Global Warming : We Must Fully Understand The Way It Affects Us

Global warming -- and climate change -- have long-term and short-term impacts on our environment. Caused by air pollutants such as carbon dioxide and methane, global warming is the gradual increase of air temperature across the globe. The rise in air temperatures can lead to higher extinction rates, increased risk of disease and political repercussions, such as wars over available resources. Understanding the possible short-term and long-term effects can help humans better prepare for the consequences of global warming.

I believe that Global warming is in fact true and that the evidence that we see in regards to the temperature change and environmental change does defend my perspective. Studies have shown that global surface temperature has increased about 0.74°C within the last century. The global surface temperature is also expected to increase by another 3–5°C in 100 years to come (5). Even though this relatively small number may seem insignificant to many people, it has caused many changes to the overall atmosphere that can be further discussed. Changes that are associated with the atmosphere and also the climate change have an influence on the biosphere and human environment (1). The warming of earths

We might disagree on the causes of global warming; however, we cannot ignore that it is happening. Although we still experience cold winters, average global temperatures has risen drastically for the past three decades. Polar ice caps are melting; as a result, sea levels are rising. Scientist predict more extreme weather in the coming decades, in fact, droughts will probably be more common. Also, flooding and tropical temperatures might cause large amounts of methane gases to be released, which could be disastrous for our atmosphere. Climate change may have human causes and also it might be a natural occurrence. Nevertheless, we must find ways to save our planet.

The increased temperatures are part of a natural cycle that the earth goes through. These cycles include both warming and cooling periods. The most recent warming period was approximately 1000 years ago known as the “Medieval Climate Optimum” (Robinson, Robinson, & Soon, 2008). During the Medieval Climate Optimum the average temperature was much warmer than what is now. 1000 years ago they didn’t burn hydrocarbons like we do now, and the temperatures then were warmer than they are now. 200 - 500 years ago the earth went through a cooling period known as a “Little Ice Age” (Robinson, Robinson, & Soon, 2008). We are currently recovering from that cooling period. During the Little Ice Age temperatures dropped well below average. However, a study of more recent history temperatures can also show that the climates are cyclic and not the result of human activities.

Global climate change is more than just raising the concentration of GHG’s in the atmosphere, it’s a serious health threat. Dr. Howard Koh, of the Harvard T.H Chan School of Public Health, has stated that global warming is a threat to human health because of an increase in respiratory and allergy aggravation,

Global warming is defined as the recent increase in the world 's temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere. There are many different theories on whether global warming is similar or not to climate change. Simplistically, climate change is different because climate change is defined as a change in global or regional climate patterns or, in particular, a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels, having been measured over long periods of time, due to the changes in Earth’s orbit and organic carbon which reflect sunlight. Global warming and climate change are not to be confused because global warming is caused mainly by anthropogenic factors like the emission of carbon dioxide gas and use of fossil fuels whereas climate change is completely natural, however, according to Milan Radovanovic, “it is clear that the anthropogenic factors dominate the increasing temperature and the natural ones have the maximum influence…” (Radovanovic). Therefore, “the contribution to global warming from natural forcings and from natural internal variability is in the range between -0.2 to 0.2 [degrees] celsius over the period 1951-2010…” (Radovanovic). Natural factors have had the most effect on global temperature in the past 59 years totaling a 0.4 degrees celsius increase in

Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.

Global warming is a phenomenon that has amazed and frightened everyone ever since it came into being. The consequences and end results of global warming is what goes on to alarm and frighten everyone on earth. If looked at it literally, global warming is basically in increase in the temperature of the Earth's atmosphere. This change and elevation has been occurring ever since the 19th century and is known to increase even more. The change in the global temperature is dangerous because it goes onto increase the sea levels and alterations precipitation, melting of glacier and possible risks of floods around the world. Global warming can even cause a spread of the deserts (Lu, Vecchi and Reichler 6)

In the past 130 years, the average temperature increased by 1.5 degrees Fahrenheit, with more than half of its increased in the past 35 years.( Science for a healthy planet and safe world). In 2001 to 2010 it was the warmest decade since 1880. However this was the year when enough temperature records became able to calculate a global average. However it shows that average global temperature are likely to increase by 3.1 to 7.2 degrees Fahrenheit by end of the century depending on how much carbon is released.( Climate hot map). In the past 40 years it has been the warmer than average. The hottest year recorded. The other 12 hottest years recorded have all occurred since1998. ( Science for a healthy planet and safe world).

Global warming has been a conversation holder for the past decade or so. Years ago people believed that global warming was a myth, and was not going to happen. Now for the third year in a row temperatures are becoming warmer and warmer. Scientists are becoming more alert to the steady pace of earth's temperatures rising. In the article “Earth Sets a Temperature Record for the Third Straight Year” by Justin Gillis, he explains that earth is casually becoming warmer every single year. After reading Gillis’s article I would strongly agree with him, I believe his article gives concrete evidence that earth is warming up, and could potentially cause many problems. Global warming is happening and will eventually cause extinction, rise in sea level, and effects on weather.

Over the last 100 years, global temperatures have warmed by approximately 1.33 degrees Fahrenheit, and more than half of the rising temperatures have happened since 1976 (Pappas). The Artic has warmed twice as much as the planet as a whole. The average surface temperature in the Arctic from January till September of 2016 was by far the highest we've observed since 1900 (Grenoble). There were record temperature highs set in January, February, October, and

Last but not least, global warming has caused the polar ice caps to melt. The melting of the polar ice caps will cause the sea levels to rise all over the world. If the sea levels rise just a metre

global warming is causing many conflicts around the world. Conflicts like melting ice glaciers, which causes rising sea levels. If the sea levels rises it can cause floods all around the world. If the sea levels keep rising some island will disappear. Heat waves are getting more and more common and will cause droughts. Cloud forest like true ecological kings of the jungle are dying off rapidly because of roads are being built, and farm settlement. The ecosystem is shifting in many parts of the globe, growing seasons is 2 weeks longer, animals are endangered, hibernation and migration is getting affected because of All of these has increased rapidly over the years.

Global warming has a lot of causes and effects throughout the globe, including: icecaps melting, deforestation, carbon emissions, factory smoke, forest fires, coral reefs dying, and extreme weather catastrophes. All of these causes and effects listed can be prevented if only the population of people who do not believe it is real would start caring about the environment and what we release into the atmosphere.

Global warming is a huge concern in society that is only growing bigger because people either are not well informed about it, or they are not concerned about it. Some think that it will just go away and others still believe that it doesn’t exist, even though there is hundreds if not thousands of pieces of evidence that supports otherwise. One of the biggest pieces of evidence that proves global warming is real is the effect that photosynthesis has on global warming.
