Methane Might Be a Bigger Climate Problem Than Thought, Study Finds
NY Times – Sep 29
Because methane is a stronger, though shorter-lived, greenhouse gas than carbon dioxide, efforts to identify and reduce methane emissions have intensified in recent years.
Methane is the primary component of natural gas, also known as fossil gas, which can leak into the atmosphere from wells, pipelines and other infrastructure, and is also deliberately released for maintenance or other reasons.
But vast amounts are flared.
Gas that is flared is often produced with oil at wells around the world, or at other industry facilities. There may not be a pipeline or other means to market it economically, and because it is flammable, it poses safety issues. In such cases, the gas is sent through a vertical pipe with an igniter at the top, and burned.
The International Energy Agency estimated that worldwide in 2021, more than 140 million cubic meters of methane was burned in this way, equal to the amount imported that year by Germany, France and the Netherlands.
If the combustion is efficient, almost all of the methane is destroyed, converted into carbon dioxide, which has less of an immediate climate impact. The Environmental Protection Agency, in studies conducted in the 1980s, calculated that flares destroyed 98 percent of the methane sent through them.
But the new research found that flaring was actually far less effective, especially when unlit flares were taken into account. Emissions from improper flaring accounted for as much as 10 percent of all methane emissions in the oil and gas industry, the scientists said. The findings were published in the journal Science. …
Methane has more than 80 times the warming power of carbon dioxide over the first 20 years after it reaches the atmosphere. Even though CO2 has a longer-lasting effect, methane sets the pace for warming in the near term. At least 25% of today’s global warming is driven by methane from human actions.
Cutting methane emissions …
(Of course, much of that is from bovine flatulence, which no one is ever going to do anything about, alas.)
