The African Union Commission (AUC) has launched a decisive effort to bridge the gap between scientific research and policy action, inaugurating the first-ever Symposium of the Africa Science and Technology Advisory Group on Disaster Risk Reduction in Victoria Falls, Zimbabwe. 

Accelerating Climate Action in Unfavourable Local Contexts: the Role of Policy Entrepreneurship

Accelerating Climate Action in Unfavourable Local Contexts: the Role of Policy Entrepreneurship

Local authorities are expected to lead on net-zero delivery, irrespective of their capacity to do so. This paper addresses the extent to which they can act on climate change and how policy entrepreneurs can exert agency.

Finnish experts’ perceptions of IPBES operating principles – Synergies and tensions between the multiple evidence base and credibility, policy relevance and legitimacy

Finnish experts’ perceptions of IPBES operating principles – Synergies and tensions between the multiple evidence base and credibility, policy relevance and legitimacy

Intergovernmental science policy organizations assess and mediate knowledge for decision makers, especially their member governments. The Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) is known as a trailblazer in acknowledging plural knowledge systems because of the multiple evidence base approach it has adopted, which has challenged the older operating principles of credibility, policy relevance, and legitimacy. This paper juxtaposes those principles and the multiple evidence base to study their context-sensitive synergies and tensions, based on experts’ perceptions of IPBES operations.

Glacier Intervention Research Isn't Just for Glaciologists

Prospects for mitigating sea level rise by slowing flows of glacial ice into the ocean are worthy of research, but this work must involve all rights holders and stakeholders.

Step Up Geoengineering Research, EU Science Advisers Recommend

Step Up Geoengineering Research, EU Science Advisers Recommend

The EU's panel of science advisers has called for more research into geoengineering, to understand the feasibility - and potential risks - of trying to block out the sun to cool a warming earth. 

State Capacity and Varieties of Climate Policy

State Capacity and Varieties of Climate Policy

Multiple policy mechanisms exist to create climate policy. In this comment, the authors discuss the institution capacity and fiscal space that shape national policies around sticks and carrots mechanisms.

A Multi-model Assessment of Inequality and Climate Change

A Multi-model Assessment of Inequality and Climate Change

Climate change and economic inequality are critical issues, and we still lack understanding of the interaction between them. Multi-model analysis shows how climate policies compatible with the goals of the Paris Agreement, including revenue-redistribution schemes, can reduce inequality-particularly in the short and medium terms.
