Climate change has been nothing, but controversial in the last fifty years. Climate change is a change in the average weather of a region or city. Scientists have opted to use the term "climate change" instead of global warming because as the Earth's average temperature changes, winds and ocean currents move heat around the globe in ways that can cool some areas, as well as warm others. There is an ongoing dispute about the effects of humans on the global climate and about what policies should be implemented to avoid possible undesirable effects of climate change. Ninety-seven percent of published scientific research concluded that climate change is real, problematic for the planet, and has been exacerbated by human activity. But what about the three percent that contradicts that? …show more content…
They believe that humans have caused most of the past century’s warming by releasing greenhouse gases; their levels are higher now than in the last six hundred fifty thousand years. Greenhouse gases happen when sunlight shines onto the Earth's surface, where it is absorbed and then radiated back into the atmosphere as heat. In the atmosphere, “greenhouse” gases trap some of this heat, and the rest escapes into space. Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change. CO2 is absorbed and emitted naturally as part of the carbon cycle, through plant and animal respiration, volcanic eruptions, and ocean-atmosphere exchange. Human activities, such as the burning of fossil fuels and changes in land use, release large amounts of CO2, causing concentrations in the atmosphere to rise. The rapid rise in greenhouse gases is presenting two major problems: extreme weather and melting of ice sheets. In addition, our sea levels could potentially rise too high, possibly flooding
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
Climate change is a term used to describe the increase in the average temperature of the earth’s surface and has been a major problem recently. Our world is constantly changing and therefore so is our climate, as our country industrializes we create more greenhouse gases from the immense human activity being produced. “These gases get into the atmosphere when coal, natural gas and oil is burned for energy and over the last century the burning of fossil fuels like coal and oil has increased the concentration of carbon dioxide… the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases.”(NASA 1). Climate change is causing global warming that causes the earth to heat up rather than
For a majority of people, it isn’t new news that the Earth’s climate is changing and increasingly getting warmer. For quite some time now, people have been arguing about what the actual causes are and what role humans have played in the current condition of the earth. A good bit of people seem to be in agreement that due to the actions of humans, the earth’s climate is increasingly getting worse and that if things don’t change, than everyone living on earth will be facing the consequences. However, this is not entirely true. The fault of climate change does not fall solely on the shoulders of mankind, but on the earth as well.
Climate change is a major issue that is only going to get worse. Climate change is a change in global or regional climate patterns. It has become more apparent since the mid to late 20th century onwards and is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change has been an important issue for decades that has effects on the environment and people of the world with the end result potentially being catastrophic. Although many believe that prolific use of fossil fuels is the direct cause of climate change, there are many more underlying causes including population expansion as well as irresponsible consumption of natural resources that have
For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.
For over a hundred years, scientists have been carefully gathering and verifying data on the earth's temperature. The latest data reveals some striking trends:All 10 of the warmest years on record have occurred in the last 15 years The 1990's have already been warmer than the 1980's- the warmest decade on record The global average surface temperature has risen 0.5 degrees (site source)For the first time ever, the Intergovernmental Panel on Climate Change, the authoritative international body charged with studying this issue, concluded that the observed increase in global average temperature over the last century "is unlikely to be entirely natural in origin" and that "the balance of evidence suggests that there is a discernible human influence on global climate."The Earth's climate is the result of extremely complex interactions among the atmosphere, the oceans, the land masses, and living organisms, which are all warmed daily by the sun's enormous energy. This heat would radiate back into space if not for the atmosphere, which relies on a delicate balance of heat-trapping gases, including water vapor, carbon dioxide, nitrous oxide, and methane, to act as a natural "greenhouse," keeping in just the right amount of the sun's energy to support life.For the past 150 years, though, the atmospheric concentrations of these gases, particularly carbon dioxide. Have been rising. As a result, more heat is being trapped than previously, which in turn is causing the global temperature to rise. Climate scientists have linked the increased levels of heat-trapping gases in the atmosphere to human activities, in particular the burning of fossil fuels (coal, oil, and natural gas for heating and electricity; gasoline for transportation) deforestation, cattle ranching, and rice farming.
The clock is ticking! Global Co2 emissions have increased exponentially since the industrialization of today’s developed world. Emissions have now passed the absorptive capacity of the earth and are accumulating in the earth’s atmosphere, warming the surface of the earth and inducing localized climatic changes. Climate change is often a localized issue. Many regions of the world will continue to become hotter, while others may experience highly variable weather patterns. Climate change poses a serious threat to ecosystems, economic sectors, and human welfare. Although almost entirely caused by the developed world, climate change will disproportionally affect the world’s poor.
What is global warming and what does it mean. Global warming is any substantial change in Earth’s climate. Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases. Global warming is also known as the greenhouse effects. The increase of human population has affected the world. The growth of our population has increased our use of fuel, land and manufacturing. All of these are causing an increase of emissions to go into the Earth’s atmosphere, which is causing global warming.
Scientists still do not know what exactly is heating up the earth. Some say the earth is going through a natural cycle because the earth has gone through cold periods as well as hot periods. Mounting evidence is saying that humans are to blame for the rise in temperatures over the past 120 years. When we burn fossil fuel, oil, gasoline, and natural gas to run power plants, cars, and heat homes, we produce carbon dioxide. An increase in carbon dioxide magnifies the greenhouse effect. All this energy accounts for 80% of society’s carbon dioxide emissions, 25% of methane emissions, and 20% of nitrous oxide emissions. In 1994, the U.S. emitted one fifth of all the greenhouse gases in the earth. Carbon dioxide amounts are now 360 parts per million today, verses 315 per million parts in 1958, when modern technology started, and 270 per million parts in pre-industrial times. Sc...
Climate Change, or “Global Warming,” has been a point of argument for many years. There are many theories for how and why the climate has changed and been affected. The big question is, Are humans really causing the climate to change or is it some other cause no one is willing to see? All around climate change or “Global Warming” is a cycle of the Earths atmospheric temperature, because statistics show that this cycle has been occurring for millions of years. There is no direct evidence supporting the claim that humans have any direct effect on global warming. The IPPC, Patrick Gonzalez, and Bharat Raj Singh have been giving people hand-picked information on climate change to control what we think. The people need to have all the information in order to make a sound decision on how they feel.
Throughout the years, climate change has become a topic that people are getting more concerned about as the years go by. Climate change has an effect on the temperature around the world which cause nature to change drastically. Cars, airplanes, coal and other man-made things are considered to enemies to climate change. Although it is a theory, other people think that climate change is something that is occurring naturally by nature. Mankind has been accused of causing different amounts of damage to the world in different ways. Humans ca/ sxsxxxxxxxxxxxssx;2nnot predict what nature has planned for us so we cannot jump to conclusions on the way nature works. Climate change could be affected by something on earth or may not, but it is yet to be
Climate change has become a very sore subject for many scientists all around the world. There are some people that believe climate change and global warming are just a simple myths for gullible people, that humans have no affect at all on how our environment is changing. On the other hand, it is also told that 97% of papers taking a side on global climate change caused by humans agree that it is happening (Wayne). Many people read the evidence and can clearly see that humans are causing climate change not only to speed up but cause so many things to change in our environment as a result of it.
What will happen to planet Earth as years pass by? The world will eventually fall apart as the years go by because of many natural and manmade causes. One of the most impactful causes to the Earth’s eventual downfall is climate change. Climate change is a long term change in the weather that affects many parts of the Earth such as the arctic, extinction of animals and more terrible acts. Climate Change will affect the Earth negatively due to its causes of natural disasters, health effects to humans, and global warming.
The change in climate has been a topic of controversy across the world throughout the past years. Scientists have done research on how climate changes has changed throughout the years around the world. In the past few years, research shows that climate has changed dramatically in the world. Although climate change is something that occurs normally in nature, there has been substantial evidence that mankind is a contributor to the dramatic increase. Most countries around the world have got together to discuss how to reduce mankind’s contribution to climate change, but there is other countries that still do not consider this as a problem. Research conducted by scientists have supported the idea that climate
Climate change is serious problem in the world. The major problem caused by climate change was having a severe influence in the coastal areas. The UN (2006) report that more than 50 per cent people live in cities at present, and this number will steady grow in the next few year. Climate change is due to increasing car exhausts and factory emissions that lead to global greenhouse gas emission to rise sharply. For this reason, the earth has a number of environmental problems, such as the sea level rise, extreme events and unreasonable energy use. This essay will explain some major problems of climate change, and analyze the impacts of economic and environmental. The essay argues climate change caused by human beings and rapid urban development.
