information # Site_Name: Ras Umm Sidd # Location: Ocean>Indian Ocean>Red Sea # Country: # Northernmost_Latitude: 27.85 # Southernmost_Latitude: 27.85 # Easternmost_Longitude: 34.32 # Westernmost_Longitude: 34.32 # Elevation: -6 m #------------------ # Data_Collection # Collection_Name: RasUmmSidd2018ann # Earliest_Year: 1751 # Most_Recent_Year: 1994 # Time_Unit: AD # Core_Length: 2.6 m # Notes: #------------------ # Chronology_Information # Chronology: # #---------------- # Variables # # Data variables follow are preceded by "##" in columns one and two. # Data line variables format: one per line, shortname-tab-variable components (what, material, error, units, seasonality, data type,detail, method, C or N for Character or Numeric data, free text) # ## age_CE age, , , years CE, , , , ,N, ## d18O delta 18O, Porites sp., , per mil VPDB, annual, Corals and Sclerosponges,,isotope ratio mass spectrometry,N, ## Sr/Ca strontium/calcium, , , mmol/mol, annual, Corals and Sclerosponges, , ,N, ## SSTanom Sea Surface Temperature anomaly, , , deg C, annual, Climate Reconstructions, , ,N,calculated using annual mean proxy-temperature relationship: [-0.140 mmol/mol per degC; Felis et al.
