Are humans responsible for global warming? - Debate.org - 0 views

  • Humans are incresing polution which is harming our planet by making global warming more usual
  • There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation.
  •  
    This is a opinion that demands that we ARE responsible for global warming.

Global Warming FAQ - What Causes Global Warming? - 0 views

  • Question: What Causes Global Warming?Answer: Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.
  • driving cars, using electricity
  • While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.

    It is a misconception that those  who consider themselves skeptical of the  human contribution to climate change do  not believe that the climate is warming,  and further, that a skeptical point of view  is naïve, dangerous or worse.

Global Warming or Just Hot Air? A Dozen Different Views | LiveScience - 0 views

  • Earth's temperature has increased by about 1 degree Fahrenheit (0.56 degrees Celsius) in the last century. Most of the warming in the last 50 years is attributed to human activities, according to the U.S. Environmental Protection Agency.

Global Warming: News, Facts, Causes & Effects | LiveScience - 0 views

  • Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.
