Earth’s carbon levels have followed a natural cycle throughout the past 800,000 years where the carbon dioxide concentration varied from 180 ppm (parts per million) and 280 ppm which resulted in several changes in the environment.. In the grand scheme of Earth, these changes are miniscule and have stayed within the natural cycle. But when looking through the eyes of humans, these changes are drastic causing ice ages, draughts, and rain for years (Goldstein 6). During the last century carbon dioxides levels in the atmosphere have become significantly larger than they ever have in the past 800,000 years. Today these levels are at 390 ppm and show no signs of stopping which will cause temperatures to rise because carbon is a greenhouse gas. When a greenhouse gas, such as carbon dioxide or water vapor are present in the atmosphere, they absorb the heat that the Earth is giving off, creating a thermal blanket over Earth trapping in heat (Houghton 20).
Now that the problem has been identified, determining the source of the problem becomes much easier. The human population is growing exponentially, in 1990 there were about 5.2 billion people on Earth, and in 2010 there were 6.8 billion people on Earth (Total Populatio...

- The planet Earth goes through cycles in every aspect of its environment from temperature, to water levels, to levels of carbon dioxide in the atmosphere. There has always been a limit to the levels of carbon dioxide in the atmosphere. The Earth is like a human body. If a human does not take care of their body through healthy eating and workouts, they become unhealthy and may have health problems. As with Earth, if Earth takes in more heat than it can let out, or vice versa, there will be global climate changes.... [tags: Global Warming Essays]

- Climate change is a worldwide issue that has been raised for decades but which is yet often relegated to a position of secondary importance. However, the attention given to the politics of climate change has been increasing over time, as the consequences of decades of inaction are about to be experienced. Nevertheless, for many, politicians and the media have failed to underline concretely the importance of addressing climate change. It is not the case of numerous novels, films and plays, as well as photographs and other art forms, that have aimed to depict global warming.... [tags: Global warming, Al Gore, Climate change]

- What The World Says About Climate Change. In his article, “The 97% Solution”, Ian Tuttle provides the scientific evidence that cast doubt on the claim by the White House that, “Ninety-seven percent of scientists concur and agree that there is global warming and anthropogenic impact.” Since the satellite measuring the temperature shows no significant warming change for the last 19 years, global warming alarmist called the situation “The Pause.” On the other hand, 97% of climate scientists declare that the earth is warming up, and it is mainly a result of human activity....

- Ethics on Global Warming 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.... [tags: Greenhouse gas, Climate change, Carbon dioxide]

- Climate Change: Causes, Effects, and Solutions The earth has experienced climate change for the entirety of its existence. For billions of years, this change has occurred at a relatively slow pace, with exceptions being caused by events such as large scale volcanic eruptions. Now, humans are the cause for high rates of climate change and damage to the environment. This is beginning to have damaging effects on not only us, but the world around us, and we are only just started to take action. Efforts to reduce climate change would be more realized if not for the resistance of many due to misconceptions, money, and a reluctance to change....

- Climate change is a change in global or regional climate patterns. Most of the cold extremes of the world is experiencing warming at a more rapid pace than its warming extremes. In fact, the true cold season now exists in only the polar extremes of the African continent. Western Africa and Guinea are found to also face a reduction of precipitation while its neighboring regions, although also affected with reduced rainfall, are more prone to extreme rainfall, indicating the effect of the change global warming has brought (Aguilar, Aziz Barry, Brunet, Ekang, Fernandes, Massoukina, & Zhang, 2009)....

- “In nature there are neither rewards nor punishments – there are consequences.” this quote argues that identifiable consequences of climate change are substantial to understand climatic events (Ingersol, 1899 p.270 cited in Burroughs, 2007). The term ‘climate change’ indicates the statistically long – term period environmental deviation of the global atmosphere including the averages state of the climate or natural climate variability (the Intergovernmental Panel of Climate Chang (IPCC), 2007). During the past historical and recent decades, climate change and the Earth’s responses illustrate that most regions have been changed rapidly in the variability of climate including increasing the av...

- What are the risks of climate change and global warming. Climate change is changing our economy, health and communities in a lot of different ways. Scientists have warned us that if we do not do something soon to stop polluting our planet, the results will likely be disastrous. Climate change affects all of us. Global warming can increase the chances of illness and some cases death because of the extreme heat and heat waves. Some people still don’t believe that global warming is real, but because of a lot of studies, that scientist have conducted, we have proof that is it real and we need to do something about it....

- Many terrestrial and marine species have shifted their geographic ranges to avoid their potential extinction posed by ongoing climate change (IPCC, 2014). Geological records show evidence of range shifts in coral reefs during the last interglacial period when sea-surface temperatures were 0.78 °C warmer than today (Kiessling et al, 2012). Coral bleaching and mortality is often associated with ocean warming as well as ocean acidification. High sea-surface temperatures have been increasingly documented along the coast of Belize, Honduras, and Guatemala (Eakin et al, 2010) and have resulted in frequent bleaching events of the Mesoamerican coral reef....

- It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change.... [tags: Global warming, Climate, Climate change]
