    On average, El Niño events have weakened and the centre of maximum sea surface temperature anomalies has shifted to the west over the past two decades. New research suggests that the strengthening of cross-equatorial winds in the eastern Pacific can cause these changes.

    The coincident reduction of Arctic sea ice with increasing mid-latitude wintertime extremes has motivated much research on Arctic–mid-latitude linkages. A new study reveals that projected Antarctic sea-ice loss could also impact the Southern Hemisphere mid-latitudes through perturbations to the strength and position of the westerly winds.

    With country-specific development objectives and constraints, multiple market failures and limited international transfers, carbon prices do not need to be uniform across countries, but must be part of broader policy packages.

    It is increasingly clear that achieving the Paris Agreement goal of limiting warming to well below 2 °C will require radical decarbonization, the prospects of which have become closely tied to carbon pricing.

    Protecting and restoring forests to mitigate climate change also promises to help protect tropical biodiversity and ecosystem services. Analysis now shows that optimizing for carbon can come at the expense of protecting biodiversity, but there are ways to effectively pair the two.

    A well-defined relationship between global mean sea-level rise and cumulative carbon emissions can be used to inform policy about emission limits to prevent dangerous and essentially permanent anthropogenic interference with the climate system.

    Will the Southern Ocean’s relentless waves undo Antarctica’s ecological isolation? The discovery of a wayward piece of kelp and a simple numerical experiment set new expectations for the potential invasion of Earth’s most isolated continent.

    Political crises may exacerbate environmental conflicts by shifting conservation priorities. Research now shows that increased carbon emissions from deforestation in Brazil may compromise its goals under the Paris Agreement.

    Plant transpiration is the largest continental water flux. Research now shows that climate and water availability projections are highly sensitive to the ways that plant responses to changing atmospheric conditions are represented.

    The high points of collective ambition and achievement reached in Paris need nurturing to ensure results. Maintaining momentum in climate action requires investment and ongoing commitment from all actors.

    The atmospheric concentration of CO2 at the time of passing 1.5 °C or 2 °C is unknown due to uncertainties in climate sensitivity and the concentrations of other GHGs. Impacts studies must account for a wide range of concentrations to avoid either over- or underestimating changes in crop yields and land and marine biodiversity.

    A global effort is underway to restore more than 350 million hectares of deforested and degraded land by bringing together reforestation commitments under the Bonn Challenge. Molly Hawes investigates the benefits and complexities of returning land to forest.

    In key European cities, stabilizing climate warming at 1.5 °C would decrease extreme heat-related mortality by 15–22% per summer compared with stabilization at 2 °C.

    Climate change-driven alterations in storminess pose a significant threat to global capture fisheries. Understanding how storms interact with fishery social-ecological systems can inform adaptive action and help to reduce the vulnerability of those dependent on fisheries for life and livelihood.
