Abstract:
Climate is inherently variable. Climate changes from place to place and it varies with time. The world now faces one of the complex and important issue it has ever had to deal with: climate change. Climate change today is one of the biggest concerns of human beings on the planet and the effects of climate change are undeniable and it may cause environmental, social, and economic threats to the planet. We already know and easily can highlight several signs of climate change. They are: rising global sea level, widespread melting of snow and ice, rapidly changing ocean and global temperatures, and other signs. So, what are the causes of climate change? Is it natural or do human beings cause it? Well, in both cases we would be right. The climate change can be affected by natural factors, such as solar output, volcanic eruptions, and the Earth’s orbit around the Sun. Also, climate change can be affected by human activities such as, deforestation, burning fossil fuels, causing ozone hole, and building mass destructive weapons and using them on earth that causes a huge radioactivity on earth. Currently, the threat of global climate change does not threaten some nations to the extent of others. Compare the United States with the rest of African countries. We live in prosperity and in much easier time than the rest African countries. Most African countries cannot grow anything on their lands because of climate change. At the end, climate change might affect everyone on
It is well known that politics and religion are two topics to never to be discussed with someone one does not know well. In today’s society, it feels as if this list of topics that are socially deemed inappropriate to discuss seems to be growing, with climate change now being a conservation to avoid. This aversion to discussing climate change appears to stem from the fact that the issue tends to polarize opinions, in which people fall into one of two groups: climate change skeptics and climate change believers. This paper seeks to address and analyze the ways in which climate skeptics speak about and understand climate change as well as how climate scientists understand climate change phenomena. More specifically, this paper focuses on how climate skeptics comprehend the relationships between grasslands, livestock, methane and nutrient cycling and how these interconnected concepts do not lead to the type of climate change that “green urbanities /green politicians/green activists/green elite” predict. The paper will conclude with an evaluation of the two differing positions between climate skeptics and climate scientists, in which I will determine which argument I find to be the most accurate.
Everyone talks about climate change and how the Earth is slowly deteriorating, but no one seems to have specific examples. In Linnea Saukko’s “How to Poison the Earth,” she does use specific examples of what is causing climate change. She uses satire with a hint of sarcasm in her essay. She gives the reader specific examples of how to poison the Earth, but not really wanting to poison the Earth. Gretel Ehrlich writes her essay, “Chronicles of Ice,” a little differently. She uses personal experiences of visiting a glacier and the way that it is falling apart to explain climate change. She uses detailed, sensory description to explain
This report investigates the present day issues climate change is having on Australian agricultural farmers. An overview of how sensitive Australian agricultural farmers are to climatic changes is outlined. The discussion then concentrates more on the risks associated by climate change, main adaptation needs and options, as well as options to help Australian agricultural farmers adapt.
Climate change is defined by the Intergovernmental panel on climate change ( IPCC) as a variation in the mean state of climate persisting for an extended period of time typically decades or longer while the United Nations Framework Convention on Climate Change (UNFCC) defines climate change as a change in the climate which is attributed directly or indirectly to human activities that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
Global climate change has positive and negative effects on marine and terrestrial ecosystems. The cause of global climate change is said to be because carbon dioxide is being emitted through the large scale burning of oil, coal and gas, with an additional contribution coming from clearing of tropical forests and woodlands which results in wildlife life destruction. The carbon dioxide traps heat from the sun in the earth's atmosphere and prevents it from being sent back out into space. The heat that stays trapped in the atmosphere causes the global temperature to increase. Globally, average temperatures are expected to increase between 1.5 to 6.1 degrees Celsius in the next hundred years.
There is widespread agreement in the scientific community that the climate is changing and it has likely received contributions from humans in the form of increased carbon emissions. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change has stated that there is ninety percent certainty that human activity has been the primary cause of temperature rises seen since 1950; if the climate rises by more than two degrees Celsius, scientists predict dire consequences to be faced by humans and the world (McMichael and Lindgren, 2011, p. 402). Changes in climate, no matter how small, bring with it changes in other seemingly unrelated aspects of life. As current research suggests, climate change will have negative effects on
The data of the Table: 4.1 specifies the total respondents into three categories, where 72 percent people in Jessore district and 46 percent people in Mymensingh district were agree about climate change.
Can you imagine a world without the state of Florida? Having a giant hole in Australia? Asian Islands vanished under water? While many people have doubts about the underwater city of Atlantis, we are looking at a world where underwater cities will no longer be objects of wonder and fantasy.
Global warming and climate change will trigger major change in diversity and abundance of arthropods, geographical distribution of insect- pests, insect population dynamics, insect biotypes, and herbivore- plant interaction, activity and abundance of natural enemies and efficacy of crop protection technologies changes in geographical range and insect abundance will increase the extent of crop losses and thus, will have a major bearing on crop production and food security. Distribution of insect- pest will also be influenced by the change in cropping pattern triggered by climate change. Major insect pests such as cereal stem borers (chillo, sesamia and scirpophaga), pod borer (Helicoverpa, Marucaand Spodoptera), aphid and white fly, may more to temperate regions, leading to greater damage in cereals, legumes, vegetables and fruits crops. Host plant resistance, biopesticides, natural enemies and synthetic chemicals are some of the potential options for integrated pest management. However, the relative efficacy of many of these pest control measures is likely to change as a result of global warming. Climate change will also result in increased problems with insect- transmitted diseases. These changes will have major implications for crop protection and food security particularly in developing countries where the need to increase and sustain food production is most urgent. Long term monitoring of population level and insect behavior, particularly in identifiably sensitive
Rainfall and temperature are the main parameters to measure the climate in a region. These two variables were studied in detail for the Arabian Peninsula as well as for Saudi Arabia (Elagib and Mansell, 2000; Lazaro et al., 2001; Moonen et al., 2002; Islam et al., 2010). It is worth mentioning that, the frequencies of rainfall intensity are significantly required for several engineering purposes; one of them is the estimation of extreme floods. Besides, rainfall data can be identified by three parameters; frequency, duration, and either mean intensity or depth. The rainfall event frequency is usually expressed by its return period or recurrence interval. Many researches relevant to climate change and
Have you ever taken a swim in the pool on a hot December day. The odds are probably slim, however if we continue to emit greenhouse gasses into the atmosphere we might see this as a new normal. Global warming and climate change has the potential to be a serious issue in the world today. Global warming is a global temperature rise. With the ice caps melting many animals are going extinct or having to adapt to different places of the world. Leaders of the world are also starting to realize that global warming is starting to lead to climate change.
“If people knew the benefits of nature besides cute animals and a place for them to vacation. If they knew nature provided clean air, fresh water, pollinators for our crops, new medicines, new food crops, and that we can’t afford to produce these things for ourselves… They would understand the full value of nature,”- Harrison Ford. Climate change is a hotly debated topic in our world. There are those who believe humanity is causing the changes we are currently experiencing. Additionally, there are groups disputing the claim, citing research that states the climate goes through cyclic periods of warming and cooling. Several groups have a part in the debate surrounding the causes of climate change, creating further confusion for the general public. There is evidence supporting each side, though at this time there is not enough to make a definitive conclusion. The greenhouse effect is the retaining of solar energy in the atmosphere that heats the planet. This is necessary for life to thrive, though causes issues when unregulated (Issitt and Flynn). While global climate change is the modification of the planet’s temperatures, in recent years the trend has been warming. Humans have been a contributing factor to the current changes in climate, although there are other natural elements to be considered for effective understanding of global warming.
The establishment of the United Nations Framework Convention on Climate Change (UNFCCC) has made efforts to address the effects of climate change. The goal of this convention to facilitate international efforts discuss commitments to mitigation greenhouse gas emissions within industrialized and developing countries through annual COPS. Throughout the years, the UNFCCC has reached many negotiations that have both positive and negative outcomes.
The climatic changes have been an issue of controversies around scientists, politicians, and people in general. Indeed, there are many aspects in which climatic changes and global warming step in, being sources of controversies and disagreements. In this opportunity, the discussion about climatic changes will be divided into two different aspects, the first one involves how scientists think about the main cause of climatic changes while analyzing the question “Are humans responsible for climatic changes? While the second aspect will place the climatic changes into a politician aspect, focusing in one of the 2015 presidential debates where disagreements among candidates took place.
The world we live in is facing many adverse challenges harming its environment. The environment faces destruction such as pollution caused to carbon emissions caused by fossil fuels and greenhouse gasses, waste, and a host of other pollutants caused by various other human activities. With an ever-growing population, consumer demand is higher than ever, and as consumer demand increases, harmful environmental consequences arise. The world is at a current situation where the ecology of the planet is not coping with all the environment destructions and this paper focuses on the pollution caused due to enormous, continuously increasing, consumer demand. This excessive demand for consumer products has created most of the present ecological imbalances. Consumer products go through a multitude of steps that are required for them to turn into the final product we see in our everyday life. This push towards consumerism entails a push to an exponential increase in the practices that lead to the creation of the pollutants that are contributing to global warming in such adverse ways. These shortcomings will become a much bigger issue than most people imagine it to be. The disparities or imbalances have already caused environmental problems in various regions of the world, and much more are expected to follow.
