Dr. Katharine Hayhoe – How to Understand and Talk About Climate Change

The Intergovernmental Panel on Climate Change recently produced a report showing that the world needs to cut carbon pollution far more quickly than current rates to avoid severe consequences. But how can the global community achieve its climate goals when the conversation around climate change is often hyper-polarized?

To discuss this question and other issues, on the latest episode of the Columbia Energy Exchange host Jason Bordoff sat down with Dr. Katharine Hayhoe, an atmospheric scientist, professor of political science, and director of the Climate Science Center at Texas Tech University. Dr. Hayhoe has been a recipient of numerous awards, including TIME’s 100 Most Influential People and Foreign Policy’s 100 Leading Global Thinkers.

Over the course of the conversation Jason and Dr. Hayhoe discussed how she merges her faith as an evangelical Christian and her scientific professional work, what needs to be done to win hearts and minds on the issue of climate change, and the role that renewables and policy can play in addressing this global challenge.

Trends and 2025 Insights on the Rise of Electric Vehicles in the USA

Plug-in electric vehicles (EVs) are reshaping the transportation energy landscape, providing a practical alternative to petroleum fuels for a growing number of applications. EV sales grew 55× in the past decade (2014–2024) and 6× since 2020, driven by technological progress enabled by policies to reduce transportation emissions as well as industrial plans motivated by strategic value of EVs for global competitiveness, jobs and geopolitics. In 2024, 22% of passenger cars sold globally were EVs and opportunities for EVs beyond on-road applications are growing, including solutions to electrify off-road vehicles, maritime and aviation. This Review updates and expands our 2020 assessment of the scientific literature and describes the current status and future projections of EV markets, charging infrastructures, vehicle–grid integration and supply chains in the USA. EV is the lowest-emission motorized on-road transportation option, with life-cycle emissions decreasing as electricity emissions continue to decrease. Charging infrastructure grew in line with EV adoption but providing ubiquitous reliable and convenient charging remains a challenge. EVs are reducing electricity costs in several US markets and coordinated EV charging can improve grid resilience and reduce electricity costs for all consumers. The current trajectory of technology improvement and industrial investments points to continued acceleration of EVs. Electric vehicles are increasingly adopted in the USA, with concurrent expansion of charging infrastructure and electricity demand. This Review details these trends and discusses their drivers and broader implications.
