Global Warming Controversy

Humans have known about global warming for many years now. But Al Gore did not discover global warming. Neither did Tim Flannery, Peter Garrett, Greenpeace or Malcolm Turnbull. However they did add their scientific two cents and made everyone more knowledgeable on what this topic is really about, and stressed the importance it has on the Earth. Scientific concern about global warming is not new. This is nothing surprising or new to the world. Although new studies about this topic is brought up often. Many amount of people believe that our concern about global warming is a modern day obsession which is driven by the attention of high-profile personalities, politicians and green activists. Also that we shouldn’t pay so much attention to it, and give our attention to “bigger problems” that’s going on in the world. Global Warming is a controversial issue we have faced for many years, there is many reasons why people believe and disbelieve that Global Warming is a real life issue.

There is no exact date you can put on the discovery of Global Warming, neither person to say they discovered it as well. Many people had their own theories, and added on to each others beliefs before everything was summed up to what now is Global Warming. However, these studies goes way back to the late 1800s, when scientist started to notice the change of temperature. The first person to look into climate change was Svante Arrhenius. Arrhenius was a Swedish scientist, also the first person to claim fossil fuel turmoil will eventually result to what now known as Global Warming/ Climate Change. “He found that the average surface temperature of the earth is about 15oC because of the infrared absorption capacity of water vapor and carbon dioxide”(Enzler). That is called greenhouse effect, which is one of the main causes of Global Warming. Arrhenius also believed that human activity can also add to climate change by putting carbon dioxide into the air and warming the earth. He was not researching about climate change for no reason, this was part of his own research to figure out if global warming was the cause of the great ice ages. Which was found out to be true in 1987, and after Arrhenius discoveries the topic was forgotten for quite some time. However most people believe that Global Warming was discovered by an American scientist by the name of Wallace Smith Broecker. He was a scientist at Columbia’s Lamont-Doherty Earth Observatory as well as a Professor at the Department of Earth and Environmental Sciences at Columbia University. Broecker was also a writer and published a total of 10 books and wrote more than 450 journal articles.On August 8th, 1975, he published a paper in the Science magazine. The paper was titled “Are we on the brink of a pronounced global warming?”, where he first used the term “global warming”. Which is why he is believed to be the first person to discover it. Before his article was published the term “global warming” was mostly known as “inadvertent climate modification” by other scientists. However, Broecker believed that the term, “modification” was innocent. Because the term modification meant the temperature could go either way (warmer or colder). Broecker proved that to be wrong, and that it would only get warmer because of the ozone layer thinning, the earth would be more exposed to the sun. One major source of believers are the vast majority of the scientific community. Which debate with others on whether or not Global warming is caused by human activity or from natural sources, for example volcanoes and forest fires.Those believers of Global Warming believes Global Warming exists because of something called the greenhouse effect. This controversy has been going on for many years, although gained a lot of attention in 2005. When former Vice President Al Gore created his documentary called “An Inconvenient...
