In the last decade global warming became a huge issue around the world. As scientists discovered greenhouse gases, mainly carbon dioxide, global warming took place explosively due to human activity. The change in temperature seems to raise many new problems and obstacles, some more minor alternatively more important than others.
The most severe one is the melting ice issue occurring right now. It is regarded as very important as it arises many new issues and problems humanity has to deal with. For example, the thawing peat bogs in the sub-Arctic region of Siberia which are starting to melt and will release billions of tonnes of methane that are 20 times more potent than carbon dioxide. They are also issues occurring due to ice melting at the Antarctica. Figures show that between 1996 and 2006 the net loss of ice rose by 75% which can influence the rise in sea levels drastically, the albedo effect which release another positive feedback, and the extinction of animals, such as polar bears. This shows how one consequence can trigger many new ones that cannot be prevented anymore. Consequently, shows the importance of the consequence ice melting which is also pointed out by the assumption that it is a tipping point of global warming.
