Global Warming causes rising sea level from glacier melting, unusual weather, increased temperature, droughts and floods, changes in ocean currents and climate shifts. I believe that global warming is the human fault because humans create more pollution by burning fossil fuels, expanding the greenhouse gases and cutting down and burning trees also release carbon dioxide. Releasing such gases into the atmosphere not only effects the atmosphere itself but also effects the entire earth and its population.
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect. Due to more greenhouse gases in the atmosphere, more heat is trapped which makes the Earth warmer. Global warming is the biggest threat being faced by mankind today. "Gases created through human industrial and agricultural practices (primarily carbon dioxide from burning fossil fuels and wood, as well as methane, nitrous oxide, and chlorofluorocarbons) increase the heat-reflecting potential of the atmosphere, thereby raising the planet’s average temperature."
The gases in our atmosphere control the Earth's temperature. It starts with sunlight (a form of energy), the energy is absorbed by land and water and the rest is reflected back to space. The Earth's surface warms up and gives off energy in a different form called infrared radiation. This energy is released back into space and some of this energy is trapped by the greenhouse gases. They trap it in the atmosphere before it can escape which keeps the Earth warmer. Without some of the greenhouse ga...

In conclusion, I believe that global warming is caused by humans. The more fossil fuel we use, the more it goes into the atmosphere. Also, too man trees are being cut down which is called deforestation. The trees that are being cut down release CO2 which goes into the atmosphere also. The trees absorb the CO2 but since all of the trees are being cut down, there arent enough of them to adsorb the CO2. The last reason humans are at fault is that us humans expanded the greenhouse effect. Meaning, due to our daily activities, we increased the concentraion of the greenhouse gases which is definitely not good. The natural causes of global warming is variations of the sun's energy reaching the Earth. Volcanic eruptions cause gases to go into the atmosphere and the 11 year solar cycle, the sun and climate are going in opposite directions.
Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:
Before a person can tackle handling the concept of global warming, they first must analyze the true definition of what it is. Climate change periodic modification of Earth’s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth 's system. (britannica) Since all 196 countries in the world have to share the oxygen and carbon dioxide, we all should take a part in the responsibility of taking care of earth. On November 6, 2012 President Obama said that we want our children to live in a world without the destructive power of a warming planet. The biggest challenge we face is not only saving a warming
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
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.
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
...lso that human activities play key roles in global warming. I believe Mankind is responsible for the increased amounts of natural gases already in the atmosphere accelerating global warming to take place. This is because humanity is the key contributors of adding large amounts of greenhouse gases to the Earth’s environment. The greenhouse gases accumulate in the atmosphere and traps heat, which increases temperature causing global warming. And the effects of global warming are widely seen in Canada, causing extreme weather and flooding.
Climate change is one of the most discussed topics of the twenty-first century. Although this subject is very often on the daily basis of lots of people, most of them do not know much about it. So let us define climate change. People think that climate change is the same thing as global warming. However, global warming only represents one aspect of climate that is temperature. Climate change is any significant change in temperature, precipitation, or a wind pattern that occur over several decades or longer.
The Earth is currently locked in perpetuating spiral of climate change. While the global climate has unarguably been changing since the dawn of it's manifestation, the once steadied ebb and flow of climate change has become increasingly more unpredictable.The risk of rising sea levels, and drought plaguing the fresh water supply, during the time that flooding and sporadic storm conditions turn once fully inhabited regions into uninhabitable death traps. Climate change catalyzed by human's increased production of carbon dioxide, is more noticeable than ever in our recorded history (United States, 2014 National Climate Assessment). Thankfully however, with the changing weather conditions due to carbon related emissions, the change in public opinion about their personalized influence on climate change is also increasing. Kevin Liptak Jethro Mullen, and Tom Cohen note that In reaction to the most recent governmental report on climate change, even the U.S. government believes that a stronger approach needs to be taken to correct our self-generated cataclysm.
In the modern era, climate change is a variation of weather over a long period of time, and it is the most important and controversial global issue. It is arguable in different positions, especially on science, culture, and politics. These three fields all cause a lot of latent concerns. The science of climate change brings out several harmful phenomenon, such as global warming. With respect to the climate change, the culture of humanity may be changed because the changing climate is the most important key factor of forming today’s human societies. Instead, climate change is now a political issue, which will affect the public attitudes directly. In other words, it means the government tends to review and provide latest information in order to adapt and retard the climate change. Over a long period of time, climate change has been taking place because of human activities that affect the scientific, cultural, and political sides.
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
Global warming is the unusual change in the earth 's climate. Over the last fifty years, it has
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
Global warming is a serious problem with two major effects: increasing sea level and degradation of wildlife. Increase in sea level affects the entire landmass of the earth. According to NASA, the polar ice cap is melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s (Oskin). The amount of water is more than the land on our planet.
Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change). Simply, global... ... middle of paper ... ... of extreme weather and melting ice caps are indicators of global warming.
Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth. As for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
