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...

So then you think we should NOT plant more trees.
DING.. DING.. DING.. We have a WINNER!

Thank you.
Romeo y Julieta please.
ROFL!! Leave it to beaver.
“I’m calling BS on the good professor.”
Why are you against planting trees?

Why are you also against planting trees?
I owe you thanks for the correction. Thank you!
I’m full of errors today. Thanks again for setting me straight.

Article 2. Every hour, the Congress shall adjust that thermostat.
Article 3. The Congress shall set the maximum level of the oceans.
Article 4. The Congress shall set the miles per Kilowatt.
Article 5. The Congress shall set the rotational speed of the planet earth.

Are they admitting Reagan was right?
Don’t forget the gaseous discharges from illegals…….

They've known for years which trees release what.
The Great Smoky Mountains is proof of that.
Planting oaks near homes is a BAD idea anyways.
My son has a big, old one at the end of his driveway and it’s one of the messiest trees I’ve ever seen. I would have chopped it down for firewood years ago if I were him.

Sweetgums 17 per cent? I’d think there would be more Ailanthus (tree of heaven). Ailanthus grows everywhere in NYC. It’s a giant weed almost. Empty lots, garbage piles, rooftops, fence lines, highway medians, railroad rights of way, or anywhere there is enough dirt. I had one growing from the top of my chimney and I had to climb up to pull it out. Another sprouted in my basement window well.
