What is are the causes of global warming?

Question

what websities can i get info on global warming?

can someone explain to me how global warming was caused?

Answer 1

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.  It's like putting a blanket on the Earth.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood movie style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Really good website for more information here:

Lots of numerical scientific data proving it real here:

Proof that most scientists think it's real and mostly caused by us here:

Answer 2

look at these websites, they might help!

Answer 3

There are tiny little fleas with wigs on that emit powder from these wigs, which cause the wigs to catch fire and warm the air of the earth. The hatching of these fleas is stimulated by human flatulence.

Answer 4

The sun is putting out more energy warming the Earth and all the other planets.

Answer 5

Global warming is caused by the increase of greenhouse gases (methane, CO2, ect) in the atmosphere, thus causing the greenhouse effect to increase, making the Earth warmer by the day. It has been happening since the Earth started, but increase rates are due to the burning of fossil fuel in the last 2 centuries.

My sources are good sites.

Answer 6

people not thinking & cutting down the trees. men & women of the earth.

Answer 7

the sun is the main cause of global warming --- this is why the other planets are warming up too!!!
