Title: The Impact of Global Warming Purpose Statement: To inform my audience about how global warming is impacting the earth. Central Idea: Data shows that all throughout history, the temperature of our planet has changed over and over again for natural reasons. Holli Riebeek, education and outreach specialist at NASA, stated that these changes are due to small shifts in the Earth’s orbit and the Sun’s energy levels varying throughout time. Today, unfortunately, with the average temperature of the
The effects of climate change have become more apparent than ever within the last 100 years. Increasing climates have been proven; with the warmest temperatures in 30 years being recorded (Houghton, 1994). Suggested cause of this increase is population change, the ever increasing demand for natural resources to sustain economic growth has resulted in exploitation of ecological systems at a rate never recorded before. These huge changes to the planet will have a knock on effect to individual and global
becoming one of the many worldwide dilemmas facing our planet. The rapid rate of deforestation is reaching disastrous limits as the demands for resources far exceed supplies. Rainforests provide a home to many species of plants, both known and unknown. Our dependencies on tropical plants are vast ranging from the daily essentials of food and shelter, to cures for cancer and possibly AIDS. As destruction of the rainforest continues, the effects on plants are immense through the loss of genetic
In two recent articles published in National Geographic and NASA Earth Observatory, “Signs From Earth: No Room to Run” and “How Will Global Warming Change Earth?”, both articles serve to raise the reader’s awareness and challenges us to see deeper into the serious implications global warming has, not only in our lives, but also into the life of our fragile ecosystem as well. And while both articles share a distinct similarity in delivering to a audience a message that is both omniscient and foretelling
Over the course of the years global warming has become a threatening issue that scientists and the government have been cognizant about. Global warming is the term used to describe a gradual increase in the average temperature of the Earth 's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. The earth periodically warms up and cools down. The Earth is currently going through a warming trend that coincides with the industrial revolution. This threat
with carbon dioxide and other greenhouse gases being emitted into the atmosphere. These changes to the worlds ecosystems and could involve key human health problems. There is worldwide scientific consensus and proof that climate change is real, evidence proves there has been 7 cycles of glacial advance and retreat, since the beginning of the modern climate 650,000 years ago. The evidence of our changing climate is from many forms of data collected over years ago [EV]. According to this evidence, we are
doubt, our planet as we know was not the same a century ago and it will not be the same a decade from now. Due to this perpetual evolution of our planet’s natural cycles, its inhabitants are forced to choose between adaption or extinction. Meanwhile, an invasive species, or humans, has started a chain of disasters that are accelerating global changes and, in extension, the crucial selection of existence. Over the years, the field of natural science has increased human knowledge regarding our negative
concerns of scientists, environmentalists, and people of this planet when it comes to environmental issues. Environmental issues is something that is discussed frequently in the news, in politics, and in classrooms around the world. More and more we are becoming informed and aware of the current and ever facing environmental crises that are taking place around the world today. Some scientists and environmentalists believe that many things within our lives daily contribute to the growing detriment of the
Resolving the Global Warming Problem "It is our attitude at the beginning of a difficult task which, more than anything else will effect the outcome." Global Warming according to Microsoft Bookshelf nineteen ninety eight edition is " A conjectural greenhouse effect on earth that is attributed to deforestation and industrial air emissions"(MS Bookshelf 98). Global Warming could be one of the most important issues of the century. As global warming becomes more and more of an issue, the factors
Global Warming Global warming is the ever growing tension and a controversial issue that is debated widely for the past few years. There are many critics and disbelievers still present in the politics and science field , who do not think that this issue is increasing at such a large scale. It may be due to the lack of evidences in this field, that resulted into this thought that it is the natural process that is evolving on this planet in cycles. In this present era the existence of global warming
