    The world’s glaciers are shrinking, with knock-on impacts for local communities. We need a better grasp of the hazards they leave behind.

    Intensive irrigation in India cools the land surface, but increases the moist heat stress in South Asia, according to an analysis of observational datasets and meteorological models.

    Where there is smoke, there are radiative feedbacks. With wildfires becoming a growing problem in the Anthropocene, we need to better understand the influence of fire on the climate system.

  • Comment |

    Underground smouldering fires resurfaced early in 2020, contributing to the unprecedented wildfires that tore through the Arctic this spring and summer. An international effort is needed to manage a changing fire regime in the vulnerable Arctic.

    Internal waves can relieve coral reef heat stress, according to an analysis that isolates the effect at different depths using a compilation of high-resolution temperature records.

    The European mega-heatwaves in 2003 and 2010 were intensified by torrents of hot air that were transported in from desiccated regions upwind, suggests an analysis of observations and reanalysis data together with a Lagrangian heat-tracking framework.

  • Comment |

    The climate of South and East Asia is affected by anthropogenic aerosols, but the magnitude of the aerosol imprint is not well known. As regional emissions are rapidly changing, potential related climate risks must be quantified.

    Wildfires are a natural part of many ecosystems, but they can become destructive and less predictable, especially when the system is perturbed. Human activities and climate change lead to interactions with fire dynamics that need our attention.

    Delivery of fossil carbon to the oceans strongly increased about 15 kyr after the onset of the Palaeocene–Eocene Thermal Maximum as a result of oxidation of sedimentary carbon, suggests an analysis of geochemical measurements with a biomarker mixing model.

    While anthropogenic influence on global climate is clear, human impact on the Southern Ocean has been difficult to pin down. A new detection and attribution study achieves just that.

    Rivers in the Western Siberian Lowland, the world’s largest peatland, play a significant role in the release of terrestrial carbon to the atmosphere, according to in situ measurements of carbon dioxide emissions from rivers.

    January 2018 was an unusually warm and wet month across the Western Alps, with widespread landslides at low elevations and massive snowfall higher up. This extreme month yields lessons for how mountain communities can prepare for a warmer future.

    Tall trees are more resilient to drought than short trees, suggests a comparison of the sensitivity of photosynthesis to soil moisture in Amazon forests.

    A comprehensive assessment of grounding-line migration rates around Antarctica, covering a third of the coast, suggests retreat in considerable portions of the continent, beyond the rates expected from adjustment following the Last Glacial Maximum.

    Satellite measurements indicate that Greenland's meltwater rivers are exporting one billion tons of sediment annually, a process that is controlled by the sliding rate of glaciers. This rate is nearly 10% of the fluvial sediment discharge to the ocean.

    Glaciers and ice sheets are retreating in response to climate warming. An analysis of drainage patterns of a huge glacier in Yukon, Canada shows that glacier retreat has led to a drastic change in the destination of its meltwater in spring 2016.

    The atmosphere can hold more water in a warming climate, which may lead to more extreme rainfall events. An analysis suggests that links ofrainfall extremes with daily temperature variations do not provide a reliable basis for projections.

    Arctic warming affects weather and climate thousands of miles to the south. Scientists are split on how large this effect is.

    Groundwater resources are directly affected by climate variability via precipitation, evapotranspiration and recharge. Analyses of US and India trends reveal that climate-induced pumping indirectly influences groundwater depletion as well.

  • Article |

    Glaciers have been retreating almost globally over the past century. An analysis using signal-to-noise ratio as a metric of individual glacier change reveals that glacier retreat constitutes categorical evidence for regional climate change.

    The clock is ticking for climate change mitigation. Geoengineering is gaining ground as an option, but it needs to be examined at a large scale to determine its effectiveness and associated risks.

  • Review Article |

    Extratropical storms contribute to precipitation, wind and temperature extremes. A synthesis of the influences of a changing climate on storm tracks reveals competing effects on meridional temperature gradients, which make projections difficult.

    Soil carbon stocks depend on inputs from decomposing vegetation and return to the atmosphere as CO2. Monitoring of carbon stocks in German alpine soils has shown large losses linked to climate change and a possible positive feedback loop.

  • Commentary |

    Some climate change impacts rise fast with little warming, and then taper off. To avoid diminishing incentives to reduce emissions and inadvertently slipping into a lower-welfare world, mitigation policy needs to be ambitious early on.

    In the United States, hurricanes have been causing more and more economic damage. A reanalysis of the disaster database using a statistical method that accounts for improvements in resilience opens the possibility that climate change has played a role.

    Decomposition of soil organic matter could be an important positive feedback to climate change. Geochemical properties of soils can help determine what fraction of soil carbon may be protected from climate-induced decomposition.
