Throughout the last 100 years, there has been an increasing concern about the effect of climate change on our earth. Until recently, many scientists believed that climate change would not harm plant life because plants use carbon dioxide (CO2) to develop and with increasing earth’s surface, comes an increase of CO2 gasses. While it is true that climate change is helping certain aspects of crop life, I now believe that crop production is dramatically decreasing, crop prices are increasing, and food scarcity will become prevalent in the next decades to come if humans do not take action against climate change.
In recent years, scientists have discovered that humans are causing climate change, day after day. Human activities such as burning fossil fuels, or chopping down trees are not only harming our air, they are also causing the earth’s temperature to dramatically rise. According to The Proceedings of the National Academy of Sciences of the United States of America, "global mean air surface temperature increased by 0.5 degrees Celsius in the 20th century and is projected to further increase by 1.5 to 4.5 degrees Celsius in this century” (Shaobing, Jianliang, Sheehy, Laza, Visperas, Zhong, Centeno, Khush, & Cassman 9971). With such high rising temperatures comes the rise of greenhouse gases. It is an accepted fact that climate change is natural, but what is not natural is the human-caused effect of greenhouse gases. “The concentration of greenhouse gases in the atmosphere has progressively increased over the last century or so. For example, [CO2] has increased from pre-industrial levels of 280 ppm to 379 ppm” (Craufurd & Wheeler 2529). Raising C02 is weakening our air, our environment, and even our precious lives. With such high t...

The plants we grow for food needs specific resources to thrive, which includes the night temperature and enough water. A changing climate could create a lot of problems. Climate change could make it too hot and also make it too cold to grow crops in some areas of the world and also climate change can cause drought, which is made by the unavailability of water for irrigation. Climate change is likely to cause stronger storms and more floods, which will damage the crops. . Latin America and Southern Asia is seeing it in lethal storms and floods whereas Europeans are experiencing it in melting glaciers, forest fires and disastrous heat waves (Pearce, 2006). Deforestation is another anthropogenic factor that is causing climate change because of the need for fossil fuel, agricultural lands are being used. Forests are being burnt down by humans on a daily basis. As agricultural lands becomes less in need of growing population, people extend their space by cutting and clearing forest. The land beneath the forest sometimes tends to be unproductive and lacks the natural chemicals for a growing. The plantation will serve as a source of food for a few years after then the land becomes useless because of its infertility, it nutrients get depleted and used up. Deforestation results in numerous problems such as destruction of our natural resources, ecosystem, wildlife,
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
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
...depletion of the ozone layer, biodiversity and stress on food producing systems(IPCC 2013). Therefore, climate change is highly risky and the appropriate international steps should be taken in order to stop more climate change and its negative and severe consequences.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).

Thousands of species have become extinct over the last four decades as a result of changes in land use and as a result of global warming. Whether or not the millions of species can adapt and evolve to climate changes is debatable. As this brief overview will report, the human species is not adapting well to the changes. It must be remembered that increases in the levels of carbon dioxide are certainly responsible for the risk many species face, but so is the way land is used, e.g., rain forest destruction. There is a feedback loop wherein plant life and the climate are interdependent. Each affects the other. When forests are cut down, temperatures in that area will rise. Rising temperatures cause other plant life requiring cooler temperatures To die off.
We live in a world where many people either do not know much about the issue of climate change or hold many misconceptions. Climate change skeptics often cite that since the climate has changed in the past, it does not matter that the climate is changing now. Science says that carbon dioxide is the main factor when it comes to what contributes to climate change. It is not necessarily the amount of carbon dioxide in the atmosphere, but rather the rate at which it is changing. There have been periods in history in which carbon dioxide levels have been high, but “Life, ocean chemistry, and atmospheric gasses had millions of years to adjust to those levels” (howardlee, 2014). There have been other times when carbon dioxide levels have changed rapidly, and this has resulted in severe consequences: “When CO2 levels jumped rapidly, the global warming that resulted was highly disruptive and sometimes caused mass extinctions” (Howardlee, 2014). Current data shows that humans are producing this kind of rapid change, and so we must go forward attempting to mitigate large emissions of greenhouse
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.
In many parts of the world, ecosystems’ temperatures begin to rise and fall to extreme levels making it very difficult for animals and plants to adapt in time to survive. Climate has never been stable here on Earth. Climate is an important environmental influence on ecosystems. Climate changes the impacts of climate change, and affects ecosystems in a variety of ways. For instance, warming could force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. Similarly, as sea level rises, saltwater intrusion into a freshwater sys...
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...
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.
Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment.
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”).
