We might disagree on the causes of global warming; however, we cannot ignore that it is happening. Although we still experience cold winters, average global temperatures has risen drastically for the past three decades. Polar ice caps are melting; as a result, sea levels are rising. Scientist predict more extreme weather in the coming decades, in fact, droughts will probably be more common. Also, flooding and tropical temperatures might cause large amounts of methane gases to be released, which could be disastrous for our atmosphere. Climate change may have human causes and also it might be a natural occurrence. Nevertheless, we must find ways to save our planet.
The source of global warming is a very controversial topic. Some scientists think that global warming is a natural part of the Earth’s cycle because the Earth has always had natural heating and cooling cycles. Other scientists believe that global warming is caused by humans dut to the greenhouse effect. The greenhouse effect is the accumulation of greenhouse gases such as carbon dioxide released from the burning of fossil fuels. These scientists believe
The argument against global warming is divided into two schools of thought. The first is that scientific evidence proves that the earth is not warming and the issue has been artificially manufactured. The second school of thought is that warming is occurring. However, this warming is naturally occurring regardless of how we treat the environment and this warming is beneficial to us for a variety of reasons which I will explain.
Climate change is caused by most human activities. Most of us humans harm the earth every day. Some may know what we do is harming the earth, but still do it, and some people may not have a clue. A research professor in the Learning at the Harvard Graduate School of Education said that a large, nationally
The theories used to “prove” that “global warming” may be a severe problem could be proven wrong. The causes of “global warming” are a great thing for essential life. All the causes and effects of “global warming” make up the Earth that people live on today. These causes and effects create a better planet for people to live in. Without
Global warming has been a major concern and has greatly affected the environment around the world for years. Andrew Revkin stated in a New York Times article entitled “A Closer Look at Climate Panel’s Findings on Global Warming Impacts” that climate change throughout the 21st century will lead to increases in ill-health in many regions, as compared to a baseline without climate change. There have been a number of debates regarding this controversial topic, though most of the scientific community can recognize the existence of global warming. Many often question if this effect on the environment is caused by human activity or natural cycles. About 95 percent of scientific studies prove that global warming is essentially caused by man.
Did you know that 97 percent of climate scientists agree that climate change in the last century is due to human activities? Global warming is a 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. Due to these things, we have encountered unusual climate changes, such as ocean acidification and the melting of ice caps. Global warming is real and can be reduced as well as affected by humans, but it is not a topic we need to prioritize.
The Global Warming theory has become increasingly popular over the past few years. Citizens of the world are being encouraged to be more environmentally conscious by others including politicians, celebrities, and world organizations. The problem with the theory lies in the fact that it has become more and more controversial as it gains publicity and attention. The basic concept behind this theory is that the earth was made with a balance of “greenhouse gasses”. These gasses are naturally occurring within the atmosphere and they essentially make the planet habitable by keeping it warm.
“Most of the observed warming that we have seen (verb) in the last 50 years is likely to be due to human activity, due to greenhouse gases,” claims Dr. David Karoly (noun), an expert in climate change. Some people believe that global (adjective) warming is just a naturally occurring thing on (preposition) Earth. However, humans are causing global warming because they (pronoun) are putting too much carbon dioxide in the air, the temperatures are increasing more rapidly than normal, and (conjunctions) the ice caps are melting at an alarming rate. Humans are the main cause of global warming.
Scientists who believe in global warming say that global warming is the result of carbon dioxide and other air pollutants collecting in the atmosphere like a thickening blanket, trapping the sun’s heat which causes the earth to heat up. In fact, according to Amber Jenkins, site editor for "Global Warming: Vital Signs of the Planet," meteorologists at NASA (National Aeronautics & Space Administration) have reported that “Earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years. Studies indicate that the average global temperature has increased by approximately 0.5-1.0°F (0.3-0.6°C) over the last century” (Jenkins).
Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:
Although some believe that Global Warming has been created due to manmade pollutants, I believe that Global Warming is a natural process that has been accelerated due to the excess emissions of pollutants from nature and manmade devices into the atmosphere. The world has been said to be on a cycle of global warming and cooling, this process can neither be stopped nor prevented, but it can be accelerated with the addition of non-natural emissions from automobiles and factories; because this is a natural process, even if constraints were to be put on the amount of pollutants released into the air global warming could not be prevented—it could only be slowed. When the inevitable happens and global warming occurs, there are many
The Global Warming Debate We are polluting the atmosphere and with an increasingly wide range of polluting substances and these are due to the fact that there are now so many people and their human activities are altering the chemical compositing of
Global warming has become a well conversed topic among scientists and peoples in the world today. There are extremists who do everything possible to stop contributing to the warming, but the average person does little to alleviate the issue and in many cases refuses to acknowledge that there is a problem at all. Dating back to millions of years ago, even before humanity was born, the world has always experienced one form or another of warming; so the warming seen today is not as bizarre as many may think. The prevalent saying that history often repeats itself, is no joke when discussing global warming. As to what is kindling the current warming, that is where a query is imposed. Scientists from around the globe have theorized close to every possible contributor to the warming seen today, and the conclusion that present occurrences of global warming are being evoked by human interference has become evident.
Some believe global warming isn't a man made problem, but just a cycle of ‘weather patterns’. For example, our now president -Donald J. Trump- doesn't consider climate change to a threat to the inhabitants of earth. Our president also said that global warming is a ‘hoax’.
