Revealed: 1,000 super-emitting methane leaks risk climate tipping points

More than 1,000 human-caused "methane super-emission events" have been detected in 2022, according to new figures reported on the Guardian's front page. The paper notes that most of the events came from oil and gas fields. It continues: “Methane super-emitting locations were identified by analysis of satellite data, with the US, Russia and Turkmenistan responsible for the largest number of fossil fuel installations. The largest event was a spill of 427 tons per hour in August near Turkmenistan's Caspian Sea coast and a major gas pipeline. This single leak was equivalent to the emission rate of 67 million cars, or the hourly national emissions of France." Meanwhile, separate data reveals 55 "methane bombs" - defined as "fields where the leakage from full resource use alone would result in emissions equal to at least a billion tonnes of CO2 " – is stated in the document. He says more than half of those fields are already in production — including the three largest, all of which are in North America. He adds: "According to a recent estimate of the global carbon budget, methane bomb emissions are also significantly higher than the emission limit of 380 billion tonnes of CO2 from all sources needed to keep global warming below 1.5°C." These datasets show that addressing leakage from sites with fossil fuels is the fastest and cheapest way to reduce methane emissions, the paper says. Newspaper they inform separately on the impact of the "Pennsylvania Climate Disaster"—one of the super-emitter events in the main investigation—on the local community.
