UArizona experts available for Earth Day

TUCSON, Ariz. – Earth Day, celebrated April 22, marks the anniversary of the birth of the modern environmental movement in 1970. The theme this year, according to global organizers, is "Invest in Our Planet."

But what exactly does that mean?

"To me, it means making decisions today with an eye toward the environmental impacts of tomorrow," said Derek Lemoine, an associate professor in the Department of Economics in the University of Arizona Eller College of Management.

Lemoine's research focuses on measuring the cost of climate change and developing policy frameworks to more efficiently mitigate climate change. He says one possible strategy would be to make all prices reflect the cost of using the planet's resources, rather than allowing the use of those resources nearly for free. For example, it currently doesn't cost anything to pump carbon dioxide – which contributes to climbing global temperatures and a changing climate – into the atmosphere.

"Economics is at the heart of the climate change problem, both for determining how climate change affects people and for how we can best control climate change," Lemoine said. "We have markets that work for us to help us make decisions throughout the day. We ask ourselves if our perceived value for a certain product or service is worth its price. Your whole carbon footprint is basically unpriced. If it's eventually priced, the market can decide if it's right."

The following UArizona experts are available to speak about various topics for Earth Day:

Derek Lemoine, associate professor in the Department of Economics, explores, among other topics, how environmental and economic uncertainties and the interaction between energy systems and innovation should affect the design of climate change policy. His recent research shows how to learn about the cost of climate change from weather impacts, how to use financial markets to value forecasts of El Niño events and winter weather, and how to incentivize carbon removal technologies.

Paul Blowers is a distinguished professor in the Department of Chemical and Environmental Engineering. He studies how choices – regardless of whether they are made at a company, factory or household – impact the environment. He uses quantum chemistry techniques to identify compounds that may be greenhouse gases before they are even manufactured. He combines this information with his engineering skills to do calculations to explore whether banning potential greenhouse gases in different uses – such as refrigerants, solvents or other areas – would lead to unintended consequences.

Holly Thomas-Hilburn, director of Arizona Project WET,  teaches adults – including K-12 teachers, UArizona students who work with the project as "water educators," and hundreds of volunteers – how to better engage K-12 students in science and help them feel a connection to the natural world. She believes that students who have a greater understanding of natural systems will be prepared to be the decisions makers of the future. Arizona Project WET's Recharge the Rain initiative engages teachers and students in rainwater harvesting.
