    Please join us for the annual Keeling lecture in honor of Scripps Professor Charles David Keeling's life and invaluable contributions to climate science and the Scripps Institution of Oceanography. Tereza Cavazos's will present an overview of relevant climate drivers shared in the US-Mexico western border region, as well as their possible changes and impacts. From extreme weather to droughts, from the monsoon rains to the jet stream and El Niño events, these variations see no artificial borders; however, adaptation to climate change poses major challenges particularly south of the border.

    Coastal regions are susceptible to a host of threats to the natural environment and our quality of life as a result of climate change. Our beaches and coastal bluffs are being eroded by ocean storms and sea level rise, ongoing drought leaves us vulnerable to wildfires and habitat and wildlife loss, and our dependence on water from distant sources puts us at risk for severe water restrictions. Although climate adaptation and resilience planning already are underway in many communities, the threats associated with climate change make it increasingly important to design these efforts in ways that bring scientists, planners, practitioners, and community representatives together in planning processes. An expert panel is presenting how a cross-jurisdictional, interdisciplinary, collaborative approach leads to science-based and cost-effective strategies for building resilience in the face of climate change.

    Collapsing ice shelves and calving of large icebergs in Greenland and Antarctica have recently become major drivers of sea level rise. The rapidity of these changes has come as a surprise, revealing major gaps in our understanding of how ice sheets respond to a changing climate. To a large extent, these gaps are due to the lack of measurements from the marine edge of glaciers - the Achilles' heel of glaciers. For over a decade, since the glaciers in Greenland began their retreat, Fiammetta Straneo and her group at Scripps Institution of Oceanography have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland using helicopters, icebreakers, fishing vessels, and autonomous vehicles.
