Term paper on global warming quotes
Svante Arrhenius was a Swedish scientist that was the first to claim in that fossil fuel combustion may eventually result in enhanced global warming. He proposed a relation between tale of two cities timeline carbon dioxide concentrations and temperature.
He found that the average surface temperature of the earth is about 15 o C because of the infrared absorption capacity of water vapor and carbon dioxide. This is called the natural term paper on global warming quotes effect.
History of the greenhouse effect and global warming
Arrhenius suggested a term paper of the CO global warming concentration would lead to a 5 o C temperature rise. He quotes Thomas Chamberlin calculated that human activities could warm the earth by adding carbon dioxide to the atmosphere. This research was a by-product of research of whether carbon dioxide would explain the causes of the great Global Ages. This was not actually verified until After the discoveries of Arrhenius and Chamberlin the warming quotes was forgotten for a term paper long time.
Scientists warned the US president about global warming 50 years ago today
At that time it was thought than human influences were insignificant compared to natural forces, such as solar activity and ocean circulation. It was also believed that term paper on global warming quotes oceans were such great carbon sinks that they term paper on global warming quotes automatically cancel out our pollution. Water vapor was seen as a much more influential greenhouse gas.
In the 's there were developments in infrared spectroscopy for term paper long-wave radiation. At that time it was proven that increasing the amount of atmospheric carbon dioxide resulted in more absorption of infrared radiation.
It global warming also discovered that water vapor absorbed quotes different types of radiation than carbon dioxide. Gilbert Plass summarized these results in He concluded that term paper on global warming quotes more carbon dioxide to the atmosphere would intercept infrared radiation that is otherwise lost to space, warming the earth.
The argument that the oceans would absorb most carbon dioxide was still intact. However, in the 's evidence was found that carbon dioxide has an atmospheric lifetime of approximately 10 years.

Moreover, it was not yet known what term paper on global warming quotes happen to a carbon dioxide molecule after it would eventually dissolve in the ocean. Perhaps the carbon dioxide more info capacity of oceans was limited, or carbon dioxide could be transferred term paper on global warming quotes to the atmosphere after some time.
Quotes showed that the ocean could never be the complete sink for all atmospheric CO 2. It is thought that only nearly a third of anthropogenic CO 2 is absorbed by oceans. In the late 's and early 's Charles Keeling used the most modern technologies available to produce concentration curves for atmospheric CO 2 in Antarctica and Mauna Loa.

These curves have become one of the major icons of global warming. The curves showed a downward trend of global annual temperature from the 's to the 's. At the same time ocean sediment research showed that there had been no less than 32 cold-warm cycles in the last 2,5 million years, rather than quotes 4. Therefore, fear began to develop that a new ice age might be near.
The media and many scientists ignored scientific data of the 's and 's in favor of global cooling. Research paper outline science fair the 's, term paper on global warming quotes, the global annual mean temperature curve started writing an essays rise.
People began to question the theory of an upcoming new ice age. In term paper on global warming quotes late 's the curve began to increase so steeply that the global warming theory began to win terrain fast. Environmental NGO's Non-Governmental Organizations started to advocate global environmental protection to prevent further global warming.
Global Warming Quotes
The press also gained an interest in global warming. It soon became a hot news topic that was repeated on a global scale. Pictures of smoke stags were put next to pictures of melting ice caps and flood quotes.
A complete media circus evolved that global warming many quotes we are on the edge of a significant climate change that has many negative impacts on our world term paper. Stephen Schneider had first predicted global warming in This made him one of the world's leading global global warming term paper.
In it was finally acknowledged that climate was warmer than any period since This organization tries to predict the impact of the greenhouse term paper on global warming quotes according to existing climate models and literature information.
The Panel consists of more than scientific and technical experts from more click here 60 countries quotes over the world.

The introduction to the report noted:. Pollutants have altered on a global scale the carbon dioxide content of the air and the lead concentrations in ocean waters and human populations.
