The modern food industry is reshaping society and contributing to global warming. Mitigation efforts at different levels are needed to promote environmental and human health.

Although the role of the human diet in climate change has been widely acknowledged, current practices fail to capture its realistic effect on warming. In this Analysis, Ivanovich et al. develop a global food consumption emission inventory and estimate the associated future climate impact using a reduced-complexity climate model.

The authors summarize the underappreciated role of climate change in amplifying human–wildlife conflict. They synthesize evidence of climate-related conflicts and introduce a framework highlighting the environmental, ecological and sociopolitical pathways linking climate change to conflict outcomes.

An EU embargo on Russian fossil fuels would lead to a rapid decrease in fossil fuel combustion, GHG emissions reductions and potential economic losses. This analysis quantifies such effects, while also demonstrating how demand-side responses could offset the negative shock.

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.

Warming reduces the greenhouse gas sink of pristine wetlands. Here the authors show that carbon dioxide emissions increase in cryptogam sites at higher latitudes, while methane and nitrous oxide emissions are enhanced in vascular-plant-dominated permafrost wetlands.

Using data on oxygen variability taken from 32 representative reef sites, the authors show that hypoxia is already common. Under future scenarios of ocean warming and deoxygenation, the duration, intensity and severity of hypoxia will increase, with nearly one-third of reefs experiencing severe hypoxia.

The authors investigate relationships between various soil stressors that exceed critical thresholds and the maintenance of ecosystem services. They show that multiple stressors crossing a high-level threshold reduces soil functioning and can be consistently used to predict ecosystem functioning.

Indigenous and Western knowledge ethically combined is uniquely suited to address ongoing climate challenges. To build an environment where Western and Indigenous knowledge systems thrive, funding institutions must value co-production of knowledge and be available to Indigenous experts.
