Lake Abraham in Alberta Canada has a curious characteristic of frozen bubbles or air pockets within it. These air pockets are created by decomposing organic matter including plants and animals which emit methane gas. Normally the bubbles rise to the surface however in low temperatures they freeze. Due to global warming, scientists believe that the methane content in frozen lakes around the world may be released increasing the rate at which global temperatures rise.
