NASA Discovers Bubbling Lakes In The Remote Arctic - A Sign Of Global Warming

NASA has released videos of bubbling lakes in the remote Arctic tundra, where warming continues to release greenhouse gases into the atmosphere at unprecedented rates.

The international research team, funded by NASA as part of their Arctic-Boreal Vulnerability Experiment (ABoVE), recently published their results in Nature Communications. What they found are bubbling lakes as greenhouse gases are released from the previously frozen ground, leading to increased greenhouse gas emissions and a warming positive feedback.

The Arctic is one of the largest natural reservoirs of organic carbon, trapped within the frozen soils. If a tree dies, say in the Amazon rainforest, it is quickly eaten (rot) away by bacteria, which respire the same as humans. As bacteria eat the tree they inhale oxygen and release carbon dioxide. Hence, the carbon taken up by the tree through photosynthesis is then released back into the atmosphere as carbon dioxide for the cycle to start all over again.
