    Urban development induces local warming in addition to climate change. New research shows that urban growth, climate change and urban adaptation interact nonlinearly and diurnally.

    Urban expansion and climate change interact to produce less night-time warming than their sum. Combined implementation of adaptation strategies can offset projected daytime urban warming when applied with GHG emissions reductions, but cannot offset projected nocturnal warming.

    Extensive evidence reveals that Earth’s snow cover is declining, but our ability to monitor trends in mountain regions is limited. New satellite missions with robust snow water equivalent retrievals are needed to fill this gap.

    Global snow coverage has declined substantially with anthropogenic warming, impacting biological, socio-economic and physical systems. This issue includes a suite of Comments, Reviews, Perspectives and original research documenting the importance of snow in the climate system, and how this may change with continued warming.

    The current focus on the long-term global warming potential in climate policy-making runs the risk of mitigation options for short-lived climate pollutants being ignored, and tipping points being crossed. We outline how a more balanced perspective on long- and short-lived climate pollutants could become politically feasible.

    Snow albedo is impacted by the presence of light-absorbing particles, including black carbon and dust. This Review collates knowledge on the associated radiative forcing, discussing geographic variability, future impacts and challenges for reducing uncertainty.

    Indigenous reindeer herding in the circumpolar North is threatened by multiple drivers of environmental and social changes that affect the sustainability of traditional family-based nomadic use of pastures. These impacts are exacerbated by indigenous peoples’ lack of voice in governance strategies, management and adaptation responses.

    Bitcoin is a power-hungry cryptocurrency that is increasingly used as an investment and payment system. Here we show that projected Bitcoin usage, should it follow the rate of adoption of other broadly adopted technologies, could alone produce enough CO2 emissions to push warming above 2 °C within less than three decades.

    Climate and land-cover change can affect the summer and winter ranges and migration distances of migratory birds. Accounting for all of these factors, rather than just summer range as is typical, significantly increases the number of species under threat.

    Winter snow conditions influence which plants grow where in the Arctic. Now, a modelling study built on observational data of plant occurrence and snow conditions suggests that declines in snow cover will result in the loss of plant species.

    Projected sea-level rise and increased flooding threaten coastal agriculture. Gradual increases in soil salinity, but not inundation alone, are shown to correspond to increasing diversification into aquaculture and higher levels of internal migration.

    Climate change, in combination with existing environmental issues, threatens the Mediterranean region. This Review highlights how climate change will interact with other factors to exacerbate five areas of risk unless there is mitigation and adaptation.

    The impact of coral bleaching and mortality is found to reduce aggression in resident butterflyfish. This is linked to the lower dietary percentage of preferred food, nutritionally rich Acropora coral, with a less nutritious diet influencing aggressive behaviour.

    Observations show that the Atlantic Meridional Overturning Circulation (AMOC) is slowing down, and this is predicted to continue in response to climate change. This isn’t the only change expected; tracing ocean circulation within a climate model now shows that the locations where water sinks to the deep ocean to feed the AMOC will also shift in the future.

    Scenarios have supported assessments of the IPCC for decades. A new scenario ensemble and a suite of visualization and analysis tools is now made available alongside the IPCC 1.5 °C Special Report to improve transparency and re-use of scenario data across research communities.

    A combination of consumption-based emissions modelling and deliberative public workshops suggests that developing resource-efficient products will be an effective climate change mitigation strategy because it has both high emissions-reduction potential and wide-scale public approval.

    Climate change mitigation scenarios are finding a wider set of users, including companies and financial institutions. Increased collaboration between scenario producers and these new communities will be mutually beneficial, educating companies and investors on climate risks while grounding climate science in real-world needs.

    Adjustments in the timing of seasonal events can seem like a relatively subtle impact of climate change, but one with potentially large ramifications for the health of ecosystems and the services they provide.

    Biological communities beneath Antarctic ice shelves remain a mystery, hampering assessment of ecosystem development after ice-shelf collapse. Here we highlight major gaps in understanding of the patterns and processes in these areas, and suggest effective ways to study the ecological impacts of ice-shelf loss under climate change.

    Climate change will almost certainly cause millions of deaths. Climate engineering might prevent this, but benefits — and risks — remain mostly unevaluated. Now is the time to bring planetary health research into climate engineering conversations.

    Recent years have seen increased melting of the Greenland Ice Sheet, contributing to accelerated rates of sea-level rise. New research suggests that this melting occurred due to an increased frequency of atmospheric rivers, narrow filaments of moist air moving polewards.

    Global estimates of the economic impacts of CO2 emissions may obscure regional heterogeneities. A modular framework for estimating the country-level social cost of carbon shows consistently unequal country-level costs.

    The model–inventory discrepancy in net land-use carbon emissions mainly results from conceptual differences in estimating anthropogenic forest sinks. A revised disaggregation of global land model results allows greater comparability with inventories.

    Deep reefs and their inhabitants are diverse, but environmental change, in particular warming, will cause these reefs found along southeastern Australia to tropicalize with different responses across functional groups, resulting in novel communities by the 2060s.
