Hurricanes can triple the amount of toxic contamination released into nearby communities
A new study in Environmental Science and Technology found that petrochemical manufacturers and refineries in Texas released higher amounts of toxic contamination during hurricanes.
In short:
- Compared to periods of normal weather, Hurricane Rita (2005) resulted in twice as many contamination releases, while Hurricanes Ike (2008) and Harvey (2017) caused releases to triple.
- Communities with a higher percentage of renters, higher poverty rates, and more Hispanic residents were more likely to experience an increase in contamination.
- Petrochemical refineries were responsible for the highest amount of contamination released during hurricanes.
Key quote:
“Low-income communities and people of color are disproportionately impacted by hurricanes and floods, leading to concerns that climate change will further exacerbate existing environmental health disparities.”
Why this matters:
As climate change continues to alter global weather patterns, extreme weather events such as hurricanes are becoming more common and more severe. With hazardous petrochemical sites disproportionately located within low-income communities of color, this study highlights how extreme weather can have significant environmental justice implications, as well as the need for better protections for fenceline communities.

Climate change linked to an increased risk of cardiovascular issues, including death
In short:
- An increased risk of cardiovascular disease was specifically linked to extreme temperatures, ground-level air pollution, hurricanes, cyclones, and dust storms.
- In some cases, experiencing a combination of stressors (such as pollution and high temperatures) amplified the risk.
- Older adults, individuals from minority groups, and those in low income communities were disproportionately affected by these stressors.
Key quote:
“Urgent action is needed to reduce greenhouse gas emissions and lower climate change–associated cardiovascular risk in vulnerable populations.”
Why this matters:
As climate change continues to alter global weather patterns, the environmental consequences examined in this article are becoming more common and more intense. With international climate agreements like COP28 failing to definitively address fossil fuels and other drivers of global warming, the authors emphasize the need to recognizethe human health impacts of climate change as a way to push for concrete action.

Wildfires and heat waves linked to an increased risk for preterm birth
Pregnant Californians exposed to extreme climate events like wildfires and heat waves were at a higher risk for giving birth early, according to a new study published in Environmental Research.
In short:
- Exposure to wildfires was associated with an increased chance of preterm birth. The same was true for days with unusually high temperatures.
- This association was much stronger when exposure to both wildfires and heat waves occurred simultaneously.
- The risk for preterm birth was strongest for Black, Hispanic, Asian, and Native American study participants in comparison to White participants.
Key quote:
“Given the increasingly frequent occurrence and co-occurrence of these climate related events, pregnant people and their growing fetuses should be consistently in the front of climate adaptation and mitigation efforts.”
Why this matters:
As climate change continues to impact global weather patterns, heat waves and wildfires have become increasingly intense and frequent. Environmental hazards that affect the health of pregnant people and their children can have long-term and severe outcomes, such as harm to babies’ respiratory, neurological, and cardiometabolic development. The authors of this study point to the need to recognize pregnancy as a vulnerable period in order to encourage regulatory action that better protects parents and their children.
