Cooling Murals to Reduce Surface Temperature
July 13th, 2026
Now this is a cool project! Students and volunteers from the Yale and New Haven communities recently painted a “cooling mural” on the basketball court at Kimberly Field in the city’s Hill neighborhood. Using a highly reflective paint, the mural reduces surface temperatures and offers some relief on steamy summer days. Enjoy the aerial footage! Led […]

Via Grist, a look at how the solution to urban heat could be much, much simpler than many people think: Johnny Appleseed was ahead of his time. Not because he fed so many people by planting apple trees (really, he got them drunk instead, as his real goal was encouraging the production of cider), but because […]

Via The Conversation, a report on the potential for trees and greenery to cool cities: Cities around the world are planting more trees to cope with rising urban heat. But our research shows trees alone are often not enough. In some cases, the wrong kind of greening can even make streets feel less comfortable on a hot […]

November 9th, 2025
Via the Center for Strategic and International Studies, a report on extreme heat: The Issue Extreme heat is becoming an urgent priority in the United States and beyond. The threat posed by extreme heat has become a matter of national security, impacting U.S. military readiness, while threatening economic growth, productivity, and global competitiveness. The negative […]
Read more »'Black Swans' are highly improbable events that come as a surprise, have major disruptive effects, and that are often rationalized after the fact as if they had been predictable to begin with. In our rapidly warming world, such events are occurring ever more frequently and include wildfires, floods, extreme heat, and drought.
'Green Shoots' is a term used to describe signs of economic recovery or positive data during a downturn. It references a period of growth and recovery, when plants start to show signs of health and life, and, therefore, has been employed as a metaphor for a recovering economy.
It is my hope that Black Swans / Green Shoots will help readers understand both climate-activated risk and opportunity so that you may invest in, advise, or lead organizations in the context of increasing pressures of global urbanization, resource scarcity, and perils relating to climate change. I believe that the tools of business and finance can help individuals, businesses, and global society make informed choices about who and what to protect, and I hope that this blog provides some insight into the policy and private sector tools used to assess investments in resilient reinforcement, response, or recovery.
