About this episode
Methane in the Atmosphere: A Serious RiskMany of the solutions we often hear about when it comes to reducing greenhouse gas emissions revolve around reducing carbon emissions, as carbon dioxide (CO2) is the primary greenhouse gas emitted by human activities. Methane, however, is the second most common greenhouse gas, emitted through agricultural practices, landfill waste, coal mining, and oil and gas operations. While methane generally receives less attention than carbon dioxide when it comes to climate solutions, recent studies have shown that it is a more potent greenhouse gas than carbon dioxide. According to the United Nations Economic Commission for Europe, methane has a global warming potential 28-34 times higher than CO2 upon emission, which increases to 84-86 times over a 20-year period. How does methane enter our skies?The concentration of methane in the atmosphere has more than doubled over the past century. Both everyday infrastructure in older cities and major leaks at oil and gas fields add to the quantity of methane into the atmosphere. As for the source of these leaks, they are largely caused by equipment failures or faulty pipes and vessels. 2,595 gas incidents have been reported in the US from 2010 to 2021, adding up to 26.6 billion cubic feet of methane gas emitted. Methane impacts both the climate system and public health; breathing methane can cause damaged airways, lung diseases, asthma attacks, increased rates of preterm birth, cardiovascular morbidity and mortality, and heightened stroke risk. What can we do?Mining operations can be improved to reduce methane leaks and oil and gas operations can greatly reduce emissions throughout the system. As our tools of measurement and technology improve, the world has realized the greater need to attack methane emissions, which led to the Global Methane Pledge in 2021. In this pledge, 158 countries and the EU pledged to make a distinct effort to reduce global methane emissions by at least 30 percent from 2020 levels by 2030. Part of reducing methane emissions involves switching from fossil fuels to electricity generated from renewable sources. According to Environmental specialist and Stanford professor Dr. Rob Jackson, our skies will become cleaner once we switch to cleaner, electrical energy sources, including electric heat pumps to cool and heat our homes, electric water heaters, and especially electric stoves.
