The Arctic Ocean is defined as the waters surrounding the North Pole, located within the Arctic Circle, including the northernmost islands of Canada, Norway, and Russia and is mostly covered by ice sheets, ice floes, icebergs and sea ice. Sea Ice is a thin, fragile layer of frozen ocean water that forms in the Arctic and Antarctic oceans. On average sea ice covers 20-25 km² of the Earth, accounting for 7% of the sea surface. The maximum extent of Sea Ice in the Arctic is recorded as 13-15x 10⁶km²
surface is covered with water while the rest of it is covered by land. Meanwhile 97% water supply of Earth is oceans. Oceans are vast water bodies having salty water. There are Pacific, Atlantic, Indian, Arctic and Antarctic oceans. This saline body water houses various animals and plants. Humans can draw many benefits from oceans. For instance the lands near oceans are normally cooler and the oceans may be responsible for the change in weather. In simple terms they act as heaters in the winter season and

Research shows that a recent and rapid drop in surface pH that could have shocking global consequences through the distortion of the ocean’s acidity. Since the
She was visiting this region to observe global warming and the effects it was having on the immediate environment. The effects of climate change are being felt in every corner of the globe, especially in the Arctic. Currently, because of climate change, the permafrost is melting, glaciers disappearing and sea ice receding. Attwood even talks about the disappearance of the permafrost, “The northern permafrost melted and the vast tundra bubbled with methane.”
world are rising at an increasing rate – considering how devastating the effects of the last mass extinction as a result of climate change were, it is not very difficult to predict the end this time around. Alternating precipitation patterns, changing ocean currents, melting icecaps, floods, droughts, tsunamis… every year we see more and more occurrences of each of these disasters, and still manage to refuse to acknowledge one of the biggest and scariest one of our problems as a significant threat. This
the beauty of the ocean. Now, imagine walking on the same beach but the ocean is almost gone, and the rest that is left is completely contaminated such that one can notice the dead animals in the sand. All the different kinds of marine animals are now extinct and it is all the fault of human society. The Planet Earth is the only planet in the solar system that is able to sustain water. 71 percentage of the entire planet is covered by five oceans which form one complete big ocean. In other words, these
The impacts of marine pollution are vast and prominent in our planets oceans. Our Earth is a delicate ecosystem, which has been put into extreme stress due to human activities. This includes everything from the more radical- oil spills, waste and industrial dumping- to the minor scale human activities such as garbage and household disposal that become waste runoff into the sea. However, Williams (1996) notes that even though there are both radical and minor cases of pollution, we should view them

Throughout history, many conflicts and clashes have occurred over the location of certain parts of land. “From pole to pole the Union Jack whipped in Arctic gales or sagged in the tropical heat of this empire upon which the sun never set. ...
