In fact, several scientists estimate that between 15,000 and 30,000 years ago the Earth was covered by large sheets of ice. This period of time was known as the Ice Age. As the temperature of the Earth began to rise 7,000 years ago, the Ice Age came to an end.
The first theory of global warming came in 1824 when French mathematician Jean Baptiste Joseph Fourier discovered that the Earth's temperature was slowly increasing. Fourier argued that the earth's atmosphere traps solar radiation and reflects it back toward the earth.
In the late 19th century Fourier's theory was labeled the "greenhouse effect" when Nobel Laureate Svante Arrhenius coined the term to explain how carbon dioxide traps heat in the Earth's atmosphere.
Today, scientists disagree on the effects of global warming while some deny the phenomena all together. Despite these arguments many historians point out the direct relationship between man and the environment, often referencing the American Dust Bowl of the 1930s, where large scale soil erosion reduced parts of Colorado, Kansas, New Mexico, Oklahoma and Texas to arid deserts. Currently, many governments and corporations are working to reduce fuel emissions and produce "Earth friendly" products such as hybrid cars. Yet, many scientists warn that global warming is an imminent and pressing problem that needs to be addressed before it becomes irreversible. (History of Global Warming, The New York Times, page 1)
I would like to start with three opinions on global warming. “It’s complete nonsense. Global warming is just nonsense. I’m not seeing any destroying of planet Earth, I haven’t been seeing, and I do not think that any wise and intelligent person could say that there is global warming on planet Earth. We can rather suppose if the ocean will be warmer, there will be more snowing in Antarctica and the mass of icebergs will increase.” (VACLAV KLAUS, speech on global warming) This is how Czech president thinks about this topic. His speeches about this topic are very controversial every time he talks about it. Many people have been influenced by him. Every president or head of the country has some effect on people who live in certain country. It is obvious that he is extremely against global warming.
“Some of the scientists, I believe, haven’t they been changing their opinion a little bit on global warming? There’s a lot of differing opinions and before we react I think it’s best to have the full accounting, full understanding of what’s taking place. (GEROGE W. BUSH, presidential debate, Oct. 11, 2000) He probably thinks that there is maybe some kind of global warming, but he wants more evidences about it.
The last example had been told by Tony Blair, ex-prime minister of the United Kingdom. His opinion is different than the two previous ones. “Global warming is too serious for the world any longer to ignore its danger or split into opposing factions on it.” (TONY BLAIR, speech, Sept. 27, 2005)
Global warming exists. How would you want to explain all the big changes of climate in last few years, glacier discharging and other things which have something in common with climate on the Earth? I sharply disagree with my president, that all the global warming is only nonsense. However is difficult to find any pieces of evidence which are warranted. Mostly all of the “facts” are only presumptions. Rising temperatures and melting icebergs are indisputable evidence that the Earth is warming. There is global
warming. It may be just part of nature, but I think we take the biggest share in that is all this happening. One thing for sure global warming is taking its toll on the Earth.
