Unfold

Millions of people plan to make online purchases today for deals on Cyber Monday. In this encore episode of Unfold, you'll hear how impulse buying, fast shipping and returns can all lead to a higher carbon footprint. Miguel Jaller with the UC Davis Institute of Transportation Studies will unfold all the complexities of e-commerce.

In this episode:

Miguel Jaller, Co-director of the Sustainable Freight Research Center at the UC Davis Institute of Transportation Studies

Unfold travels to Kenya, where climate change is threatening a way of life for pastoralists. Climate change is driving families deeper into poverty. When drought hits, men travel for weeks in search of water and greener pastures for their livestock herds. The women and children are left behind with no stable source of food or income. UC Davis agricultural economists are researching the pairing of two intervention programs, including a type of climate insurance policy, to keep these vulnerable populations from falling so deep into poverty that they have no way to recover.

In this episode: 

Michael Carter, professor of agricultural and resource economics, and director of the Feed the Future Innovation Lab for Markets, Risk and Resilience at UC Davis, with research in Kenya funded by USAID.

In California, 40 percent of greenhouse gas emissions comes from transportation. Emissions from this sector will make it difficult to meet the state’s 2030 climate goals. There is a myriad of solutions: electric vehicles, public transportation, ride share, e-scooters and more. But people’s behaviors and habits as well as bad land-use planning make this one of the most difficult sectors to decarbonize. In this episode of Unfold, we’ll look at how we can transition to low-carbon transportation.

A quarter of the world’s greenhouse gas emissions comes from heating and electricity. In this episode of Unfold, we talk with Alissa Kendall, professor in the Department of Civil and Environmental Engineering about our energy use. We’ll discuss renewable energy and other decarbonizing technologies and the importance of life-cycle analysis when discussing climate change solutions.

Oceans have always done us a favor, absorbing carbon dioxide in the atmosphere. But now rising greenhouse gases are warming the ocean and changing its chemistry. All of this is putting marine species and ecosystems at risk, threatening food security and the livelihoods of people along its shores. In this episode of Unfold, we’ll take a deep dive into the ocean to examine the effects of climate change.

Agriculture is responsible for 24 percent of our global greenhouse gas emissions. Despite this, UC Davis researchers say agriculture holds huge potential to be one of the biggest solutions to climate change. Carbon farming may hold the key. In this episode of Unfold, we examine how scientists are adding rock dust to crops to see if it can sequester carbon while also increasing yields for farmers.

It’s so easy. One click of your mouse and you’ve ordered just what you want, delivered to your doorstep in just a few days or even a few hours. Since COVID-19, our online shopping habits, particularly all those groceries, have increased dramatically. What that has meant for our carbon footprint might just surprise you. Miguel Jaller with the UC Davis Institute of Transportation Studies will unfold all the complexities of e-commerce in this brief bonus episode of Unfold.

California wildfires burned millions of acres this year, destroying entire towns and killing people. As wildfires become more difficult to control and more deadly, scientists say it will only get worse. Now, wind-driven wildfires like the Santa Anas that Southern California experiences, are moving further north and striking when conditions are hotter and drier. This episode of Unfold examines how fire is changing California’s landscapes and how we might manage this going forward.

By 2100, Sacramento is expected to feel much like Phoenix, which last year had more than 100 days over 100 F. In this Unfold episode, co-host Kat Kerlin discusses her “Becoming Arizona” series, which looks at how to prepare for a hotter future. We also examine how cities nationwide are dealing with triple threats: rising temperatures, racial inequities and a pandemic. And we’ll discuss the efforts needed to build socially just, climate-resilient communities.
