  • 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.

  • NASA satellite data from the years 2000 through 2011 show the Earth’s atmosphere is allowing far more heat to be released into space
  • The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.

  • Carbon dioxide and other global warming pollutants are collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up.
  • over the past 50 years the average global temperature has increased at the fastest rate in recorded history

    Carbon Dioxide and other harmful things are piling up in our atmosphere. The bad gases are causing the global warming. Apparently, the temperature could be from 3-9 degrees higher by the end of the century.

  • Electricity production generates the largest share of greenhouse gas emissions.
  • Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes.

  • Greenhouse gas emissions from agriculture come from livestock such as cows, agricultural soils, and rice production.
  • In the United States, since 1990, managed forests and other lands have absorbed more CO2 from the atmosphere than they emit.

    In this section of the EPA greenhouse gas page, it states the different sources of greenhouse gas emissions. I understand now, after reading it, that greenhouse gas emissions come from not just one place. They come primarily from electricity production, however hey also come from transportation (planes, trains, cars and boats), Agriculture (cows, livestock), Land use, even from our own homes!

  • Carbon pollution is the main reason our planet is getting hotter, increasing the chances of weather disasters, drought and flood and hurting our health. There are solutions. For starters, we can cut carbon pollution by reducing our dependence on fossil fuels and increasing our use of clean, renewable energy. And we can implement policies that help us prepare for flooding, drought, storms and other consequences of climate change. But first, we need national leadership that will stop ignoring what the earth and scientists are telling us about climate change -- and instead start ignoring those who continue to deny it is happening.
  • It's time to listen – and take action. There's plenty we can do

    Global warming Global warming affects the temperature of the earths atmosphere making it much much hotter or warmer than it is supposed to be. Global warming is said to be because we are consuming too much oil, producing too much carbon dioxide and doing too much deforestation.we got to stop cutting trees. Global warming is changing the climate that all living things have come to rely upon.While we fight or struggle to figure it all out, the whole planet Earth as we know it-coasts, forests, farms, and snowcapped mountains, rivers, animals and wildlife are in the small line of melting, dying, being killed, being deforested and obviously BEING POLLUTED!!!

  • 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.
