Journalists at the Associated Press News reported on Dec. 3, 2025 that a study examining climate change’s potential impact on the economy was retracted due to overestimation of the effect on global income in 2025.

A 2024 study published in the journal Nature forecasted a 19% drop in global income by 2050 and a 99% chance that it would cost more to repair damages from climate change than it would to build efforts against it. Researchers at Germany’s Potsdam Institute for Climate Impact Research recently released a revised analysis which dropped the figures to a 17% reduction in global income and a 91% economic irreversibility rate.

While the original 2024 Nature study did contain data inaccuracies, according to AP News, “the heart of the study is unchanged,” with climate change continuing to hit the hardest in low-income areas.

Despite the minimal change in statistics, the sensitivity of the issue remains high.

AP Environmental Science teacher Dipti Patel said the unmentioned changes are signs of climate change’s increasing impact on local communities.

“Nowadays, the cost of insurance and food prices for almost everything has increased,” Patel said. “Looking at the local weather patterns, even in Houston, you realize that global warming really is happening now and we are all paying the price for it in different ways.”

Recent weather reports match these trends, with Houston breaking January heat records, experiencing temperatures more typical of late April.

For students living in Bellaire, like freshman Shayna Hassid, weather inconsistencies have been increasingly apparent.

“We’ve gone from 35 degrees one day to 75 the next,” Hassid said. “It gets pretty confusing.”

Bellaire’s HVAC systems have been experiencing difficulties since last year, and both students and teachers alike have felt the effects of this disruption in the classroom due to frequent repairs and high humidity.

French teacher Heidi Florian’s room in particular bears the brunt of these recurring system failures.

“Our classroom’s AC has been unreliable since the spring of 2024,” Florian said. “It will get fixed and work for some amount of time, for a week to a month, and then it breaks again.”

Florian said working around the unpredictable breakdowns has hindered the effectiveness of her teaching as she is forced to pick up the lesson and leave the classroom without notice.

“It’s hard to plan, because I might be expecting to stay in the room one day and I show up and I have to change my plans at the last minute.” Florian said. “If I want to go through the answers to questions or something like that, I end up running from table to table, and obviously the potential for distraction is much higher because somebody’s walking by and the kids are wanting to say hi to their friends.”

Junior Juliette Tannoux-Rondon, along with other classmates, has been solely doing individual assignments when the class usually assigns many group projects, due to a lack of a consistent classroom setting.

“I feel like we haven’t done any projects or videos lately,” Tannoux-Rondon said. “We haven’t done anything on the board for a while since all the instructions have to be really quick, and then we have to get out of the room.”

The scope of these effects are mirrored across the city, with Houston Independent School District reporting more than 1,600 heating, ventilation and air conditioning problems in the final full month of 2024-25 school year, according to the Houston Chronicle.

Many point to the city’s transportation system as the catalyst of Houston’s already hot and humid climate. Pre-AP Biology teacher Sudhiva Samant described Bellaire’s recent changing temperatures as a direct effect of this infrastructure.

“In Houston, every member of the family drives a car, and the heat has been increasing year by year,” Samant said. “Two years ago, we were out with our hoodies and sweaters by September, but now, we don’t take them out until January. I think what Houston has to do is, number one, get a good transportation system.”

Bellaire students have similar ideas, urging for the switch from private to public transport.

“We can drive less by taking walks and biking, which use less fossil fuel,” Hassid said. “We should balance the amount of people that drive cars everyday and use public transportation, to limit the amount of fuel we produce.”

However, Houston’s highway system constrains sustainability attempts. Walking and biking often aren’t a first choice when current infrastructure and busy lifestyles encourage highways and car lanes. Compared to cities like New York, where the subway system is the most preferred method of transportation, integrating a similar structure will look entirely different in a city like Houston.

But that doesn’t stop people from acting now. “Students have a great voice,” Patel said. “They can lead by example, by showing us that they are making change.”

The 2025 insight of statistics by the Potsdam Institute is affecting how people in and out of Bellaire are noticing and responding to climate change.

“I think that it’s very scary how high these [statistics] are, because they just keep going up,” Hassid said. “Our world is for us. We live here, and we can’t ruin it. We need to protect it.”
