Global Warming: Crisis or not? Intro to global warming topic – facts/introduce both sides (humans are cause, humans are not cause)
Earth’s history is filled with drastic climate changes, from ice ages to warm fertile periods. But only in recent years has the thought of humans having an impact on Earth’s climate been an issue. The definition of climate change is “the long term change in the statistical distribution of weather patterns over decades to millions of years,” but some recent definitions of climate change have been formed with the idea of human impact embedded in them. One such definition states “climate change as mainly the change in modern climate augmented by human activities.” Ideas of this arose in 1896 when Swedish scientist Svante Arrhenius carried out the first calculations of global warming. Arrhenius lived during the time of the industrial revolution, which introduced the use of coal, railroads and factories. He had ideas that the CO2 produced from burning fossil fuels might contribute to the increase in temperature of the Earth. Global warming is a global topic and the source of much controversy in the world today. Although some people may be skeptical of it, global warming is real, and there is evidence to prove it. On a basic level, we have noticed that the average global temperature has been rising over the past one hundred and thirty years, with the majority of this warming occurring since the 70’s and the warmest years within the past ten years.
