I'm sure you've all heard of global warming. Sure, 2.5-10F degrees doesn't seem like a huge change, but it is! I'm doing a project on it and i'm wondering if you have any facts/figures or opinions?

Thanks.

bloody hell.

I believe that global warming happens naturally (things emitt gases, planets get warmer) the problem is that with all the emissions from powerplants, cars, etc the effect is amplified.

To fix this we have to remember that people in the world are generally much more ignorant than others so instead of just proving that global warming exists why don't we just say "hey gas is 3.85 a gallon how bout you run your vehicle on hydrogen." However this won't catch on because there are almost no H fueling stations. It's expensive to switch over even if it does save over time and seeing as how we've already wasted 8 trillion dollars on various foreign policy there is no money left to switch to alternative fuels. Soooo global warming stays until I discover fushion. ^.^

Wow. I can't even watch more than two minutes of it. Who are these "scientists"?

Ha. There wild animals, of course they aren't "nice". Oh, and humans are pretty mean too. And populations have been decreasing, scientific research shows that. But oh wait, you must think that that research is from "environment people" as well. Oh well, I guess no one can believe science anymore because it comes from those scary people who are trying to help the world.

AND you can't let them become too numerous because not only will they hurt people, but they will also become carnivorous when food runs scarce, subsequently running at risk for killing off too many of their young.

people there is alot u can do about global warming....dont u want urkids to see a polar bear.....i luv polar bears i luv all animals and if we keep using gas like we do...and littering..and not caring where our trash goes....we can stop global warming!!!poepl dont ruin our world...help it!!

See what the government school systems teach you.

If they would just leave nature alone and let it go through the natural process, the way it's suppose to be. Then everything would be ok.

oh well, I guess we will all just have to die then...

I never said my ideas were practical. In fact, I've been stressing that they arent'.

i.e. shade growing foods

as a gardener myself, I laugh. Not only do most plants shrivel in the shade, but trees are not very easy to cultivate around with a large machine.

planting in unforested areas

The midwest...

Because ride paddies produce large amounts of methane, a different method of farming rice would have to be developed.

The only problem is that the methane is produced by the swamplike-habitat that rice needs to survive.

And yeah. We can make a dent by changing our farming methods.

The first problem is how much food it takes to feed the world. Food distribution and overpopulation are our main problems, so we'd have to do something about that.

Lower-impact farming methods are also important (i.e. shade growing foods, planting in unforested areas, etc). Because ride paddies produce large amounts of methane, a different method of farming rice would have to be developed.

I'm not suggesting that we have some magical solution to global warming, but we can't ignore it. If anything, we should at least direct more funding towards reseaching climate change.

Reducing emissions is important even if it doesn't put a stop to climate change because, in case you didn't notice, air pollution is unhealthy.

I also keep hearing this "Plant trees!" argument. Well, maybe if we were to plant thousands of hectacres of artifical forest around the globe, it *might* make a difference. Planting a tree in your front yard is a do nothing solution.

We'd need to plant trees in a solid forest over an area the size of the United States to cut the CO2 level significantly.

So yes, I realize that my proposed solutions are impractical.

The bottom line is no one likes it when their ice cream gets too melty too fast...it's heartbreaking.

Oh I know all about the Milancovitch Cycles and thier effect on the current climate system. The geologic record also only shows these periodic ice ages for the past few million years. It is by no means a permanent staple in the Earth history, but rather a recent fluke. A fluke that could easily be thrown off by, say, the introduction of new gasses and land uses during the agricultural revolution. Evidence suggesting the REASON we're overdue is that we altered the atmosphere when we started planting huge rice and wheat fields thousands of years ago.

There's no hard reason why the ice ages started, although there has been speculation that it had something to do with the massive Huckleberry eruption at Yellowstone. But they aren't permanant, and it's very likely that as long as we keep farming, the ice ages are done for. They are by no means "inevitable".

Firstly, what is your evidence that another ice age is unavoidable, and secondly what "emissions" are you talking about. CO2, or things like sulfur dioxide and particulates. I support the reduction of the latter, but the former is another issue.

Reducing emissions will probably do next to nothing because CO2 levels have not been shown to have a signifigant effect on global atmospheric temperatures. No model has ever been accurate.

And the only way that we can change our farming methods to affect global warming might be for a massive global shift towards hydroponics, which is completely ridiculous and impossible.

I also keep hearing this "Plant trees!" argument. Well, maybe if we were to plant thousands of hectacres of artifical forest around the globe, it *might* make a difference. Planting a tree in your front yard is a do nothing solution.

The truth is we have no true idea what is causing this warming trend, or how large the trend actually is. Because of this, we can't come up with any practical or effective solution worth the investment of billions of dollars.

Not true.

We can reduce emissions, plant trees, change our farming methods, and, though global warming cannot be reversed, we can LESSEN the damage that may be caused.
