How Does Global Climate Change?

Superior Essays
The Earth’s climate is constantly changing. These changes result primarily because of the natural process where the Earth’s spheres interact with one another, however human activities are having a greater impact on global warming. There is evidence that human beings are changing Earth’s climate unnaturally. Ninety-Seven percent of scientist have agreed that global climate has undergone an irregular occurrence and changed drastically over the last 100 years so it can no longer be claimed as unimportant. The question now acknowledged by most scientist is how much human activities have affected our global climate and what can be done to save our planet or reverse its warming. Along with that question how much has our climate changed naturally …show more content…
CFCs are a class of compounds of carbon, hydrogen, chlorine, and fluorine. They are harmful to the ozone layer and exposes the Earth to ultraviolet radiation. 2010, marked the hottest decade recorded by NASA. Human activities that release carbon dioxide and other heat trapping greenhouse gases contribute to climate change. The largest known contribution comes from the burning of fossil fuels- coal, oil, and natural gases for energy, and agriculture. Power stations emit 21.3% harmful gases into the atmosphere. A typical coal plant emits 3.5 million tons of CO2 per year. Coal plants in the US are also the leading source of sulfur dioxide. Burning coal causes smog, acid rain, and toxic rain. This acid rain damages crops, forests, and soils, and acidifies lakes and streams. Coal plants also emits 10,300 tons of nitrogen oxides per year which causes smog and makes or causes people to have chronic …show more content…
NASA has stated that the global surface temperature has warmed since 1880. Their measurements have shown since the 1970s with the 20 warmest years have occurred since 1981. If something is not done the long live greenhouse gases such as CO2 will continue to amplify global warming for centuries to come. If we do not cut carbon emissions extreme events will occur such as storm surges adding to rising sea levels and threatening coastal cities. There is a possibility for a more intense El Nino will set in. Governments and individuals need to adopt sustainable non-carbon energy sources and choose renewable power. Many studies show that we can reduce, reuse, and recycle so that we can save the planet

    With the ice caps melting, and the planet’s ozone layer depleting, mankind could be driving the Earth to extinction. The study of the earth and how it works allows scientists to develop new ways to try to save the Earth. While many debate the existence of climate change, it is a very real thing causing harm to our planet. The use of fossil fuels, and the development of new alternative energy sources could be the solution. Climate Change One of the biggest factors changing our earth is global warming.…

    There are several changes that are being predicted. There is high scientific evidence that global temperatures will continue to rise for decades into the future because of green house gases being produced by human activities. Scientists have concluded from research that a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century will occur. The future is predicted to have ocean acidification, over the past century the ocean water acidity has increased around 30 percent due to humans admitting more carbon dioxide into the atmosphere. Carbon dioxide absorbed by the upper layer of the ocean is increasing by two billion tons per year.…

    Global warming is a huge problem that is currently affecting the entire Earth. However, this climate change has been present for millions and millions of years, but recently it has been rapidly increasing. Many people are unaware of the resulting consequences of global warming, how they really are affecting this Earth, and what steps to take to create a solution. Many people also question who is to blame for this rapid increase. Are humans solely to blame for global warming, or is it bound to happen by natural causes?…

    One particularly noticeable consequence is the temperature variations happening recently. The Intergovernmental Panel on Climate Change (IPCC) has predicted the temperature will increase by two and one-half to ten degrees Fahrenheit over the upcoming century. In 2007, a report, also constructed by the IPCC, stated the increase of the globally averaged temperatures since the mid-20th century is “very likely” (with ninety percent certainty) from humans. Global warming caused by humans has been increasing and intensifying heatwaves and droughts. Research found from a 2015 study concludes that seventy-five percent of unusual, extremely hot days are from human-induced warming.…

    An increase in the earth’s average temperature is called global warming. It is an adaptation that is believed to be permanently changing the earth 's climate. Many scientists are trying to prove that how and why there is an increase in the earth’s temperature. Many greenhouse gases, and other human activities are considered to be the foremost cause of global warming. It is really clear that we are not taking a good care of our nature, on which we are dependent.…

    climate does change, it is almost always in relation to the amount of carbon dioxide in the atmosphere. According to Howard Lee, a geologist who writes for a website called skeptical science, stated that the earth 's climate has abruptly risen in the past, as it is doing today. He also says that these abrupt rises in earths climate has always been destructive for life on earth, causing mass extinction. The Permian period is an example of this. The Permian period is also known as the great dying because 90% of earths life was wiped out by a sudden release of carbon dioxide into the atmosphere.…

    Human Effects On Global Warming How do we, humans, affect the topic “global warming?” What is global warming? How does it affect the earth and living organisms? Global warming is a term used for describing a consistent change of heat temperature on our earth. It is also believed to permanently change the earth’s climate, making it warmer and warmer as time moves forward. It affects mainly sea and ice animals, scientists estimate that the arctic sea ice is melting 12% every decade.…

    Increasing levels of carbon dioxide from the atmosphere is making the water warmer which kills coral reefs. Some people argue that the global warming is just a cycle that the Earth goes through. In the article, “Global Climate Change” by Paul and Liz Downing, they claim that the Earth goes through a phase in which it becomes warmer for some time and then back to cool. This is because approximately every 100,000 years Earth 's climate warms up temporarily. These warmer intervals, called interglacial periods, appear to last approximately 15,000 to 20,000 years before we go back to a cold, ice age climate.…

    Over the last century, it has been proven that everyone has played a role in the effects of global warming. The introduction of new technology has caused a substantial amount of carbon put into the atmosphere, causing Earth to warm. The winter has become shorter and the summers longer and hotter. Ice caps have melted, leaving us worried about the rising water. Ultimately, it might have become too late for us to reverse the damage we have caused to…
