WHAT’s NEW?
Our new paper, published in Science Express (Feb 08), quantitatively constrains glacial-interglacial dust flux variability in the tropics, a key parameter in dust and climate models, and shows that dust fluxes from interhemispheric sources to the equatorial Pacific have been coherent in timing with dust fluxes to polar regions for the last 500,000 years, suggesting that processes regulating dust generation have a consistent relationship to global climate change.
