Climate you think that it’s something catastrophic.

Climate change is a process that is always taking place on this earth, but the reason that it is such a big deal now is because it is happening at a much faster pace than what is considered normal (Randazza, 2017). Global warming can have its benefits depending on the way people see it, but they are usually short term. For example when you think of global warming causing arctic ices to melt, you think that it’s something catastrophic. Others may see it as a way for ships to avoid icebergs, and resultingly make it easier for ships to navigate without being scared that the ship will sink. Another benefit that some people may see is the increase of agricultural land that used to be covered by ice. Nonetheless, these ‘positives’ will turn into negatives in due time. As of now, global warming is negatively affecting many different aspects of the Earth. These include the increase of the average global temperature and ocean water, the shrinking of ice sheets, the decrease of glaciers and snow, the rise of sea levels, and ocean acidification. The first and most crucial proof of climate change is the increasing global temperature. The average temperature of the Earth has risen 2 degrees F since the late 1900s. In 1950, the average global temperature was approximately 57.4 degrees F. Now that number has risen to almost 60 degrees F.  This just shows the effect of carbon dioxide in the atmosphere, as shown in Figure 1. From 2001 to the present day, each year is the warmest year ever recorded in history. And 2016 showcased the warmest temperatures ever recorded for 67% of the months. The increase of the temperature of the ocean is also very crucial because it risks almost 70%, the percentage of water on the globe, of our earth. The pollutants that cause the atmosphere to thin also have a huge effect on the ocean. As said earlier, they contribute to the increase of the evaporation of  water. Evaporation is directly related to heat, and thence the temperature of the ocean increases substantially.  The ocean’s temperature has increased especially around the equator, where around 700 meters of the ocean’s temperature increased 0.3 degrees F. This global warming also plays a huge role in the melting of many arctic ice shelves. It also helps intensify the amount of rain and extremity of hurricanes. These increases are not a part of the natural progression of the planet, but are something extraordinary that may haunt the future generations. A huge part of what makes the earth exciting is its vast variety of different landforms in different areas. These include ice sheets, which cover 10% of the Earth, including areas in Greenland and Antarctica, but sadly they are receding due to the increase of global temperature. Greenland has lost 36-60 cubic miles of ice each year from 2002-2006 (NSIDC, 2013). This number has increased every year and still does now. Antarctica has lost around 36 cubic miles of ice combined from 2002-2005. In 2000, there was around 6.5 million square miles of ice in Antarctica. In 2012, that number dramatically dropped to around 6.2 million square miles. A 5% decrease in the mass of the ice sheets! At this rate, these ice sheets could be completely gone in less than 30 years. Glaciers are also decreasing in almost every part of the world. Around 400 billion tons of glaciers melted each year since 1994. Antarctica lost 118 billion tons while Greenland lost around 281 billion tons of ice.  If there is any hope of changing this, it has to happen now, or else it will be too late to further preserve the ice of our Earth.The sea level has also risen due to global warming (Sea Level, 2017). This is due to two important reasons: (1) the vast amount of extra water due to the melting of glaciers and ice, and (2) the expansion of waters due to temperature increase. From 1993 to present, the ocean has risen 3.4 millimeters a year, and has increased to 200 millimeters from 1870. The oceans have not just increased in temperature, but they have also been exposed to more carbon dioxide. This resultingly causes the ocean to become extremely acidic. And since the oceans absorbs 33% of the carbon dioxide from human made machines, the acidity in the ocean has increased to 30% since the Industrial Revolution. The ocean absorbs around two billion tons of carbon dioxide per year since the start of this decade. Overall, climate change has caused a lot of problems for the oceans.
