YT comments can be aggravating, but I read them anyway because occasionally some interactions are rewarding.

I noticed in the comments on this video there seem to be a number of people who claim that burning methane only emits CO2.

Here is my response:

Burning methane at high temperatures causes a reaction between nitrogen and oxygen in the air which produces nitrogen oxides, including nitrogen dioxide.

Another commenter got into a dispute with me about the exact temperature of combustion in these specific turbines - so I looked into it. TIME magazine did an investigation and asked Univ of Tenn Knoxville researchers to measure air pollution levels around the facility using satellite data. Quote from the article: "They found that average concentrations of nitrogen dioxide have increased by 3% when comparing the periods before June 2024 and afterward. They also found that peak nitrogen dioxide concentration levels have increased by 79% from pre-xAI levels in areas immediately surrounding the data center, and by 9% in nearby Boxtown.

Because high concentrations of air pollutants pose greater health risks than lower concentrations, the researchers said, focusing on these spikes—rather than just averages—offers more meaningful insight into potential health impacts. "

Typically, scrubbers are installed at gas power plants to reduce nitrogen oxide emissions. An article from CNBC reported : "While xAI had previously told Memphis regulators that its turbines would include state-of-the-art pollution controls, known as selective catalytic reduction technology, its supplier, Solaris Energy Infrastructure
told CNBC in June that it did not install such controls in xAI’s “temporary” turbines."

London Begins to Breathe Better

[Read on Ethical Revolution]

A study by the Greater London Authority has shown that the city’s levels of lethal pollutants have substantially decreased since the expansion of the UK capital’s ultra low emission zone (Ulez).

The London-wide zone covers nine million people across 1500 km2, the world’s largest zone of its kind.

The report shows that not only have deprived areas seen some of the biggest improvements but air quality has improved in all areas and at a faster rate than the rest of the country.

Nitrogen dioxide is down 27% since Ulez first came in in 2019. PM2.5’s (small particle emissions) are down 31% in outer London compared to what would have been without the Ulez expansion.

Speaking to the Guardian, Mayor of London, Sadiq Khan said, “When I was first elected, evidence showed it would take 193 years to bring London’s air pollution within legal limits if the current efforts continued. However, due to our transformative policies we are now close to achieving it this year.”

Industry Knew—and Hid—Dangers of #GasStoves Over 50 Years Ago

Brett WilkinsMar 07, 2023

"Newly uncovered documents published last week by #DeSmog reveal that the leading #GasIndustry trade group knew over 50 years ago that cooking with gas stoves could harm human #health and tried to cover up the evidence.

"The DeSmog revelations regarding the #AmericanGasAssociation (AGA) came as the gas industry is pushing back against climate and public health advocates' efforts to ban new gas stoves amid mounting scientific evidence that the appliances threaten the warming planet and people's health.

"Recent studies—which, among other things, showed that #NitrogenDioxide, #CarbonMonoxide, and ultrafine particles produced by gas stoves cause a range of health problems, including 1 in 8 U.S. cases of childhood #asthma—sparked fast and furious backlash from the gas industry and its congressional boosters.

"'It's less widely known that the gas industry has long sponsored its own research into the problem of indoor air pollution from gas stoves,' wrote DeSmog's Rebecca John. 'Now, newly discovered documents reveal that the American Gas Association was studying the health and indoor pollution risks from gas stoves as far back as the early 1970s—that they knew much more, at a far earlier date, than has been previously documented.""
