Planet-heating methane spewing into the atmosphere from the damaged Nord Stream pipelines only has a modest impact on climate change, say scientists, but sharply highlights the risks of fossil-fuel-driven greenhouse gas emissions.
Gas emanates from a leak measuring more than 950 meters in diameter on the Nord Stream 1 gas pipeline in the Baltic Sea.
With only rough estimates available as to how much natural gas might bubble up through the Baltic Sea, scientists expressed concerns about climate and environmental impacts – but stressed that the amounts of methane involved were a tiny fraction of global emissions. Methane is responsible for roughly 30 percent of the global rise in temperatures to date, even though it is far less abundant in the atmosphere than COThis is the subject of much uncertainty, although some experts and organizations have attempted to calculate the potential amount of gas in the pipelines.
Paul Balcombe, an honorary lecturer at the Department of Chemical Engineering at Imperial College London, said estimates for the gas in the pipes range from around 150 to 300 million cubic meters.But he added if just one of the pipes did completely empty out it would be about twice as much as the worst methane leak recorded in the United States, the 2015 Aliso Canyon leak.
