Mysterious Methane Leak Perplexes Scientists in Baltic Sea

Scientists in Sweden have discovered a large and unusual methane leak in the Baltic Sea, estimated to be around 20 square kilometers in size. The leak is releasing bubbles of methane that are making their way to the surface. Methane is a potent greenhouse gas and is responsible for about 30% of the global rise in temperatures. The researchers believe that the oxygen-free conditions in the deep water of the Baltic Sea may be allowing the bubbles to retain more methane, making their transport to the surface more efficient. The team also suspects that there may be similar leaks in other areas of the Baltic Sea.
