    The Paris Agreement is based on emission scenarios that move from a sluggish phase-out of fossil fuels to large-scale late-century negative emissions. Alternative pathways of early deployment of negative emission technologies need to be considered to ensure that climate targets are reached safely and sustainably.

    The fashion industry has changed rapidly in recent years with the increased prevalence of fast fashion, impacting the environment. Efforts to green this polluting industry require action from businesses and consumers.

    Photosynthesis is the foundation for almost all known life, but quantifying it at scales above a single plant is difficult. A new satellite illuminates plants’ molecular machinery at much-improved spatial resolution, taking us one step closer to combined ‘inside–outside’ insights into large-scale photosynthesis.

    Climate change could increase fire risk across most of the managed boreal forest. Decreasing this risk by increasing the proportion of broad-leaved tree species is an overlooked mitigation–adaption strategy with multiple benefits.

    Completely stopping fossil fuel use may not be enough to avoid dangerous climate change. Recent research on the mitigation potential of conservation, restoration, and improved land management demonstrates that natural solutions can reduce emissions and remove atmospheric CO2 while safeguarding food security and biodiversity.

    Assessing the dynamics of resilience could help insurers and governments reduce the costs of climate-risk insurance schemes and secure future insurability in the face of an increase in extreme hydro-meteorological events related to climate change.

    Investors will play a major role, whether active or passive, in climate change mitigation. To enable prudent decision-making, we propose three physically based engagement principles that could be used to assess whether an investment is consistent with a long-term climate goal.

    One of the greatest sources of uncertainty about future climate change is the path greenhouse gas emissions will take. Now research using a coupled model of human behaviour and climate finds that individual behaviour can significantly alter emissions trajectories and global temperature.

    Well-mixed water around 500 m depth in the Southern Ocean has been warming. Now research reveals how strengthening wind increases the volume of the warm water.

    The thinning of floating ice shelves around Antarctica enhances upstream ice flow, contributing to sea-level rise. Ice-shelf thinning is now shown to influence glacial movement over much larger distances than previously thought.

    After years of working towards a climate accord, the Paris Agreement of 2015 marked the shift from negotiating to reach consensus on climate action to implementation of such action. The challenge now is to ensure transparency in the processes and identify the details of what is required.

    Debate over effective climate change communication must be grounded in rigorous affective science. Rather than treating emotions as simple levers to be pulled to promote desired outcomes, emotions should be viewed as one integral component of a cognitive feedback system guiding responses to challenging decision-making problems.

    Stable layering in the ocean limits the rate that human-derived carbon dioxide can acidify the deep ocean. Now observations show that ocean warming, however, can enhance deep-ocean acidification through increased organic matter decomposition.

    Large, intense thunderstorms frequently cause flooding and fatalities. Now, research finds that these storms may see a threefold increase in frequency and produce significantly heavier downpours in the future, far exceeding previous estimates.

    The Paris Agreement has increased the incentive to verify reported anthropogenic carbon dioxide emissions with independent Earth system observations. Reliable verification requires a step change in our understanding of carbon cycle variability.
