Reducing Mortality in A Future with Extreme Heat: Advancing Research on Public Health, Climate and Climate Intervention for Extreme Temperature Resilience


As climate conditions grow ever more dangerous, policymakers and people around the world have begun to consider approaches to protecting communities and people. This special invitation-only discussion will feature experts on medicine, climate, technology and society on protecting society from extreme heat moderated by Jeff Goodell, New York Times Best Selling Author of The Heat Will Kill You First: Life and Death on a Scorched Planet and How to Cool the Planet.

Reducing mortality in a future of extreme heat requires better projections of climate, regional heat waves and heat mortality than we have today. It requires innovation across medicine, public health, infrastructure and policy. It also involves research and evaluation of approaches to reduce humid heat impacts regionally or globally, sometimes called climate intervention.  We are pleased to host a very special two part panel event that will explore scientific and societal considerations for local response to extreme heat and for evaluating the potential for regional and global climate interventions to reduce extreme heat impacts and risks in the future.

AGU Talks and Oral Sessions

Data Sets and Potential Experiments for Assessing High Altitude Climate Interventions

SilverLining Grantee | Session: A12C - Exploring the Interplay of Weather Modification and Climate Intervention: Modeling, Observations, and Field Campaigns I Oral

As interest grows in rapid climate interventions to combat global warming, there is a focus on high-altitude strategies like cirrus cloud thinning (CT) and stratospheric aerosol injection (SAI). This event reviews the tools and data available to assess these approaches. Previous NASA missions, such as SUCCESS and SONEX, have gathered valuable data on how aircraft emissions affect cloud formation, which can help develop strategies to reduce contrail formation. Additional NASA studies have enhanced techniques for tracking aircraft emissions, which is relevant for small-scale experiments in releasing reflective aerosols. Insights from volcanic plume studies provide natural parallels to SAI. Proposed lab studies aim to test aerosol formation in simulated environments, helping to refine models and evaluate the effectiveness of these high-altitude interventions in mitigating climate impacts.

Chasing Low Clouds Over the Oceans: Unique Experiential Learning in the Field

SilverLining Grantee | Session: A32A - Atmospheric Sciences 2024 Fellows | Oral

This presentation highlights the critical role of field campaigns in understanding how clouds influence the climate. Low clouds over the oceans are key to regulating Earth's climate, and changes to them—whether due to global warming or potential marine cloud brightening—could have significant climate impacts. To unravel the complex interactions and feedbacks that govern their behavior, a blend of models, observations, and hands-on fieldwork is essential. Field campaigns offer a unique opportunity, not only to gather crucial data but also to foster collaboration and mentorship among early-career scientists, encouraging the exchange of diverse ideas and insights to advance climate science.
