Choose two sentences from the passage that best help explain why the
author concludes that the Sahara Desert is flourishing, not expanding.
Today, the opposite effect of climate change is occurring. Warming air
currents hold moisture from the oceans, which cooler air could not do well.
These warmer air currents carry this moisture across the land, dropping it as
rain. Because of this, the Sahara is becoming more fertile every year.
Scientist Martin Claussen agrees with these findings. He analyzes satellite
images of the Sahel, a semiarid region that borders the Sahara along its
southern edge. These images show enormous increases in plants and trees
in several areas. The water-holding capacity of the air is the main driving
force," he says.
