I'm watching Dateline right now (yeah, so what. I watch the local and national news and sometimes other shows about the news) and they're talking about Global Warming. So what do you guys think of it? Do you even think it's real or not?

Scientists are claiming that Global warming is in the making, and the polar ice caps are melting.

I believe it. It's all this polution, and Greenhouse gasses causing the problem. Pretty soon though, it will hopefully start to decrease. There are companies working on less polution, and Hydrogen transportation. But if they don't pick up the pace, there may be nothing to help anymore.

I agree, Dateline is confirming everyone's suspension. Global Warming is real! I could go on for reasons why it is real.

Just listening to my brother and mom talking about it, makes me think how stupid they are. (I know it's wrong to call my family stupid and such names but the truth is that I hate them. I love them but I can't wait till I'm outa of this house.)

My mom suggested that "don't ya think that global warming is becuased the sun is getting closer to the sun as we go around it?". I instantly came up with several reasons why that is a completely incorrect assumption.

And my brother says, "every time a volcano erupts, it creates twice as much pollution than humans have ever." First off, that may be true but ash is way heavier than CO2 so it falls to the ground and does not stay in the atmosphere to trap heat in it. And two, vocanic eruptions do create a lot of ash but it reflects the sun's rays (learned this is science last year) so it actually will drop the tempature. Mt. St. Helens dropped the global tempature about two degrees but only for a couple days.

Is the climate changing - yes, but then that is what the climate tends to do!

I don't think all of it is because of emissions of greenhouses gases though.

For a start, there was an ice age just 10,000 years ago, blink of an eye in earths history. We are still in the process of coming out of that ice age and there is every possibility that we'll end up in another ice age because no one knows if the ice age cycle has stopped or even exactly what sends the planet into another ice age, though the increasing climate though effects on ocean currents is predicted to potentially lead to this.

I also think massive deforestation is causing much of the problem. Trees and other plants fix carbon removing it from the atmosphere. Fewer of these plants mean less carbon being removed therefore more left in the atmosphere.

Emissions from volcanoes can effect the earth in two ways - warming or cooling. Mount St Helens blew ash more outwards rather than upwards and had a limited effect on the climate and probably did more to increase the climate than reduce it. Other eruptions cause more cooling. One of Krakatoa's eruptions created what was known as a "mini ice age" for several months (and as a result of this cooling crops failed and many people ended up starving to death) and caused cooling with the last eruption because the ash was sent straight upwards and into the stratosphere where it takes a much longer period of time to descend. There has been next to none of these high-powered explosions over the last century to blast this ash high into the atmosphere whereas there are several gentle eruption volcanos going off (Hawaiian islands, Mount Etna). These release little or no ash, but do still release the gas.

Yes, human emissions play some part but I think the earth is influence by more than just that. In the end though, the climate is not going to remain constant (though some people think it should stay constant for some strange reason). It will either get hotter, or cooler and in the past the earths climate was much, much hotter than it is today.

Good analigy Silvershark... I like movies as much as the other guy but for a movie to dictate what I believe... I don't think so. Do research and find out for your self.
As for me, in canada here some its seems to go in cycles, exp. -29 C, -20, -15 and then its -6. Everyone says the winter is getting warmer but before long its -20 C again. This is just in the spot that I live in, other places it's different. I see on the weather network that some places alot farther north sometimes had closer tempators to us.. but the places inbetween had different temps. This did not happen alot but when I seen it I though it weird.

Maybe more research in this is needed I don't realy know all the suff behind it, though cutting down trees can't be good.

Fox: Volcanoes also throw CO2 and other toxins into the air, that is what causes explosive eruptions. the superheated gasses are constantly expanding, and when the magma rises up, the gasses compress, and they eventually push up and erupt through the volcano.

But that does not mean that it causes global warming. I would be more worried about the hole in the ozone layer, because it lets dangerouse levels of radiation into the earths atmosphere.

-But I am no expert ont he topic, so I dont think that my analogy should be taken to heart.

True, all these manufacturing plants and vehicles combined does do much harm to the ozone layer. Even though people know about it, they tend to do little about it.

Do you guys think that Hybrid cars are helping this at all?

I think it's helping, but not enough...NO WHERE NEAR..enough...

There are regulations to reduce the release of the gases that damage the O-Zone, fridge freezers were one of the biggest culprits but all of the modern ones have been changed, as have a lot of aerosols and other sprays. Everything to reduce the O-Zone layer is to do with the way things are made and their contents rather than people as individuals now, unlike global warming which is why you hear about it, because with global warming there are things YOU can do to help.

In fact I think last I heard the hole in the O-Zone was starting to shrink

Global warming will affect everyone everywhere. It already is. And it is something continuing to happen, rather than something that at least for the time being seems to have stabilised and may be reducing.

Hybrid cars aren't readily available either so they are an option for people (apart from those with lots of money) or are too small for peoples uses, need a decent size to store food shopping and for a family of 4 doing a weekly shop a lot of space is needed!

the firts biodesel sports car was made recently, just thought y'all would like to hear some good news.

but hybrid cars are a good idea, they just arnt very effective. My famaly has a SUV because a small car could not do the things that we need to do, like haluing boats, and trailers, which we often have to do.

It's been a while since this post has been active, but whether global warming is real or not, I don't want to live in polluted cities. I must have fresh air, which is why I always love rain storms.
