The background shows a blurred peatland landscape with trees and water. Below the title is a chart illustrating a marginal abatement cost curve (MACC). The vertical axis shows cost-effectiveness in dollars per ton of CO₂ equivalent, ranging from negative values (cost savings) up to very high positive costs. The horizontal axis shows greenhouse gas mitigation potential in kilotons of CO₂ equivalent. Several bars extend across the chart. On the left, smaller bars fall below zero, indicating low-cost or cost-saving mitigation measures such as improved breeding, fertility, and feed efficiency. Toward the middle, additional measures with modest costs appear. On the right, larger bars rise sharply above zero, representing higher-cost interventions like covering lagoons, dietary changes, and advanced technologies. A horizontal line marks the “Social Cost of Carbon,” indicating a benchmark for cost-effectiveness. The figure caption notes that this is an example MACC for UK dairy mitigation measures. The “WET HORIZONS” logo appears in the bottom right corner.
Slide titled “Assessing modelled methane emissions over northern wetlands by the JULES–HIMMELI model,” followed by a list of authors. The graphic explains how methane emissions are simulated by combining the JULES land surface model with the HIMMELI methane model. A diagram shows JULES providing inputs such as leaf area index, water table depth, soil temperature, and soil respiration. These inputs feed into the HIMMELI model, which simulates methane production, oxidation, and transport through processes such as plant transport, diffusion, and ebullition within peat layers, alongside oxygen and carbon dioxide interactions. The background image shows a wetland landscape with water and vegetation, and the Wet Horizons logo appears at the bottom.
