  • As a source of soluble iron, anthropogenic combustion iron is considered less important than natural sources. Here, the authors combine new measurements with a global aerosol model and show the atmospheric burden of anthropogenic combustion iron to be 8 times greater than previous estimates.

  • Black carbon has a large but uncertain warming contribution to Earth’s climate. Here Matsui et al. show that black carbon mixing state and its interaction with aerosol size distribution are required for accurately estimating the radiative effect of black carbon.

  • Feedbacks between desert dust and climate might have amplified past climate changes, yet their role in future climate change is unclear. Here the authors find that dust feedbacks could play a key role in the future climates of Northern Africa, the Sahel, the Mediterranean, the Middle East, and Central Asia.

  • The relative importance of crustal vs. anthropogenic dust deposition for iron cycling in the surface ocean is unclear. Based on analysis of iron isotope data from North Atlantic aerosol samples, the authors can reveal the relative importance of anthropogenic iron emissions and its impact on marine biogeochemistry.

  • Today, most operational dust forecasts extend only 2-5 days. New research finds that the stratosphere exerts long-lasting influence on Saharan dust emission and transport, contributing to subseasonal predictability for dust and air pollution over West Africa and the Eastern Mediterranean.

  • Metal dissolution from atmospheric aerosol deposition plays an important role in enhancing and inhibiting phytoplankton growth and community structure. Here, the authors review the impacts of trace metal leaching from natural and anthropogenic aerosols on marine microorganisms over short and long timescales.

  • Dust influences the global energy budget through various Earth system interactions. This Review outlines these interactions, revealing a total radiative effect of −0.2 ± 0.5 W m−2, which, alongside 55 ± 30% historical increases in dust, have contributed a radiative forcing of −0.07 ± 0.18 W m−2.

  • Atmospheric transport of microplastics could be a major source of plastic pollution to the ocean, yet observations currently remain limited. This Perspective quantifies the known budgets of the marine-atmospheric micro(nano)plastic cycle and proposes a future global observation strategy.

  • Deposition of Siberian wildfire aerosols, which contained nitrogen, enhanced phytoplankton growth in the eastern Eurasian Basin of the Arctic Ocean in summer 2014, suggest satellite-based ocean color data and atmospheric transport modeling.
