Hence the outcome presented by researchers mentioned by Longley (2006a) indicates that the resulting transfer of heat into the oceans would cause global sea levels to rise another 4 inches from thermal expansion. (Longley, 2006a)
In the present scenario where global warming is the outcome of extensive fossil fuel emissions, it would be no use to look upon the main causes of global warming. However, still the onus is on the shoulder of human activities that cause global warming. Central consumption patterns have generated such a rapid worldwide deforestation that a majority of the earth's rainforests have gone early in the 21st century. However, the outcome is in the form of uncultivable land as global warming has made 53 percent of the world's land uncultivable, and desertification had encompassed nearly two-fifths of the earth's surface by the end of the 20th century. Oil slicks on the oceans and the rise in sea level triggered by global warming have endangered more than half the world's coastal ecosystems. According to a UN Report, yet 60 percent of the world's population lives within 65 miles of coasts, relying on those habitats for food and economic livelihood.
Among many Governmental efforts to reduce global warming is the committee set up by National Research Council (NRC), which analyzed not only the global warming trend and ratio but also evaluated the extent to which warming in many versatile ways may be hazardous to humans. The committee being consisted of eleven top most researchers and noble prize winners of the U.S after examining concluded that nothing can be done to stop the dilemmatic conditions rising from global warming because of the reason that 21st century human activities are unlike the past centuries when man was not dependant on machines.
Global warming, according to Adler is not a serious threat as predictions for future warming are largely based on computer models that are unable to predict even current temperatures accurately. So, how come the world can rely upon such models that predict dangers of greenhouse in the future Since 1979, the so-called highly accurate satellite measurements taken have remained unsuccessful in finding warming trend. And independent measurements from weather balloons corroborate these readings. So, usually measurement near cities show high temperatures in the global climate. (Adler, 1998)
Today humans are based upon technical operated machines and computer models, due to which it would be a mistake to continue thinking of processes to reduce global warming. Global warming would continue to rise as long as there is a continuous greenhouse gas emission. (1)
Political leaders have always warned of global warming, as the people they led have never bothered about to increase their emissions of greenhouse gases. One very large problem in greenhouse effect refers to the climate
There is no doubt about the growing drastic haphazard caused by the increasing greenhouse gases as predicted by the researchers. Despite the efforts made by the U.S Government in the form of National Science Foundation (NSF) funds or in the form of advanced research conducted by Bush's Government, it seems there is no stoppage to greenhouse gas emissions, as global warming has tremendously increased the sea level…
As stated by scientists that in the last 100 years on the earth, earth's average surface temperature increased by about 0.8 C. This 0.8 C includes the two third portion of last three decades. These unequal changes in the climate affect almost all living things including human, plants, animals.
As Maslin notes, global warming and the consequent climate change ‘is one of the most controversial issues of the 21st century, challenging the very structure of our global society’ (1). It is caused by the huge increase in the volumes of so-called ‘greenhouse gases’ in the Earth’s atmosphere.
Basing their statement on this record they claim that the existence and prevalence of global warming is not convincing. On the other hand, independent analyses by different researchers and scientists reveal that the climate of earth has been showing increasingly warmer trends.
The greenhouse effect theory postulates that the gases and carbon dioxide expelled by people through the burning of fossil fuels, land clearing and agriculture collect in the atmosphere and cause the earth's average temperature to rise. This is known as global warming, which then leads to such ecological aberrations as ozone layer depletion, rising sea levels and changes in the pattern and amount of precipitation.
The author claims that the fact that global warming is a threat to human life is evidenced in the impact it has had, and is likely to continue to have, on human health. Increasing numbers of people are dying as a result of heat waves, they are suffering the consequence of diseases which are spreading because of increased temperatures.
The projected rate of climate change is very alarming to many scientists but not as much to politicians as this topic isn’t as high on the political agenda as some others. It seems that the world leaders have no sense of
The author of the essay comments on the cause of global warming. Namely, it is stated that it is caused by the release of industrial gases through the burning of coal, wood, and oil. As a result, when the atmospheric and sea temperatures rise, this, consequently, leads to the rise of sea levels resulting into irregular rainfall patterns.
The extreme weather conditions and untimely changes in climate were enough evidence that something was wrong somewhere. I did not have to question God to understand the effects of extreme temperatures on the earth atmosphere and oceans. My late grandmother had told me earlier that the extreme temperatures were experienced way back in 19th century.
Deforestation is one cause of increase in CO2 concentration in the atmosphere since trees are the most important absorbers of CO2 and when they are cut down, CO2 increases and thus concentrates the atmosphere. Global warming
