Shade: The Promise Of A Forgotten Natural Resource.
August 10th, 2025
Via The Atlantic, a look at how — to survive a heating planet —humans need shade, lots of it: Every year, heat takes more lives than floods, hurricanes, and tornadoes combined. The fatalities can sometimes go unnoticed, perhaps because the danger is invisible: There’s no twister that uproots a neighborhood and no flood that sucks it […]

Via Bloomberg, a look at the growing use of air conditioning in Europe: Many homes in Germany don’t have air conditioning and are now using portable units to cool down due to increasingly frequent heat waves.

July 20th, 2025
Via WRI, a look at how better infrastructure can help cool cities: In a city, a grassy park might be a place to stretch out with a book, an asphalt road your route to work, a building wall a canvas for a mural. But beyond their familiar roles, each of these surfaces plays a critical […]

July 7th, 2025
Via Grist, a look at how – with white or reflective roofs significantly reducing temperatures – Atlanta is the latest city to mandate their adoption: Walk outside into 100-degree heat wearing a black shirt, and you’ll feel a whole lot hotter than if you were wearing white. Now think about your roof: If it’s also […]

June 25th, 2025
Via Anthropocene Magazine, a look at an innovative paint that replenishes its water supply by absorbing rain and water vapor. Its porous structure holds the water and then slowly releases it much like sweat. Ultra-bright white paints are the go-to when it comes to cooling buildings. Those paints work by reflecting as much of the sun as […]
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.
