Climate change

Global climate has a long history of cooling and heating. However, this time is different because people are causing it. Climate change is a significant weather change in many places, which means the normal weather of most spots in the world is changing. Scientists have developed many ways in order to measure climate and be able to accurately predict the changes in the weather. They measure the percentage of the rainfall over the last years, the temperature all over the world, and the speed of the wind. Scientists have also observed that climate change has been occurring more rapidly during the last century. It is believed that the main causes of climate change are results of human inventions. For example, the emission of greenhouse gases cause holes in the ozone layer, which results in changing the weather in many places. Climate change effects Earth due to these reasons: the rise in the sea levels, the extreme weather, and the loss of bio diversity.
One of the results of the change of the weather is sea level rise. Because the weather is warming in many places, the polar ice cap is melting. To illustrate, during the past century, the level of the sea rose in an average of seven inches (Climate, 2014), while it remained the same for the prior two thousand years. Therefore, if the rising percentage continues, many cities around the world could face a tremendous threat of sinking in the next ninety years. An example for these cities is Boston, Miami, and New York (Climate, 2014). If that happens, many of that cities’ residents will lose their homes, many valuable sites will become history, also that will cause a huge economy failure. All in all, rising sea levels are serious problem as a result of climate change that will cause a complete destruction of some costal cities.
Another main effect is extreme weather. Weather has changed in many areas over the past years. In some areas it is becoming cooler, whereas in other areas it is becoming warmer. The World Meteorological Organization states that the years between 2000-2010 are considered the hottest decade on record (Climate, 2014). That has resulted in increased flooding due to an increase in rain intensity during the last fifty years. Moreover, drought has been increasing as well, especially in some areas around Africa and Asia (Climate, 2014). Since the 1970’s, the percentage of drought has doubled, which results in gaining more desert and shortage of water (Climate, 2014). Also, hurricanes are gaining more intensity. Scientists believe that hurricanes gain more intensity as the ocean becomes warmer (Climate, 2014). To sum up, extreme weather is formed in many earth- threatening forms: increase in flooding, drought, and hurricanes.
Biodiversity loss is also a main effect of climate change. Earth has witnessed a loss of many biological species over the last century (Climate, 2014). In addition, there are many species facing a significant risk of extinction. Moreover, a big number of animals are becoming endangered because of the weather. For example, polar bears are facing a huge risk of extinction because they live with ice, and as the ice melts, the mortality of polar bears raises (climate change impacts, 2014). Plants are also facing the risk of extinction. As the percentage of the desert increases, the percentage of plants in that area will decrease. Furthermore, with all these effects, humans could also face death resulting from shortage of food and drowned cities. All in all, as a result of climate change, Earth will likely to witness a significant biodiversity loss.
To conclude, climate change is a tremendous threat to Earth. Climate Change happened for many reasons, such as the emission of greenhouse gases. However, it has resulted in many aspects, which are the rising levels of the sea, the weather is obtaining more intensity, and a loss of biodiversity. People should work to stop earth from being destroyed and losing its nature so the future generation can live a normal life.
