Trouble at the Source of the Blue Nile in the Ethiopian Highlands

Upper Nile will experience more water scarcity due to hotter, drier periods,
AGU Blogosphere, August 28, 2019.


The Problem
"An increase in hotter, drier years in the coming decades due to climate change may worsen water scarcity issues in the Upper Nile Basin."

Failure & Failure
"This region is already on the verge of water scarcity..."

"...impacts are likely to cause an increase in agricultural failure in Ethiopia and may potentially lead to civil strife, according to the authors..."

Increasing Extremity
Rain and Drought Increasing
"Climate models generally agree that rainfall will increase by roughly 10 percent by 2080 in the regions around the upper branches of the Nile River."

Dry Years
From One in Five to Every Second Year...
"...that while rainfall will increase on average, projections show years experiencing year-long average temperatures hotter than 22 degrees Celsius (71.6 degrees Fahrenheit) and below about 106 millimeters (4.2 inches) of rain per year will double or triple in frequency by 2080. Such high average temperatures currently only occurs one of every five years in the area."

Extreme Extremes
"What this means in practice is that the rainier years will experience more rain, but the dry, hot years will be drier and hotter."

Other Edge of the Sword
"...population in the area is projected to double by 2100."
