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.
Answer:
northern
Explanation:
<u>Northern Hemisphere is the name to the top part of the Equator, one that goes on the north from it. </u>Earth is divided by the imaginary lined in the middle, and that line is called the Equator. The Northern Hemisphere includes the whole of North America and Europe, the bigger part of Asia, and some parts of Africa and South America.
