Permafrost.

The increase in global surface temperatures have lead to the melting of permafrost predominantly in the northern hemisphere, intensifying the release of greenhouse gases into the atmosphere.  As permafrost is directly related to the carbon, methane, and nitrogen cycles I thought that it would be important to include a brief video on it, especially as its melting is rapidly changing the roles and efficiency of microorganisms native to these “permanently-frozen” environments.  In the video scientists summarize the environmental factors leading to the melting of permafrost, the role of microbes in releasing stored greenhouse gases, and future environmental and health-related concerns if it’s melting is not stopped.
