The Causes Of Climate Change And The Reality Of Climate Change

The rapidly increasing amount of carbon dioxide may be one of the factors that cause climate change. As Hillman states, “Concentrations of carbon dioxide in the atmosphere are increasing, and have done so since the Industrial Revolution.” An atmospheric CO2 concentration, research shows that there is a dramatic increase from 280 parts per million (ppm) in 1750 to 373 ppm in 2002, a rise of the third. Furthermore, the linear chart demonstrated the trend of annual global CO2

The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

Climate change is a threat that has been in existences for years, but appears to be a greater threat to the world currently. According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, there is more than 90 percent certainty that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century” (IPCC, 2007).

The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that

Climate change is a global issue that is under an endless debate for its causes. The increase in the global mean annual surface air temperature in the previous century by 0.75C (IPCC 2007) in coincidence with the excess of the carbon dioxide (CO2) concentrations in the atmosphere from 289 to 353 ppm (Lean et al. 1995) by burning fossil fuels support the human-induced hypothesis of climate change. On the other hand, the protestors of the natural origin of climate change build their argument on the variations of solar radiation and volcanic activities (Rind and Overpeck 1993). Meehl et al. (2005) report that the global warming will continue in this century, even if the greenhouse gasses are stabilized. This reveals that the climate change is

People usually get into a long conversation or avoid the argument in the first place when they talk about Climate Change or Global Warming. In fact, climate change is one of the most debatable subjects in the modern era. In addition, there are different views about this subject. One is from the scientific community prospect, which they believe in this phenomenon. On the other hand, there is the skepticism of the economists and investors, especially who work for large oil and gas corporations and real estates to protect their financial status. Primarily, the phenomenon of climate change represents the rapid increase of the global surface temperature. Climate Change is real because there are

One of the most important and controversial environmental issues in the world today is the continual heating of the Earth’s atmosphere. It is felt that the increase of substantial amount of greenhouse gases being released into the atmosphere is associated with unpredictable climate and heat changes. It is often talked about that the primary reason why the global warming situation is increasing is due to the increase of the amount of greenhouse gases present in the Earth’s atmosphere, primarily the amount of carbon dioxide emissions. The increased carbon dioxide amount in the atmosphere that causes global warming is a cause of concern for many people because of its potential dangerous effects to the Earth and the environment. However,

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

Climate change has become a significant policy issue debated by the entire global community. Through out earth’s existence, climate change has been a part of the evolutionary process. Earth’s climate goes through a sequence of glacier and inter-glacier periods. These are periods where the earth heats up and global warming takes over the land. Then, there will be a period of an ice age, where snow and ice encompass most of the land. Recent studies provide evidence to this theory and additionally show that the world is in a current warming period.

In the 1960s, the warming effect of carbon dioxide gas became increasingly convincing. Scientific opinion favoured the warming viewpoint ever more during the next decade. And by 1990s, improved computer models and observational work confirmed that greenhouse gases were deeply involved in most climate changes and human-caused emissions were creating evident global warming (“A Brief History of Climate Change”).

As the global warming debate rages on, some facts about GHGs concentration stand out. According to Etheridge D.M. et.al (1998) the current concentration has been as a result of general increase of 49.4 ppm of CO2 from 284.3 ppm in 1832. As Blasing (2013) observed the increase is attributed to Industrial Revolution – an era when heavy reliance of fossil fuels led to more addition of carbon dioxide and other minor gases in the atmosphere. When burned these sources of energy release CO2 to the atmosphere. CO2 and other GHG gases trap heat and thus causing a greenhouse effect. Although clouds and water contribute about 36-72% of the greenhouse effect, CO2 and N2O are of particular interest since the two gases retain heat for much longer. The atmospheric lifetime of CO2 and N2O are

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

fact that global warming is real and why climate change will never be argued against. 2016 was

In 2007, the Arctic reached a 30-year low for sea ice (University of Colorado at Boulder), because of global warming or what scientists refer to climate change. Global warming might be the greatest threat to the future of humanity. Prevention of a global climate shift depends on early detection of human-made effects on climate. The current debate on global warming is divided into three categories: those who do not believe that the Earth is undergoing a climate change, others that believe the Earth is going through a climate change due to humans, and some who believe that Earth is going through a climate change but is not because of human activities. In order to understand the issues we have to look to scientific data meticulously.
