I love science

These ideas are okay, but global warming is much more than just global warming. Even though it is the largest contributor, greenhouse gasses include nitrous oxide, water vapor, and methane. Also most countries, will not have enough money for these kind of devices. The government will probably keep these information to just our country, and not to rivals like Russia or Canada.

the only problem is that the oceans create water vapour wich is a greenhouse gas so if we want to make a difference we will have to ban oceans!
