6 Strengthening of North American dust sources during the late Pliocene (2.7 Ma).

The article discusses the terrestrial higher plant leaf wax inputs to the North Atlantic Ocean in the late Pliocene era, as well as their effects on global climate change. It claims that the aeolian input of terrestrial material in the ocean coincided with the intensification of the Northern Hemisphere glaciation (NHG). It cites that continental ice sheets are major dust sources, which are said to play a key role in simulating a complete glacial cycle. It employs materials from the Integrated Ocean Drilling Project (IODP) to analyze if changes in aeolian input are related in the intensification of NHG.
