Local fishermen, surfers, and beachgoers know that ocean temperatures off California’s coast vary, often expectedly, and sometimes unexpectedly – you know, when the water is suddenly below sixty-degrees in the middle of an August heatwave! Join Scripps oceanographer and remote observation vehicle expert Katherine Zaba to learn how scientists deploy innovative ocean technology and just how these ingeniously built sentinels work to monitor and help us understand ocean warming phenomena, like marine heatwaves, the well-known “blob” and El Niño events, that affect not only California’s coastline, but our entire climate regime.
California’s unique geography, with some of the continent’s highest mountains situated close to the broad expanse of the Pacific Ocean helps make California’s precipitation regime the most volatile in the country. This volatility, characterized by large natural swings between drought and extremely rainy years make water resource management in California notoriously difficult. Global climate change is expected to exacerbate the volatility by decreasing the frequency of regional precipitation while increasing its intensity. Join meteorologist Alexander Gershunov to learn how he and other researchers quantify and analyze this volatility to understand the mechanisms behind these changes, and project their anticipated impacts on California.
Jeff Bowman is a biological oceanographer who studies marine microbial communities. In this presentation at the Birch Aquarium at Scripps Institution of Oceanography he describes his group’s work in the Arctic as they seek to understand the ecological implications of changing sea ice conditions.
They are also preparing to participate in the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) Expedition, an unprecedented multi-national effort to study the high Arctic across a complete seasonal cycle.
“What we do in my group is we zoom in on the aerosols.”
Vicki Grassian and her team look at aerosols at a microscopic level to determine their impact on our health and our climate. Aerosols can be mineral dust and sea spray from the ocean or created by human activity or stem from any number of sources. They can travel across the globe impacting people, animals, and the planet in their wake.
Grassian’s work seeks to understand how aerosols and other gases not only affect us but how we might harness them for solar geoengineering.
“When you talk about diversity of the soil, human beings we carry our soil with us. And we give that a very fancy term which is all the rage these days which is ‘microbiome.’ And as we see microbes diminishing in the soil, we are also seeing the same things happen in ourselves,” says Kelli Gray-Meisner, RDN.
Super blooms, extreme weather, fires, insects, and human health, these seemingly separate things impact each other – for better or worse. Join a panel of experts as they tease out the relationships being built and destroyed by climate change. They also share how we as individuals can work to limit negative impacts and create positive outcomes.
