  • Climate change is increasing ocean temperature, particularly in the surface waters. Here the authors show that accelerated surface warming in the North Pacific in the past decade is driven by shoaling of the ocean mixed layer with some dampening by increased latent heat loss from the ocean.

  • Addressing the consequences of climate change requires political attention and leadership. However, this study shows that apart from Green parties, political parties do not increase their attention to environmental issues following extreme weather events.

  • Most of the meteorites on the Earth’s surface are found in Antarctica. Here the authors show that ~5,000 meteorites become inaccessible per year as they melt into the ice due to climate change.

  • The authors conduct a systematic literature review on renewable energy expansion and biodiversity. Comparing renewable energy siting maps with the ranges of two threatened species under future climates, they highlight the potential conflict and need for consideration of climate-change-driven range shifts.

  • International trade of used vehicles lacks regulation on emissions standards. This study shows that vehicles exported from Great Britain generate substantially higher carbon and pollution emissions than scrapped or on-road vehicles.

  • The authors investigate the impacts of excluding ecosystem data from Russian stations in the Arctic. While the current network of Arctic stations is already biased, the exclusion of Russian stations lowers representativeness and creates further biases that can rival end-of-century climate change shifts.

  • The increase in atmospheric methane has been accelerating since 2007, and identifying drivers is critical for climate mitigation. In this study, the authors show that the expansion of rice cultivation in Africa accounts for 7% of rising emissions.

  • Rice paddies are a source of the potent greenhouse gas methane. The authors demonstrate that a rice variety containing naturally lost function in the gene GS3 has reduced allocation of photosynthates to roots, which results in a reduction of methane emissions during growth.

  • .Observations of glacier response to climate changes prior to the satellite era are sparse. Here the authors use historical aerial photographs to document change in peripheral glaciers in Greenland since 1890, providing enhanced confidence that recent changes are unprecedented on a century timescale.

  • Upslope migration is a recognized climate change response, but which traits support this migration is unclear. The authors use a global dataset of 807 insect species—flying and non-flying—to show that lagging upslope migration in terrestrial animals may be linked to oxygen demands.

  • Climate-induced extreme events could disrupt the operation of ports globally, which could affect maritime transport, trade and supply chains. The authors estimate wider impact on the trade and economic activities across different sectors, finding that globally large economic cost is at-risk.

  • Atmospheric methane concentrations are increasing and a process-based model now estimates greater methane emissions from wetlands since 2007 than previous studies. Substantial increases in 2020 and 2021 contributed to record-high growth rates in the atmospheric methane burden.

  • Natural gas has been seen as a bridge in the move from fossil fuels to cleaner energy. This work presents UK longitudinal survey data showing climate change beliefs increasingly diminish public support for natural gas.

  • How the shelf ocean around Antarctica changes with warming is not well known. Here, the authors show that a projected increase in El Niño–Southern Oscillation variability accelerates warming of the Antarctic shelf ocean but slows warming around the sea ice edges, thus influencing ice melt.

  • The Hunga Tonga–Hunga Ha’apai eruption in January 2022 injected large amounts of water vapour into the atmosphere. Here, the authors show that this can cause additional warming over the next years, which increases the likelihood of exceeding 1.5 °C warming over a short time period.

  • The adoption of some climate policies can facilitate the subsequent adoption of other policies, which is referred to as policy sequencing. Across sectors and countries, policy sequences often play an important role in the adoption and stringency of carbon pricing.

  • The degree to which aerosols influence surface temperatures is not well understood. Here, the authors argue that reducing the uncertainties in the climate response to aerosol forcing is one of the key challenges to reduce overall uncertainties of warming projections.

  • A reliable and consistent inventory is important for the international community to track and promote the progress of climate finance. A machine learning classifier reveals that the current framework may overestimate the actual number of bilateral climate finance projects.
