‘Although there are many effects of global warming, climate change is causing the higher occurrence and spread of disease because of the impact on the population size and range of hosts and pathogens, the length of the transmission season, and the timing and intensity of…
Only very wealthy people could actually own and operate cars. However today almost everyone owns a car. This is because machines produce other machines and thus reduce the costing of building. Thus it can be said that humans live in a much mechanized world today. The machines however need energy to operate. The biggest source of energy for these machines comes from fossil fuels. This is because humans have still not invented a widely usable perfect substitute for non-renewable energy. The energy used has a very bad impact on the environment. The carbon is residue of most combustion process. This is because humans have still not formed a combustion system which could burn with 100 % efficiency. This level of efficiency means that all the fuel I converted to energy. However the current combustion systems give shockingly less amount of efficiency even lower than 50% in many cases. The carbon fuel that does not converted into energy because of this low efficiency level is emitted into the atmosphere. Combined with other harmful products it becomes major contributor to ozone depletion and global warming. Thus not only is it hazardous to health is inhaled in large quantities but it almost causes irreparable damage to our environment.
In definition global warming refers to the increase temperature near the Earth’s surface. According to scientists this process started in the mid-twentieth century and is still going on. The reports recently released by IPCC (Intergovernmental Panel on Climate Control), in the last few years global temperatures have shown an increase of 0.74 ± 0.18 °C (1.33 ± 0.32 °F). Along with burning of fossil fuels as explained above, the deforestation of rain forests is also a major cause of this increase. According to some shocking reports released by the Intergovernmental Panel on Climate Control the temperatures are expected to rise another 1.1 to 6.4 °C (2.0 to 11.5 °F), in the next few decades. ...

The natural system consists of air (atmosphere), water (hydrosphere), rocks (lithosphere) and living things including our selves (biosphere). This essay will focus the atmosphere and biosphere that how the activities of human beings affect the atmosphere and how these activities can be stopped.
It took a lot of time for the scientists to admit that it is result of human activities. There have been continuing changes in the Earth’s climate that has led to the gradual increase in its temperature and ocean warming. “ The term global warming was probably first used in its modern sense on 8 August 1975 in a science paper by Wally Broecker in the journal Science called Are we on the brink of a pronounced global warming?
Though warnings regarding the human produced cause of an accelerated greenhouse effect and the consequential catastrophic outcomes have been voiced for more than a century, global warming has just recently become a significant political discussion, at least in America.
Global warming has become a buzzword in recent environmental discussions. Scientific groups and scientists have been engaged in research and have issued statements concerning global climate change. A widespread opposition to cut down the amount of emission of greenhouse gases has remained oblivious within the field of science.
There are many negative effects that are associated with the occurrence of global warming. The first negative effect is the change of climatic conditions. With global warming, the world will experience extreme weather changes more often that experienced. That is the dry seasons will be more intense and the cold seasons will also be intense.
Presently, it is undergoing a very rapid warming, which is the outcome of human activities like rampant and indiscriminate deforestation and reckless exploitation of natural resources for industrialization. One of the main causes of this rapid warming has been attributed to burning of industrial fuels like coal, oil and natural gas.
An interdisciplinary research in this field is important, because global warming is caused by many factors and has an impact on different spheres of our life. For instance, climate science is aimed to investigate the changes caused by global warming. Geology examines the impact of human activities (drilling) on climate.
These particles change the quantity of energy that is captivated by the atmosphere. According to researcher Claudia Tebaldi of the National Center for Atmospheric Research (NCAR) in Boulder, Colo global warming is: "The big message that will come out is the strength of the attribution of the warming to human activities," (http://www.ucar.edu/news/releases/2009/greenhousecuts .jsp, viewed on 29.04.2009).
Last year, for example, the Caribbean experienced a period of record-breaking hurricanes. Studies of global warming indicate that this may not be an isolated phenomenon.
The term global warming describes increases in the normal temperature of the Earth's atmosphere as well as the temperature in oceans across the world.
The industrial advancement was said to remarkably cause greenhouse effect and global warming. As many establishments for instance are trying to produce offerings, more greenhouse gases like carbon dioxide and methane are directly emitted into the atmosphere. The rising number of vehicles due to industrialization has even led to the increase of greenhouse gases.
