Global warming is becoming a huge problem. The summers are going to keep getting hotter and hotter. The glaciers are melting...more polar bears are dying...it's sad...we have to take action by recycling, using less electricity, and saving our planet...

Hot air does not rise just for being hot. The air at the surface of the Earth is hotter than the air above it but it does not necessarily rise. Less dense air rises. Generally warm air is less dense than cold air but the atmosphere becomes less dense as you get higher just as it becomes colder. The atmosphere forms a balance between temperature and density and altitude so the decrease in temperature with height is countered by the decrease in density which means that the hot air on the surface doesn't rise just because it is hot.

Remember, hot air doesn't rise, less dense air does.

Politically speaking, yes it is BS. Global warming is a natural process that has happened many times before. their is proof of this as well... in most cases we didn't even have polar ice caps. these fluctuations in temp are a result of the distance of the sun and earth, the ocean, and several other facts i cant really remember. If you don't believe me, just go to the national climate data center. We may be contributing to this, but not enough to increase it by hundreds of years, maybe one or two. just consider these periods last about 13000 years, we are at the end of the last ice age.

Incorrect concept. Hot air rises, but this has nothing to do with the earth's position in the solar system. The rising is with respect to the earth, not the sun.

This sounds like a question that only somebody that was high would ask.

The reason hot air rises is because compounds move from hot to cold to equilibrate. So no.
There is no up or down in space. Up and down are relative terms.

there is no up or down outside of the atmosphere in space. think about it? what you consider up and down is basically the distance of an object from the center of the earth. if your at point A, X distance from the center of the earth and something is at point B, X+5 distance from the center of the earth. The object is above you. hot air floats higher than cold air. But this is due to energy and gravity. in space we are outside of the earths gravitational pull. so we float. Hot air will float similarly and drift into space in a fashion that cant be described as up or down because it has no relation with the gravitational pull of earth. Since everything that we call "up" and "down" is relative to the center of the earth than earth itself couldn't possibly move up or down .

tht opposite in this case of global warming

its true tht hot air rises b/c its less dense then cold air but in global warming its trying to rise but its been blocked by the atoms of the greenhouse gases cause earth temerature to rise gradually

To even start considering what things are like in space, you have to get over your Earthbound concepts.

Up and down are simply concepts in relation to your position on Earth.

Stationary is also another earthbound concept that does not apply in space. Every object in the universe moves - there are no stationary objects.

Likewise there is no up or down out there.

no hot air rises through other molocules space is a vacume-no other molecules
