A prime example of this is the Arctic biome, which is made up of low lying vegetation. Although not categorised by climate, it is intrinsically linked with the distribution of the world’s major biomes, as it is the underlying cause of what types of vegetation are able to inhabit…

(2013) discuss this further, stating “the sea-ice biome influences the abundance, distribution, seasonality, and interactions of marine and terrestrial species.” This is especially true for polar bear populations in the Arctic, as…

    Predicted arctic warming is the most ominous force. Arctic warming is associated with rising air temperature and warming sea currents. These, in turn, are associated with human activity releasing Co2 and other gases that trap more solar energy in the earth’s atmosphere. If nations could agree to cut the emissions of gases drastically to preindustrial level, warming might reverse. Some of the last and largest unexploited oil fields in US territory alone now lie near and under arctic oceans. As…
