Climate scientist Julie Kalansky discusses how drought in California and Nevada is a common occurrence, with the attendant water restrictions and threat of severe wildfires bringing the reality of climate change into sharp focus. Future climate projections for the region suggest a trend toward more extremes, including more severe and prolonged drought as well as exceptionally wet years. Learn about the science of drought and how the Scripps-based California Nevada Climate Applications (CNAP) program works to provide drought tracking and early warning in support of drought preparedness and resilience in the face of a changing climate.
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.
With unchecked emissions of climate pollutants, there is a 50% probability for the planetary warming to cross the so-called dangerous threshold of 20C by 2050; and there is at least a 5% probability the warming can exceed a catastrophic 60C in about 80+ years.
Climate scientists study more than Earth’s changing climate. They are an integral part of coming up with solutions for both mitigating and adapting to these human-caused changes. Join world renowned scientist Ram Ramanathan for insight into a multifaceted education program, Bending the Curve, which inspires action on climate solutions. The groundbreaking program is offered at all University of California campuses and internationally. Learn how he and colleagues around the world are educating students at every level to become climate warriors.
People with allergies know that daily weather determines symptoms and that symptoms vary by season. Dr. Katherine Gundling, an allergy and immunology specialist at UCSF, looks at how the warming of our planet might affect allergic respiratory disease. What is emerging from data collected at pollen counting stations around the world is that the length of pollen season is increasing, starting earlier and ending later, especially in higher latitude and higher elevations. As temperatures increase pollen concentrations rise. And increasing temperature may also cause pollen to be more potent.
There are similar indicators that climate change is increasing mold growth. Of particular concern are indoor molds that propagate in wet environments. As sea levels rise and flooding and humidity increase, so too does mold exposure which can cause severe asthma reactions, especially in children who are more vulnerable.
The good news is that we know what to do. Climate change solutions are also solutions to improving health disparities and allergic respiratory disease.
New weather patterns and events are causing concern but how do we know these changes are caused by human activity? Climate scientists are looking at trends over time to determine our impact on the planet.
Prather discusses recent CAICE studies aimed at advancing our understanding of how the oceans influence human and planetary health including novel experiments being conducted in a unique ocean-atmosphere simulator.
