The Causes for Climatic Changes

According to this Chapter, the cause of these climate changes came from forcing. Forcing is any ongoing process or discrete event that alters the energy of the system. Examples of natural forcings include volcanic eruptions, periodic shifts in the Earths’s orbit and changes in the sun’s

Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).

Climate change is the term used to describe the warming of the average surface temperature on earth. Climate change; often referred to as the general term global warming, is a topic that often inspires fierce debate among those on both sides of the issue. One thing those who are pro and those that are con both agree on is that the temperature on earth has increased over the past century by an average of 1.4 degrees. The big debate on the two sides is if the warming temperatures are caused by human activities and if it is not stopped it will have dire consequences (the pro side) or if it is the result of natural causes and the earth’s surface will find ways to adapt such as crops becoming more heat resistant (the con side).

Climate is sometimes confused with weather, which can lead some people to think that an abnormally cold day can mean that climate change and global warming is a myth. Climate is the weather conditions of an area over an extended period. Climate change is the current warming trend of weather mainly caused by human activities. According to a report written by NASA on global climate change, the main cause of this new human induced, climate change is what’s known as the “greenhouse effect.” The greenhouse effect results when the atmosphere traps gasses, such as carbon dioxide, nitrogen, and methane which causes earth to trap heat (“Global Climate Change”). According to a report by the Washington State Department of Ecology, carbon dioxide and other heat-trapping gasses caused by humans have warmed the earth and are causing many negative

What is climate change? Climate change in its simplest form is usually described as the average weather in a place from year to year. It consists of patterns related to temperature, precipitation, humidity, wind and of course seasons. These patterns play a crucial role in the shaping of natural ecosystems, the human health, the economy and its cultures because they depend on them. Our climate has become so unpredictable due to its fluctuations in temperature. It is rapidly changing with disruptive impacts, and that change is progressing faster than we’ve ever seen before. Though changes vary from place to place entire communities are at risk because individuals are the ones that have to deal with the aftermath of these

CLIMATE CHANGE Climate change is changes in the usual weather patterns within a certain area. This includes how much rain a certain country gets during a year, or a change in temperature over a certain season in another destination. Climate change is not the same as changes in weather, as weather can change in a few hours or minutes, but climate change takes hundreds and millions of years to change. The climate of earth is always changing, the temperature of the earth can change and last millions of years, and then peak or trough for the next few millions of years. There is evidence given by scientists who study these climate changes that claim earths temperature has risen by one degree Fahrenheit in the last one hundred years. One degree Fahrenheit is even less than one degree Celsius, so it may not seem like such a small change could affect the earth, but this small change already has big consequences. CAUSES There are many events and variables that are beyond our control that can cause the earths climate to change, the climate can be impacted by the earths distance from the sun, as we will receive less solar radiation, Or the sun can send less solar radiation to the earth. When volcanoes erupt it can also impact the climate. But the main concern about climate change, is what we as modern day humans are contributing to it. Everything that requires energy, can impact the climate and causes a climate change. Driving cars, buses, motorcycles, boats, jet skis, requires

Sense 1998, the Earth has produced over 2.5 billion atomic bombs worth of heat because of an event that can occur called climate change. Climate change is the change of global or regional climate patterns that usually occur because of the rise of carbon dioxide in the atmosphere. Although many people disagree about climate changes existence it can be proven as a reality when the statistics are shown on how climate change can begin, how climate change is affecting our daily lives, and evidence that proves climate changes existence.

The term climate change is most often used to refer to a change in the in global or regional climate patterns, it became apparent in the mid to late 20th century “that humans have changed earth’s atmosphere in dramatic ways”(Lallania). It is widely believed that the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels are to blame for this increase. By increasing the atmospheric levels of carbon dioxide we have created what is now known as global warming. This is

Global climate change has been a natural and frequent phenomenon since the beginning of life on Earth. However, the central debate concerning climate change is whether or not it is driven by human interaction with the environment’s resources. Carl Sagan said, “extraordinary claims require extraordinary evidence” (Baum, Haqq-Misra, & Karmosky, 2012). Claiming humans are causing global climate change as a result of greenhouse gas (GHG) emissions is definitely extraordinary, but modern research by the Intergovernmental Panel on Climate Change, the National Aeronautics and Space Administration, and independent research facilities have provided substantial evidence.

In the present day and age, a current phenomena with increasing effects on the Earth is climate change. As a result, massive resource shortages, natural disasters, an increased likelihood of epidemics and disease outbreaks, as well as negative impacts on a wide range of socioeconomic factors are expected (Podesta, J., Ogden, P., 2008). These effects have demonstrated and are continually expected to have the strongest impact on the disadvantaged in developing regions, namely, sub-Saharan African countries and South Asia, in the future, despite a majority of the responsibility being credited to developed nations. In fact, between the years of 1850 and 2000, 30 percent of carbon emissions are credited to the United States, 27 percent is credited to countries in the European Union, and 7 percent to China (Macintyre, J., 2009).

When we hear the word "climate change" many things popped into our minds. Many people believe that climate change exists and others believe it is all hysterical hype. Whether you believe it or not climate change is real and it affects everyone around the world. Climate change is defined as a change in the average weather. Climate change is natural, however, in the last few hundred years it has been artificially sped up because of the actions humans take every day. Climate change can be caused by various activities such as anthropogenic and natural causes. Anthropogenic causes are the results of human activities, which includes, chemical fertilizer, deforestation, increase in vehicles, industries and the emission of CO2 etc. On the other hand, natural causes are ocean currents, forest fire, volcanic eruptions etc. When climate change occurs; temperatures can rise and when the temperature rises, many different changes can occur in the atmosphere and climate of the Earth. For example, the outcome can be more floods, droughts, extreme rainfall, and severe heat waves. In addition, oceans are getting warmer and becoming more acidic, glaciers are melting to a great extent, and sea levels are rising. We are also seeing a huge change in the season's length like winter season is getting short and summer season is getting long. In some parts of the world, there is a decrease in the snowfall amounts. The natural disasters that we are facing now a day such as earthquakes, storm, thunder,

Climate change is a major issue that has been gaining political debate over the past few decades. According to Britain’s former Chief Scientific Advisor David King, climate change is “the most severe problem we are facing today—more serious even than the threat of terrorism” (Worldwatch.org). Research shows that the overall temperature of the earth’s atmosphere has been increasing at an alarming rate. This change has not only sparked the rapid melting of polar ice caps, which are subsequently raising sea levels, but it is also believed to be the cause of extreme weather patterns such as heat waves, droughts, and most recently, hurricanes. With the rise of sea levels being coupled with warmer temperatures, ideal conditions are created for hurricanes to not only form, but also greatly intensify. The general understanding many researchers have is that climate change is at least partially caused by human activity. Where the difference in opinions emerge, is how great of an effect humans have on global warming.

With the rising temperatures, serious occurrences like large storms and heat waves among others are expected to happen often, with more strength thanks to human activities that contribute to increased carbon dioxide gasses in the atmosphere. Among the main factors that contribute to these phenomenon’s being witnessed is climate change. Climate change can be said to be the rise of atmospheric temperature brought about by emission of greenhouse gases and the destruction of environment through human activities.

Climate is increasing our global temperature, and we should be aware of the effects of climate change so we are conscious about how to alter our actions to reduce it. Climate is the overall weather pattern over a long period of time. Over the decades, climate has drastically changed. There are several key factors that contribute to how climate works. The atmosphere acts a greenhouse, trapping the carbon dioxide and other greenhouse gasses inside, gradually warming the earth. The clouds in the atmosphere act as a second layer trapping in the heat from water vapor, and blocking the sunlight. The albedo of ice caps and glaciers is high meaning their reflectivity is high, however, with the melting of ice caps, more heat is retained into the ocean rather than reflected off. Ocean currents also play a role in climate change in the sense that the conveyor belt keeps the oceans circulating. In addition, the Milankovitch theory which uses the earth's eccentricity, tilt, and wobble to explain the alternating warm and cool changes.

NASA defines climate change as a change in the usual weather, which is a change seen and felt outside from day to day, of a specific region or city. The Earth’s climate is ever changing because weather can change within a few hours but climate takes hundreds to even a million years to change. The Earth is estimated to be roughly 4.5 billion years old and with each year that goes by, the climate of the Earth changes more and more. Recently, we have been seeing and feeling dramatic changes in the Earth’s climate, especially with Global Warming; Summers are becoming even hotter and we have now experienced 60-degree weather in the month of December. 2016 was recorded as the warming year to date and 2017 was stated as being in the top three. With these changes one, can only wonder why and the answers are pretty clear; human activities, as well as natural causes are huge influencers of climate change and global warming, we just need to take action and try to control the problems before it accumulates to more negative outcomes in the future.
