An article in Atmospheric Chemistry & Physics examines the impact of ice-nucleating particles in marine aerosols on an atmospheric river event in the western United States.

Kimberley Marshall-Mills explains the use of electron backscatter diffraction in resolving (sub-)microscale structures in clam shells.

Joeri Reinders explains how geomorphic and sedimentary evidence from river channels can extend flood records beyond the instrumental period.

Tropical peatlands hold around 105 gigatonnes of carbon but are increasingly affected by anthropogenic activities. This Review describes the biogeochemistry of these systems and how deforestation, fire, drainage and agriculture are disturbing them.

Biochar is a promising negative carbon emission technology with applications in wastewater pollution control. This Review assesses the performance of engineered biochar in various industrial, municipal and stormwater treatments, and discusses the partnerships required for biochar commercialization.

Clay minerals can retain metal ions, concentrate rare earth elements and be exploited for industrial waste disposal. This Review discusses the molecular-level mechanisms of metal ion retention in clay minerals and their importance for environmental and industrial applications.

Vegetation dynamics can be tracked using remotely sensed vegetation indices, but these metrics can result in conflicting conclusions. This Technical Review details the history, application and potential pitfalls associated with vegetation indices and makes recommendations for their best use.
