According to a recent FOX News poll, most Americans believe global warming exists and a majority thinks it is a major problem — if not a crisis. Even so, less than half think they personally can do anything about the problem.

The new national poll finds that 77 percent of Americans believe global warming is happening and, of those, more than twice as many think it is caused by human behavior (46 percent) than by normal climate patterns (17 percent). About a third says it is a combination of both (30 percent).

"I am a genuine 'rocket scientist' and am tired of hearing rank amateurs pontificating on what are largely physical effects brought on by the enormous affects on our planet that are a natural consequence of our flight through space on 'Spacecraft Earth.' A peer of mine once put it in words, 'knowing absolutely nothing about it I can speak at length on the subject.' Having said that I shall be brief." — Raymond (Snohomish, WA)

"This planet has existed for 4.2 billion years, right? It spins in space and takes the moon with it, right? It then spins around the sun, right? It has always had volcanoes and earthquakes, right? Humans have been making pollutants in the atmosphere for about 50 years, right? We must be really powerful. Hogwash!" — Arlene (Fresno, CA)

"I think it true because there seems to be a lot of changes in the weather that was not here 15-20 years ago. People have been telling countries if you don't change the way you do things this and that is going to happen and I believe it. One country in Eastern Europe almost wiped out their trees because of acid rain from factories, but they wouldn't listen. I have seen what pollution can to countries from some of them that I have been in and some areas here in America. That has been harmed by it, so global warming is here to stay and we better get on the ball and do something about it before it's too late." — John

"It is just hot air. This is Mother Nature at work. Look back at history and you will see many devastating events." — Sharon (Oregon)

"Like the 'coming ice age' of the early 1970's, global warming is a farce." — Jay

"Yes, there is global warming. While many are alarmed about it, few are willing to undertake any sort of long-term plan to do anything about it. We set time limits on our commitments to any cause these days and, if the problem can't be fixed in a wink like we see on TV, to hell with it. Let someone else worry about it! Fortunately, it won't cause any great harm in our lifetime. Need a change in attitude? Certainly. Will it occur? No, not until oceanfront property is available in Denver." — Phil (Rensselaer, NY)

"Global warming isn't due to human behavior. Think about it: There once used to be an Ice Age (long before humans existed, let alone technology), and eventually the Ice Age passed, the ice melted, and life was able to survive on Earth. Humans weren't around when all of that ice melted, so it obviously isn't due solely to the human lifestyle." — Sara (Pasadena, CA)

"It is all cyclical and frankly there's not a lot we can do about it anyway unless we return to living like cave men. We all know that isn't going to happen." — Michael (Lexington Park, MD)

"I believe the earth is going through a normal warming period, just as it endured an ice age. We have fossils here in Alaska of ferns and other warm climate flora and many fossils of animals that are only found in warm regions, indicating that even Alaska with all its glaciers and permafrost has been tropical at some point. Fear not." — Bobbi (Alaska)
