Boreal regions of Alaska are home to an interesting phenomenon of ‘boiling’ lakes. They can also be found in Canada, Siberia, and a few other northernmost places. The bubbles that appear in the lakes are created by gas methane, which is seeping out. According to some scientists, this is the result of global warming. Once frozen ground began to melt and released the gases that have been trapped inside since the Ice age.
When the methane bubble pops, it exposes the gas into the atmosphere. The methane released by one lake can’t have much effect, but combining with others factors across the world it brings lots of damage. It can change our climate really fast.
At some lakes methane is seeping out continuously. During summer months, the bubbles float on the surface of the lake and pop. As the lakes freeze in fall and winter, the gas is trapped under the ice. During this period the researchers and scientists can see the exact places where the gas seeps out. Methane creates spectacular patterns on ice, which are clearly visible. The scientists pop the ice in such places and test it with a lighter. When the place is right, you can see enormous flames bursting into the air. But don't try it yourself, since it's very dangerous.
If you want to see the experiments with your own eyes, come to Fairbanks in Alaska during fall months between October and November, when the ice is thick enough and the snow hasn’t spoiled the visibility yet. Or choose small ponds in tundra or small river branches.
Practical info
Where are the methane bubbles located in Alaska?
Methane bubbles are found in the boreal regions of Alaska, in the lakes, small ponds in tundra, or small river branches. They occur when gas is released from the ground, creating bubbles under the ice. This phenomenon can be witnessed by visiting Fairbanks during October and November. It is best to choose areas where the snow hasn't spoiled visibility yet. Show more
What is the ideal time to observe the methane bubbles in Fairbanks?
Late fall months of October and November are the best time to observe the methane bubbles in Fairbanks. During this time, the lakes begin to freeze, trapping the gas under the ice, which remains intact until it melts the following summer, releasing the gas once again. The timing is ideal to witness the patterns of methane bubbles rising to the surface. Show more
What is the reason behind the occurrence of methane bubbles in the lakes?
Methane bubbles in the lakes are a result of gas seeping out of the ground. The melting of frozen ground causes the release of trapped gases that have been isolated since the Ice age, creating boiling lakes. Methane is produced by bacteria breaking down organic matter in low-oxygen environments. This phenomenon is linked to global warming and environmental changes. Show more
How can the methane bubbles potentially affect global climate change?
Methane is a potent greenhouse gas, trapping heat about 25 times more effectively than carbon dioxide. The current rate of methane bubble seepage has the potential to significantly impact global climate change, accelerating climate warming and causing further environmental damage. Methane also reacts with other chemicals in the atmosphere, leading to the production of smog and air pollution. Show more
Is it safe for tourists to witness the methane bubbles?
Witnessing the methane bubbles is safe if you follow the guidelines by the authorities, and refrain from attempting to conduct experiments by yourself. The bubbles can create spectacular patterns on ice, and researchers and scientists often pop the ice to test the gas with lighters and observe the flames. However, it can be dangerous to try this without proper safety measures as flames can get really high. Show more
