If the glaciers melt,it could so devastating,and deadly,a large population will die,and be without food and water!These are some things we have to face,because of global warming,even if global warming is not manmade,we have to face it, anyway.So,do you agree who cares if its manmade or not,we may never know,but what are we going to do?

Should 3rd world nations start controlling their population?
So many people. Not enough land. Not enough fresh water.
india, myanmar, ethiopia, somalia, etc....
Was the earth built to support so many people?

I am doing an investigative report for Tourism, and i decided to do it on global warming, but I need to relate it to the tourism industry. The only thing I can think of is obvious planes and cars emitting fossil fuels. Links to sites on these issues would be greatly appreciated. Also, if you have answered this question on another section of yahoo, please do not answer again. Thanks

Apparently, some scientist guy has come with a way to fight global warming. For Real. A scientist has invented an artificial tree designed to do the job of plants.

But the synthetic tree proposed by Dr Klaus Lackner proposes does not much resemble the leafy variety.

"It looks like a goal post with Venetian blinds," said the Columbia University physicist, referring to his sketch at the annual AAAS meeting in Denver, Colorado.

But the synthetic tree would do the job of a real tree, he said. It would draw carbon dioxide out of the air, as plants do during photosynthesis, but retain the carbon and not release oxygen.

If done to scale, according to Dr Lackner, synthetic trees could help clean up an atmosphere grown heavy with carbon dioxide, the most abundant gas produced by humans and implicated in climate warming.

He predicts that one synthetic tree could remove 90,000 tonnes of CO2 in a year - the emissions equivalent of 15,000 cars.

"You can be a thousand times better than a living tree," he said.

Carbon sinks

For now, the synthetic tree is still a paper idea. But Dr Lackner is serious about developing a working model. His efforts suggest the wide net of ideas cast by scientists as they face the challenge of mitigating climate change.

Dr Lackner believes that carbon sequestration technology must be part of the long-term solution. Global reliance on fossil fuels will not decrease any time soon, he said, and developing countries cannot be expected to wait until alternatives are available.

The technology calls for two things - seizing carbon and then storing it. Direct capture of CO2, from power plants for example, is the simplest, according to Dr Lackner. But this doesn't work for all polluters. A car can't capture and store its carbon dioxide on-board; the storage tank would be too large.

"It's simply a question of weight," he said, "for every 14 grams of gasoline you use, you are going to have 44 grams of CO2."

The alternative is to capture emissions from the wind. In this case, a synthetic tree would act like a filter. An absorbent coating, such as limewater, on its slats or "leaves" would seize carbon dioxide and retain the carbon.

Dr Lackner predicts that the biggest expense would be in recycling the absorber material.

"We have to keep the absorbent surfaces refreshed because they will very rapidly fill up with carbon dioxide," he said. If an alkaline solution such as limewater were used, the resulting coat of limestone would need to be removed.

Dr Lackner is considering other less-alkaline solutions to prevent carbonate precipitation.

"There are a number of engineering issues which need to be worked out," he said.

Home use

A synthetic tree could be planted anywhere. A small one could sit like a TV on the lawn to balance out the CO2 emitted by one person or family.

But more practically, said Dr Lackner, a device the size of a barn would sit in the open air, near repositories for easy transportation and storage of carbon.

He estimated that 250,000 synthetic trees worldwide would be needed to soak up the 22 billion tons of CO2 produced annually.

But not everyone is rooted to the idea. Massachusetts Institute of Technology engineer Howard Herzog thinks Dr Lackner's design won't hold together on the scale he proposes.

He said you would expend more energy in capturing the CO2 - in keeping the slats coated in absorbent and disposing of it - than you'd save.

"Once the solvent captures the CO2, it holds it on tight," said Dr Herzog, "and it's going to take a lot of energy to break those bonds."

He said that much more research is needed on the technology.

"The idea of air capture is seductive and would really be great to have," said Dr Herzog, "but it's important to separate out the concept from the technical details."

'Early days'

Meanwhile, Dr Lackner is pursuing his idea for carbon storage. While he was at the US Department of Energy's Los Alamos National Laboratory, his team worked on a storage method based on a natural chemical process known as rock weathering.

When CO2 binds with magnesium, it creates carbonate rocks which, according to Dr Lackner, retain carbon permanently and safely.

Currently, he said, the process is still too expensive to develop on a large scale.

But Dr Lackner is optimistic that the costs for carbon capture and storage will come down.

"This is still the early days of climate solutions," he said.

The melting of the polar regions has thrown off the balance of the earth. As the glaciers have nearly melted, the weight at the north pole has decreased. This has allowed the heavier, wider portion of the earth at the equator to start slipping downward, thus increasing the tilt significantly.


Why has no one noticed?
It did not slip all at once. It has been a slow change over the past 20 years, but two of the most significant axial shifts occurred between Dec 4 and 6, 2006.

Despite common misperception, an event like this can happen silently rather than a catastrophic sudden change. A 2000 mile shift would not be felt any more than you can feel the rotation of the earth. The earth rotates nearly 25,000 miles every day. About 1038 miles every hour. You cannot feel a 2000 mile change in the axis any more than you can feel the earth rotate or orbit the sun.

Ok so I've done plenty of research to see that Global Warming clearly isn't real, and I'm getting annoyed with people claiming that it is real just because they choose to believe people like Gore who are trying to get money. Anyway if your like me, and agree with me on this, we really get the plus side. Yes we can help the enviroment but at least we who did the research don't have to freak out about the earth getting flooded out so we can just sit back, relax, and watch everybody else freak out. Does anybody side with me on this?

Just curious, if I used an oil-burning lamp to make my way around the home, would it be better than turning on energy-efficient bulbs from room to room? The oil burning lamp would use a fossil fuel and emit CO, but the lights in each room would have the energy use of the "big draw" when you first turn them on. And if energy efficients are better, would nuclear power plants have more or less global impact than coal-burning ones?

With powerful solar (corporation quality) cells and wind-power fitted...

Nobody is working on those as a contingency to help the public...
