The use of cross-sectoral strategies, such as the exchange of waste energy through co-location of industry, business and residential areas, is shown to be effective for greenhouse gas and particulate mitigation in this study of 637 Chinese cities.
Hydropower represents the largest source of renewable energy currently available, yet its potential provision remains poorly characterized. Gernaat et al. present a high-resolution global assessment of technical and economic hydropower potential based on an analysis of over 3.8 million individual locations.
Ecosystem accounts quantify trade-offs between the economy and the environment. Here, the authors apply this approach to a regional case study of native forest use to show how it can be used to inform policy about complex land management decisions.
Changing climates are outpacing some components of our food systems. Risk assessments need to account for these rates of change. Assessing risk transmission mechanisms across sectors and international boundaries and coordinating policies across governments are key steps in addressing this challenge.
Warm conditions in the Arctic Ocean have been linked to cold mid-latitude winters. Observations and simulations suggest that warm Arctic anomalies lead to a dip in CO2 uptake capacity in North American ecosystems and to low crop productivity.
