Dryland ecosystems become more sensitive to water stress after disturbances

Nature Climate Change, Published online: 02 January 2025; doi:10.1038/s41558-024-02203-y Climate-sensitive disturbances impact ecosystem productivity and carbon uptake. We found that the sensitivity of ecosystem productivity to disturbances differs between regions, with dryland ecosystems becoming more sensitive to water stress after disturbances, whereas wet regions become less sensitive. On average, ecosystem sensitivity requires approximately five years…

Navigating the technical dialogue of the first global stocktake from process to findings

Nature Climate Change, Published online: 30 December 2024; doi:10.1038/s41558-024-02220-x The first global stocktake marks an important step in enabling Parties to the Paris Agreement to enhance their climate actions and support with the aim of achieving long-term goals. Two co-facilitators of the technical dialogue discuss the process, findings, relationship with political outcomes and implications for…

Actions before agreement

Nature Climate Change, Published online: 23 December 2024; doi:10.1038/s41558-024-02223-8 The recent COP29 barely reached a new climate finance target that leaves all parties wholeheartedly satisfied. However, even without perfect agreement, climate actions should not be delayed.

Climate-induced divergence of song

Nature Climate Change, Published online: 20 December 2024; doi:10.1038/s41558-024-02222-9 Vocal communication is essential for information transmission in many species, such as that related to mating opportunities or predator presence. Recent research revealing how phenotypic changes brought about by a changing climate may influence vocal communication raises some serious concerns for conservation management.

Rethinking microbial carbon use efficiency in soil models

Nature Climate Change, Published online: 19 December 2024; doi:10.1038/s41558-024-02217-6 Soil models include a key parameter known as carbon use efficiency, which impacts estimates of global carbon storage by determining the flow of carbon into soil pools versus the atmosphere. Microbial-explicit versions of these models are due for an update that recasts carbon use efficiency as…

Humid heat exceeds human tolerance limits and causes mass mortality

Nature Climate Change, Published online: 18 December 2024; doi:10.1038/s41558-024-02215-8 The hottest boreal summer on record has driven widespread humid heat mortality across every continent of the Northern Hemisphere. With critical physiological limits to human heat tolerance drawing ever closer, this Comment highlights the urgent need to limit further climate warming and emphasizes the adaptation challenge…

Tax carbon cautiously for sub-Saharan Africa

Nature Climate Change, Published online: 13 December 2024; doi:10.1038/s41558-024-02213-w A carbon tax will not curb current emissions in sub-Saharan Africa and is unlikely to prevent future carbon lock-in effects. Meanwhile, a carbon tax could hit the poor in this region, thus the international community should be careful in pushing sub-Saharan Africa towards carbon taxation.
