As the world as a whole continues to struggle with starvation, especially in Africa and parts of Asia, the question at hand is whether or not global climate change is going to shrink the world's population significantly? The answer to this many other questions lies somewhere in between both arguments. There are a couple of main indicators that prove the existence of global climate change. Firstly, global temperature has increased approximately 0.3°C to 0.6°C (Maslin 29) which in effect explains the recent increase in precipitation, since the warmer the ocean temperatures the more precipitation. This relates to agriculture in many important ways.
Climate change is affecting agriculture by interfering with the efficiency of crop production. Agriculture is facing droughts, flooding, sea level elevations, natural disasters, and health hazards for employees. All of these exponents lead to crop failure that creates famines and food prices to rise. On the other side, agriculture is also contributing to climate change through their output of greenhouse gas emissions and carbon footprints. These are caused by the activities that agriculture engages with such as breeding of livestock, ploughing of fields, deforestation, and the use of pesticides and other agrochemicals.
Tropical storms are becoming more deadly, wildfire and droughts are becoming more frequent, and rain storms are increasing in precipitation and frequency. Energy production and transportation is decreasing due to global climate change. As stated in th... ... middle of paper ... ...o, engineers need to focus on the effects and causes of global warming to find solutions to these drastic and fatal problems. If climate change goes unattended for too long it will be too late. Works Cited "Climate Impacts on Agriculture and Food Supply."
Maunder 1992, Kim, nd). It significantly affects the agriculture and climate dependent crop yields (Kim, 2014). Lybbert (2011) mentions that climate change will considerably influence the agricultural tradition, which varies by location of geographical regions. It is not only impacts the agricultural productivity, but also in livestock and biological changes such as flower blooming, planting period, season of harvesting and time shifting for cultivation (Kim, 2014). It degrades the quality of products during the period of time, which impacts the overall social-economic life of the people (Kim, 2014).

(Climate Change Indicators 1-2) Predicted by EPA as one of the greatest environmental challenges the world faces today. The global climate changing and the greenhouse effect are a result of human activity. If not slow down there will be dire consequences to the world. The last several decades, evidence of human influences on climate change has become increas¬ingly abundant and clear. There is indisputable evidence that human activities such as the burning of hydrocarbons are adding to the concen¬trations of greenhouse gases and global climate change.
Climate change is already beginning to affect plants, animals and their role in the ecosystem. Ecosystems are very important as provides habitable conditions. Ecosystems are sensitive to the changes placed upon them whether it is natural or human related. According to Fletcher, “Studies shows that natural decreases in biodiversity are as potentially damaging as the negative impacts resulting from climate change, pollution and other major forms of environmental stress. Because natural stressors are ever present, the growth of negative impacts related to climate change and human population growth could cause increasing damage to ecosystems that are already stressed as a natural condition.” This suggests that natural stressors to global biodiversity will be greater than before as climate change grows.
“Automobiles, heat from homes and businesses, and factories are responsible for about 80% of today's carbon dioxide emissions, 25% of methane emissions, and 20% of the nitrous oxide emissions" (Thinkquest). In the future, it will be hard to produce food. When Global warming really starts causing detrimental problems, we will have droughts and floods rather often, not allowing crops to grow. Another issue is acid rain, which will kill many of the crops as well. Not having enough food will cause major health problems to billions of people.
