New research investigating the transition of the Sahara from a lush, green landscape 10,000 years ago to the arid conditions found today, suggests that humans may have played an active role in its desertification.
The desertification of the Sahara has long been a target for scientists trying to understand climate and ecological tipping points. A new paper published in Frontiers in Earth Science by archeologist Dr. David Wright, from Seoul National University, challenges the conclusions of most studies done to date that point to changes in the Earth's orbit or natural changes in vegetation as the major driving forces.

A Montana State University assistant professor of sustainable food systems who has conducted research all over the world is turning her attention to maple syrup.
Some farmers in the United States and Canada have noticed that the quantity and quality of their maple syrup is changing with climate variability, said Selena Ahmed from MSU's Department of Health and Human Development in the College of Education, Health and Human Development. Ahmed is co-leading a team of researchers who are investigating these observations.
