Throughout the course of history the earth’s climate has dramatically, changed within the last 650,000 years, there has been seven cycles of glacial advance and retreat. “In the past two decades, the scientific community has reached an overwhelming consensus those human activities are causing changes to the global climate.” (David B. Resnik). There has been a massive increase production of carbon dioxide, methane, and other greenhouse gases in the last century that has caused the climate change around the world. “If humanity does not start significantly reducing greenhouse gas emissions, average global temperatures will likely increase by several degrees Celsius in the next fifty years, which would lead disastrous environmental consequences, such as flooding of coastal areas, increased numbers of powerful hurricanes, desertification, decreased agricultural productivity, and loss of biodiversity.” (David B. Resnik). The main driver of today’s warming is the combustion of fossil fuels. These are hydrocarbons that heat up the planet; this is known as the greenhouse effect which is caused by the interaction between the earth’s atmospheres and the radiation from the …show more content…
The argument of this controversy is “are humans the main cause of global warming?” “In its 2013 fifth assessment report, the IPCC stated in its summary for policymakers that it is “extremely likely that more than half of the observed increase in global average surface temperature” from 1951 to 2010 was caused by human activity. By “extremely likely”, it meant that there was between a 95% and 100% probability that more than half of modern warming was due to humans.” (Carbon brief). Human activities, such as the combustion of fossil fuels are altering the climate system. Another reason how humans affect the cause of global warming are human driven changes, such as deforestation, urbanization, and shifts in vegetation
Almost anyone who will read this essay has undoubtedly heard of the climate phenomenon Global warming. Global warming is a topic that gets discussed very often nowadays, most notably during political debate and discussion. Politicians use certain stances on global warming to appeal to voter’s emotions and logic in order to gain votes and support for their campaign, however climate change is nothing new, during the past several hundred thousand years the Earth has heated up and cooled down and even experienced so called “ice ages”, which is a period where glacial deposits located at the northern and southern hemispheres have grown due to dramatic global cool downs. Don’t be confused by climate terminology though, the global warming so widely
People may know about climate change and the drastic changes it is having on the environment, but what they may not be aware of is that another degree increase in the world’s average temperature will cause even bigger problems for people all over. Climate change is long term shifts in temperature and patterns in the weather. Greenhouse gasses, gasses that trap heat in the atmosphere causing it to warm up are at an all-time high due to humans and the amount of fossil fuels we use. The most crucial result of climate change is global health, but animal endangerment and the rise in sea levels are also very important effects.
Do you often hear things like "we are killing our planet" or "global warming is a massive problem" from your local hippies? I 'm sure you must accept the common misconception that humans have made a huge impact on climate change, well I beg to differ: humans are actually not the main reason to climate change. In this essay I will explain as to why climate change isn 't caused by humans and why you should change your perspective on the topic. By analyzing that Global warming is natural, sea levels have been steadily rising for thousands of years, and CO2 has little impact on global warming, it becomes obvious that climate change was not cause by humans.
Climate Change This quote said by Washington State Governor, Jay Inslee shows the severity of climate change “We are the first generation to feel the sting of climate change, and we are the last generation that can do something about it.” “On Earth human activities are changing the natural greenhouse of the Earth.” (A blanket around the Earth). Burning fossil fuels is causing carbon dioxide to be released into the air.
Annotated Bibliography: How Climate Change Is Affecting Our Planet Controversy statement: Climate change is been debated for over centuries now. People all around the world are taking action and reducing burning fossils to minimize the gasses in the atmosphere. Many people believe that climate change doesn't exists. But there are a lot of controversial topics that proves that climate change is real. In my opinion, climate change is slowly killing us and destroying our planet.
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
Global Warming Proposal Introduction The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer.
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.

We were taught that the major cause of global warming is pollution generated by mankind. Which is correct, but what's the main source? Perhaps the burning of fossil fuels, such as cars and factories, is the leading cause of global warming? What about the tons of debris accumulated every year, does anyone believe that that's the major cause? But what if I told you that the major cause of climate change is not actually the car or bus you take to school or work everyday, or the insatiable amount of plastic bags collected from every trip to the grocery store which inevitably end up in our oceans, or not even the lights you leave on twenty four hours every day of the week, every week of the month and every month of the year.
This problem is controversial because some people believe that that global warming isn 't real and others believe it is. There is evidence that global warming is real because some scientist agree that the earth 's rising temperatures is due to all of the pollution. My opinion on it is that it is clearly real and we need to do something to stop it. If we do not stop all of the pollution in this world, it can affect everyone 's way of living in the future.
One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.
Perhaps less obvious but no less ominous a threat to the environment are the general increase in temperatures worldwide and the resulting climate changes. This phenomenon, known as global warming, could have serious negative effects on humans and all other living things on Earth. Global warming is a complex problem, and governments have had great difficulty deciding how to address it. Some people think that it is the work of the world where nothing we do can ether change it or anything we do will prevent it. While others say that the
So What Causes It? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth 's atmosphere. Think about what happens when you open your car door after the windows have been rolled up on a hot day.
