Sahel Shrinking

New study finds world's largest desert, the Sahara, has grown by 10 percent since 1920,
National Science Foundation, March 30, 2018.

"The Sahara Desert has expanded by about 10 percent since 1920."

"It suggests that other deserts could be expanding as well."

"The trends in Africa of hot summers getting hotter and rainy seasons drying out are linked with factors that include increasing greenhouse gases and aerosols in the atmosphere."

"The results suggest that human-caused climate change, as well as natural climate cycles, caused the desert's expansion."

"The Sahara is the world's largest warm-weather desert, roughly equal in size to the contiguous United States."

"The southern border of the Sahara adjoins the Sahel, the semi-arid transition zone that lies between the Sahara and fertile savannas farther south... Lake Chad, which sits at the center of this transition zone, serves as a bellwether for changing conditions in the Sahel."

"...the lake is drying out... It's a very visible footprint of reduced rainfall not just locally, but across the whole region. It's an indicator of declining water in the Chad Basin."

"The results have far-reaching implications for the future of the Sahara and other subtropical deserts. As the world's population continues to grow, a reduction in land with adequate rainfall to support crops could have devastating consequences."

 We can see climate change driven ecological degradations pressurizing existing conflicts, and creating conflict where it did not before exist.
