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.)
