    Transformation of the land sector is required to meet the Paris Agreement goal of limiting warming to 1.5 °C. Here, modelled emission pathways and mitigation strategies are reviewed. A land-sector roadmap of priority measures and key regions is presented.

    The resilience of a marine food web to climate change is investigated through a combination of multiple and nested species interactions. The Kongsfjorden food web adapts and maintains core ecological processes during change, with increasing dominance of Atlantic species boosting resilience.

    Winter warming in the Arctic will increase the CO2 flux from soils. A pan-Arctic analysis shows a current loss of 1,662 TgC per year over the winter, exceeding estimated carbon uptake in the growing season; projections suggest a 17% increase under RCP 4.5 and a 41% increase under RCP 8.5 by 2100.

    Climate change is expected to impact river flows. Here, it is shown that plant physiological responses to increased CO2, rather than atmospheric changes, are the primary drivers of mean, peak and low flows throughout the tropics.

    This study shows that expressing uncertainty about best- and worst-case effects of climate change on sea-level rise increases trust in climate scientists and message acceptance but not when the full extent of inevitable uncertainty due to unpredictable storm surges is also acknowledged.

    The effects of global warming are felt earlier in Arctic regions than elsewhere in the world. Now research shows that Arctic marine food webs can adapt to climate change — but the study authors warn that this impression of resilience may be false in the long term.

    Warming in the Arctic is causing soils to decompose more rapidly, even during winter. Now, estimates of winter carbon dioxide loss indicate that it can offset carbon gains during the growing season, meaning that the region is a source of carbon.

    The consequences of global warming will be dire, but the full extent of these effects on society is unknown and includes uncertainties. Research now suggests that how scientists communicate about the uncertainty over such climate change impacts can influence the public’s trust and acceptance of this information.

    Predicting coral bleaching is critical to better manage and preserve coral reefs from global warming. An impressive coordination of surveys across oceans now offers new metrics to help to predict coral bleaching events on a global scale.
