In today’s world, the only thing that seems to be constant is change. This same concept applies to global warming and agriculture. The average temperature appears to be increasing every which seems to be caused by human activity adding carbon dioxide into the air. With an increase in temperature holding and providing water for farmers in order to water crops will become evermore difficult. With the challenge of global warming set into affect the world will have to better utilize water, carbon dioxide fertilization, global trade, and seed technology.
Causes of Global Warming
Global warming, which is an increase in the average temperature of the earth, has many factors that have to be considered to what is the culprit in an increase in temperature. According to Utah researchers, Eldredge and Biek, the earth is currently in an ice age with temperatures colder than they have been throughout some of earth’s history. Going through cycles of above or below average temperatures is very normal for the earth as many different factors go into the temperature including ocean and atmospheric temperatures, volcanic eruptions, and the level of carbon dioxide in the atmosphere (Eldredge and Biek, 2010). Knowing that the earth goes through cycles of warm and cold weather makes it difficult to have a definitive answer of how much human activities actually contribute to the warming of the earth. With the amount of carbon Dioxide that humans emit into the atmosphere, almost all scientists agree that human activity is having a profound affect on global warming. Stanford researchers Lobell, schlenker, and Roberts present data showing an increase of .13 degrees Celsius every decade since 1950 with an expected increase in temperature per year due to carb...

...technology instilled in the crops will be very important. Finding the proper location for certain varieties to be planted is half the battle in having lucrative yields. Planting C3 crops in cooler climates across the globe while planting C4 crops in warmer plants where they will be the most beneficial is an important step that will have to be made. Also developing different varieties including drought resistance helps combat the ever-changing climate. The conservation of the nutrients in soil will lead to higher yields and can be accomplished with new innovations such as no-till farming. No till farming keeps micronutrients in the ground due to the fact the ground is not worked nearly as hard as if a plow were to go through. Since the soil stays in one place with no-till sub-moisture and nutrients are not lost when the ground is turned over and exposed to sunlight.
Global Warming, much of what does or does not happen forty years from now, rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate, there are other environmental problems; “we now face a global crisis in land use and agriculture that could undermine the health, security, and sustainability of our civilization”. Rather than worry too much about emissions, we should accept the world is going to get warmer anyway and adapt to global warming by building better flood defenses and developing drought-resistant crops. We cannot dispute that automobiles, factories, and power plants, displace an unprecedented twenty tons of carbon monoxide per person per year.
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
Global warming is an issue we are all pretty familiar with. It is the climate change that we, humans, are responsible for. The warming of the earth’s atmosphere is caused by the fossil fuels we burn, clearing of forests, and the carbon dioxide and other harmful gases we release into the air (Cunningham, Cunningham, 2009). There are other harmful toxins we use such as pesticides that are supporting global warming. Some effects of global warming include: increase in weather catastrophes, melting glaciers, rising sea levels, and the impact on species could lead to extinction (Cunningham, Cunningham, 2009). “Many scientists regard anthropogenic global climate change to be the most i...
Climate change has become of the world’s major issue today. The earth’s climate is always changing in a very fast and also in different ways. Climate changes affect our lives psychologically, emotional and also physically. Climate change is defined as a long term change in the earth’s climate, especially a change due to the increase in the average atmospheric temperatures. Due to this change in temperature, a lot of changes has occurred in our environment, these changes include rising sea levels, flooding, melting of polar ice caps, hotter days, colder nights and heat waves. These climate changes plays an important role in shaping our natural ecosystem, our human economics and also the most important, it affects the human race. For
One of the biggest problems facing the world today is global warming. The main reason behind it is the production of carbon dioxide from our cars, factories, power plants and other greenhouse gases, which is having a heating effect on the atmosphere, and this affects our ocean weather and agriculture, thereby dangerous to human life. “In Climate Crisis at the End of Our Fork “Anna Lappe gives her views on how global warming can lead to many problems, what are its probable causes and potential solutions to it. Whereas in “Research and Development on Climate Change and Greenhouse Gases in Support of Climate Smart Livestock Production and a Vibrant Industry” Scholtz discusses the impact of global warming and continued, uncontrolled release of greenhouse gases on the livestock industry and consequently food security as well as
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).
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
One of the biggest issues the world faces today is global warming. As oceans warm up, ice caps and glaciers melt, causing land along coasts to flood. As temperatures shift, animals migrate, making symbiotic relationships out of sync. The effects of global warming are small, but it is estimated that within a hundred years, the earth will be the hottest it has ever been. Throughout history, people have learned that carpooling and recycling will save the world from global warming. Although it helps, recent research found that animal agriculture affects climate change more than fossil fuel emissions. Not only that, but animal agriculture contributes to resource depletion, water scarcity, and world hunger. In order to decrease the rate of global
Throughout the last 650,000 years, the Earth has faced a change in its climate. There is evidence from the change in the Earth’s orbit and the extent of solar energy that it collects. It is because of Global Warming! Specifically, according to the chart below, carbon dioxide has never reached above 300 ppm for the last 650,000 years and currently as of the year 2013, we have exceeded that limit to almost 400 ppm (Evidence for Global Warming). What a drastic change! Another obvious answer that supports global warming is occurring is the increase in sea level, ocean temperatures, and humidity and the decrease in glaciers and snow cover. Temperatures of many bodies of water and air temperatures have increased over the past several decades and the only answer to this is…global warming!
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) purported that climate change has severe consequences for food security in developing countries. There are numerous factors that are solely responsible for this change which are both natural and man-made. Climate change has led to a decrease in quality and quantity of plant produce and livestock because of heat stress, drought and an increase in plant and animal diseases.
Climate change is currently affecting agriculture because it is causing prolonged droughts, violent flooding, sea level to rise, and also health related issues. Droughts and flooding utterly affect agriculture because it damages cultivation since the amount of water applied to crops and farming is fundamental to the...
Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre.
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.
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
Since 1960s both minimum and maximum temperatures have exhibited a rising trend; with minimum increasing by a range of 0.7-2.0 degrees Celsius and maximum by 0.2-1.3 degree Celsius varying by region and season. Notable also is variability of rainfall patterns such as below normal rainfall in the long rains season and more during the short rainfall season, some regions have recorded more intense rainfall and downpours that have resulted to floods and infrastructural impairments. Extinction or near extinction of flora and fauna, changes in flowering and maturity patterns in crops are all attributable to climate change. These changes have had and are expected to have far reaching impacts on the economic sectors of the economy. Some of the expected sectoral impacts are discussed
