__**Relation to climate change**__ Earth is called the blue planet because the Atlantic, Pacific, Arctic, Indian, and Southern Oceans cover about 71% of the the earth. Out of the 1.34 billion km3 of water that the earth has, about 97% of that water is saltwater. People think of our earth as a heat sink because it absorbs the heat then stores some of it and finally releases large amounts of it. The ocean buffers the climate of nearby land and eventually the entire planet.

Over time heat levels have began to rise more and more each and every year. Every year the oceans struggle more and more to absorb oxygen. The oceans get more barren and lifeless every single year.
 * __History of the Issue__**

__**Explanation of the Topic**__ The surface temperature of the earth has increased from 0.45 - 0.6 degrees celsius in the past century. Computer climate models beleive that the earths surface temperature will rise significantly in the next century, as well as a rise in sea level too. An explanation for these beliefs are the emissions of greenhouse gases which shield and trap the heat inside earths atmosphere.
