  • Experiments in diverse soils reveal an extremely low moisture threshold for H2-oxidizing microbes, near the dry limit for microbial activity. This finding shifts the soil H2 sink distribution, underscoring the role of drylands in the global H2 cycle.

  • The 100-year Global Warming Potential of hydrogen falls in the range 11.6 ± 2.8, according to chemistry-model estimates, through its chemical impact on methane, ozone and stratospheric water vapor. It is therefore important to avoid leakages in a hydrogen economy, to help mitigate climate change.

  • The acidity of inorganic aerosols in remote areas is often higher than predicted by chemical transport models, which may lead to an underestimation of direct radiative cooling, according to global aircraft observations of pH and ammonium balance in aerosols

  • Most research on the impacts of food loss and waste (FLW) looks at food security, resource use and climate. Based on product-level FLW data and an NH3 emission inventory, atmospheric chemistry simulations reveal the potential of FLW reductions in mitigating PM2.5 air pollution and nitrogen deposition.

  • H2 has the potential to become the green, low-carbon fuel of the future. However, hydrogen emissions impact atmospheric methane (CH4). Bertagni et al. investigate the fate of atmospheric CH4 in scenarios of H2 economy.

  • Despite strict controls on precursor emissions, ozone air pollution has not decreased over Europe in recent decades. This is largely attributed to water-stressed vegetation; during heatwaves and drought, plants are less effective at ozone removal via stomata, worsening peak ozone pollution episodes.

  • Transitioning to a hydrogen economy has the potential to mitigate carbon dioxide emissions. The hydrogen leakage rate and the production pathways appear, based on simulations with a global model, as key leverages to reach a clear climate benefit from a large-scale transition to a hydrogen economy.
