Climate Changes And Agriculture On Our Environment

Climate change is classified by many different events and reactions that are happening. The first is that the earth’s atmosphere is trapping more heat. “The warming of Earth's climate, due mostly to increased trapping of heat by gases in the atmosphere, often is termed the greenhouse effect. Some degree of greenhouse effect is natural and normal” (Lerner 3). Some percent of greenhouse gases are produced naturally but a majority of the gases are being produced by humans. ”Most scientists agree that this warming trend is the result of loading the atmosphere with carbon dioxide and other heat-trapping gases” (Freedman 2). The atmosphere is being loaded with carbon dioxide and other harmful gases and this is making the atmosphere trap more heat. Changes in air temperature is another factor of climate change. “The greenhouse effect has been extremely important to the evolution and survival of life on Earth. A surface temperature of 59°F is sufficient to maintain the Earth’s reservoirs of life-sustaining liquid water, and to impel climatic

Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.

Climate change is a massive issue that is caused by many different things however, the main reason is greenhouse gasses. Greenhouse gasses are gasses, carbon dioxide, methane, and nitrous oxide being the main three (Greenhouse Gases), that allow direct sunlight to reach the surface and

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).

We all see the weather change from day to day and it is just a normal occurrence. Seasons change from warm to cold and we all just go about our business. But what most people don’t see change is the climate. Climate changes over a long period of time and it has shown a warming trend in the past few decades. Many people attribute this warming trend to the alarming rate that humans are burning fossil fuels and pumping Co2 into the atmosphere, however some people think that climate change is merely a myth or that global temperatures have always risen and fallen during Earth’s lifetime.

Climate change has been created by many different factors. Including methane emissions from animals, like livestock. Methane being released into the atmosphere causes a change in the earth’s climate. A change in the earth’s solar activity has also contributed to global temperature change. These changes are called sunspots and they change the earth’s solar radiation levels. This causes short term warming cycles on the planet. Permafrost is frozen ground that is mainly in the northern hemisphere. It releases carbon and methane into the atmosphere when it melts. This accelerates global warming by adding to the concentration of carbon in the atmosphere. Water vapor holds in heat in the atmosphere due to the greenhouse effect. As temperatures rise all of these factors also increase in turn.

Climate change is a change/interruption in our normal weather patterns. It is when it is warm, even though it is winter. Or cold, even though it’s summer. It can also be called “The greenhouse effect.” gases Like CO2 are a big factor of why climate change is a problem. CO2 helps keep heat stuck to the earth, meaning even more hot days,which is a good thing in some places but a very bad thing for others.This is proven by many charts online showing the changes in weather throughout the years.

Change in climate occurs when long-term weather patterns are altered, through both human and natural causes. It involves changes in precipitation, winds, and temperature as an outcome. Causes include the release of carbon dioxide through such activities as burning fossil fuels and deforestation. Human influences on climate have intensified since the Industrial Era. The atmosphere keeps the climate stable. By disrupting the atmospheric balance, the global climate changes.

Climate change has been in the news for years. Earth's average temperature has risen by 1.4°F (0.8 degree Celsius) over the past century, and is projected to rise another 2 to 11.5°F (1.1-6.6 degree Celsius) over the next hundred years. The main cause of climate change is due to the increase of greenhouse gases. Since the beginning of industrial revolution in 1750s, human have released large amount of greenhouse gases mainly carbon dioxide into the atmosphere.

Climate change can be caused by many different things for example, the differences of solar radiations that’s received by the earth, volcanic eruptions, plate tectonics and human activities have also influenced climate change are often talked about as global warming (Jennings, 2011). Scientist have been trying to figure out the past and future climate by making observations and using theoretical models. There is a climate record of earths past and to this day scientists are continuing to add information. The geological evidence is from cores removed from ice that’s been accumulated, stable-isotope, glacial process and other investigations of sediment layers (Jennings, 2011).

Earth’s climate is on a downward spiral, and our agricultural industry is a main cause. Climate change is upon us, and it’s happening faster than scientists predicted over a decade ago (Pollan 872). Most People don’t care about climate change; things have gotten worse than what the models have predicted, despite being what the data predicts the outcome will be. Agriculture is a major part of climate change, and it’s already happening today such as droughts, flooding, erratic weather shifting, and longer growing seasons (Lappé 854). The massive demand on agriculture, and its growth directly contributes to climate change, and our insatiable appetite is to blame. The dilemma with climate change, is that the sum of every little every day choice that we make that affects our environment, because we are 70 percent of the economy that affects the climate (Pollan 872). The only probable solution to our dilemma is to start making better decisions, and to be conscious of our environment. A key decision we could make to

Climate change is the subject of how weather patterns change over decades or longer. Climate change takes place due to natural and human influences. Since the Industrial Revolution (i.e., 1750), humans have contributed to climate change through the emissions of GHGs and aerosols, and through changes in land use, resulting in a rise in global temperatures.1 Increases in global temperatures may have different impacts, such as an increase in storms, floods, droughts, and sea levels, and the decline of ice sheets, sea ice, and glaciers.

Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007)

Climate change otherwise known as global warming has been an ongoing issue for decades. Beginning in the 19th century, climate change has increasingly affected Earth and its atmosphere. Rising levels of carbon dioxide are warming the Earth’s atmosphere, causing rising sea-levels, melting snow and ice, extreme fires and droughts, and intense rainfall and floods. Climate change has and will continue to affect food production, availability of water, and can add to many health risks in humans and animals. In fact, in an article by Justin Gillis titled, “Scientists Warn of Perilous Climate Shift Within Decades, Not Centuries” he focuses on a paper written by a former NASA climate scientist, James E. Hansen, explaining the effects of climate change on Earth today. Although many believe Hansen’s theories in the paper are quite far-fetched, the author mentions, “Despite any reservations they might have about the new paper, virtually all climate scientists agree with Dr. Hansen’s group that society is not moving fast enough to reduce emissions of greenhouse gases, posing grave risks” (Gillis). Gillis validates the fact that climate change has been rapidly expanding throughout Earth and society has not been able to reduce it fast enough. Many negative risks are being posed and will continue to mount if the issue of climate change is not taken seriously. Although climate change negatively affects nearly all aspects of Earth, it poses a big
