I just watch An Inconvenient Truth and I am SCARED!! If we do make the changes we need to, can everything go back to the way it was?

I'm sorry - but I can't believe some of the things you guys are saying!! Can you not SEE the effects of global warming around you? Do you not notice that it's getting hotter every year?, that it is getting harder to breath in the summer? I think you people that don't think this is a real problem need to OPEN YOUR EYES!!

Reversed? Eventually, but it will take many, many years. There will be some effects of global warming in the next 50 years even if we do everything we can reasonably do. It will take that long to get CO2 to start coming back down.
A reasonable goal is to reduce the effects of global warming to a point where we can cope with them without spending huge sums of money and without having lots of people die in poor countries due to damage to their agriculture.
That's doable, but we need to start now and work hard.

There are actually some competing effects going on. The nutation of the earth around it's axis should be causing a slight drop in the average temperature, while the rise in CO2 should cause a rise in temperature. It looks like CO2 is winning. If we ceased all CO2 into the atmosphere, it would take the biological cycles of the planet a while to drive the CO2 currently in the atmosphere back down to pre-industrial levels, but it would eventually return (carbon would become fixed in sea shells as an example, or solidified as wood in forests (assuming forest was allowed to regrow) The real hazard is the rise in sea level flooding coastal areas - it wouldn't take much rise to cover much of Florida as an example. I wouldn't get overly scared about global warming, but I would be concerned about it - we should pursue non-greenhouse gas technologies for power and transportation, such as nuclear power, solar and wind. (I put nuclear first as it is one of the few technologies that can supply base load independent of the time of day, or wind velocity, yet produces no or little greenhouse gases (most nuclear plants have emergency diesel generators that have to be tested periodically - hence CO2)...

If we choose to assume that carbon emissions really are the cause of global warming (which is still very debatable), then there is actually nothing that can be done in your life time. Carbon takes approximately 100 years to react and break down in the atmosphere. So even if all emissions were stopped today the warming would continue and the current rate for another hundred years.
However, this is making the big assumption that carbon is the actual cause.

No. It's really 'convenient brain pollution'. Don't be afraid of anything mentioned in the propaganda flic. Really, everything is going to be fine.
You can't change, alter, stop, reverse, or 'fix' nature. The ONLY thing that can be done is ignore it. In a few months, it will change by itself, anyway. Nature has been doing this since before man ever set foot on earth and will be doing it when we are extinct thousands of years from now.
Relax. It's all natural and is NOTHING to worry about. You've been subjected to the paranoid delusions of quacks and squawkers clucking themselves into a panic, all for nothing.

Studies have shown that the wild claims made in Mr Gore's movie have been greatly exaggerated. No need to be scared. We do have Global climate change but it is nature's way. I am afraid that if we(mankind) try to interfere in what we do not understand (climate) that we that we will trigger the law of unintended consequences and we may start a cascade of really bad events. The old be careful what you ask for.

how far back do you want to go? that's the question. the movie does not show all of the facts. do some research on opposing viewpoints. al gore is trying to score points. if you doubt me, remember this in ten years. it will all be behind us. bunch of nonsense.
