Everybody these days seems to think they know all about global warming effects on humans. If you ask anyone on the street, they will likely say that emissions from vehicles and factories cause a greenhouse effect, which results in a warming of the earth’s atmosphere. What most people may not realize is that it doesn’t take much of a rise in temperature to cause catastrophic changes in the environment. Scientists have estimated that the total amount of sea ice has decreased by an alarming 30% since 1979. This translates into an enormous amount of water, with no place to go except inland.

Many low lying countries and cities could literally end up under water with a significant rise in sea level. Global warming effects on humans include increased numbers of natural disasters such as extreme weather events. Some of the effects felt directly by the human body as a result of global warming include: heatwaves – these cause illnesses that are heat related, such as heat exhaustion, sun stroke, and death. People who are most susceptible to heat related illness and death are elderly people, the very young and people who are diabetic. Extreme weather events – hurricanes, floods and tornados increase with global warming. With these weather disasters, humans experience emotional and physical trauma, injuries, illnesses and fatality. Some of these happen on very large scales, wreaking havoc for many people in one location, or even several locations.

Poor air quality – this is caused by air becoming stagnant at higher temperatures, and also by poor air circulation. Levels of smog are increased, and smog brings with it increased asthma attacks and lung irritations for all those who breathe it. Illness and death are common results of poor air quality, especially in large cosmopolitan areas where the amounts of emissions is also very high. Plant problems – the rise in temperatures combined with higher carbon dioxide levels allows some very obnoxious plants to grow quicker, produce more pollen and spread more vigorously. The pollen is a very aggravating allergen to many people, causing terrible allergic reactions. The weeds also inhibit plant growth of other desirable plants that could be for human consumption.

Psychological effects – these are a little more difficult to measure and quantify. When there are long lasting heat waves and little relief from the heat, people lose their drive and motivation. Also, when there are extreme weather events, poor air quality or allergy problems from the plants, all these cause an emotional drain.

Essay writing service essay marking service place an order the scientific panel studying climate change stated that the proof of a warming is clear and the human activity has been the major reason for the change. Global warming is the result of warming of earth and sea due to the increased concentration of greenhouse gases.

The main cause of global warming is the human activities which emit greenhouse gas which is known as the greenhouse effect. The greenhouse effect is the process by which absorption and discharge of infrared radiation by gases in the atmosphere warm the earth's atmosphere and surface. The major greenhouse gases are water vapor, carbon dioxide co2 , methane ch4 , and ozone o3 , clouds also affect the radiation balance, but they are composed of liquid water or ice and so are considered separately from water vapor and other gases. According to the intergovernmental panel on climate change, in 2001, the human activity had played an important role in global warming.

The main reason of warming due to human activities is due to the burning of fossils fuels and rapid industrialization. Since the industrial era the amount of greenhouse gases has increased in the atmosphere, leading to increased radioactive radiations produced from carbon dioxide, methane. Fossil fuel burning has produced a noticeable increase in carbon dioxide from human activity over the past years. And the other major reason for increase in global warming is due to land use change, particularly deforestation. However, because of the increasing demand of raw materials for houses and other uses for example wood and paper pulp, industries tend to cut down more trees. Therefore, the enormous change in the rate of temperature is due to the industrial revolution. Some researchers and scientists disagree to the statement that human activities are reason behind the observable fact of global warming, according to william m.

Gray, ldquo natural variations are the cause of periodic global temperature increases and human kind has nothing to do with the temperature changed rdquo. Some researchers believe that main cause of global warming is natural phenomena such as volcanic eruptions, solar cycles and water vapors. But i insist that these natural phenomena's have existed since from the existence of the earth and haven't showed any ill effects from past many decades. These natural phenomena's are affected by human activities which resulted in causing global warming. If human activities had not played contributed the warming would not have been to the extent of harmful results.

However considering natural phenomena a cause for global warming will not be true. According to karl and trenberth, ldquo over the past 50 years, human influences have been the dominant detectable influence on climate change. Rdquo billy a.the activities of humans that put in to global warming are the use of fossil fuels for example coal, oil, and natural gas and the clearing of land. Most of the consumption of fossils fuels occurs in industries, in vehicles and in power plants that supply energy for houses and offices.

The burning of fossil fuels produces carbon dioxide carbon dioxide is a delays the discharge of heat into atmosphere. Deforestation results in more concentration of carbon dioxide, as it reduces the rate of removal of gas from the atmosphere. Land use changes by humans for example clearing land for logging, and agriculture, which also results in carbon dioxide emissions. The decomposition of dead vegetation is also a reason for global warming because vegetation contains carbon which on decomposition or burning is released as carbon dioxide.
