New climate scenario framework implementation in the GCAM integrated assessment model

This report has various objectives: (i) to provide an overview of the climate Integrated Assessment approach; (ii) to describe the Global Climate Assessment Model (GCAM); (iii) to outline the new IPCC scenario framework represented by the Shared Socio-economic Pathways (SSPs) and the Representative Concentration Pathways (RCPs); and (iv) to document the implementation of the new scenario framework in version 3.1 of the GCAM

A simple formula for the social cost of carbon

The social cost of carbon (SCC), commonly referred to as the carbon price, is the monetized damage from emitting one unit of CO2 to the atmosphere. The SCC is typically obtained from large-scale computational Integrated Assessment Models (IAMs) that consolidate interdisciplinary climate research inputs to obtain a carbon price  estimate relevant for policy-making…

Consistent assessments of pathways toward sustainable development and climate stabilization

This study quantitatively assesses some alternative scenarios using integrated assessment models, and provides several indicators relating to sustainable development and climate change, such as indicators of income (per capita GDP), poverty, water stress, food access, sustainable energy use, energy security, and ocean acidification, with high consistencies among the indicators within a scenario.

The “Doomsday” Effect in Climate Policies

Despite growing scientific evidence that passing a 2°C temperature increase may trigger tipping points in climate dynamics, most Integrated Assessment Models (IAM) based on Cost Benefit Analysis (CBA) with smooth quadratic damage functions are unable to account for the possibility of strong increase in climate damage…
