Polar regions

The arctic and Antarctic are known to be the coldest and darkest places on this earth.  The Antarctic is a land mass surrounded by ocean wearers  the arctic is a group of different country's.

They are located in the north and south poles and are associated with high latitudes. The polar regions are harsh and desolate but support an important ecosystem. In these regions the sun is less direct and the energy is spread over a larger area, this is the main reason why they are cold. Another reason is because these regions are usually covered with snow and ice that reflect sunlight causing not heat to be absorbed into the earth.

The environment of these regions have changed dramatically over the last 50 years due to human activity in these places.  The growth of: commercial fishing an hunting , mineral exploration, scientific bases and tourism. Human activity is in increasing earths temperature causing ice to melt making it even more hot.

Cold climate- During the last great Ice Age, about 18,000 years ago, the Earth’s climate was radically different from that of today. The difference was larger even than is sometimes projected for future climate states under doubled CO2. Studies of bubbles in polar ice cores have shown that Ice Age atmospheric CO2 was much lower than recent pre-industrial levels, which supports a link between CO2 and climate.
