How are cars affecting on global warming?

Question

does anyone know how cars are affecting on global warming?

Answer 1

cars release Carbon dioxide that can increase the risk of global warming

Answer 2

according to a U.N. report released last year, methane  from domestic livestock contributes more to global warming than the emissions from all the cars & trucks in the world.

personally I dont give much credence to U.N. sponsored studies. but its there if you want to look for it.

Answer 3

well cars release CO2 which there is too much of and everything we pretty much do releases Co2 which is causing global warming

Answer 4

Cars emit CO2 (carbon dioxide) as a result of burning fossil fuels.  This excess CO2 in the atmosphere traps heat from the sun in our environment and is one cause of global warming.  Airplanes also add to this by burning fossil fuels, not to mention coal-burning power plants.  They all add to the mix of too much CO2.  Then if you couple that with deforestation (the cutting down of trees), this adds to the problem because trees are one of the major CO2 "sinks" or a place where the excess CO2 can go so it does not cause problems to the atmosphere.

Answer 5

they are not. Check the temp, we are below normal

Answer 6

Cars have no effect on the weather.  And cars produce CO2 and water vapor because environmentalists wanted catalytic converters on all cars.  So the CO 2 is what they wanted and that's what they got.

Answer 7

Cars do Emit Carbon Dioxide but so do other Things. Trees release their Carbon Dioxide when they die, Deforestation creates more Carbon Dioxide as a result. Population, destruction of coral reefs and Pollution also affect Global Warming. Cars aren't the only things that affect global warming but more of a mixture of them all.
