Permafrost refers to layers of soil that often remain frozen throughout the entire year. Warmer summer temperatures have increased the thawing of permafrost in Alaska. As the permafrost thaws, organic matter begins to decompose. This decomposition contributes to global warming because the thawed permafrost decreases the photosynthesis on the surface. permafrost absorbs greenhouse gases when it is frozen. the decomposition of organic matter releases water vapor into the atmosphere. the decomposition of organic matter can emit carbon dioxide and methane into the atmosphere. the thawing of the permafrost decreases the albedo of the landscape.
