Documentary: The Impact Of Global Warming

Improved Essays
In the documentary “The Impact of Global Warming” it showed many ways of how global warming can effect and is effect our society and our planet. One of the impacts of global warming that the documentary addressed was the rise in sea level. There are many causes that effect the rise in sea level but one specific effect is the melting of glaciers and ice caps. When our temperature increases dramatically high it causes many of the glaciers that are situated across the globe to melt, whether its little or a lot, it does have effect on the sea level. For example, many people in the Himalayas are dependent on meltwater rivers which supply their drinking water, if the sea level rises it will contaminate their water supply. Another effect of the rise in sea level …show more content…
One of the causes in the decrease in salmon catching is due to the rise in sea temperature. In the Film it stated that in the 90s the sea temperature was much warmer than it is today. This could mean that since the water temperature is too cold for the salmon they migrate some where else where it is warmer. Another cause of the decrease in Salmon, is that not a lot of salmon are making the journey back from the ocean to fresh waters where they lay their eggs, which causes less reproduction of salmon.
One other impact of global warming that the film addressed was the problem of spruce beetles. Spruce beetles usually live in the south where there is always a high temperature. In the film it showed in recent years the beetles have been migrating to the North, which is unexpected because the North is the coldest, but with recent climate change and the increase in temperature spruce beetles can be found in Alaska. The migration of spruce beetle not only shows the drastic change in temperature but it also causes problems, in the documentary it stated that the spruce beetles in some areas have destroyed 90% of

    The environment throughout the planet has been changing drastically. In his book An Inconvenient Truth, Al Gore wrote that Antarctica and The Arctic are affected the most because they are on the top and the bottom of the Earth. The Arctic ice cap keeps the earth cool. The planet is at an increased temperature which has caused the ice cap to thin and melt at a rapid rate. As Al Gore later states, when sun hits the ice it usually reflects it like a giant mirror but with global warming the sun shines on open water causing the ice cap to melt.…

    The IPCC, said in its 2013 report that “even modest warming may drive large increases in transmission of malaria, if conditions are otherwise suitable.” Sea level are also rising due to glaciers melting. The increasing CO2 emissions from fossil fuel combustion have led to an exponential increase in the net amount of CO2 being dissolved in the ocean. Dissolved CO2 creates carbonic acid, which reduces the ocean pH level, making it more acidic. This is bad as it would very likely have a major impact on the ocean life. If the CO2 concentration continues to rise and the pH level continues to fall at current rates, the ocean pH could drop by as much as 0.5 during the 22nd…

    At this rate the next generation will have little to no glaciers to see. Due to this ice melting it causes the ocean levels to rise. Over time this can have an impact on humans being displaced from the flooding of coastal areas. “A recent study found that if average temperatures rise by three degrees Celsius, Greenland’s enormous ice sheet will begin to melt and sea levels all over the world may rise by a half foot to three feet or more” (Simon 18). The ocean itself is also warming.…

    Human activity has a great impact on global warming. Events, such as burning fossil fuels, contributes much of the carbon dioxide that is emitted into the atmosphere. Global warming effects caused by human activity affects the earth 's climate in many ways. It is melting the earth 's poles, glaciers and ice sheets which causes sea levels to rise. It is also shifting climates and precipitation patterns and is forcing animals to migrate.…

    Melting permafrost plays a large role in the melting of the ice caps. The melted permafrost causes the ground to become soft and causes the ice above to melt and fall into the ocean. The increase in global temperature causes chunks of ice from the caps melt and fall into the ocean causing a rise in sea levels affecting buildings and…

    Also, the sea levels will rise due to ice melting and people who live near the shores all across the world will slowing watch the water creeping up the shore. According to Quirin Schiermeier, a writer for Nature, an International weekly journal of science, “Scientists have come up with the firmest evidence so far that global warming will significantly increase the intensity of the most extreme storms worldwide” (Hurricanes are getting fiercer). In other words, global warming is causing the wind directions to shift, resulting in extreme storms. With all these effects, the devastation of global warming seems inevitable. However, there is a solution to slowing down climate change and eventually fixing it.…

    According to scientists, the rise of sea levels is as a result of the melting of ice sheets due to global warming. This therefore means people near water bodies will be displaced to escape death. More storms are also experienced as a result of global warming. These storms are of great intensity and therefore become a big threat to people as they can result to deaths. The rise of temperature could also lead to extermination of many species and since most of these species of importance to human beings, it therefore results that they too are in great danger.…

    We can also observe melting ice caps in areas such as Antarctica and the Artic Circle. Ice caps such as these contain enormous amounts of water, and have the potential to raise sea levels by several feet. Coastal cities across the globe would be forced to alter communities and building developments due to the rising sea level; therefore, millions of people would be affected. In addition to increased sea levels, riverbanks could rise as well, expanding the potential for floods. The warming of the Earth would also increase the rate of evaporation, affecting the amount of freshwater readily available.…

    Basically climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change is the greatest threat to nature and humanity in the 21st century and it is happening everywhere. Even today, in many parts of the globe we can see some effects of climate change - melting glaciers, rising sea levels, severe storms, heavy floods, reduced snowfall in the north and a severe drought in the south. Even though the Earth's climate had been fluctuated before in the last 100 years it happens much more often. The average surface temperature has increased by about 0,6-0,7 C. It may seem that it's not too much, but since the climate has become "nonlinear" dynamic system, even small…

    Also, a number of glaciers have been located by the scientists. Hence, as a result, the cities and the coastal parts may be soon submerged under the sea vanishing many islands along with the rise in the level of the sea. Global warming changes the climate and the change in climate will make extreme hurricanes. Significantly, strong hurricanes have been formed from last few years giving us an example. Comparatively, the unusual warming of the world will face water crisis in many parts whereas other parts may be wetter.…
