MADRID, April 30 (UPI) -- Writings by Arab historians offer a chronology of climatic events in the Middle East from 816 to 1009, when cold waves and snow were normal, researchers say.
A team led by Spanish scientists has interpreted records written in Iraq that chronologically narrate social, political and religious matters but also mention climate. The researchers focused on ancient meteorological notes of the Iraqi city of Baghdad, the Spanish Foundation for Science and Technology reported Monday.
