Answer: The release of methane from thawed permafrost
Explanation:
With increasing global warming, permafrost in the arctic is melting. The carbon and methyl clathrates present in permafrost escape into the atmosphere to form carbon dioxide and methane, both greenhouse gases.
In the Arctic, molecules of methane are trapped in ice crystals as methyl clathrates. When the temperature increases, these crystals release methyl clathrates which become methane when in contact with the atmosphere.
The cause of the increasing atmospheric 
is due to the the thawing of dead organisms present in the permafrost. As the permafrost melts, these organisms decay and release into the atmosphere.
Hi!
The association is enforcing the Riparian Water Rights.
The Riparian Water Rights allows the landowners to make reasonable use of a body of water which flows through their properties. These reasonable uses include fishing. If the water is non-navigable, the owners have the right of exclusive use of the body of water.
When an association in a town shares a lake, and only the association's members are allowed to use the lake for fishing, the association is enforcing the Riparian Water Rights.
