An Analysis of the Topic of Global Warming and the Hazard for the Environment

Global Warming

Global Warming is an extremely controversial and current issue today. One definition of global warming is the increase of Earth's average surface temperature due to greenhouse gases that collect in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Some scientists believe it is due to human activities, while others think it's just part of the Earth's temperature cycle that varies every few millions of years.

Many scientists believe that humans have caused global warming.

The have studies that show many different things have been affected by this human activity. One major argument about global warming is that it is happening due to an over-emittance of these gases and fossil fuels such as natural oil, gasoline, and coal. According to Environmental Protection Agency (EPA) reports, the earth’s temperature has increased by 0.8 degrees Celsius over the past century. More than half of this increase has happened in the last 25 years.

Some scientists did a study where they figured out that the year 2000 to
2009 has been the hottest decade periods of the earth. Additionally, scientists think that global warming has put a tremendous increase of carbon dioxide and methane nitrous into the atmosphere due to polluting substances emitted as a result of industrialization, pollution and, deforestation. Carbon dioxide and other gases have been put into the atmosphere ever since the industrial revolution took place in 1790. In the last 30 years, the average consumption of fossil fuel by United States has been 80%.

Fossil fuels are the most dangerous contributors to global warming, according to some scientists. But if this was true, then people wouldn't be allowed to use these fossil fuels to heat their home, or power their car.

Global warming has effects other than increasing the temperature. Scientists believe that the sea levels have risen about 7 inches in the in the last 100 years, which is more than the previous 2,000 years combined. The rising sea levels due to global warming could threaten the lives of people living along the coastal areas. This would affect people who live on islands and coastlines the most, causing them to have to relocate. If the sea levels really did rise, the world would go into a panic trying to find new homes. Another effect of global warming is that the coral reefs are suffering the worst bleaching with the highest dying record since 1980. The coral reefs are an ecosystem that have one of the most diverse species in the world. If this happens, there would be a loss of biological diversity among species, which is needed on Earth.

Scientists that are in favor of global warming also believe that it is causing the colder areas of the world to become more hot, thereby becoming more vulnerable to diseases. On the other hand, many scientists believe that global warming is a myth. S. Fred Singer is an astrophysicist. He has taken a hard, scientific look at the evidence. In his book, Hot Talk, Cold Science: Global Warming's Unfinished Debate, Dr. Singer explores all of the inaccuracies in historical climate data, the limitations of attempting to model climate on computers, solar variability and its impact on climate, the effects of clouds,
ocean currents, and sea levels on global climate, and lastly, factors that could mitigate any human impacts on world climate. Singer's analysis shows that the pessimistic, and often alarming, global warming scenarios shown in the media have no scientific basis. In fact, he finds that many aspects of any global warming, such as a longer growing season for food and a reduced need to use fossil fuels for heating, would actually have a positive impact on the human race. Singer isn't the only scientist who believes this though. There are 31,000 scientists that reject global warming and have said there is "no convincing evidence" that humans can or will cause global warming.

Global warming is a constantly disputed topic during the 21st century. It is almost impossible to know which side is correct, since there are so many different
opinions and many scientific studies done producing different results. The only way we will find out which scientists were right is in the future!
