Recommended: Effects on human activities by climate change
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 costing the world millions of dollars and is the biggest issue facing society today. Climate change is causing greenhouse gases to build up, ice caps to melt, etc. Some people believe climate change is not a big issue. For instance in the article “Gospel of The Climate Change Deniers” it is stated, “Barton a guy who called Al Gore ‘totally wrong’ about global warming and advised people to get shade to adapt to rising temperatures” (Kroll). Although, this is an appealing mindset, it is illogical because climate change has many more effects than just warmer temperatures. For example, Frank Ackerman: an economist known for his work in environmental economics and Dr. Elizabeth A. Stanton an environmental economist and
“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.” BARACK OBAMA, speech, Apr. 3, 2006. Climate change is not a theory contrary to what many individuals believe and is in fact confirmed by major scientific agencies such as the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) in the United States. Global Warming causes are mainly due to greenhouse gases that are trapped in the atmosphere and cause depletion of the earth’s ozone layer. Carbon Dioxide is a greenhouse gas, and although it is a necessary component in our atmosphere as it helps plants perform photosynthesis, too much of it causes ozone depletion and therefore climate change. Carbon Dioxide levels in the atmosphere have increased tremendously after the industrial revolution, which indicates that the major cause of this issue is due to anthropogenic activities.
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
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.
But the debate over whether climate change is real or not is over. The U.S National Academy of Sciences quotes, “Some scientific conclusions or theories have been so thoroughly examined and tested, and supported by many independent observations and results, that their likelihood of subsequently being found to be wrong is vanishingly small. Small conclusions and theories are then regarded as settled facts. This is the case for the conclusions that the Earth System is warming and that much of this warming is very likely due to human activities.” This suggests that there is a strong body of evidence from all around the world including record temperatures, rising sea levels, retreating glaciers and extreme weather events showing that climate change is occurring and it is mostly caused by human activities. According to Metz, “July 2012 marked the hottest month in U.S history, and drought expanded to cover 63% of the contiguous U.S. The average temperature was 25.33 degrees Celsius, 1.8 degrees about the 20th-century average, making the hottest 12-month period the nation had endured in 117 years of record-keeping.” This suggests that these record-breaking temperatures are the result of global warming. It is nothing else but climate

Many people dedicate their lives to spread the message about climate change being real. Even though some change in the climate is natural, many events that have happened cannot be explained away by nature. Climate change is causing damage to the world that is completely irreversible. Nasa says, “Most scientists say it 's very likely that most of the warming since the mid-1900s is due to the burning of coal, oil and gas. Burning these fuels is how we produce most of the energy that we use every day” (nasa). The energy that we use daily makes our life easier, but it hurts the earth. Why does the government still allow us to use these things? Science has shown us that sea levels are rising in many parts of the world. Warm weather is causing glaciers to melt which results in the sea level rising. Earth 's average temperature has been rising for the last century in a half; and there has also been a steady rise in ocean temperature since 1969. It is said that climate control is man made and it is dangerous. On the other side of the argument, many people do not believe that climate change is real. They argue that their has not been a big temperature change in almost two decades. They also bring up the point of there not being enough data in the climate history to draw the conclusion of what is happening in the climate now is abnormal. Scientist started to record climate change around the 1800’s which many people believe is not enough data to do a comparison. Another reason some believe that climate change is not real is because of some instances where a scientist predicts a date of a significant climate change never happens. Rinkesh writes, “ For example:- Al Gore predicted that all Arctic ice would be gone by 2013. But, on contrary Arctic ice is up by 50% since 2012” (conserve-energy-future). Many people find that these reasons are why climate change is not
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...
Others however believe that climate change is not a problem we should worry about and that scientist are making up this problem. People wonder what climate change is and if it is actually doing any harm to the earth. Scientist have been able to tell what climate change is and predict what will happen if nothing is done to stop climate change. The dictionary definition of climate change is a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
Climate change has been an up and coming issue with a lot of controversy surrounding it for the passed few years. It continues to grow and become even more controversial, as opinions are becoming more and more diametric. It generally seems as if there are two sides: one being that climate change exists as the fault of humans and the other being that it exists by natural occurrence. These opposing views are pretty extreme, but most people seem to be somewhere in the middle and a little less radical. I have found that all scientists openly testify that climate change is real, as do most humans, but there is deviation within where to place the blame (“Climate Change,” Encyclopedia).
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.
Global warming is an ever growing problem faced by our society today. It seems too often that people think that global warming is only a myth, but I’m here to say it’s not. Global warming is a serious problem with serious effects on the world as a whole. Global warming is caused by air pollution; this type of pollution causes the release of greenhouse gasses. The way greenhouse gasses effects the environment is they turn the shorter radiation that is easily absorbed into the ozone layer into longer radiation. This change to longer radiation makes it harder to absorb causing the heat to get trapped between the ozone and the earth. Although, there’re some positive effects of global warming there’re far more negative effects of global warming on the world.
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 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.
Carbon dioxide is an important gas that is vital for plant life. This compound is made of a carbon atom and two oxygen atoms. Only 0.0397 of the atmosphere is composed of carbon dioxide. Even though carbon dioxide only makes up a small percentage of the atmosphere, lately increases in the amount carbon dioxide released into the atmosphere have shown to cause an adverse effect on the earth. The rise in amount of carbon dioxide in the atmosphere has caused the earth’s temperature to steadily rise. The term used to describe this effect is called global warming or climate change. Climate change is not something new. Over the past nine hundred thousand years the atmosphere has gone through extended periods of global warming and global cooling. These
