Have you ever been sitting outside on a hot day and thought, “It could never get hotter”? If the world’s climate keeps getting more extreme this could be a problem as soon as the next year! The mean global land temperature has gotten steadily warmer over the past 100 years and has set record highs since 2014. Just two years ago the average global CO2 levels was at 400 parts per million, the highest recorded in a million years(Weart). Global climate change has increasingly become a part of our society today because of how polarizing the issue is, as many people doubt the scientific evidence that is presented. Many events have affected how the world reacts to climate change but four main events really changed how we view and work to stop global climate change. These events are, The first documentation of climate change by Arrhenius, the birth of earth day, the Earth Summit held in Rio de Janeiro, the Kyoto Treaty, the failure of the Copenhagen Treaty, and the creation and signing of the Paris Climate Accord.The only way to truly understand why the global temperature has gotten more diverse is to take a step back in time and find out why we are having this growing problem. Way back in 1896, about 50 years after the end of the industrial revolution, Swedish Scientist Svante Arrhenius first documented global warming from CO2 emissions. He suggested that the Earth was not in some “periodical warming” but human affected warming(Weart). This was a very big change in the way people viewed Earth’s cycles because up until then the vast majority of the public believed that humans were too puny to change the mighty Earth’s climate by themselves(Weart). Arrhenius put the idea on many people’s mind that the earth’s climate is much easier to affect then the majority thought. In 1970, an important holiday was founded, Earth Day. Gaylord Nelson, a Democrat Senator from Wisconsin, was the person to promote the day and is now credited to have created it. He was so successful the first year that over 20 million people took part in marches, speeches, and rallies(Earth Day Network). Earth day was such a massive hit that a United Nations subcommittee, the US Environmental Protection Agency, was formed to help the environment and keep it healthy. Nelson is known to have said, “The ultimate test of man’s conscience may be his willingness to sacrifice something today for future generations whose words of thanks will not be heard”(Earth Day Network). This really shows he is such a great man that he will sacrifice years of his life planning and organizing for gratitude from people he will never meet. After about 20 years of increased effort to slow the effects of climate change down a conference was planned for the summer of 1992. This conference was the “Earth Summit” held in Rio de Janeiro, Brazil.When the Department of Public Information did research on this they said, “This conference hosted 172 countries of the world and every single person in the conference room was eager for a deal to help out our environment.” After 11 days of hard work in the heat of the Brazilian summer the attending countries had a couple of ideas to stop the problem. The first idea was to use campaigns to get the general public to increase the use of public transportation. The second and most influential idea was to slow and eventually stop the use of fossil fuels for energy(DOPI). Cleaner and more sustainable methods were stressed and many countries attending did significantly cut the use of fossil fuels. The Earth Summit was very successful and was a key stepping stone for many conferences to come from. One major conference that came soon after the success of the Earth Summit was the Kyoto Protocol. This meeting of 182 states was focussed on stopping the use of 4 harmful gases to our environment, CH4, CO2, N2O, and SF6 (Schenker). These gases are put in 2 major groups, Hydrofluorocarbons, usually named HFCs, and perfluorocarbons, usually named PFCs. These gases are used instead of Chlorofluorocarbons abbreviated to CFCs and Hydrochlorofluorocarbons more commonly called HCFCs. HFCs and PFCs do not deplete the ozone layer like their counterpart CFC gases but they are still very dangerous greenhouse gases in our atmosphere. The Kyoto Protocol also aimed to lower greenhouse gas emissions by 5.2 percent of 1990 levels not including air travel or shipping(Schenker). This goal is very achievable because commercial travel accounts for about 27% of our 2015 greenhouse gas emissions (NASA). Many manufacturing companies label these gases as environmentally safe because they do not deplete ozone but they are actually some of the most potent gases in our atmosphere. This is why the “F” gases are believed to be safer than they are. The Kyoto Protocol really hampered down on this belief and put it to rest once and for all(Schenker). Nowadays people know the dangerous effects of these gases and we have the Kyoto Protocol to thank for that. 119 years after the groundbreaking discovery of Carbon Dioxide global warming a Conference was planned for December of 2015 in Paris France. This conference is the Paris Climate Agreement, PCA, the widely successful and controversial agreement by 194 countries. The goal of the PCA is to stop the global temperature from rising over 2 degrees celsius, 3.6 degrees fahrenheit, above pre-warming levels (Jazeera). This agreement is also aiming to reduce carbon emissions by 40-70% by 2050 and fully eliminate the emissions by 2100. These goals are very ambitious long term but do not make much of difference for the next 30 years. This is why the only country currently not signed onto the agreement, the United States, is trying to leave the PCA. Donald Trump, who pulled the US out, is being criticised by many world leaders for leaving. He believes the PCA is not doing enough and must be reworked soon(Jazeera). Many cities in the US are taking pledges to follow the guidelines the the agreement even if they are not bound to. The United States was able to request to leave the PCA before the length of time needed to leave because there is no incentives or punishments for countries who follow the rules or break them. The United States past president, Barack Obama, said, “It is the best chance we have to save the only planet we’ve got”. Obama was a main skeptic of Trump leaving the accord because he was a core developer of the accord. It is believed that Trump left the accord because he wanted his own climate accord, he thought that the current accord was not strong enough, and he did not think the United States, the world’s second leading CO2 producer only behind China, could achieve these standards (Jazeera). To be able to slow and eventually stop global warming everyone must show their local, state, and even national government what this means to the people of our country. Some top level politicians still strongly deny global warming and therefore do not do anything about it. There are some concrete facts that global warming exists, even 97% of scientists say so. Sea levels are rising and no one can deny that, one must lower their barriers to auto-deny everything and look at the basics. The ocean levels rising simply are not tides. Tides do not last forever, the ocean levels will not go back down without hard work from all of the people in the world. For the world to truly heal from this catastrophic event governments globally must allow tax cuts for clean energy users so many more people will stop supporting the top carbon emitters, power plants(NASA). Governments must also pay the extra money to make sustainable energy sources like hydroelectric power plants, solar panels, and much more. This solution would not only deal a major blow to carbon emitters but it would make a foundation for the world to build off in the future. Global Climate Change has taken many dramatic turns throughout the years including, The first documentation of climate change by Arrhenius, the birth of earth day, the Earth Summit held in Rio de Janeiro, the Kyoto Treaty, the failure of the Copenhagen Treaty, and the creation and signing of the Paris Climate Accord. One must hope that the effects of these changes help make the world a cleaner, healthier, and better place.
