A new scientific study has shown the positive correlations between public health and tree planting in urban areas. In a report published recently by The Lancet medical science journal, a team of European researchers shared data on mortality rates in 93 cities in the summer of 2015 that... View full entry
Kargbo grew up to become a banker, but she has spent the last several years working in the administration of Freetown mayor Yvonne Aki-Sawyerr, a noted climate activist. Before becoming the city’s chief heat officer, she headed up the city’s sanitation department [...] Kargbo says her work is to keep climate change on the agenda, however many other things are tugging the world’s attention away. — Experience Magazine
A former aide to the noted climate activist Mayor of Freetown Yvonne Aki-Sawyerr, Eugenia Kargbo is one of five official Chief Heat Officers (CHOs) in the world. After being appointed in 2021, she joins fellow CHOs from Athens, Miami, Santiago, Chile, and Monterrey, Mexico in a program... View full entry
In time for the start of summer, the global fraternity of Chief Heat Officers has grown as cities decide to commit themselves to full-time professionals from the subfield of public design in the face of mounting challenges caused by climate change. The city of Monterrey, in the Mexican state of... View full entry
Research undertaken by NASA has found that rooftop gardens can offer substantial temperature reductions in cities during summer months. In a study published in the journal Sustainable Cities and Society, the group used satellite imagery to measure temperatures at three rooftop gardens in Chicago... View full entry
As the United States suffers through a summer of record-breaking heat, new research shows that temperatures on a scorching summer day can vary as much as 20 degrees across different parts of the same city, with poor or minority neighborhoods often bearing the brunt of that heat. — The New York Times
Using a series of dramatic, color-coded maps, The New York Times highlights the growing disparity between exactly which neighborhoods in America feel the ever-increasing urban heat island effect. The report details stark temperature differences between the neighborhoods of several major... View full entry
On top of climate change, cities grow hotter and hotter due to an increase in urban heat island effect. According to Philip Oldfield's Guardian piece, "What would a heat-proof city look like?," there are four solutions cities can implement to decrease rising temperatures. Oldfield explains green...

Plans for the much-touted Pershing Square Renew project in Los Angeles appear to be shifting. Curbed reports that three years after being selected as the winning entry for an international competition to redesign the five-acre postmodern urban park, a team led by French landscape architects...

Under a plan announced last week by Mayor Anne Hidalgo, thickets of trees will soon appear in what today are pockets of concrete next to landmark locations, including the Hôtel de Ville, Paris’s city hall; the Opera Garnier, Paris’s main opera house; the Gare de Lyon; and along the Seine quayside. — citylab.com
"Islands of freshness" are on the way to Paris, according to a recently-unveiled plan by mayor Anne Hidalgo. The environmentally-aggressive mayor is aiming to have 50 percent of the city's land area taken up by permeable surfaces and planted areas, Citylab reports, and so, she is turning spaces...

UNStudio is known for their groundbreaking work in solution driven designs relating to the ever-changing urban environment. Climate is changing, which leaves architects and designers taking steps towards designing buildings and structures that can accommodate to the overheated urban environment... View full entry
A new study by researchers at the University of Southern California found that replacing all lawns with drought-tolerant vegetation would have a net cooling effect of 0.2°C — but the science is less obvious than you might think. In fact, converting lawns has resulted in daytime warming of up... View full entry
It is well established that white roofs can mitigate the urban heat island effect, reflecting the sun's energy back into space and reducing a city's temperature. In a new study of Guangzhou, China, researchers found that during a heat wave, the effect is significantly more pronounced. Reflective roofs, also called cool roofs, save energy by keeping buildings cooler, thus reducing the need for air conditioning. — Science Daily
According to a new study by Berkeley lab researchers Dev Millstein, Ronnen Levinson, and Pablo Rosado, alongside Meichun Cao and Zhaohui Lin of the Institute of Atmospheric Physic in Beijing, so-called "cool roofs," or roofs painted white, substantially reduce the urban heat island effect during...

the greater L.A. area sees more additional heat than any other region, in part because of how urbanized it is. [...]
Solutions include planting more trees and bushes, painting roofs white so they don’t absorb as much heat and using lighter colored concrete on streets and sidewalks.
