Artificial intelligence reveals an unexpectedly large count of trees in the West African Sahara and Sahel

What’s Going On Here? A team of international scientists combined detailed satellite imagery with a deep learning algorithm and managed to find millions of trees in the West African Sahara and Sahel. Using this kind of beneficial AI technology will contribute to a better understanding of the importance of trees outside of forested areas and their role in mitigating degradation, climate change…

Trees uptake of carbon dioxide predicted to drop as rising temperatures make autumn leaves fall earlier

What’s Going On Here? New research predicts that global heating will cause trees to drop their leaves three to six days earlier than expected. Consequently, forests will absorb and store significantly less carbon dioxide than scientists had hoped. What Does This Mean? In preparation for the coming winter, leaves of deciduous trees change their colour while suspending growth and extracting nutrients. This…
