What environmental-climate impact will the Nord Stream accident have?

The disaster of the explosions resulting in the leakage of gas from the Nord Stream pipeline will have a devastating economic impact, but also a very severe environmental impact that is still difficult to quantify. A total of four gas leaks were discovered after the explosions of the Nord Stream 1 and 2 pipeline lines, the Swedish Coast Guard said.

Two of these four losses are in the Swedish economic zone. On the NATO incident he expresses deep concern and in a note also signed by Sweden and Finland, he stresses that all the information currently available indicates that it is the result of deliberate, reckless and irresponsible acts of sabotage.

NATO also notes that it is ready to respond unitedly and with determination to any deliberate attack against the critical infrastructures of the allies. Nord Stream AG explained on its online site: "Until the damage assessment is completed, it is impossible to predict the recovery times of the gas transport infrastructure.

Entry into the accident area can only be allowed after pressure in the pipeline will be stabilized and gas leakage stopped." Regarding the Climate Impact, Greenpeace writes: "The potential climate impact of the methane spill from Nord stream 1 + 2 could be 30 million tons of CO2 equivalent over a period of 20 years.

Equal to the annual emissions of 20 million cars. in the EU. " Nord Stream pipelines may never work again. Lines 1 and 2 linking Russia to Europe have been severely damaged by suspicious explosions off the Danish Baltic island of Bornholm.

Among the hypotheses, the hit of a submarine, a marine drone or TNT charges. Some scientists, such as those from the German environmental organization Deutsche Umwelthilfe or the University of Colorado biogeochemistry expert Joe von Fischer, interviewed by New Scientist, believe that the leaked gas will have a limited impact on greenhouse gases in the atmosphere precisely because it is of subsea leaks: "When methane is released at the bottom of a very deep basin, it is almost completely oxidized by the methanotrophic bacteria present in the water column."

According to Grant Allen, environmental scientist with expertise in natural gas and atmospheric composition at the University of Manchester, the leaks could be so huge and the gas column in the water so pure and violent that it would be difficult for bacteria to do any mitigating action.
