Do humans cause global warming or is it natural? Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the `earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. What is global warming? Global warming is an increase in the average temperature at Earth's surface (“global warming”). Global warming is all about adverse climate change caused by the trapping of greenhouse gases in the earth's atmosphere that affects biodiversity and poses a serious health hazard. Scientists have found strong evidence that human activities have caused most of the warming since the mid-1900 (“global warming”). Humans are responsible for …show more content…
All of the greenhouse gases contribute to the atmosphere trapping heat and warming the earth and warming the Earth has many effects. The earth being warmed, meaning from North Pole to South Pole, melts ice in the poles. The melting of the ice causes sea levels to rise and the effect of that is flooding and lost habitat for animals. Increase in temperature makes some of population of plant and animal species go down. Increase in temperature also affects the weather. When large storms hit land with these increased sea levels it causes large storm surges that can destroy anything in its paths. If temperatures continue to rise other natural disasters could occur ("Global Warming Will Produce More Katrina-Like Storms"). A warmer wetter atmosphere could spawn more tropical storms and there will be floods in places that do not get much rainfall. Humans could prevent these problems if they were to cut down on the use of fossil fuels and use more renewable energy. Renewable energy consists of wind, solar, and lunar power. Humans also could drive fuel efficient
The greenhouse gases in the atmosphere absorb some of this energy, while the rest is emitted back into space, as a naturally occurring cycle that repeats daily which is needed to keep the earth 's surface warm. The green house gases that humans are adding to the atmosphere are like the steroids of the climate system. The problem is that humans are producing far too much greenhouse gases due to increased human activities that demand the use of energy, which has led to emissions and an increase in greenhouse gases. An increase in these greenhouse gases in the atmosphere means more heat is trapped in the atmosphere, and less is emitted into space, which essentially warms up the average temperature of the earth. A small increase in temperature creates major effects to our environment, which is seen in the idea of climate change.
Water rising due to climate change is impacting people by causing islands to get flooded. This causes people to have to evacuate and find new homes, which can cause overpopulation in some cases (Doc G & H). Climate change is also impacting people because of health. The warmer temperatures cause there to be longer pollen seasons since the cold comes later and goes away sooner (Doc E). This makes for miserable and potentially dangerous summers for people who are allergic to pollen (Doc F).
If the situation gets worse enough, thousands, if not millions could die. Other than causing possible human death or harm, increased ocean levels will put more strain on the world’s agricultural systems since many farmlands will be contaminated with salt water. Also, rising ocean levels will lower land and water biodiversity. Imagine a world with no penguins, polar bears, or even predatory fish. This may become a
The increase in temperature is melting the glaciers; causing a steady rise in sea levels. In “The Big Thaw” by Daniel Glick, rising sea levels are shown as a major problem to some coastal regions of the world. Due to rising sea levels, small islands will soon be engulfed by the water. This will result in thousands of lives and homes being destroyed. Glick says “Tuvalu, a small country in the South Pacific, has begun formulating evacuation plans.”
B. Thesis: The causes of global warming and climate change are because of increased emissions of greenhouse gases, and the effects of this are rising temperatures and more severe natural disasters. II. Body A. Counter Claim: Most scientist and people believe that humans are the cause of global warming because of the emissions that they put into the air, but there is a small percentage of people who think that global warming is not caused by emissions at all.

Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for 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 can cause many changes in our environment. Polar ice caps can start to melt which can cause rising sea levels and can easily lead to coastal flooding on the eastern seaboard. There can also be affects on the types of storms that can occur if global warming continues. Scientists say that category three storms can turn into a more dangerous category fours. Farms and cities will face new pests, heatwaves, heavy downpours, and increased flooding.
Consequences of global warming Global warming is causing the glaciers to melt specially in rise in sea level would destroy the plants and other species as the area would get over-flooded. The animals would die from hunger due to the deterioration of forests and plants. Ultimately the people who have survived the flood and heat would suffer at the hands of hunger as the only two sources of food we have would get destroyed due to global warming.
Polar ice caps are melting, sea level is rising, wet places are drying, cold places are warmer, all of these things are caused by Global Warming. What is Global Warming? you might ask. Well Global Warming is a slow rising of the earth’s overall temperature. This means that it isn’t a drastic change and the world’s climate is getting heated up in a week.
Global warming also referred to as climate change is the gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants in the air today. There are two causes of global warming, human influences and also natural causes. Global warming is increasing day by day because of all the natural causes going on. A greenhouse is a glass building that contains plants in it that needed to be protected from cold weather. These greenhouses attract heat from many things like the
Human activities contribute to climate change by causing changes in Earth`s atmosphere in the amounts of greenhouse gases. Since the start of the industrial era (about 1750) the overall effect of human activities on climate has been a warming influence. The United States is the second biggest contributor of CO2 in our environment, however it is home to only 4.4 percent of the total population. In the event that everybody on the planet lived the way individuals do in the U.S., it would take four Earths to give enough assets to everybody. In many ways over time the effect that humans have on the climate is very bad and very dangerous.
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.
The ice from glaciers, the ice sheets and permafrost are already melting and will probably continue to melt at a higher rate in the future leading to rises in ocean levels (IPCC, 2014). Furthermore, it causes the emission of methane (also a GHG), stored mostly in the Arctic regions (Shakhova et al., 2007) which in turn leads to increased heat in the atmosphere, further aggravating climate change. GHGs cause the oceans to contain increasingly more acids, which damages coral reefs and negatively influences the amount of CO2 the ocean can absorb (IPCC, 2014). Weather conditions are becoming progressively extreme and a rise in floods, hurricanes and temperatures can already be measured and will further increase in the future (USGCRP, 2014). Weather incidents could destroy forests and swamps, which causes less CO2 to be absorbed naturally.
The unprecedented changes observed in natural environment during 20th century is the outcome of rapid industrialization and population growth occurred worldwide (Beniston, 2003).The over exploitation of natural resources (e.g. forest, water and land etc.) in recent past, attributed to environmental degradation, which in long-term disturbed global climate system and resulted into climate change. Climate change refers to any change in climate over time, whether due to natural variability or as a result of human activity (IPCC, 2007). This describes changes in the variability or mean state of the atmosphere over time scales ranging from decades to millions of years. The threat of human induced climate change presents a difficult challenge to
