  • For decades, ozone pollution mitigation efforts relied on two chemical regimes. A global modelling analysis has revealed a third regime involving aerosols that would help with the concurrent control of both ozone and particulate pollution.

  • The bulk crustal porosity of the lunar highland may have been generated early in the Moon’s history by basin-forming impacts and then declined exponentially. A new porosity evolution model constrains the timing and sequence of basin formation.

  • Ozone depletion is not only a serious health threat but can also affect the climate. Atmospheric chemistry models reveal that springtime Arctic ozone depletion can have major consequences for the seasonal climate in the Northern Hemisphere, including warming over Eurasia and drying across central Europe.

  • Coastal evolution simulations suggest that the modern retreat of coastal barrier islands is controlled by cumulative sea-level rise over the past several centuries and will accelerate by 50% within a century, even if sea-level rise remains at present rates.

  • The Azores High over the North Atlantic has expanded due to anthropogenic climate change, disrupting precipitation patterns in western Europe, according to climate modelling and precipitation proxy records spanning the past millennium.

  • Monitoring of the daily global CO2 emissions in 2020 reveals the spatial–temporal pattern of the drop in emissions due to the impact of the COVID-19 pandemic. The daily CO2 emission changes also reveal different patterns of human activities and fossil CO2 emissions across countries, sectors and periods.

  • Unrest episodes observed in basaltic systems indicate magma influx rates may be key to generating long-term eruption forecasts. The findings predict that, if a critical flow rate is surpassed, a volcano will erupt within a year.

  • Using magma inflow rate improves eruption forecasting on timescales of weeks to months for basaltic caldera systems, compared with using surface deformation alone, according to analysis of 45 unrest case studies and viscoelastic modelling.

  • Recent missions to the rubble-pile asteroids Bennu and Ryugu have revealed asteroid surfaces that continue to be actively modified by a variety of processes while also recording the geologic history of these small bodies.
