With every other year, it gets more difficult to deny climate change. The ice cap is melting, the sea level rises, the average temperatures grow. The impact of climate change on ecosystems may soon be dramatic. Today we observe major changes in ecosystems triggered by warming. Some species become extinct, others migrate without any optimistic prospect. Living beings strongly depend on a stable environment. Even humans rely on favorable climate conditions more than we think.
Melting of icy lands and glaciers is vivid. It causes the rise of sea level, which brings floods to coastal areas. Nevertheless, Greenland and other countries in the Arctic Circle seem to benefit from warming. As the ice melts, Greenlanders unlock their frozen reserves such as farming, mining, shipping, and tourism. An ice-free Northwest Passage between the Pacific and Atlantic Oceans provides a better sea access to Canada. However, the benefits of ice melting are questionable. Greenland currently suffers from droughts, and ice-free areas in the North make an easy way to the drilling of the sea shelf.
Many species became extinct in the climate change. Coral reefs are the most vulnerable to warming. The Caribbean region has lost half of its corals since 2005. Lately, Japan’s government announced that most of its large coral reef system has died. The Australian Great Barrier Reef has also suffered. The US National Oceanic and Atmospheric Administration predicts that coral reefs would vanish almost completely by 2050.
