Southwest deserts produce more dust during warm periods, unlike global trends. A UNM study found this region's dust emissions peak during interglacial climates, not cold glacial ones, based on a 230,000-year sediment record. This pattern is linked to landscape disturbance and vegetation shifts, with implications for climate modeling and potential increases in dust due to modern human activities and warming.
