Informative Speech: A Speech Outline For Global Warming

Homero Castro Ms. Cabaj English IV, 3rd period 12 February 2018 Global Warming Global Warming is affecting the entire world. The issue of global warming is important because it’s affecting everyone.

Actually, one of the results of increased CO2 levels are the development of more weeds, pests, and diseases. As mentioned in an article called, “Effects of Climate Change on Agriculture” by North Carolina State University, “Weeds have become more prolific and are expected to invade new habitats as global warming increases.” The article also mentions that pests that may carry plant diseases will become more widespread resulting in herbicides becoming less effective (North Carolina State University). With these problems arising from increased CO2 levels, agriculture will be deeply affected.

More intense rains, hurricanes and high rising sea levels will lead to flooding and potential loss of property and life. The hotter summers will lead to frequent fires leading to higher levels of near-surface ozone and smoke which potentially would increase code red air. As the summers are heating up intense droughts would lead to an increase in malnutrition as in the long term fresh water will become scarcer. ("Global Warming : Feature Articles".

In another article written by Amanda Macmillan summarizes the effects global warming has on nature due to the cause of overload of carbon dioxide and forest deforestation. First, the text states earth’s rising “temperatures are fueling longer and hotter heat waves, more frequent droughts, heavier rainfall, and more powerful hurricanes”, which is not good news for us living here on planet earth. And it doesn’t stop there-there are also the effects of global warming creating even more “intense allergy seasons”, and the frequent sea level rise happening around the world.obviously these problems are not convenient for us we shouldn’t ignore this any more change must come. Other major examples found on a website called livescience.com it states “heavier flooding and precipitation” will come in result of global warming, and over the last 100 years the global temp has gone up .4 degrees celsius. These stats might not seem like a lot but they are having drastic effects on our

Global Warming causes and solutions The majority of scientists around the world have a fear of global warming and its effects on nature and humans around the world. Global warming is considered as one of the most threatened in our world today. This essay presents and explains the impact of global warming on earth and suggests to finding the best solutions can be done in order to minimizing those reason that affected on raising the temperatures to avoid this problem.

1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.

Global warming is a serious problem that refers to having too much carbon dioxide in the atmosphere. This problem interacts as a blanket, trapping the heat and warming inside our planet. Humans are used to burn fossil fuels such as oil, natural gas and coal for energy or log and burn the forests for creating new other products. The atmosphere by that is overloaded with carbon dioxide emissions (Climate Hot Map, 2011). There are some specific waste and agricultural management practices that increase the burden on earth by releasing other global warming gases.

On the other side, there is sharp decline in sea cover; glaciers and sea ice. Because of climate change, the earth is getting warmer, rain patters are changing, and snow and ice are melting at an alarming rate. As the global temperatures continue to rise, it is evident that we are going to see more changes in our climate and environment which changes are going to have severe effects on mankind and natural ecosystems. Over the past years, the Earth’s climate has been affected by natural factors that are external to the climate system, such as changes in volcanic activity, solar output, and the Earth's orbit around the Sun. In terms of the Earth’s energy balance, these factors primarily influence the amount of incoming energy and changes in solar irradiance which has contributed to climate trends over the past century.

One of the most important problems to this day is global warming. Global warming is the gradual warming of the Earth's surface and the lowest layers of the atmosphere caused by the greenhouse effect, which leads to global climate change. Climate has been changing since the Earth's past, but it is also considered that the current global warming is due to increased emissions of greenhouse gases. The last 100 years have seen the largest increases in temperature over the past 1300 years. People do not know how much they pollute the environment and what catastrophic consequences their actions could possibly bring.

It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossils fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, changes in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario. • Loss of Biodiversity: Human activity is leading to the extinction of species and habitants and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollution is crucial to the survival population is decimating.

The home to mankind and millions other species is facing the biggest threat ever: global warming, which is one of the most concerning issues in today’s world. Before going any further, it is very important to understand what the term actually means. Global warming is defined as “the gradual increase in the average temperature of the Earth 's atmosphere and its oceans” by Wikipedia. It is altering the earth’s climate permanently. Global warming has had drastic effects on the ecosystem and mostly not in a positive way because now it has reached a harmful level.

Persuasive Essay : Climate Change Recently, nations have been plagued by the constant emission of pollutants across the globe. These pollutants mainly include of carbon monoxide, methane, and sulfur dioxide. Together, these pollutants can cause damage and affect all forms of life. The melting ice caps, the hazards to general health, and the bleaching of coral reefs are many such dangers that are being caused by pollution.
