14. The blue ice over Lake Fryxell (below) is a result of fresh water melting off the Canada Glacier as well as other smaller glaciers. The fresh water freezes on top of the saltwater lake, sealing in the briny water below and creating the crystal blue ice on the surface. (Wikimedia Commons)

15. Adélie penguins’ numbers have decreased significantly due to sea ice loss — a fate that scientists believe may befall Emperor penguins as time goes on. (Vassal Tzvetanov/Flickr)

16. Gentoo and Chinstrap penguins, on the other hand, are ice-tolerant as opposed to ice dependent, which means the areas suitable for their habitats have expanded. (Hamish Moffatt/Flickr)

17. According to Dr. Bert Wouters of the University of Bristol, "The westerly winds flowing around Antarctica have increased in strength in recent decades -- probably as a result of global warming and changes in the ozone hole." (Wikimedia Commons)

18. Dr. Wouters continued, "Now, because these winds have become much stronger, they are pushing more water from the deep ocean on to the continental shelf of Antarctica. This water is relatively warm. It's not warm like in Majorca, for example, but it has a temperature of one to two degrees centigrade, which is above the freezing temperature of ice, so it carries enough heat to melt the glaciers and their ice shelves from below."

19. One study recently reported that the eventual collapse of the West Antarctic ice sheet could lead to a sea level rise of as much as nine feet worldwide. (Christopher Michel/Wikimedia Commons)

20. If this were to happen, a global catastrophe would occur as coastal cities around the world would flood to the point of being uninhabitable. (Pixabay)

21. And if not by sea, by air: Pollutants such as DDT become concentrated in the Polar Regions and work their way up through the food chain over time. (Jerzystrzelecki/Wikimedia Commons)

22. The Rothera Research Center houses scientists all year long, enabling them to observe and document the Antarctic climate through all seasonal changes. (Pixabay)

23. Changing climates may also explain the rise of invasive species in the region. UK-based scientists have shown that an invasive insect species — a kind of midge — could drastically alter the Antarctic landscape in years to come. These insects have contributed large amounts of nutrients into the soil, changing the way in which native species live and evolve. (Pixabay)

24. In an interview with BBC News, Professor Peter Convey with the British Antarctic Survey said: "We could drive locally or generally extinct some of the unique species that already exist in part of the Antarctic." (Pixabay)

25. Though there is some debate as to the rate of the changing climate and landscape of Antarctica, there is no doubt that the effects humans have made on climate change are going to continue – and worsen, if action is not taken. (Christopher Michel/Flickr)
