ScenarioMIP-CMIP7 IAM quantification: Harmonized and Infilled Emissions and Climate Outcomes for Marker Scenarios

Unofficial AI-generated summary based on the public title and abstract. Not an official translation.

🔬研究者:Provides harmonized emissions data for climate modeling and integrated assessment, enabling consistent multi-model comparisons.

🏢実務担当者:Useful for corporate climate scenario analysis and transition risk assessment, though data are preliminary.

🏛政策担当者:Informs national and global climate policy by providing benchmark emissions pathways for mitigation targets.

This is a pre-release of the harmonized ScenarioMIP emissions data. Please refer to the Rules for data use and data sharing of the IAM ScenarioMIP Data at https://scenariomip.apps.ece.iiasa.ac.at. Harmonized Emissions of the IAM ScenarioMIP projections for CMIP7 ScenarioMIP-CMIP7 consists of alternative plausible futures including quantified emissions and land use projections. The primary objectives of ScenarioMIP are to: Facilitate integrated research leading to a better understanding of the physical climate system consequences of future scenarios and their impact on natural and social systems, including adaptation and mitigation considerations. Provide a basis for addressing targeted science questions about the climate effects of aspects of forcing relevant to scenario-based research. Provide a basis for various international efforts that target improved methods to quantify projection uncertainties based on multi-model ensembles. ScenarioMIP is part of the Coupled Model Intercomparison Project organised by the World Climate Research Programme, and integrates research across the climate science, integrated assessment modeling (IAM), mitigation, and impacts, adaptation and vulnerability (IAV) communities. Seven IAM teams participated in the scenario development process. Each scenario has been implemented with multiple IAMs, and a marker scenario was selected from the available model interpretations. The current pre-release comprises the harmonized emissions of the marker scenarios only. Harmonized emissions of additional non-marker quantifications will follow. This pre-release hosts limited data, with the publication of more data variables to follow. The available data are the emissions variables that have gone into the climate emulator MAGICC and its climate outcomes. The reported emissions variables are harmonized to CMIP7 historical emissions, and consistent with CMIP7 earth system model forcings: GHG concentrations and gridded emissions, as available on the Earth System Grid Federation (see input4MIPs: https://input4mips-cvs.readthedocs.io/en/latest/).
