Climate change is not an unnatural event for the floating planet. According to scientists, over millions of years the Earth has experienced numerous periods in which the climate oscillates between extremes of heat and cold. For example, during a period called the Paleocene-Eocene Thermal Maximum, Earth's average temperature increased by 11ºF. Since the end of the 18th century, just after the Industrial Revolution, the Earth's average temperature has increased exponentially. While few would argue that this change is ordinary, available data and painstaking observations show that human activities that release greenhouse gases may be related to ongoing climate change. Because change poses a dangerous threat to the world, many countries, across all continents, have made efforts to mitigate it. Latin American countries and China are just some of the countries involved in this movement. The improper use of natural resources, one of the main causes of climate change, causes a serious economic crisis. To prevent such an event, the effective use of raw materials should be the top priority of all countries. More and more people are more familiar with the term “global warming” rather than “climate change”. However, scientists prefer “climate change” because the term gives the public a fuller sense of what is happening. The Earth is not simply warming. Due to the excessive quantity of carbon dioxide, other phenomena also occur. For example, as the concentration of carbon dioxide increases, the acidity of the ocean also increases. When the pH changes in ocean water, the organisms living within it will be affected because they are not accustomed to the new, rapidly changing environment.
