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.
