Geosciences are one of the least gender-diverse fields, with women representing ~33% and ~39% of those employed in the USA and UK, respectively. Institutionalized and incentivized culturally responsive mentorship through establishment of career investors offers an accelerated path toward transforming geoscience culture and leadership.

Engineered nanomaterials (ENMs), intentionally synthesized materials with sizes less than 100 nm in at least one dimension, have numerous potential environmental applications, such as pollution remediation and water treatment. However, concerns regarding their potential health and environmental impacts have been raised. In this Review, we assess the opportunities of ENMs in environmental applications versus their potential public and environmental health risks, focusing on water treatment and reuse, and identify strategies for their responsible use. Life-cycle analyses indicate that the highest potential environmental and health impacts of ENMs used in commercial products are associated with production rather than incidental release during use. Typically, the detected or predicted ENM concentrations are 1 to 4 orders of magnitude lower than their respective predicted no-effect concentrations. In addition, ENMs often undergo passivating transformations, such as agglomeration and oxidation, reducing risks after release. Therefore, the environmental and health risks of ENMs are relatively low. However, some point sources under extreme scenarios, such as sewage effluent, can potentially increase localized risks. Adopting green chemistry and immobilization strategies can further limit the release of ENMs, minimizing their potential discharge into the environment. Such strategies to reduce toxicity and exposure enable sustainable application of ENMs, such that the environmental benefits could outweigh the risks if managed properly. Engineered nanomaterials (ENMs) have numerous environmental applications, such as in water treatment and reuse. This Review explores the trade-offs between the risks and benefits of environmental ENMs, and highlights that the environmental and health risks of ENMs are relatively low when used responsibly.

Terrestrial ecosystems release ~106–130 PgC yr–1 into the atmosphere through respiration, counterbalancing photosynthetic carbon uptake and determining the strength of the land carbon sink. The effect of anthropogenic warming on the land carbon sink will depend on the temperature response of respiration. In this Review, we explore the relationships between temperature and ecosystem respiration from experimental and observational data at leaf, microbial, ecosystem and global scales. Contrary to the assumed monotonic increase in respiration with increasing temperature derived from Earth system models, empirical findings indicate a unimodal temperature response with a peak in respiration at an optimal temperature (Topt). This unimodality is observed across a range of organization levels with Topt values of 40–60 °C at the leaf and plant level, 11–46 °C at a microbial level and 6.5–33.3 °C at the global scale. Various mechanisms contribute to this unimodal pattern including enzyme deactivation, the thermodynamics of enzyme-catalysed reactions and changes in temperature-dependent factors such as soil moisture, nutrient availability and vegetation physiology. Incorporating the unimodality of these observed temperature responses of ecosystem respiration into Earth system models could facilitate attribution studies to identify the mechanisms responsible for the peaked response and increase the accuracy of carbon sequestration predictions. The future of the land carbon sink depends on the temperature response of ecosystem respiration. This Review explores observational and experimental evidence for a unimodal temperature response of respiration and the implications for carbon sequestration predictions.

The Kunming–Montreal Global Biodiversity Framework (KM-GBF) provides a major impetus for the restoration and conservation of blue carbon ecosystems to address the biodiversity and climate crises. In this Perspective, we translate the KM-GBF targets for blue carbon ecosystems into quantitative metrics, outline action that must be taken to achieve these goals and quantify the associated climate benefits. To achieve the KM-GBF targets, net mangrove, saltmarsh and seagrass losses of 187–190 km2, 76–126 km2 and 3,068–3,597 km2, respectively, must be avoided annually from 2030 onwards and 23,693–24,369 km2, 10,467–17,296 km2 and 90,601–106,215 km2 of these ecosystems must be restored. Achieving the KM-GBF targets would contribute 2.8% of the reduction of carbon emissions needed to limit anthropogenic warming to 2 °C by 2030. However, the cost of achieving the targets (US$520.1 billion yr–1) far exceeds the amount pledged ($200 billion yr–1) for all ecosystems. Thus, research is needed to develop cost-effective restoration and conservation technologies, along with innovative financial models to incentivize investments in nature. Additionally, blue carbon actions must be embedded within National Biodiversity Strategies and Action Plans to ensure that the targets are met. Degradation and loss of blue carbon ecosystems contributes to climate change, weakens coastal protection and threatens biodiversity. This Perspective outlines the actions required to achieve goals to restore and protect these ecosystems.
