Efficient nitrogen management as a win-win strategy for air quality, health, and climate

Reactive nitrogen (Nr) management links climate policy, air quality and food production, yet its combined impacts remain poorly quantified. Here, we conduct ensemble simulations with two global climate models, Goddard Institute for Space Studies (GISS) and Community Earth System...

Quantifying the role of nitrogen in achieving global Sustainable Development Goals

Abstract Achieving the 2030 Sustainable Development Goals (SDGs) requires balancing well-being with environmental protection, yet the role of nitrogen across these goals remains poorly understood. Here, we show how dietary nitrogen intake and nitrogen release to air and water are...

Global trade-offs between consumption, carbon prices and equity

As the remaining carbon budget continues to dwindle, economic growth strains efforts to limit global warming to 1.5 °C. Reducing unnecessary production and consumption in high-income regions and among the wealthy, and organising production more around human needs and human well-b...

Reduced Complexity Model Intercomparison Project phase 3: experimental protocol for coordinated constraining and evaluation of reduced-complexity models

Abstract. Reduced-Complexity Models (RCMs) are a critical tool for synthesising climate science knowledge and providing climate projections for a wide range of emissions scenarios. The Reduced-Complexity Model Intercomparison Project (RCMIP) provides a framework for the coordinat...

Region-specific infosheets on protected area expansion priorities

Infosheets for protected area expansionThis repository contains 2-page infosheets summarizing some of the key findings from the NaturaConnect pan-European prioritization work. There we identify the opportunities and benefits of expansions of strict and conventional protection. Th...
