When we talk about how climate change impacts our lives, many people are surprised to learn that it’s even affecting the way we should consider investing our money. And there’s a lot to consider, from supply chain issues to how committed companies are to climate action. In this episode, we asked an investment expert – Mark Hays – what do we need to know to build climate-smart portfolios?

Mark Hays is the president of Endowments & Foundations at Prime Capital.** At Prime, Mark is responsible for overseeing Prime’s national nonprofit practice, seeking to deliver comprehensive institutional investment management, mission, and impact strategy, and foundation governance and philanthropic strategy.

Mark brings nearly two decades of institutional investment experience with a focus on sustainable investing, including in roles at Glenmede, J.P. Morgan Asset Management, and Cambridge Associates. Mark earned his M.B.A. from London Business School, his B.S. from Wake Forest University, and completed executive education in sustainability leadership from Harvard University. He is on the leadership committee of CFA Society Philadelphia and is on the board of Believe in Students, a national education-focused nonprofit.

**At the time of recording, Mark was managing director and director of Sustainable Investing at Glenmede.

Sports are a major part of our lives. Many of us play some sort of sport, whether professionally or recreationally. Still more are avid fans – hours and hours spent rooting for our favorite teams and sitting on the sidelines cheering on our children. But as climate change affects our weather, athletes and spectators are feeling the heat. In this episode, we asked a sports expert – Walker Ross – is it getting so hot we’ll have to call off the game?

Walker J. Ross is a lecturer in sport management and digital marketing at the University of Edinburgh and the director of the Sport Ecology Group, a nonprofit collective of academic educators and researchers. His research focuses on the bidirectional relationship between sport and the natural environment.

Insuring our homes used to be a given. Today, it’s increasingly a luxury that more and more can’t afford – if it’s even available at all. Climate change is wreaking havoc on the insurance industry as rising sea levels, severe weather, and other impacts threaten our biggest assets – our homes. In this episode, we asked an insurance expert, Ben Keys, will we be able to protect our homes in the near future?

Ben Keys is the Rowan Family Foundation professor of real estate and finance at the University of Pennsylvania’s Wharton School and a research associate of the National Bureau of Economic Research. Keys's recent research has focused on climate risk, housing, and mortgage markets; foreign investment in the U.S. housing market; and the geography of household financial distress. His research has been published in such journals as the Quarterly Journal of Economics, American Economic Review, Econometrica, Journal of Financial Economics, and Review of Financial Studies, and has been profiled in The Economist, The Wall Street Journal, and The New York Times.

Before joining Wharton, Keys taught at the University of Chicago and worked as a staff economist at the Board of Governors of the Federal Reserve System. He holds a B.A. in economics and political science from Swarthmore College and an M.A. and Ph.D. in economics from the University of Michigan.

We’re all wondering the same thing – what IS causing all of this weird weather … and is it going to get much worse? Kathleen talks with meteorologist Bernadette Woods Placky to get some context, taking a deep dive into how climate change is supercharging our weather -- from extreme heat waves and monster wildfires to excessive rainfall and dire droughts -- and its far-reaching effects on the things we rely on every day -- like healthy agriculture systems, fresh water, and disease control.

Bernadette Woods Placky is the executive director and co-founder of Talking Climate Collaborative. A meteorologist, climate science communicator, and network builder with more than 25 years of experience translating complex science into stories that move people and institutions to act, Bernadette is a leading expert on the connections between weather and climate change.

Prior to her current role, Bernadette was vice president of engagement and chief meteorologist at Climate Central, where she built and led Climate Matters, an innovative climate journalism and communication program. Through convenings, data analysis, content creation, and sustained engagement, she grew and supported a network of more than 3,000 media professionals across the United States and internationally.

Before Climate Central, Bernadette spent more than a decade as a TV meteorologist, earning an Emmy for Best Weathercaster. She is a fellow of the American Meteorological Society, earned the Certified Broadcast Meteorologist seal, and was elected to its council. She serves on the National Academies Board on Atmospheric Science and Climate, as an advisor for C-Change Conversations, on The Watershed Institute’s advisory board, and on the Princeton Wrestling Club Board.

Bernadette graduated from Penn State University with a BS in meteorology and a minor in French.

C-Change Conversations’ Kathleen Biggins sits down with New York Times award-winning Reporter David Gelles for an in-depth discussion about climate, capitalism, and culture, areas of expertise that he delves into in his forthcoming book, “Dirtbag Billionaire: How Yvon Chouinard Built Patagonia, Made a Fortune, and Gave It All Away.”

Kathleen joins Mark Hayes of Glenmede for a wide-ranging conversation about how climate change is transforming the finance sector. They explore the risks and opportunities of the global climate transition, the rise of sustainable investment strategies, and the regulatory and political shifts shaping today’s landscape. The discussion also dives into how corporate leadership in the C-suite is responding to climate challenges, the growing trend of “greenhushing,” and the federal policy changes influencing the pace of climate action.
