Dear EarthTalk: Cities seem to be heating up fast more so than less urban areas. What can we do to keep them cool in the face of increasing global warming? — Paul Smith, Providence, R.I.
As global warming intensifies, cities worldwide are experiencing an accelerated rise in temperatures compared to less urban areas. This phenomenon, known as the urban heat island (UHI) effect, results from the concentration of buildings, roads and other infrastructure that absorb and re-emit heat more than natural landscapes. Addressing urban heat is crucial in the context of global warming to improve public health, reduce energy consumption and enhance the livability of urban environments.
One effective strategy is the implementation of green infrastructure. Urban green spaces, like parks and tree-lined streets, provide shade and cool the air through evapotranspiration, whereby heat is reduced as water evaporates from soil surfaces and transpires from plant leaves. Urban green spaces can significantly reduce the surrounding air temperature, offering a natural solution to urban heat.
White roofs can reflect up to 90 percent of sunlight, reducing heat absorbed by buildings.
Reflective and cool roofs are another strategy to mitigate urban heat. White roofs can reflect up to 90 percent of sunlight, significantly reducing the amount of heat absorbed by buildings. Several cities have successfully implemented white roofs, demonstrating their effectiveness in lowering urban temperatures. Cool roofs, made from lighter colored materials, offer another viable solution. These can be constructed from various materials, including reflective coatings, tiles and membranes. Implementing cool roofs helps reduce urban heat and contributes to energy savings by lowering the need for air conditioning.
Urban design and planning also play a key role in managing urban heat. Cool pavements, which include reflective and permeable materials, can greatly reduce heat absorption versus asphalt and concrete. Cities like Los Angeles have started using cool pavements, showing promising results. Other technological innovations offer advanced solutions for urban cooling. Smart shading systems, which adjust automatically based on the sun’s position, and other innovative technologies, can enhance the effectiveness of traditional methods. Urban climate modeling is another valuable tool that helps urban planners make informed decisions in implementing different heat mitigation strategies.
Globally, many cities have successfully implemented measures to combat urban heat. Singapore’s green roof initiative and Melbourne’s urban forest strategy have had significant impacts on local temperatures. Urban planners, policymakers and communities must adopt multi-faceted approaches and policies to create cooler, more resilient urban environments and protect the health and well-being of city dwellers.

Telecom Reg’s Best Kept On the Books
When Connecticut land-use commissions update their regulations, it seems like a no-brainer to jettison old telecommunications regulations adopted decades ago during a short-lived period when municipalities had authority to regulate second generation (2G) transmissions prior to the Connecticut Siting Council (CSC) being ordered by a state court in 2000 to regulate all cell tower infrastructure as “functionally equivalent” services.
It is far better to update those regs instead, especially for macro-towers given new technologies like small cells. Even though only ‘advisory’ to the CSC, the preferences of towns by law must be taken into consideration in CSC decision making. Detailed telecom regs – not just a general wish list -- are evidence that a town has put considerable thought into where they prefer such infrastructure be sited without prohibiting service that many – though not all – citizens want and that first responders rely on for public safety.
Such regs come in handy when egregious tower sites are proposed in sensitive areas, typically on private land. The regs are a town’s first line of defense, especially when cross referenced to plans of conservation and development, P&Z regulations, and wetlands setbacks. They identify how/where the town plans to intersect with the CSC process. They are also a roadmap for service providers regarding preferred sites and sometimes less neighborhood contention. In fact, to have no telecom regs can weaken a town’s rights to protect environmental, scenic, and historic assets, and serve up whole neighborhoods to unnecessary overlapping coverage and corporate overreach. Such regs are unique to every town and should not follow anyone else’s boiler plate, especially industry’s.
Connecticut is the only state that has a centralized siting entity for cell towers. The good news is that applicants must prove need for new tower sites in an evidentiary proceeding and any decisions have the weight of the state behind them. The bad news is that the CSC used to be far less industry-friendly and rote in their reviews, which now resemble a check list. There is an operative assumption at CSC that if an applicant wants a tower, they must need it, otherwise why spend significant money to run the approval gauntlet? This reflects a subtle shift over the years at CSC from sincere willingness to protect the environment toward minimal tweaking of bad applications with minor changes. The bottom line is that towns really cannot rely on the CSC to do all the work for them.
What CSC issues telecom providers is a “certificate of environmental compatibility” after an evidentiary proceeding (not unlike a court case) with intervenors, parties, expert witnesses, and the service provider’s technical pro’s sworn in and subject to cross examination. Service providers get to do the same with any opposition from intervenor/party participants – like towns and citizens -- and their experts. It’s an impressive process whose ultimate goal is the fine balancing between allowing adequate/reliable public services and protecting state ecology with minimal damage to scenic, historic, and recreational values. They unfortunately often fall short of their mandate – like approving cell towers with diesel generators over town aquifers -- evidenced by CSC only rejecting about five cell towers in the past 15-20 years.
The CSC was founded in 1972 and clarified its mission in the 1980’s to prevent the state from being carved up willy-nilly by gas pipelines, high tension corridors, and broadcast towers. With the sudden proliferation of cell towers beginning in late 1990’s, it became the most sued agency in Connecticut by both an arrogant upstart industry if applications were denied and by towns/citizens when bad sites were forced on them. CSC gradually formed a defensive posture that drives their decisions toward industry with deeper pockets and attorneys on retainer.
For citizens, nothing can wreck one’s day like the CSC. It behooves towns to protect what little toolkit they have, and understand the legal parameters of the CSC’s playing field. The CSC is not a “normal” government agency where municipal/citizen redress is based on logic and local support. Their process is largely immune to everything but specific kinds of evidence – like town regs with setbacks/fall zones, radio frequency transmission signal strengths, sensitive areas identified, and detailed wildlife inventory, among others.
There is a current cell tower fight involving two intervening towns -- Washington and Warren; both with good cell tower regs – over a tower site within 1200’ of a Montessori School, near Steep Rock’s nature preserves with comprehensive geology/wildlife databases that include endangered, threatened and special concern flora and fauna, on established federal/state migratory bird flyways, within throwing distance to a historic site capable of being listed on the Underground Railroad, and with an access road on a blind curve entering a state highway that will permanently damage wetlands, vernal pools, and core forests. There are well credentialed environmental experts, including Dr. Michael Klemens, former chair of Salisbury’s P&Z, as well as the former director of migratory bird management at the US Fish and Wildlife Service, and an RF engineer testifying to alternative approaches, plus three attorneys representing intervenors. It is the most professional challenge I have seen at CSC since Falls Village successfully mounted one that protected Robbins Swamps several years ago.
The hearing is ongoing, with uncertain results. To see what it takes today to stop an inappropriate tower siting, see Docket #543 under “Pending Matters” at https://portal.ct.gov/csc before removing local cell tower regs – the lowest hanging fruit that any town can possess in case it’s needed.
