What is the heck is this "greenhouse effect" I keep hearing about?

Question

I reckon we should start planting some taters and yams if you ask me.

Answer 1

The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface.

Answer 2

In a nutshell, all the smoke and gas is building up making the atmosphere absorb the heat from the sun but not relase it, so just like a greenhouse, it lets the heat in and keeps it warm, so if the world keeps up this pollution we will end up with floods resulting from melting icebergs, among other things..thats all I know..
I did start planting raddish around my house, it doesnt change much, but it sure makes a darn good fattoush salad!

Answer 3

All I know is that let's say, you have a backyard full of plants, during sunny season, the plants has a cooling effect and give you more oxygen that help you feel in good normal condition. And during rainy season, the plants are the ones that help absorb the water so as no flood will occur. Well, something like that.
