    The exposure of populations to sea-level rise is a leading indicator assessing the impact of future climate change on coastal regions. The authors identify three spatial zones of flooding such as mean higher water, the 100 year floodplain and the low-elevation coastal zone and show population exposure can differ between those zones.

    Ammonia emissions from agricultural sources can cause severe health impacts. Here, the authors show that about 25% of global agricultural ammonia emissions in 2012 were related to international exported goods and caused 61 thousand PM2.5 related premature deaths, which points out large ammonia mitigation potential in international trade.

    Stabilizing climate change requires simultaneous mitigation of all greenhouse gas emissions (GHGs). Here the authors examine 90 mitigation scenarios pairing different levels of CO2 and non-CO2 GHG abatement pathways to demonstrate the contributions of different GHGs towards 1.5 °C and 2 °C goals.

    Current carbon accounting and reporting practices remain unsystematic and incomparable, particularly for emissions along the value chain (scope 3). Here the authors present a framework to harmonize scope 3 emissions by accounting for reporting inconsistency, boundary incompleteness, and activity exclusion.

    Microporous polymers become increasingly attractive as materials for the fabrication of permeable and selective gas separation membranes but separation performance is often limited by broad pore size distribution. Here, the authors design a porous polymer membrane via multi-crosslinking of miscible blends of microporous polymers enabling simultaneous high permeability and selectivity.

    Building construction causes large material-related emissions which present a serious decarbonization challenge. Here, the authors show that the building material sector could halve emissions by increasing efficiency until 2060 but even then its emissions would be twice as high as needed to meet the 1.5 °C target.

    The El Nino Southern Oscillation (ENSO) influences the weather around the world and, therefore, has strong impacts on society. Here, the authors show that ENSO is associated with child nutrition in many countries, with warmer El Niño conditions leading to more child undernutrition in large parts of the developing world.

    Though a global assessment of rooftop solar photovoltaic (RTSPV) technology’s potential and the cost is needed to estimate its impact, existing methods demand extensive data processing. Here, the authors report a machine learning method to realize a high-resolution global assessment of RTSPV potential.

    Heatwaves are becoming increasingly frequent and more intense, causing severe economic impacts through reduced labour productivity. Here, the authors show that economic damages in Europe exceed 1% of the GDP in vulnerable areas, which might increase by a factor of almost five in the medium term without climate action.

    There is much uncertainty on use and impact of pesticides in organic agriculture. Here, the authors compare pesticide use in conventionally and organically managed fields in Kern County (US), finding that organic fields are less likely to be treated but, when they are, they receive similar pesticide amount as the conventional fields.

    COVID-19 has decreased power sector emissions globally and in the United States. Here the authors assess whether such reductions would have occurred in the United States in the absence of the pandemic, as well as the potential impact of COVID-19 on coal-fired power plant retirements through 2022.

    Climate change is expected to have impacts on human mortality, e.g. through increases in heat waves. Here, the author proposes a new metric to account for excess deaths from additional CO2 emissions, which allows to assess the mortality impacts of marginal emissions and leads to a substantial increase in the social costs of carbon.

Results reveal contrasted patterns of viral diversity in patrilineal and matrilineal communities, consistent with cultural differences in modes of seed exchange.

    It has been suggested that younger people care more about climate change than older people. Here, the authors present ten year panel data from New Zealand and show that despite a generation gap in starting levels, climate change beliefs have increased at similar rates across ages over the 2009-2018 period.

    Predicting the risk of flooding in coastal environments relies on accurate land elevation data, but this is not available in many parts of the world. Here the authors apply a global lowland digital terrain model derived from satellite LiDAR and determine that the regions most vulnerable to sea-level rise are in the tropics.

    Afforestation is an important greenhouse gas (GHG) mitigation strategy but the efficacy of commercial (harvested) forestry is disputed. Here the authors apply dynamic life cycle assessment to show that new commercial conifer forests can achieve up to 269% more GHG mitigation than semi-natural forests, over 100 years.

    Ambient fine particulate matter (PM2.5) is one of the most important environmental health risk factors in many regions. Here, the authors present an assessment of PM2.5 emission sources and the related health impacts across global to sub-national scales and find that over 1 million deaths were avoidable in 2017 by eliminating PM2.5 mass associated with fossil fuel combustion emissions.

    Social inequalities may be reflected in how ecosystem services are distributed among groups of people. Here the authors estimate the distribution of three ecosystem services across demographic and socioeconomic groups in the US between 2020 and 2100, finding that non-white and lower-income groups disproportionately bear the loss of ecosystem service benefits.
