Fracking Linked to Miscarriages, Birth Defects and Infertility

As the level of concern about fracking rises—what chemicals are being used in these "unconventional oil and gas (UOG) operations, whether they are getting into the water and air, and whether information on them is being withheld from communities—a new study adds more evidence that the concern is justified. It asserts that fracking increases the rate of miscarriage, as well as other reproductive and developmental problems.

"In this work," the six researchers from the Center for Environmental Health (CEH), the University of Missouri and the Institute for Health and the Environment say, "we review the scientific literature providing evidence that adult and early life exposure to chemicals associated with UOG operations can result in adverse reproductive health and developmental effects in humans."

“Children, developing fetuses, they’re especially vulnerable to environmental factors,” said CEH's Ellen Webb, the study's lead author. “We really need to be concerned about the impacts for these future generations.”

The study points out that fracking operations have the potential to pollute the air and water of nearby communities, and "every stage of operation from well construction to extraction, operations, transportation and distribution can lead to air and water contamination" from hundreds of chemicals. It looks at what chemicals are used in fracking, the ways in which they can find their way into the air and water, and the adverse reproductive and developmental effects they are associated with.

Looking at more than 150 papers that analyzed the health effects of compounds and chemicals widely used in fracking, such as benzene, toluene, ethyl benzene, xylene, formaldehyde and heavy metals such as arsenic, cadmium and lead, they identified a range of associated defects and reproductive disruptions known to be associated with exposure to them.

"Research shows that there are critical windows of vulnerability during prenatal and early postnatal development, during which chemical exposures can cause potentially permanent damage to the growing embryo and fetus," the study said. "Many of the air and water pollutants found near UOG operation sites are recognized as being developmental and reproductive toxicants; therefore, there is a compelling need to increase our knowledge of the potential health consequences for adults, infants and children from these chemicals through rapid and thorough health research investigation."

Among the problems the study identified are infertility, miscarriage, impaired fetal growth, low birth weight, preterm birth and birth defects, and it found that rates of these conditions were elevated in heavily fracked areas. It also found many of the same problems in farm animals and pets living in those areas.

Pointing out the dramatic growth in fracking, how commonplace spills and leaks are and the links between the chemicals used in fracking and human health outcomes, the authors advised caution in expanding UOG operations.

"Our heartfelt concern is that if the oil and gas industry continues to develop more wells, then the problem is going to be exacerbated greatly before we finally have answers,” study co-author Dr. Sheila Bushkin-Bedient, told U.S. News & World Report. “In terms of chronic diseases and in terms of finding out the developmental problems of babies, we might not know that for a decade or two. We might not know about cancers for a couple of decades, and by that time, it would be too late.”

While oil and gas industry trade group Energy in Depth pooh-poohed the findings and claimed that all the studies on which they are based have been debunked, Webb said, “Federal and state regulators must not ignore the potential serious health impacts from chemicals for families living in close proximity to fracking and other UOG sites. This growing evidence of health concerns for parents and children suggests that there is an urgent need to halt fracking and evaluate the adverse potential health outcomes for these communities on the front lines of the growing fracking industry.”

The Past 5 Years Were the Arctic's Warmest on Record

The Arctic is still warming at twice the rate of anywhere else on Earth, and the region's air temperatures in the past five years between 2014-2018 have exceeded all previous records since 1900, according to a peer-reviewed report released by the U.S. National Oceanographic and Atmospheric Administration (NOAA) on Tuesday.

The agency's 13th annual Arctic Report Card also concluded that 2018 was second only to 2016 in terms of the region's overall warmth.

3 Key Dangers of Solar Geoengineering and Why Some Critics Urge a Global Ban

By Justin Mikulka

A Harvard research team recently announced plans to perform early tests to shoot sunlight-reflecting particles into the high atmosphere to slow or reverse global warming.

These research efforts, which could take shape as soon as the first half of 2019, fall under the banner of a geoengineering technology known as solar radiation management, which is sometimes called "sun dimming."

Report: Current Climate Policies Will Warm the World by 3.3˚C

This past October, a widely disseminated United Nations report warned that far-reaching and significant climate impacts will already occur at 1.5˚C of warming by 2100.

But in a study released Tuesday, researchers determined that the current climate polices of governments around the world will push Earth towards 3.3˚C of warming. That's more than two times the aspirational 1.5˚C target adopted by nearly 200 nations under the 2015 Paris agreement.

The Lesson From a Burning Paris: We Can’t Tax Our Way Out of the Climate Crisis

By Wenonah Hauter

The images from the streets of Paris over the past weeks are stark and poignant: thousands of angry protesters, largely representing the struggling French working class, resorting to mass civil unrest to express fear and frustration over a proposed new gas tax. For the moment, the protests have been successful. French President Emmanuel Macron backed off the new tax proposal, at least for six months. The popular uprising won, seemingly at the expense of the global fight against climate change and the future wellbeing of our planet.
