For climate activists, New York's lights shine too bright

NEW YORK — New York’s annual Climate Week is underway, bringing together activists, politicians and business leaders for hundreds of events aimed at addressing the planetary crisis. 

“People are looking for ways that we can make a meaningful difference in short order, given the magnitude of the crisis that is facing us. And one of the simplest things we can do is to look around and figure out where we can cut waste from the system,” he argued. 

Globally, the IDA estimates that outdoor lighting that escapes to space is responsible for 1 per cent of annual greenhouse emissions. 

BIRDS, STARGAZING AND HUMAN HEALTH AFFECTED

It’s not just an energy problem, either.

New York City lies along a bird migration pathway known as the Atlantic Flyway, with millions passing through every year, Mr Dustin Partridge, director of conservation and science at the New York City Audubon, told AFP.

Artificial light draws the birds into the city. During the day, they crash into buildings because they see reflections of enticing vegetation in the glass and concrete jungle, while at night they fly into lighted windows. 

“In New York, we have about a quarter million birds die each year with collisions,” said Mr Partridge, with Climate Week occurring in the middle of the fall migration. 

The seeds these birds disperse are vital for the health of carbon-sequestering ecosystems all the way from Canada, where they began their journeys, to their destinations in South America.

“You can go outside in the evening in New York City and look out and see an easy solution to protecting biodiversity and helping fight against climate change,” said Mr Partridge. 

That’s to say nothing of the impact of light pollution on stargazing — the reason the IDA was founded in the first place.

“The light that’s been travelling millions of light years is being absorbed and hidden in the last nanosecond, and what a loss to society that is,” said Mr Hartley.

Other research has uncovered potential impacts on human health — for example, increased incidents of certain cancers, which could be linked to disruptions of circadian rhythms. Artificial light also brings more mosquitoes, and the diseases they bring. 

New York passed legislation in 2021 that required all city-owned buildings to turn off non-essential lights from 11pm (11am Singapore time) to 6am during spring and fall migration.

But these account for a small fraction of all buildings, and a bill introduced this May that would extend similar rules to privately-owned and industrial buildings, remains pending.

Critics argue New York’s nighttime skyline is an essential part of the city’s identity — a place of energy where people come to dream and achieve great things.

To this, the campaigners point to the examples of European cities that have begun flipping the switch when most are asleep — including in Paris, the “City of Lights”. AFP
