what does methane an nitrous oxide do to cause global warming?

Question

I mean like for instance cars give off carbon dioxide but what about those 2

and if you can also CO2 ones other than transport and power plants

thx

Answer 1

Not a darned thing. The only cause of global warming is Nature. It's the same thing that happened 10,000 years ago, at the end of the last Ice Age.

So don't worry about what Al Gore is telling you. He's just making millions of dollars off of this bogus scam.

Answer 2

Methane and nitrous oxide both trap heat in much the same way that carbon dioxide does, by absorbing infrared radiation.

The amount of extra absorption is greatest when the amount of the gas is small. So the effect of methane or nitrous oxide, which are rarer in the atmosphere, is greater than the effect of the same amount of carbon dioxide.

Eventually, methane reacts with oxygen to make carbon dioxide and water, and nitrous oxide gets decomposed to nitrogen and oxygen.

Don't let anyone kid you that the warming happening now is the same as the kind of warming that has happened in the geological past. The speed of warming in the past 50 years, averaged worldwide, is unprecedented.

Answer 3

Methane gas and nitrous oxide are often the waste products of large factories like paper mills. When they rise into our atmosphere, they don't trap heat like carbon dioxide, but they do erode the ozone layer. The ozone is a protective layer of oxygen that reflects some of the Sun's light back into space. It basically keeps our planet cooler. When this is broken down, more heat is absorbed into our atmosphere. There are dangerously large holes in the ozone above Australia and Brazil because of these gases.
