Question

What are the major causes for global warming?

Answer 1

I think the major reason is because of green house gases...

We put so much of water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halogenated fluorocarbons (HCFCs) , ozone (O3), perfluorinated carbons (PFCs), and hydrofluorocarbons (HFCs) into our atmosphere that those greenhouse gases in our atmosphere suck up the energy from the sun, and instead of the atmosphere releasing the warm heat in space, it goes back down to the earth...

We are making our atmosphere thicker so it gets warmer.

An example of this is Venus' atmosphere.

Answer 2

The need to increase taxes

Answer 3

The reason is us. We, the people living on Earth are polluting it every single second withut knowing! Every minute, cars belch exhaust, fatories spew tonins into the air, land, and water. And we have cleared millions of square miles of forests, rain forests, and plain for making more paper or whatever. It doesn't matter what's it for because it's still the same effect. Clearing those areas meant loss of animals, plants, soil, and oxygen. The loss increased fires, floods, and droughts. We're raising the overall temperature just by creating and making stuff. The main causes is our ignorant mind and selfish behavior.

Answer 4

Greenhouse gases, increased solar output, and variations in the Earth's orbital cycles around the Sun.  See the link below for further details.
