About prevention against global warming

IPCC is the conference which experts at global warming made. In the first meeting, they reported that if we keep on using oil more and expand economy, temperature will rise 4℃ at the end of the 21th century. In the second meeting, they cautioned that if temperature rise over 2℃ or 3℃ , bad influence will happen all over the world. We must stop rising temperature. In the third meeting, they said that if we achieve it, we must decrease the amount of CO2 at least by 2020.


These are messeages that we must prevent against global warming wituout delay. But recently Kanada, America and Ausutralia broke the Kyoto protocol. So Japan must keep on achieving the Kyoto protocol and stop breaking it.


IPCC reported that saving energy about industry and building is the most effective way to decrease CO2. And saving energy is concerned with saving cost, raising the rate of production , so we can save energy confidently. First we must decrease using oil and save energy by developing new tecnology of energy.
