Defining Global Warming

The global warming , also known as climate change, is a phenomenon of increasing concern to the world. As the progress is changing, each of the Earth’s natural features will have short and long term dire consequences.

To put it simply, this is the increasing trend of temperature rise due to the excessive release of carbon dioxide and other gases that act by trapping heat from the atmosphere.

Thus, with each issue is forming a thick layer of gas that traps heat from the sun directing it on the surface. Year after year, human activities that produce these gases increase, driving up the global warming process.

The gases that cause this phenomenon occur when burning fossil fuels in cars, factories, plants, energy, and many more. The little defense of the planet is caused in turn by the loss of forests, agriculture and increasing deforestation.

Global Warming Affects the Climate Cycle

The earth’s capacity to absorb carbon dioxide emissions are at risk, said the Nature Geoscience journal.

The analysis of the bubbles in the Antarctic containing ice samples 610 thousand years ago, showed that the climatic cycle is affected by emissions of gases blamed for global warming.

The research, carried out by experts from the University of Hawaii, provides the first evidence that there is a natural mechanism called feedback, altered by carbon dioxide emissions, said Richard Zeebe, one of the authors.

“These feedbacks operate so slowly, that they help us in terms of climate change we see in the next hundred years. Now, we have the whole system out of balance,” said the scientist.

For 25 years, researchers suspect that there is a mechanism that regulates the Earth’s temperature and carbon dioxide in the atmosphere.

The old high concentrations of this gas came from the volcanoes, but the rain took them to the mountains and was dragged through the hills and ended in marine sediments, said the scientist. Zeebe and his team studied the carbon dioxide trapped in Antarctic ice to determine the concentrations of this gas in various stages and found that the variation corresponded to the Earth’s temperature.

The results were found that when atmospheric levels of carbon dioxide were low, the temperature was cold and the Earth passed through a glacial and interglacial  periods.

Since the Industrial Revolution, with the excessive burning of fossil fuels, concentrations of carbon dioxide in the atmosphere rose to 100 parts per million.

That means that man releases carbon dioxide into the atmosphere 14,000 times faster than natural phenomena.
