Franco Causes Global Warming Franco

What causes global warming? scientist use the termin of the number of activities contributing the global warming by adding excess amount of greenhouse gases to the atmosphere Green house gases such as CO2 equality in the atmosphere and trap heat to the normally excess into our space. Well many greenhouse gases ocurrs naturality and they needed to created the greenhouse effect the keep the earth warming up to suport life Human use of fossil fuels is the mainsource of excess greenhouse gases using electricity from coal-fired power plants or heating at homes using oil or natural gas "wineless" CO2 and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases because because "biur" the trees means less CO2 conversion to O2 during 150 years of the industrial age the atmosphere concentration of CO2 has increase 31% over the same period the level of the atmosphere methane has reasing 151% mostly from agriculture activities such as reasing cattle and growing rise As the concentration of greenhouse gases grows more heat is trap to the atmosphere and less escape back into space This increasing in trap hit wich made hasten species extinction Thanks for watching to learn more visit about.com
