Trump's push for more drilling clashes with market realities

Despite Donald Trump's efforts to expand offshore drilling, oil companies are sitting on thousands of unused leases in the Gulf of Mexico due to high costs and an oversupply of crude.

Tristan Baurick reports for Grist and Verite News.


In short:

  • Of the 2,206 active offshore leases in the Gulf, only 448 are producing oil, with companies reluctant to drill due to low prices and high costs.
  • Trump's regulatory rollbacks and expanded leasing won't significantly increase production, as the U.S. already produces record amounts of crude.
  • Industry experts say many leases are held for speculation, investment or competitive advantage rather than immediate drilling.

Key quote:

“It’s not the regulations that are getting in the way, it’s the economics.”

— Hugh Daigle, professor of petroleum engineering at the University of Texas at Austin

Why this matters:

Trump’s aggressive push for deregulation was widely championed by the oil and gas industry as a way to ease financial burdens and increase domestic energy output. But experts say those rollbacks, while potentially lucrative for fossil fuel companies, are unlikely to meaningfully boost production or lower consumer energy costs. The balance between energy independence, corporate profits and environmental stewardship continues to shape policy debates as the country navigates a future of volatile oil markets and growing climate concerns.

Increased autism risk linked to exposure to wildfire smoke during pregnancy

In a first-of-its-kind study published in Environmental Science and Technology, researchers found that mothers who were exposed to wildlife smoke during the third trimester of pregnancy were more likely to have children diagnosed with autism by age 5.


In short:

  • More frequent exposure to wildlife smoke during pregnancy was associated with a higher risk of autism in children.
  • The study analyzed more than 200,000 mother-child pairs in Southern California between 2006 to 2014; nearly 60% of them were exposed to wildfire smoke for more than 5 days during pregnancy.
  • The authors also found that prenatal exposure to particulate matter air pollution from a variety of sources — not just wildfires — is associated with an increased risk of autism in children.


Key quote:

“As climate change increases the frequency and intensity of wildfires in many parts of the world, understanding their relationship with autism is important to being able to develop preventive policy and interventions that will protect pregnant women and their children.”

- Study co-author Mostafijur Rahman, via Tulane University’s accompanying press release


Why this matters:

As climate change continues to impact global weather patterns, wildfires have become increasingly intense and frequent. Their impact on air pollution is significant - in California, wildfires account for over 70% of the fine particulate matter exposure on days with poor air quality. Environmental hazards that affect the health of pregnant people and their children can have long-term and severe outcomes. The authors of this study underscore the need for policies that protect vulnerable populations from air pollution and reduce the inequality in its health impacts.
