A new study conducted by University of Arizona (UA)
researchers has found that the continued warming of the Earth's climate has
turned the Horn of Africa, long considered to be the cradle of early human
life, into an increasingly arid region at an unprecedented rate. This African
region has also experienced catastrophic droughts every few years over the past
several decades.
According to the scientists, if the planet continues to
become warmer, the eastern part of the Horn of Africa, which covers the
countries of Ethiopia, Djibouti and Somalia, will also continue to receive
lessening amounts of rainfall during the traditional "long rains"
season in the region, from March until May. Such a negative trend could result
in the exacerbation of tensions in some of the world's most geopolitically
unstable nations.
In a previous study, Tierney and fellow researcher Peter
deMenocal revealed that the Sahara desert, which was once teeming with
vegetation because of regular rainfall, suddenly dried out in just one to two
centuries around 5,000 years ago. The findings of the UA scientists show that
shifts in climates can occur suddenly.
