Of course, since this is a cult, they’re still going to link anthropogenic climate change to UHI
Raleigh, Durham warming: Data shows cities have several urban heat islands
Many people might not associate a warming climate with cities and urban areas, but a new project shows how much the increasing global temperature it is actually affecting the Triangle.
Yeah, pretty much every Skeptic will associate urban and dense suburban areas (Raleigh and Durham are very much huge mixed use, like so many cities in the South) with artificially increasing localized temperatures.
In July of last year, volunteers in Raleigh and Durham used heat sensors mounted on cars and bicycles or carried in their pockets to collect data about how warm areas were.
More than six months and nearly 100,000 data points later, the results are in.
“It’s important to understand that extreme heat is not distributed evenly or equitably across environments,” said Myleigh Neill, with the State Climate Office of North Carolina.
Neill was one of several presenters Thursday night, sharing the findings. One of the most interesting points: parts of our cities are warmer than researchers thought.
Originally it was believed that the difference in the hottest and coolest parts of the cities varied by 6 degrees. However, the data collection reveals that it is actually a wider margin – Raleigh differed 9.6 degrees; Durham, 10.4.
Well, yeah, that’s the way it works. I’m betting my part of the town, right on the edge near the river, away from most of the dense areas and big buildings, is cooler than the downtown area, near the malls, etc.
On the data collection day, volunteers went around the city three times – early in the morning, late afternoon and in the evening to gather readings.
Both Raleigh and Durham recorded hotter temperatures along major roadways – Capital Boulevard and N.C. Highway 147, respectively – during the early part of the day. Researchers noted that during this time, the Triangle appeared hazy and temperatured didn’t reach as high as forecasted due to smoke blowing in from wildfires out west. Still, as the day progressed and temperature climbed to 88.8 and 88.6 in each city, urban heat islands appeared.
Like I thought
“The term urban heat island refers to the fact that metropolitan areas tend to get much warmer than their outlying regions, especially during summer,” said Neill. “Temperatures on hot days can be amplified by paint and dark surfaces like roads, parking lots and buildings. These surfaces absorb and retain [heat] during the day, and then they radiate that heat back into the air. And this drives a significant increase in air temperature and heat index in certain areas within a city which can get much hotter than green areas.”
Yes, we know this. And, it means less cooling at night, because the heat is retained. That also goes with less radiative cooling due to low level smog and other particulates, which is an environmental issue. I wonder how this compared during much of 2020, when the air was cleaner from fewer vehicles on the road and businesses in operation?
Anyhow, they should really compare the data to outside the city, when you get to places like Wendell, Zebulon, Holly Springs, and others. What are their temperatures doing? It’s nice to see that they “discovered” something Skeptics have known about for decades.
