The Future Effects of Global Warming Introduction After several years of scientific debate over the existence of global warming, most experts now agree that global warming exists and may have devastating effects on Earth’s climate. Global warming will influence and/or cause heat waves, polar ice caps melting, flooding, extinction, and droughts. Social, Historic and Intellectual Context of the Study The existing research literature suggests that global warming is going to greatly affect the Earth’s climate. Global warming is defined as an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (Merriam-Webster Online…show more content…
This study assumed that species could migrate. Thousands of species could possible become extinct unless there is a reduction in the greenhouse gas emissions produced. Thomas’s data suggests that at least 1/5 of all living things will become extinct because of the existing levels of greenhouse gasses. (Flannery 183) 1.25 million species will be extinct by 2050 according to ecologist Chris Thomas. (Singer, Avery 75) Droughts will occur more frequently and will be more intense as global warming progresses. Global warming does not cause droughts. Some areas are naturally more likely to have droughts than others. Global warming does make droughts more intense and longer though. With a warmer climate, water will evaporate quicker and there will be more precipitation and that sounds like relief for droughts but it produces the opposite effects. Although there will be more precipitation in some places, that means that there will be less in others. In higher temperatures water evaporates quicker from the soil and plants. Because of this, droughts can occur even if the rainfall is constant. Winters will be shorter and warmer and because of this there will be less snow. Lakes and rivers are usually replenished by the snow melting in spring. These shorter winters may not provide the spring melt needed to replenish the lakes and rivers.
