Methane emissions hit-all-time high, scientists say


Methane is a major source of gas emissions in cows, which researchers say reached a record high in 2017.

  • Methane is a more powerful greenhouse gas than carbon dioxide.
  • It is produced by livestock, natural gas, oil and other sources.
  • While carbon dioxide decreased during the coronavirus epidemic, methane was unlikely.

Methane emissions, a powerful component in global warming, have hit a record high, putting 350 million more cars on the world’s roads, according to a new research.

Abandoned, methane emission levels may help heat the Earth to dangerous temperatures before the end of the century. According to the news release, it would not allow any opportunity to limit global temperature rise to more than 2.7 degrees per year. From Stanford University that details the research.

result The study conducted by scientists from several institutions including NASA, Yale and Stanford was published on Tuesday.

Researchers found that methane emission levels reached their highest point between 2000 and 2017, for which the most recent year of data is available. Emissions of methane are largely from coal mining, oil production, natural gas production, landfills, and cattle and sheep.

Rob Jackson, a Stanford study writer, said in a news release, “The use of natural gas is increasing rapidly here in the US and globally. It is replenishing coal in the power sector and reducing carbon dioxide emissions, But methane is increasing emissions in the region. ”

“As a result, we are emitting more methane from oil and gas wells and seepage pipelines.”

He also said that livestock is a major source where people can laugh about it.

“The emissions of cattle and other ruminants are almost larger than the fossil fuel industry for methane,” Jackson said. “People joke about burying cows without realizing how big a source they really are.”

“Methane does not last as long in the atmosphere as carbon dioxide, but is much more efficient When trapped by carbon dioxide in heat, “Benjamin Poulter, a research scientist at NASA’s Goddard Space Flight Center and another author on the study, told NBC News.

Methane ingress can be slow if fossil fuel usage is reduced, leaks from pipelines and wells are curbed and changes are made to how humans grow, grow and eat our food.

“We will need to eat less meat and reduce emissions associated with cattle and rice farming,” Jackson said, “and replacing oil and natural gas in our cars and homes.”

New innovations such as algae feed supplements to reduce cows’ sacks and use drones to monitor methane leaks from oil and gas wells may also help to dent methane emissions.

And during carbon emissions during coronovirus restrictions that limited transportation and manufacturing resulted in carbon emissions, Jackson said there was little impact on methane.

“There is no chance that methane emissions dropped as much as carbon dioxide emissions caused by the virus,” he said. “We are still heating our homes and buildings, and agriculture keeps growing.”
