As a specialist in environmental health and toxicology, I would like to address the question of whether methane is bad for your health. Methane, CH4, is a colorless, odorless, and highly flammable gas that is the primary component of natural gas. It is also one of the greenhouse gases that contribute to the greenhouse effect and climate change. However, the direct health effects of methane on humans are not as pronounced as some other pollutants, but it can still pose risks under certain conditions.
Firstly, it is important to understand that methane is not toxic in the traditional sense; it does not cause direct harm to human health through inhalation at the concentrations typically found in the environment. However, the presence of methane can indicate a lack of oxygen in the air, which can be dangerous if the levels of oxygen drop too low. Prolonged exposure to an oxygen-deficient atmosphere can lead to asphyxiation and death.
Moreover, methane itself is not a significant contributor to air pollution or respiratory problems. However, it can be associated with other pollutants that are harmful. For example, in the process of natural gas extraction and usage, methane can be accompanied by volatile organic compounds (VOCs) and other toxic gases such as benzene, toluene, ethylbenzene, and xylene (BTEX). These substances can have adverse health effects, including respiratory issues, neurological damage, and cancer.
Another concern with methane is its role as a greenhouse gas. While it does not directly harm human health, the indirect effects of methane on the environment can have significant health implications. Methane is approximately 25 times more effective at trapping heat than carbon dioxide over a 100-year period. This potent greenhouse effect can exacerbate global warming, leading to a range of health issues associated with climate change, such as heat-related illnesses, respiratory problems from worsening air quality, and the spread of vector-borne diseases.
Furthermore, methane can be a byproduct of various industrial processes and agricultural activities. In these settings, it can contribute to occupational health risks for workers who are exposed to high concentrations of methane. In enclosed spaces, such as mines or landfills, methane can accumulate and pose a risk of explosion, which can lead to serious injuries or fatalities.
It is also worth noting that methane can be vented into the atmosphere from various natural and human-made sources, such as wetlands, rice paddies, livestock, and leaks from natural gas infrastructure. When methane is vented into the atmosphere, it contributes to the greenhouse effect, as mentioned earlier. This process can create a feedback loop where global warming leads to the release of more methane, which in turn amplifies the warming effect.
In summary, while methane itself is not directly harmful to human health at typical environmental concentrations, it can indicate oxygen deficiency, be associated with other harmful pollutants, and contribute to the greenhouse effect and climate change, which has broader health implications. It is also important to consider the occupational health risks in industries where methane is a byproduct.

By venting methane into the atmosphere, the lakes are amplifying the global warming that created them: Methane is a potent greenhouse gas. Carbon dioxide is the main one, because the atmosphere holds 200 times as much of it. But a given amount of methane traps at least 25 times as much heat--unless you burn it first.
