We’re barking up the wrong trees.
A new study reveals that a majority of the 7 million trees in New York City are emitting “volatile compounds” that do more harm than good for our air quality — especially during scorching heat.
“We’re all for planting more trees. They bring so many good things,” said study coauthor Róisín Commane, an atmospheric chemist at Columbia University’s Lamont-Doherty Earth Observatory. “But if we’re not careful, we could make air quality worse.”
The arbors in question include oaks and sweetgums which produce high volumes of a chemical composition called isoprenes — and they’re rooted in the Big Apple more than any other species.
“There is no reason to think that trees don’t play a role in what’s in the air,” said lead author Dandan Wei, of the local Columbia Climate School. “We just didn’t have the tools before this to understand this particular aspect.”
When that compound interacts with nitrogen oxide pollution, which is emitted from cars and building exhaust, the result is a key driver for respiratory illnesses.
Asthma and chronic bronchitis were listed as the most vulnerable conditions, according to the new report in Environmental Science & Technology.
And, if NYC continues its usual planting of those style trees, isoprene levels in Manhattan will surge about 140% with a 30% boost in ozone.
In the more lush borough of Queens, both isoprene and ozone are expected to quadruple, researchers note.
Oak trees, which already let out 800 times more isoprene than maples, emit in especially high volume when the city reaches boiling temperatures in the high 90s as well. They make up 37% of city trees while the sweetgums consist of 17%.
After analyzing satellite imagery that combined with Parks Department data, the research team found that local trees played a role...

Chop ‘em down then.

Time to summer evacuate to the Catskills.
So now the tree huggers will chop them all down?

“Volatile compounds” 🙄
Like flammable O2. That we breathe. To live.

Ignorance is strength.
Trees cause air pollution.
I’m calling BS on the good professor.

But urban green spaces also play an underappreciated role in absorbing atmospheric CO2 and in combating global warming, according to a new Columbia study of vegetation in New York City. On a typical summer afternoon, the researchers discovered, the trees, shrubs, flowers, herbs, and grasses in New York’s five boroughs collectively absorb more than 40 percent of the city’s total CO2 emissions.
“That’s a much larger impact than we expected to see,” says atmospheric chemist Róisín Commane, who led the research team at the Columbia Climate School’s Lamont-Doherty Earth Observatory.
“We already knew that street trees had this great benefit of cooling and providing shade,” she says. “That they’re also inhaling enormous amounts of CO2 is an added bonus.”
“Like flammable O2.”
Oxygen is not flammable.

You are off-point. Did you read the article?
Remember when these same a-holes were crying “Save a Tree”...”Hug a tree!!”
One of the few undeniably true things about global warming is that concrete jungles (i.e., big cities—where Democrats predominate) are heat sinks that are a good bit hotter than surrounding rural areas. Trees would help mitigate that.
But, nooooooo....Plant more concrete.
“Volatile compounds” 🙄
Like flammable O2.
O2 is not a compound.
