hey so u all have been hearing about global warming more and more lately and to tell u the troth it scares the hell out of me and I was wondering what u gies thought about it … Tim
One of my friends dad told me that in like 1923 or something around there scientists said that if we didn’t do anything to change global warming then in twenty years the world would be gone or people would gone or something. But seeing as how twenty years from then would be 1943 and it is 2006, I think they are wrong. But yes the global warming thing does scare me. As does the thought that there might be a huge earthquake in Utah someday. Or that is what the scientists say anyways.
Don’t worry. The democrats control congress now so global warming has probably already stopped.
Very specific details. bravo. 
Yep, it currently hasn’t been as warm since about the 1930’s. But in the 70’s or so eviromentalists were yelling about gloabal cooling.
So figure out what the obvious conclusion is here. Warmest in the 30’s, then cool in the 70’s, then back up to warm again in the 2000’s. Know what that’s called? Fluctuation. If you don’t know what that word means, go look it up.
Global warming (or rather, global warming as idiots like Al Gore preach it) is nonsense.
It is easy to scare young folks. The geezers here can remember scares of nuclear war and nuclear winter. There were regular articles about how many times over the US and USSR could destroy the world (you would think being able to completely destroy the world once would be enough…). Later came theories of global cooling and how the earth might be headed towards another ice age. There was even talk of nonsense like string theory. It all goes to show how little was understood yet was good enough for scare tactics.
How little is understood STILL. I’m sure people believed in global cooling then just as strongly as people believe in global warming now.
The earth will probablly start cooling down again in 20-30 years and then global cooling will be the new thing.
If it is so scary to you then get off your computer, destroy your car and go make up a sign about the bad things of global warning and stand on the side of the highway/stree with it all day.
the earth is getting hotter cause the sun is getting hotter.
duh.
its been seen on other planets near us that they too are getting hotter, even with no human influence on them.
It’s hard to know where to start in this erudite discussion. True, the climate should be entering into a cooling phase, based on our understanding of the glacial-interglacial timing. I don’t remember “environmentalists” yelling about it and I’ve been involved in environmental study or research for more than 30 years. There is not much to holler about when it is part of geology.
As for whether Global Warming is real, even that functional idiot currently serving as our President agrees that it is. He’s just not willing to do anything about it.
A lot of people say its just a simple fluctuation that has been occurring to our earth forever.
I believe them when they say that, cause I have seen the info and the research and a lot of info on the subject.
The thing is, our fluctuations are getting hotter and hotter, and have been increasing for many many years now.
Al Gore has a nice movie out about Global Warming. Its very good. I forgot the name of it, but you should find it out and go watch it.
The Inconvenient Truth
Havn’t seen it yet but I’ll see it soon. But yeah, All this crap we’re pumping into the air isn’t really good for the planet… The ocean is becoming more acidic, The air is dirty, Coral reefs are going away… It goes on and on…
What I didnt like seeing was the pictures of mountain ranges and Glaciers.
The earlier picture where beautiful with snow, and you could actually see the glaciers. The picture of more recent, there was no snow, and the glaciers have melted and in some cases disappeared.
I have seen this happen too. Not too long ago I made two trips, one trip to Glacier Park in Montana, and another trip to Mt. Rainier.
The trip is always held on the same dates, and have been going on for about 20 years now, so we have pictures of each year. I looked at the pictures from back then, then was standing in the exact location of where the picture taken, and it was plain. Melted away.
Also, in areas where the glaciers used to be, we had to hike up to about 7.5k feet to get as high as the Glacier are. They keep melting and retreating higher up the mountain. The hike was still amazing.
Also, the carbondioxide count in our air is pretty daunting.

My comment was a bit tongue in cheek. Hence the slap at string theory.
Despite my comments, I don’t not believe in global warming. But I’m also not in a panic about it. It’s a complicated situation with many variables and effects and influences. It is not something that you can understand with only a high school education, by watching an Al Gore movie, or by staying at a Holiday Inn Express.
Global warming is also a cause du jour. One way to filter out those who believe in global warming because it is hip and those who really believe it will lead to global catastrophe is to ask them if they would support broad use of nuclear power to replace our dependence on oil, gas, and coal for generating electricity. If they won’t support nuclear power as an alternative then they don’t really believe global warming will be the catastrophe they claim it will be.
Plug-in hybrids are one way to reduce emissions. But to be most effective you need the electricity to come from sources that don’t generate greenhouse gases. The only practical way to do that is to rely on nuclear power with green sources like wind power and solar to back it up. But most is going to have to come from nuclear. Trucks (tractor trailer rigs) would also need to clean up their emissions cause they’re a good chunk of vehicle emissions.
But even with that, the available coal, oil, and gas is going to get used. Either by us, Europe, China, or Asia. It’s all eventually going to get burned and the carbon released into the atmosphere. So gotta figure a way to deal with that eventuality. Cleaning up our act in the US won’t necessarily address the problem if other countries just burn the fuel we didn’t.
“Here it comes! Gobal Warming!!! AHH!!! RUN!!”
…
“It’s coming from over there now! Ahhhh!! Quick, run the other way!!”
Well Tasmania has yet to see the global warming effect with it snowing last week right down to the waters edge (something that does not happen even in winter) in summer.
I have not done much research into it myself because with school work i havnt got a chance. I think the theory behind the movie the day after tommorow Holds some ground.
There are new laws within the last couple months in Canada and the US that are designed for exactly that. They are required to use a higher grade of diesel that has a much lower sulphur content, and burns cleaner. Unfortunately for truckers, it’s also considerably more expensive.
Motors are also being built to higher standards.
Nuclear Power may help in the short term (30-40 years) but is not a sustainable solution. Uranium-based light water reactors (by far the most common technology) rely on cheap and plentiful uranium, which we will quickly run out of if we develop this resource to replace a significant amount of carbon-based generation. The alternative is to use plutonium breader reactors, with the associated weapons problems. With either technology, you also have a huge disposal problem, which remains an externality* even in today’s market, and would be many times worse in an expanded market.
