Paper For Above instruction

The debate over whether hydraulic fracturing, commonly known as fracking, contributes to global warming comprises two contrasting perspectives. Passage 1 argues that fracking significantly contributes to climate change, primarily through the release of methane gas, a potent greenhouse gas. Passage 2 counters that fracking does not substantially impact global warming, citing scientific studies showing low methane emissions from fracking operations. This essay will examine both positions, analyze the evidence provided, and evaluate which argument appears more convincing based on the presented information.

Analysis of the Pro-Position

In Passage 1, Louis W. Allstadt emphasizes that fracking has become a necessity because most conventional oil and gas reservoirs have been exploited. He notes that traditional extraction relied on natural pressure in porous rock formations, which allowed for relatively contained extraction. However, as these reservoirs diminish, the industry turns to unconventional methods like fracking in shale and tight sand formations, which require extensive use of fracking fluids. Allstadt highlights that this process involves significantly larger volumes of fluids and flowback—up to 100 times more than conventional wells—and that the geological conditions above the target zones are more permeable, increasing the risk of methane leakage. He also points out documented cases where methane has escaped into aquifers and atmospheres, sometimes through old well bores or natural fissures, raising concerns about clandestine emissions. The core argument is that fracking creates pathways for methane—a powerful short-term greenhouse gas—to seep into the environment over time, exacerbating global warming. The evidence underscores that methane’s potency as a greenhouse gas is enough to make fracking a serious climate concern, especially considering that these emissions may be underestimated and ongoing.

Analysis of the Con-Position

In contrast, Passage 2 presents a scientific study published in the Proceedings of the National Academy of Sciences which claims that fracking does not significantly contribute to global warming. Coral Davenport reports that the study, funded by energy companies including ExxonMobil and an environmental group, analyzed methane emissions from various gas production sites across the United States. The study found that modern surface equipment reduces methane emissions by 99 percent and that overall emissions are about 10 percent lower than levels set by the EPA. It further states that most fracking sites have measures in place to prevent methane leakage, and the few instances where emissions exceeded standards are exceptions rather than the norm. The evidence suggests that technological advancements and regulatory measures have effectively minimized methane escapes, thereby limiting fracking’s impact on climate change. The focus is on the data collected through extensive field measurements, asserting that recent findings negate strong links between fracking and global warming.

Comparison and Evaluation

When comparing both perspectives, the pro-position provides a cautionary stance that emphasizes the environmental risks associated with increased methane emissions due to fracking. It highlights potential long-term consequences of creating new pathways for methane to escape into the atmosphere, thereby contributing to the greenhouse effect. The supporting evidence draws from documented cases and the technical aspects of fracking operations showing potential for leaks. However, this argument might be limited by the challenge of quantifying the total methane emissions over time, which remains uncertain.

The con-position bases its argument on recent scientific research suggesting that advancements in technology have substantially reduced methane leaks, with current emissions being lower than regulatory thresholds. This perspective benefits from empirical data and rigorous field measurements, increasing credibility. Nonetheless, critics might argue that this study, while comprehensive, might underestimate the cumulative or long-term impacts of methane seepage that are difficult to measure in short-term studies.

Considering the evidence, the more convincing position seems to be the pro-argument. This stance appropriately underscores the potential environmental hazards inherent in fracking, especially in light of documented methane escapes and the recognition that existing measurements might underestimate emissions in the long run. While technological improvements are promising, the uncertainty surrounding the long-term integrity of fracking operations and the creation of new vent pathways suggest that fracking could indeed pose a risk to global climate stability. Thus, precautionary caution is warranted in examining fracking’s role in climate change.

Conclusion

The controversy over fracking’s contribution to global warming hinges on the interpretation of scientific data, technological efficacy, and risk assessment. While recent studies suggest mitigated emissions, the fears articulated in Passage 1 about the potential for methane leaks and the environmental harm from such pathways remain compelling. Given the complexity and the potential for underestimation, a precautionary approach that considers the worst-case scenarios appears more prudent. Therefore, it is essential to continue monitoring, regulating, and researching fracking to better understand its full impact on the environment and climate, rather than dismissing concerns prematurely.
