good morning. This is what you need to know to start your day.
Give it for the trees in the city of Los Angeles
New research has found that we are incredibly good at absorbing the carbon dioxide, energy consumption and corporate industrialization that we expel into the air.
Last month, he was a researcher at Dornsife College, Letter, the Journal of Environmental Science and Technology, Arts and Sciences.
Using an array of sensors set up in the central LA band, the team tracked CO2 emissions over 18 months. Research shows that over the course of the year, trees averaged up to 60% of their CO2 emissions during the day.
“It’s a huge number,” said Will Bellelson, a USC professor of Earth Sciences who led the research. His initial response to the data was not as scientific as it was to be included in the journal, but I think it will work for this newsletter.
“Wow… La Tree is kicking the butt.”
All are on CO2 Express
Bellerson’s team approached measurements similar to how transport measures ridership. That was possible, he explained for the main winds of LA moving from west to east.
Using 12 sensors, researchers tracked the CO2 Express over a 30-square-mile section of the city, from Lovelair Avenue, located between 3rd Avenue and Obama/Exhibition Boulevard, to the Boyle Heights and Lincoln Heights neighborhoods.
“We actually see the air moving through the city,” Bellelson told me. “There’s a change happening right in front of you with these sensors. You can see the change as the air passes, on the west, towards the middle of the city, and further east.”
Data showed a CO2 reduction, indicating that trees in this region capture an average of up to 60% emissions during the day (only trees and vegetation absorb CO2 and require sunlight during photosynthesis). This averages around 30% in a full 24-hour day, Bellerson noted.
What behaviors can research help?
Berelson hopes the model can be used in other cities where it is trying to track and reduce CO2 emissions.
He was also surprised at how much CO2 trees in the area were captured, thinking, “This is part of LA and it’s not actually attacking you as being that green.”
That lack of trees is a continuous challenge in the city, where communities experience the benefits of being offered through the trees and cleaning the air.
Bellerson said expanding the study could help LA and other cities “become quantitative (and) scientific about how planting methods are planned.
And while urban trees show “the creepy ability to quickly intake lots of CO2,” he stressed that planting more trees alone is not a singular solution to the region and the climate crisis.
“Emission reductions must happen,” Bellerson said.
More tree research is underway
Greenhouse research is underway at USC to see which species of trees capture the most carbon.
“We actually have to look closely at the types of trees we plant because it can make a huge difference.
The study analyzes how trees are affected by warming climates.
And this initial study area included major highway intersections (including 10, 110, and 5), but we didn’t get a good look at the emissions near roads that emit high volumes. He told me that Bellerson’s team will work to analyze data that moves forward.
Researchers also recently installed more sensors at both ends of the first survey area, and “there are long trains to watch,” Belson said.
These follow-up studies are probably over a year away, so stay tuned!

These California coastal cities face increasing flood risk from the tsunami, data shows
- Marina del Rey, Long Beach and nearby Swas at Dual Port Complexes could be flooded at an altitude of 15 feet above sea level.
- The worst tsunami could flood a significant area of Oakland, Berkeley and Alameda up to 18 feet above sea level.
- However, for most Californians, the exact extent of tsunami risk is less important than knowing that hazard zones exist in the first place.

- Medi-cal costs are billions more than estimates since last summer, when California has experienced higher than expected costs, increased enrollment and increased program pharmacy costs for expanding undocumented immigrant compensation.

A must-see for this morning
. Before the January fire broke out, Brian Gardner had 300 Polaroids on the walls of a saloon in his basement. He had over 1,000 bottles of liquor. But the Polaroid, where he hangs around the 300-square-foot bar, surrounded by a storage room under the stairs of Altadena’s house, was even more important to him.
