The issue my group and I are discussing about is global warming. Global warming is described as an increase in the earth’s average temperature that is caused by an increase in greenhouse gases such as carbon dioxide and methane. Scientist have labeled humans to be the main cause for global warming. We believe global warming is a problem because it causes the sea level to rise, extinction of animals, and pollution.
Most scientists agree that humans are the main reason for the development of global warming. When humans went through the industrial revolution, we started to find new ways for energy. One type of energy we discovered and use the most is coal. We use coal for almost everything from electricity generation to liquid fuel. Companies …show more content…
In 1896, it was discovered that carbon dioxide played a role in keeping the earth warm by a Swedish chemist called Svante Arrhenius. In 1950’s, a U.S. scientist named Charles Keeling did an experiment by setting up stations at the South Pole and Mauna Los, Hawaii that measured carbon dioxide concentrations and his results showed that the carbon dioxide concentration have steadily rose. By 2007, IPCC was 90 percent sure that humans were the cause of global warming. American scientist, Wallace Smith Broecker, was largely credited for the discovery of global warming because on August 8th, 1975, he first used the term “global warming” on a paper he published in the Science magazine called “Are we on the brink of a pronounced global …show more content…
Present: In the last past century climates have been rising slowly which glaciers have been melting slowly. Now In this present time in the year 2014 ice have melted in Greenland which is causing reindeers and boulder-moving storms. The melting in Greenland is causing the sea level to rise higher and higher. Running away global warming can’t be stopped if it’s developing in all nations, we the nations in the present time, we need realistic options to keep global warming but also we need to find ways to avoid it. Mountains of ice are melting but we don’t need to panic, we the people have a chance to respond and other things that we need to avoid is all lakes, streams, rivers, and oceans cause now they are having a toxic boom which could affect us
