Reengineering Resilience: Bio-Resilience Bonds For Financing Microbial Infrastructure And Climate Equity, Reece Buckley

COP30

This policy proposal introduces Bio-Resilience Bonds (BRBs), a performance-based financial instrument designed to monetise microbial ecosystem services as measurable climate infrastructure. Microbial ecosystems are crucial for climate resilience, yet they are often overlooked in mainstream adaptation f inance frameworks. Their ability to regulate carbon and nitrogen cycles, reduce methane emissions and enhance soil and water stability (Delgado-Baquerizo et al., 2016) makes them essential assets for climate mitigation and adaptation. With global adaptation needs exceeding £2.7 trillion (UNEP, 2024), this oversight indicates a systemic failure to recognise biology as a form of infrastructure. BRBs transform microbial outputs into localised key performance …

Democratic Reliance On Non-State Actors For Climate Change: How Promotion Of Subnational And Non-State Actors Mend The Gap To National Mitigation Outcomes., Yezen Nael Said

COP30

Representative democracies face structural and political challenges that hinder the implementation of robust climate action. Short electoral cycles discourage long-term investments in mitigation, while institutional inertia and political polarization stall responsive policymaking. Interest group influence further weakens reform efforts. These limitations are compounded by the public's tendency to prioritize immediate, tangible benefits over long-term environmental gains, as illustrated by voter resistance to proactive climate taxation in Norway and Germany’s sluggish implementation of Paris Agreement targets. National climate strategies must therefore be reinforced by subnational and non-state actors. Cities, in particular, can serve as engines of innovation and implementation, leveraging localized …

Mcmc-Net: Accelerating Markov Chain Monte Carlo With Neural Networks For Inverse Problems, Anuj Abhishek

Faculty Scholarship

In many computational problems, using the Markov Chain Monte Carlo (MCMC) can be prohibitively time-consuming. We propose MCMC-Net, a simple yet efficient way to accelerate MCMC via neural networks. The key idea of our approach is to substitute the true likelihood function of the MCMC method with a neural operator based surrogate. We extensively evaluate the accuracy and speedup of our method on three different partial differential equation-based inverse problems where likelihood computations are computationally expensive, namely electrical impedance tomography, diffuse optical tomography, and quantitative photoacoustic tomography. MCMC-Net performs similar to the classical likelihood counterpart but with a significant speedup. …
