Causes of global warming














There are many causes of global warming. I will mention some of these causes, then I will examine on of them in details.

1- Carbon dioxide from power plants.
2- Carbon dioxide emitted fro cars.
3- Carbon dioxide from trucks.
4- Methane.
5- Nitrous oxide.
6- Carbon in atmosphere and ocean.

While most know that dioxide creats greenhouse gas. Methane comes second important. back to the IPPC , methane is twenty times more as effective as CO2 in controling
heat in the atmosphere. Levels of metane in the air have sored 145 %. In the last 100 years. Inaddition, methane comes from some types of sources like, rice fields, dirty streams, and from the intial fuel production. The rice in countries that produce is grown in flooded fields and that develop and that cause the damage in the soil, releasing CH4 to the air, launching, through the rice fields.
