Study Supplies Insight into Behavior of African Monsoon
Think of the Sahara and you will conjure images of a vast desert landscape, with nothing but sand as far as the eye can see. But for a period of about 10,000 years, the Sahara was characterized by lush, green vegetation and a network of lakes, rivers and deltas.
This “green Sahara” occurred between 14,800 and 5,500 years ago during what is known as the “African Humid Period.” Why and how it ended is the subject of scientific study that holds important information for predicting the region’s response to future climate change.
In a study published this week in Nature Geoscience, a team of researchers provides new insight into the behavior of the African monsoon at the end of the African Humid Period and the factors that caused it to collapse.

As the ocean ‘s pH decreases and acidifies, coral reefs are more likely to begin dissolving and “drown”. A new study shows exposing corals to added nutrients increases their erosion and dissolution rate tenfold.
