This workshop will provide a forum to continue discussion about ways that the CEDAR community might contribute to global efforts to address climate change. Such efforts could include whole atmosphere studies of climate change processes; contributions by the CEDAR community to national and international climate assessment processes; strategies to reduce uncertainties in observations to facilitate their use for longer-term comparisons; identification of aeronomy data sets and techniques that can also provide tropospheric information; and steps that our scientific community can take to mitigate climate change, in our conferences and other practices. We welcome participation from the tropospheric climate community, as well as the middle and upper atmospheric research community, to discuss further ways that our communities might collaborate to advance knowledge of climate science. We also welcome discussion relating to climate impacts, equity, and justice; as well as strategies for mitigating and adapting to climate change, promoting civic engagement, and for communicating climate science in educational settings and to the public.

Session Format:

We plan that this workshop will be a mixture of presentations with interactive time for questions, and more general discussion on topics related to CEDAR and climate change.

We also plan to hold this workshop using a hybrid format to facilitate interdisciplinary interaction with potential speakers from outside the CEDAR community; to include more members of the international community and to enable participation of those not able to travel to the CEDAR in-person meeting for a variety of reasons.


The recent release of major climate assessments, including reports from the Intergovernmental Panel on Climate Change (IPCC), underscores the urgency of addressing climate change. The 2023 IPCC synthesis assessment warns that “Climate change is a threat to human well-being and planetary health (very high confidence). There is a rapidly closing window of opportunity to secure a liveable and sustainable future for all (very high confidence).” The report further explains that “Rapid and far-reaching transitions across all sectors and systems are necessary to achieve deep and sustained emissions reductions and secure a liveable and sustainable future for all. These system transitions involve a significant upscaling of a wide portfolio of mitigation and adaptation options. Feasible, effective, and low-cost options for mitigation and adaptation are already available, with differences across systems and regions. (high confidence),” and that “Prioritising equity, climate justice, social justice, inclusion and just transition processes can enable adaptation and ambitious mitigation actions and climate resilient development.” In summary, “The choices and actions implemented in this decade will have impacts now and for thousands of years (high confidence).” [IPCC 2023 AR6 Synthesis Report;]
