Some Highlights and Insights of the CMIP6 Earth System Modeling Simulations for Station Scientists Discussing the Latest IPCC Reports

The Intergovernmental Panel on Climate Change (IPCC) is hard at work writing new reports to share new research findings in climate science for the world's governments and for the public. In 2018, the IPCC released the Special Report on Global Warming of 1.5ºC that presents "the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways." In 2019, the IPCC released the Special Report on Climate Change and Land to discuss "climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems." In 2021, the IPCC plans to publish the Sixth Assessment Report (AR6) on Climate Change that will include four volumes: one each from Working Groups 1, 2, and 3 and a Synthesis Report in 2022. To provide predictions of climate change and its impacts on society and natural systems, scientists use state-of-the-science Earth System Models as their the primary tools. In this talk, we will discuss the latest set of these models being used in the 6th Coupled Model Intercomparison Project (CMIP6) and how they have developed since the AR5 finished in 2014. We will try to answer the following questions:

• What new science is represented in these models?
• What new observations are helping us test them?, and
• What new insights might be gained from using these models?

Overall, the goal is for you to become more familiar with the details of the updated models and simulations and how best to discuss new scientific results with the public.
