The Enigma of Climate Change
The earths average temperature has risen 1.5 degrees in the last century. Scientists predict that the average temperature will rise and additional 0.5 to 8.6 degrees over the next one hundred years. Even the smallest of changes in the earth’s temperature can equate to large issues for the life on earth. The increase in temperature causes different effects in different areas such as, longer droughts, more ...view middle of the document...
The oceans and glaciers have been effected as well, with the rising temperatures the earths glaciers have been melting and the sea level rising.
Humans have a large role played in the changes in global warming. Human activities over the years have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. The majority of greenhouse gases come from burning fossil fuels to produce energy, although deforestation, industrial processes, and some agricultural practices also emit gases into the atmosphere. Greenhouse gases act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm. This phenomenon is called the greenhouse effect and is natural and necessary to support life on Earth. However, the buildup of greenhouse gases can change Earth's climate and result in dangerous effects to human health and welfare and to ecosystems. The choices we make today will affect the amount of greenhouse gases we put in the atmosphere in the near future and for years to come.
