Jet streams sprinkle North African dust over the Amazon, providing the rain forest with much needed nutrients. Changing wind patterns and increasing smoke may shift the system.
The first time series of bi-weekly dust concentrations measured in-situ across the remote Atlantic Ocean.
The Saharan dust that crosses the Atlantic and fertilizes the Amazon may be coming from the El Djouf region between Mauritania and Mali, which is farther west than previously thought.
Saharan dust events can spread bacterial pathogens over long distances, but we may be able to predict the human health risk from exposure.
New research on the geochemistry of Canary Islands paleosols shows that the Sahara has been an arid dust producer for at least 4.8 million years.
Past climate change likely motivated human migrations.
