New Study Now Claims We Humans Heat The Atmosphere Just By Exhaling

“Where hydrocarbon chains (food types) are consumed by humans and turned into CH4 [methane] … global warming potential is no longer neutral, and human respiration has a net warming effect on the atmosphere.”  – Prada et al., 2023

According to a new study, humans “contribute to global warming” by exhaling greenhouse gases like methane and carbon dioxide 16 times per minute.

“Exhaled human breath can contain small, elevated concentrations of methane (CH4) and nitrous oxide (N2O), both of which contribute to global warming. These emissions from humans are not well understood and are rarely quantified in global greenhouse gas inventories.”

Like bovine populations, humans are referred to as “methane producers” (MPs), respiring and burping this potent greenhouse gas simply by existing. (Concerns about methane’s global warming potential are so significant that New Zealand is imposing a “methane tax” on the nation’s cows, as these MP animals are heating up the planet with their burps.)

Measurements of methane and nitrous oxide in human breath and the development of UK scale emissions

In a recent study published in PLOS ONE, titled “Measurements of methane and nitrous oxide in human breath and the development of UK scale emissions,” researchers have embarked on a quest that epitomizes the absurdity of current climate change discourse. This study, focusing on the emissions of methane (CH4) and nitrous oxide (N2O) from human breath, is not only a glaring example of scientific overreach but also a worrying indicator of the lengths to which climate alarmism is willing to go.

The study’s objective to investigate emissions from human breath in the UK population is fundamentally flawed. It operates under the assumption that these emissions are significant enough to warrant detailed analysis and inclusion in national greenhouse gas inventories. This premise is laughable at best, considering the minuscule percentage these emissions contribute to the overall greenhouse gas emissions.

The methodology employed in the study is questionable. Collecting 328 breath samples from 104 volunteers hardly constitutes a representative sample of the UK population. Furthermore, the study’s reliance on such a small sample size to draw conclusions about national-scale emissions is a classic case of over-extrapolation.

The study’s findings that 31% of participants were methane producers and that all participants emitted nitrous oxide are presented without adequate context. These results are portrayed as significant, yet they fail to consider the broader environmental impact. The fact that these emissions are stated contribute a mere 0.05% and 0.1% to the UK’s total emissions of CH4 and N2O, respectively, well below any margin of error in “national inventories” renders these findings insignificant.
