On August 7, when the thermometer reached a high of 93 degrees, a squad of 85 temperature detectives fanned out across Houston and Harris County. Their objective: Map the area's urban heat.

Organizers of the one-day endeavor pinpointed 320 square miles of Houston and Harrison County for collection of data about urban heat. Hardware attached to cars and bicycles traveling on predetermined routes took temperature and humidity readings during three one-hour periods: 6-7 am, 3-4 pm, and 7-8 pm.

The devices tracked temperature changes throughout the day in places featuring various characteristics, such as lots of green space, pavement or buildings. In all, the "street scientist" volunteers measured temperature and humidity in 32 heat-mapping pockets covering 10 square miles each.

The heat-mapping initiative was coordinated by the Houston Harris Heat Action Team, a collaboration of the Nature Conservancy of Texas, Houston Advanced Research Center, City of Houston, and Harris County Public Health. The team's corporate partners are Lowe's and Shell.

The team says urban areas are especially prone to high temperatures due to a combination of hard surfaces (buildings and roads), limited vegetation (such as trees), and heat generators like cars and factories.

"This problem, known as the urban heat island effect, can create issues for human health, infrastructure, and quality of life. Understanding how temperatures vary based on qualities of the natural and built landscape can inform how we reduce the impacts of rising summer temperatures in our communities," the team says.

Marissa Aho, the city of Houston's chief resilience officer, says the heat-mapping data will be available this fall through an open-source platform. Aho offers a heat-mapping project in Honolulu as an example of how Houston's data will be presented.

The Resilient Houston plan, released in February by Houston Mayor Sylvester Turner, called for a heat-mapping effort like the one carried out August 7 and outlined ways to reduce urban heat, such as planting 4.6 million new native trees over the next 10 years and retrofitting roofs to decrease heat absorption. Aho says the heat-mapping data will bolster initiatives to lessen the "urban heat island" effect.

"Houstonians do not prepare for heat like we prepare for hurricanes, but we should," Turner says in a release. "Houston is getting hotter, and we need science and data to help identify where the greatest impacts are so we can keep Houstonians safer and our city more resilient."

According to the U.S. Department of Homeland Security, extreme heat — defined as at least two consecutive days with temperatures above 90 degrees — ranks as the country's No. 1 cause of weather-related deaths. A 2017 study published by the National Resources Defense Council found the Houston area averaged 18 dangerously hot summer days per year from 1975 to 2010. Without any action to combat urban heat, Houston's annual number of days hit by dangerous summer heat could rise to 80 from 2046 through 2055 and 90 from 2091 to 2100.

Urban heat "leaves vulnerable communities susceptible to the dangers of stress and stroke, leads to higher ozone levels, and reduces the quality of life for all residents of the region — creating especially dangerous conditions for communities already striving to overcome historic obstacles around access and resources, as well as those who engage in outdoor work and recreation," according to the release from the Houston Harris Heat Action Team.

Aside from the human toll, urban heat exacts a financial toll. A 2017 study by researchers in the United Kingdom, Mexico, and the Netherlands indicates overheated cities face climate-change costs at least twice as high as the rest of the world due to urban heat islands.

Organizers of Houston's heat-mapping project note that last August was the second warmest on record in the city, with seven consecutive days when the temperature topped 100 degrees. As climate change takes hold and Houston continues to expand, "these heat-related challenges continue to be exacerbated," the release states.

Jaime González, Houston Healthy Cities Program director at the Nature Conservancy, says the heat-mapping data gathered August 7 will help determine where to plant trees, install "green" roofs, and promote other heat-mitigation tactics.

"We have a number of nature-first solutions in our toolkit that can help us cool our cities, but the first step in combating climate- and infrastructure-caused urban heat is to know exactly where to start," González says.

Houston was one of 13 U.S. communities chosen to participate in this summer's Heat Watch program, led by Portland, Oregon-based environmental services company CAPA Strategies LLC and backed by the National Oceanic and Atmospheric Administration (NOAA).

Early-stage startup accelerator names latest Houston cohort, new local leader

new to Hou

A national startup accelerator has announced its fifth local cohort, which includes five Houston companies participating in the spring 2022 class.

Madison, Wisconsin-based gener8tor has announced today the five participating startups in gBETA Houston. The program will be led by Muriel Foster, the newly named director of gBETA Houston, which originally launched in Houston in 2020 thanks to a grant from from the Downtown Redevelopment Authority.

The program, which is designed to help guide early-stage startups find early customer traction, connect with mentors, and more, is based in the Downtown Launchpad, and is free and does not take equity in the participating companies. The cohort kicked off on April 21 and concludes on June 10.

The new cohort includes:

  • Founded by CEO Steffie Thomson a year ago, Getaway Sticks has designed a shoe that gives women the painless support they need using athletic foam to create a shoe that gives women the painless support they need. Getaway Sticks provides the solutions to women’s #1 wardrobe complaint of high heel pain. Since launch, the company has earned over $35,000 in revenue from over 150 customers.

Vote now for your favorite 2022 Houston science teacher

Rewarding the Spark

Since 2019, alliantgroup and the Houston Independent School District have been partnering for the SPARK Award, a program that rewards outstanding HISD science teachers who are increasing student engagement and achievement through innovative lesson plans that emphasize both the importance and fun aspects of science.

The overall winner receives a $3,500 personal award plus $500 for their classroom, and the other five finalists receive $1,300 each plus another $500 to spend on their classrooms.

Get to know this year's crop of nominees below, then be sure to cast your vote once a day here until May 25.

After working for three years as an accountant, Lynell Dillard taught a weekly finance class where her students became her inspiration to pursue a full-time career in the classroom.

She secured her first teaching position in 2002 and hasn’t looked back. For three years now, she has been teaching science and giving her students hands-on learning opportunities they may not experience outside of the classroom.

Dillard explains that for many of her students, her role as a teacher is to give them as many opportunities to interact with the natural environment as possible. She knows many of her students and their families would not have access to these resources if it were not for the school district.

"We all learn in a different way, so we have to be willing to help that other person if they don’t get what I get, and there’s no criticism in it," Dillard says. "I tell them they are my future. Every single part of your education is important."


"Before I went to foster care, I was not doing well in my education," Ruth Giles says. "My foster mom, Nancy, took the time to figure out how I learned. She figured out I’m good with memorization, flashcards, and practicing. I would not be here without her today."

Sadly, Nancy passed away in January from COVID-19. Now, more than ever, it’s important to Giles that she continue sharing her experiences with her students to keep Nancy’s legacy alive.

Giles says the best part of teaching fifth-grade science is helping her students view the world in a different way, just like Nancy did for her.


Melanie Jenkins has been a fifth grade ESL teacher at Katherine Smith Elementary School for three years, but first got started in substitute teaching. She then went on to fulfill her childhood dream of working in finance, but found it wasn’t all she thought it would be.

"I still had in the back of my mind these kids whose lives I touched and who remembered me and understood what I was trying to teach them," she says.

Now she can't imagine doing anything else. It's challenging that many of her students are learning English for the first time, but she focuses on vocabulary and giving them resources in both English and Spanish is key, along with truly forming relationships with them.

“I try to figure out who likes what and how I can bring that into the classroom,” says Jenkins. “If you are a hands-on learner, we have the opportunities to put our hands on things. If you are a project-based learner, you have the opportunity to do projects. So there’s no one size fits all.”


According to science teacher Mimi Muñoz, STEM education is important but learning to be kind should be first in any classroom environment.

She also works hard to get her fifth-grade students engaged in their lessons and understand why science is important to their everyday lives.

“They get so excited to do hands-on activities, experiments, and projects,” Muñoz explains. “One thing I really want them to understand is that you need learning every day of your life. And learning science, as well as the world around us, is their real life. The things I’m teaching you [in the classroom] are important.”

Muñoz has been teaching for three years and spent her entire career at Seguin Elementary. She says the last two years were very tough on her students because of the pandemic, but despite virtual learning, it has only strengthened the way she connects to her students.


An educator of 17 years, Gerjuan O’Neal is following in her family’s footsteps.

"My maternal grandmother was a second and third grade teacher, and my maternal grandfather was a high school government teacher," she says. "My great-aunt was an elementary teacher and then a homebound teacher. My favorite thing is that I teach kindergarten through fifth grade, so every day is different."

She loves teaching STEM to her students because they can see how it applies to the other subjects they are also learning in school.

"I really like for my students to be creative problem solvers, and I like to show them all the different components of STEM," O’Neal explains. "If we are doing a science technology map, everything fits together. If we do a Lego build, we’re doing estimating with numbers. If we are coding, they get to see where math is involved and where they must be critical thinkers."


Although this is her first year teaching at Bonner Elementary School, Leticia Sifuentes is a veteran of the classroom with 24 years of experience.

Her favorite part about teaching is seeing her students become just as passionate about science as she is.

“I tell my students I’m a science nerd. We watch a movie — where’s the science? We go somewhere — where’s the science? They’re able to bring science to everything they talk about. It’s in reading, it’s in math, it’s just the way we can incorporate science in everyday life.”

Sifuentes was named an honorable mention teacher for alliantgroup’s 2019 SPARK Award, but three years later she says she is a better educator after working through the challenges of a pandemic and virtual learning. She now realizes that as an educator it is not only her responsibility to ensure her students are performing well academically but also emotionally, socially, and mentally.

Houston ranks as No. 3 city for Asian American entrepreneurs

diverse city

Known for its diversity, Houston ranks as the third best major metro area in the U.S. for Asian American entrepreneurs, according to a new study.

Personal finance website SmartAsset analyzed data for 52 of the largest metro areas to come up with the ranking. The analysis looked at nine metrics in three categories: prevalence of Asian-owned businesses, success of new businesses, and income and job security.

About 9 percent of the Houston metro area’s residents identify as Asian.

The SmartAsset study puts Houston in fifth place for the number of Asian-owned businesses (nearly 19,900) and in fourth place for the share of Asian-owned businesses (almost 17.9 percent) among all businesses. Furthermore, Houston ranks 14th for the increase (nearly 9.6 percent) in the number of Asian-owned businesses from 2017 to 2019.

Leading the SmartAsset list is the San Francisco metro area, followed by Dallas-Fort Worth. Austin comes in at No. 11 and San Antonio at No. 14.

The largest minority-owned business in the Houston area, as ranked by annual revenue, is Asian-owned private equity firm ZT Corporate.

Founded in 1997 by Chairman and CEO Taseer Bada, who was born in Pakistan, ZT Corporate is valued at more than $1 billion. ZT Corporate generates more than $600 million in annual revenue and employs over 3,000 people.

“As we look ahead, the vision for ZT Corporate is limitless. Our team will continue pushing boundaries and finding the bright spots in the economy that produce consistent financial gains for our investors,” Bada says in a news release marking his company’s 25th anniversary.

ZT Corporate’s flagship businesses are:

  • Altus Community Healthcare, a provider of health care services.
  • ZT Financial Services, a wealth management firm.
  • ZT Motors, which owns and operates auto dealerships. Last year, ZT Motors bought three Ron Carter dealerships in the Houston area.

“ZT Corporate is a vital asset to our citizens as a longtime local employer,” Houston Mayor Sylvester Turner says, “and has positively affected many lives through their health care organizations and philanthropic efforts.”
