What is the global warming?

What causes global warming?

• what causes global warming? (example: burning fossil fuels, more?) what gasses cause global warming? (example: CO2 emissions) what products emit those gasses? (example: cars) what activities add to global warming? (example: watching tv) how can we prevent and slow down global warming? (example: changing light bulbs) What else should i know?

• Answer:

  if you were to ask ten people on the street if mankind was causing global warming, at least eight out of ten would say yes. After all, Al Gore’s Inconvenient Truth allegedly provides incontrovertible evidence that this is the case. Both presidential candidates are committed to passing economically devastating legislation that will do little to nothing to stop global warming. Contrary to what is heard in the media, however, there is overwhelming evidence that the warming we are experiencing is natural, with maybe a small amount contributed by man’s activities. Nor is there any scientific consensus. 31,000 scientists have signed a petition stating there is "no convincing scientific evidence that human release of carbon dioxide is causing...catastrophic" warming. The debate is still raging within the scientific community. In this DVD, Sovereignty International has put together interviews of respected climate scientists and biologists from numerous sources who explain, step by step, why Al Gore and the global warming alarmists are incorrect. In some cases, blatantly so. www.globalwarmingglobalgovernance.com EDIT - OK don't get stroppy! Carbon Dioxide Emitted from Cars About 33% of U.S carbon dioxide emissions comes from the burning of gasoline in internal-combustion engines of cars and light trucks (minivans, sport utility vehicles, pick-up trucks, and jeeps).US Emissions Inventory 2006 page 8 Vehicles with poor gas mileage contribute the most to global warming. Carbon Dioxide from Buildings Buildings structure account for about 12% of carbon dioxide emissions. Carbon Dioxide from Airplanes The UN's Intergovernmental Panel on Climate Change estimates that aviation causes 3.5 percent of global warming, and that the figure could rise to 15 percent by 2050. Nitrous oxide Another greenhouse gas is Nitrous oxide (N2O), a colourless, non-flammable gas with a sweetish odour, commonly known as "laughing gas", and sometimes used as an anaesthetic. Nitrous oxide is naturally produced by oceans and rainforests. Man-made sources of nitrous oxide include nylon and nitric acid production, the use of fertilisers in agriculture, cars with catalytic converters and the burning of organic matter. Nitrous oxide is broken down in the atmosphere by chemical reactions that involve sunlight. Deforestation After carbon emissions caused by humans, deforestation is the second principle cause of atmospheric carbn dioxide. (NASA Web Site) Deforestation is responsible for 20-25% of all carbon emissions entering the atmosphere, by the burning and cutting of about 34 million acres of trees each year. We are losing millions of acres of rainforests each year, the equivalent in area to the size of Italy. [22] The destroying of tropical forests alone is throwing hundreds of millions of tons of carbon dioxide into the atmosphere each year. We are also losing temperate forests. The temperate forests of the world account for an absorption rate of 2 billion tons of carbon annually. [3] In the temperate forests of Siberia alone, the earth is losing 10 million acres per year.
