The International Committee on New Integrated Climate Change Assessment Scenarios (ICONICS) has a series of webinars to discuss recent work on the Climate Change Scenarios Framework. ICONICS aims to organize the process of developing new socioeconomic scenarios to facilitate interdisciplinary research and assessment on climate change mitigation and adaptation.

Scenario Development

The scientific community has developed a thorough understanding of the climate system, specifically on elements such as the relationship between greenhouse gasses and global temperature. While there is evidence that these elements have been anthropogenic in nature, human activity is undoubtedly a highly unpredictable variable in determining climate change, considering how rapidly and suddenly lifestyle and policy can change, and the way technology and the economy continue to progress. Climate scientists examine data to perform projections that can help to determine what kind of future is in store for the Earth. Scenarios are used to help scientists understand how different variables including land use change, energy production, aerosol injection, and other radiative forcings of global temperature may interact in shifting the Earth’s climate. Scenarios are a way of standardizing thousands of data points to perform accurate climate projections. This has been a useful tool to make important decisions based on the scenarios presented from the intersection of data describing physical processes such as weather, climate, ocean, atmospheric, and land, and impactful human-driven processes such as population growth, economic advancement, energy, and emissions. 


ICONICS Inaugural Webinar Introduction

Speaker: Brian O’Neill (JCGRI)

Date aired: 22 February 2021

Brian O’Neill (JCGRI) presents the SSPs and RCP framework in the first tutorial of the inaugural ICONICS webinar held on 22 February 2021. Participants learned about the SSP-RCP scenario framework and the matrix architecture, SSP regional and sectoral extensions and available resources for learning about and working with the SSPs.

ICONICS Webinar on the Achievements and Needs of the Scenarios Framework

Speakers: Dr. Bas van Ruijven (IIASA), Dr. Tim Carter (SYKE)

Date aired: 6 April 2021

About: Dr. Bas van Ruijven (IIASA) and Dr. Tim Carter (SYKE) present and discuss the recommendations from the “Achievements and Needs of the Scenarios Framework” paper:…. Achievements and plans forward for the SSPs and RCPs based on the Achievements and Needs of the Scenarios Framework.

ICONICS Webinar Societal and Climate Change

Speakers: Dr. Kris Ebi (UW Global Change), Dr. Jana Sillmann (CICERO)

Date aired: 25 May 2021

About: This series focuses on societal and climate conditions. Dr. Kris Ebi from UW Global Change presents the consensus study on the US Global Change Research Needs and Opportunities for 2022-2031. Dr. Jana Sillmann from CICERO speaks about how event-based storylines can be used to better communicate risk.

ICONICS webinar “Producing a broader range of reference scenarios that include impacts and policy.”

Speakers: Tim Carter (SYKE), Elmar Kriegler (PIK), Franziska Piontek (PIK)

Date aired: 28 September 2021

About: Tim Carter, Research Professor at the Finnish Environment Institute (SYKE) introduces the topic, followed by Elmar Kriegler, Head of the Research Department “Transformation Pathways” at the Potsdam Institute for Climate Impact research (PIK) and Franziska Piontek, Senior Scientist at PIK, who both expand on examples, caveats, and advantages of integrated impacts and policy scenarios. Chaired/Moderated by Bas van Ruijven, International Institute for Applied Systems Analysis (IIASA).

ICONICS Webinar Updating the socioeconomic projections of the SSPs.

Speakers: Detlef van Vuuren (PBL), Samir K.C. (IIASA), Wolfgang Lutz (IIASA), Rob Dellink (OECD), Marian Leimbach (PIK)
