Whether human beings are responsible for the global climate change has been debated for decades. The climate change is the long-term change of weather in decades to millions of years. Some people argued that the global climate change is part of the natural climate cycle of the Earth or is caused by the radiation and heat from the sun. However, United Nations has claimed that “Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes” (United Nations News Centre).
Many lines of evidence indicated that the global climate has been changed. New highest temperatures have been recorded during the summer in the past few decades worldwide; while, the lowest temperature records have been repeatedly updated during the winter. At the beginning of 2014, the northeastern United States was suffered from severe snowstorm; New York City had a foot of snow and New England had about 18 inches (Guariglia). Meanwhile, the entire northern hemisphere, including Europe and Japan, was also stuck by deadly snowstorms (“Europe Battens down Hatches”). In addition, the frequency and intensity of hurricanes increase recently. One of most deadly and destructive Atlantic tropical cyclone is Hurricane Katrina that swiped New Orleans (Knabb, Rhome, and Brown 1-2). Furthermore, 2011 Tohoku earthquake and tsunami, also known as Great East Japan Earthquake, happened on March 11, 2011 in Japan. The biggest disaster caused by this earthquake was the catastrophic failure at Fukushima Nuclear Power Plant, resulting in that radioactive materials have been released into the Pacific Ocean (Oskin). It has been wid...

...years ago than today while there was a natural cycle between ice ages and warmer interglacial periods. The only explanation that the temperature can have become lower on Earth is greenhouse effect from CO2, without the greenhouse effect there will not be an enormous change (“A Natural Climate Cycle”).
Global climate change had a serious impact on all living creature on Earth. Many lines of evidence suggests that human activities are the principal causes for global warming, such as burning fuels and cutting down forest, and those destructive activities to the Earth are still continuing to grow. There is only one Earth; once it is destroyed, then most likely all living creature on Earth will die. Therefore, people should ride less and use more public transportation; factories should reduce emissions to the way they live, which can become a huge change in the future.
Climate change is temperature increasing over a long period of time. Climate is imoortant to both humans and ecosyestems in order to thrive. One slight change can disrupt an entire ecosystem. Most people recognize that greenhouse gasses such carbon dioxide have been contributing to climate change. Greenhouse gases are part of earth’s many natural processes. Greenhouse gasses are important to keeping the earth at an overall warm temperature. When When sunlight shines down to Earth, it warms the surface but after so much warming, some of the heat goes right back out into the atmosphere. Some of the heat hits the greenhouse gases. When this happens, the molecules become excited and release even more heat. The issue of climate change has been
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
Climate change is a change in global temperature and regional climate patterns. At the turn of the 20th century, there has been rising issues about climate change, arguing that global warming and climate change is an issue worsened by the human race. Change in climate is a natural process in which changes from season to season and even fluxuates over thousands of years. Over the time frame of the last 650,000 years there has been seven cycles of glacial advance and retreat (Global Climate Change). It could be argued that climate change is a natural process and the Earth is suppose to change its temperature from hot to cold. Yes, that is true. However, the rate in which the temperature is changing is something this Earth has never endured. In
The effects of climate are felt throughout the world, all living things are affected with it. The effects of climate change are affecting directly the human life. It has been noticed that around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. The world compares to century ago, it has changed drastically and it is becoming worse with climate change. Climate change will rapidly alter the lands and waters which we all depends upon for survival which will leave our children thus the future generation with a different world. In the time to come if not much is done for the case of climate change, There will be shortage of food and drinks, many new illnesses and diseases and some part of the world will become in appropriate for living things to live due to natural disaster. It can be that with the rapid Global warming and climate change, one-fourth of Earth’s species could be headed for extinction by the year 2050.
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
There are so many factors in today’s growing population and its action that contributes to the environment. With the rise in population there is also increase in the needs and demands resulting in more production of food and assets. Most of the actions of human lead to increased environment risks which in return will only effect the livings of this planet. Currently mostly all individuals have at least one form of vehicle for transportation. There is increased industrialization and requires a lot of energy which comes from fossil fuels as the need for oil increases to fuel large amounts of humans daily work and chores. The climate change is no mystery, it is known to be cause of various human actions trying to satisfy their needs while putting
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
In theory some parts of the world might benefit, from a human point of view, due to global warming. However, at current rates of warming, local ecosystems will collapse and any objective measure of global benefits versus suffering would show much more suffering than benefits gained.
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted
According to Mr. Steffen, “The primary cause of the observed changes in the Earth’s climate are human activities—mainly the burning of fossil fuels” (Steffen, 2013). The process of burning fossil fuel unleashes a huge amount of greenhouse gases, especially carbon dioxide, to the atmosphere, disturbing the balance of greenhouse gases in the nature. As stated by Slaght, “The accumulation of greenhouse gases in the atmosphere due to human activities will change th...
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
“The temperatures on this planet have always fluctuated naturally on this planet. Looking back over the past 100 years, the earth warmed from 1900 to around 1940. There was global cooling after that until the late 1970’s.” (Scherer 20) The people who say this do not understand that there are weather patterns, but the pattern that is going on now...
In conclusion, global climate change is a very long discussion with many ways to improve the environment, but a long journey to finding a solution. Although we can 't do away with our main sources like power plants, cars, and factories we must continue to find solutions to making our environment safer and suitable to live in. Hopefully in the near future we will have a better understanding of how to address our global climate changes, but for now, we can focus our ideas on preventative ways to not harm ourselves and our
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors. I...
Global warming is one of the most serious issues that the human species face today, yet the majority of the population does not pay attention to it. People are not aware of the dangers and do not care about it much because the main effects will affect the next generation and not themselves. Global warming is happening and it is the reason for changing weather and weather extremes such as earthquakes, floods and wildfires. Global warming is caused by societies lifestyle and these lifestyles destroy the environment and affect the whole world. The use of cars, trains, planes, as well as wasting energy for people’s entertainment has a price; this price is that society is in danger.
