At the time of the leak, Jeffrey Kargel, a senior scientist at the Planetary Research Institute in Tucson, Arizona, told POLITICO that “the leak was really disturbing.” However, while the amount of gas lost “is obviously large … it is not a climate catastrophe as one might think,” Kargel said.
Germany, Sweden and Denmark launched separate investigations into the incident. The three of them found out that it was due to and it was due to sabotage.
Several countries have been publicly blamed for the explosions with varying degrees of evidence. Ukraine said Russia was behind the bombing, and Poland also suggested Moscow was responsible, which the Kremlin denied.
In early March, German media reported that German prosecutors had found “traces” evidence suggesting that Ukrainians may have been involved in the explosions that blew up the Nord Stream gas pipelines. However, these reports emphasized that there was no evidence that Ukrainian authorities ordered or participated in the attack.
An earlier report by The New York Times said that “intelligence suggests a pro-Ukraine group” sabotaged the pipelines.
