Unbelievable! I will just clap to people's complete lack of creativity! :mad:

I just came out of a class, and we had to decide as a class what topic we want to talk about for a huge 45 minute presentation. The topic? Global warming. WOW! Let's talk about something as boring as hell that we hear on TV over and over again? Do people have any imagination?

Other choices included underage sex, corporate lack of social responsibility and celebrity role models- MUCH MUCH better topics.

So... now I have to fill 45 minutes with a boring presentation on how the world is supposedly getting warmer.

Any help... Pleeeeease....? :(

I support euthanasia now.... :(

OOOOPS! Infractions.... :D

Id scare them all to death,make up some bogus stories that the world is gonna end because of a chain of events caused by using youre electric heater and breathing to much. Though it is a huge debate,kidnap one of those crazy 'the worlds getting warmer cos you all fart to much' scientists and make him express his views. Btw hasnt this 'global warming thing' happened before. Cos the earth never properly orbits the sun,so there will be 'eras' where the earth naturally becomes hotter and vice versa. Cos that what happened with the ice age wasnt it. Anyways im talking crap,so im off.Good luck with youre presentation.;)

I had to do a presentation with a sore throat, I was losing my fucking voice man. Torture. I lost my voice afterwards tho.

This is a group presentation yeh? Make sure you include some videos. Kill some time and stop people from falling asleep. More coming soon if God Wills. Got an assignment to finish off.

Deny global warming.

Take them on a walk around the building pointing out the change in plants and watercourses over the past few years. Get creative :)

Point out that if the atmosphere gets much warmer, that would heat the ocean surfaces, which would produce more evaporation, for more clouds, which would cause the atmosphere to cool back down, a buffer system.

That means more precipitation, but in different patterns, causing erosion and crop failures where it doesn't fall. That water doesn't stay in the atmosphere indefinitely. Also, water vapor is a greenhouse gas.

I don't know much about this.

But that seemed WAY too simple.

The oceans make up 70% of the Earth's surface, constantly evaporating at a higher rate if the atmosphere got much warmer.

Constantly higher rainfall from constantly evaporating at-a-higher-rate ocean surfaces would certainly cool the atmosphere back down.

at the conclusion of the 45 minutes tell everyone the world tempurature increased by 1.5 degrees due to the previous 45 minutes worth of hot air.

No because although u may get slightly more clouds for a while, the water vapour mixing ratio will be very significant and will further increase the greenhouse effect

Yes, and tell them to turn down their heaters.

The moisture would fall out, as more evaporation constantly replaces it in the atmosphere, a conveyor belt, so to speak, of evaporation and rain fall out.

I'm pleased that so many people of your generation realize there's a problem. When I was your age fifty years ago, if a room full of kids had been given that assignment we would have just stared at each other. I was in what you now call A.P. in several classes but they were all science and math and did not deal with controversial topics. If there was an Honor Society member present he or she might have brought up a topic their advisor had brought in, such as capital punishment. We just didn't talk about stuff like communism and racial or religious discrimination in school in those days, and the environmental movement was ten years off.

I suggest you get them thinking more carefully about cause and effect before they accept the party line about how this is all our fault. Let them know that the polar ice caps are also shrinking on Mars, and last time we looked there were no people there to blame it on.

No one ever promised us that the sun would maintain a steady temperature forever!

That's the problem, with increasing temperatures, less moisture will, as you say, fall out!

Doubling the global cloud coverage for a short time would be enough to cool the atmosphere back down.

Found it recently, very informative, lots of pretty charts, graphics and numbers for your presentation, and it's the best scientific analysis of global temperature regulation I've yet had the pleasure of reading.

I don't know much about this.

But that seemed WAY too simple.

Which it is. This guy is simply trying to out-scientist the scientists. Which is futile.

The oceans make up 70% of the Earth's surface, constantly evaporating at a higher rate if the atmosphere got much warmer.

Stop trying to be smarter than the scientists, troll. You will fail.

The overwhelming scientific consensus is that humans are majorly contributing, if not solely contributing, to global warming. Mars is a different story altogether.

What's wrong with my analysis, ath, can you critique cogently, or will you continue to just bitch and moan?

Any help... Pleeeeease....?
Yeah.

In about 4 to 5 Billion years the Sun will be a Red Super Giant, and Earth will be inside it.

Now that's warm! ;)

Let's pass legislation that taxes everyone to the hilt to pay for making the sun not get any bigger than it already is.

It's up to you to creatively expand that to fit a 45-minute time frame.

Think Shaggy-dog (http://en.wikipedia.org/wiki/Shaggy_dog_story) story-like. ;)

Doubling the global cloud coverage for a short time would be enough to cool the atmosphere back down.

No, as the atmosphere gets warmer, it will be able to hold vapour better so less clouds will form. At the start, you will have slightly more clouds but a lot more vapour and so that atmosphere will get warmer. Then after a while u will have increasing amounts of vapour and not increasing (even lessening) amounts of cloud

Take all politcians and store them in a large cave deep underground. That way much of the hot air will be eliminated and they will only keep their problems to themselves deep down.

The overwhelming scientific consensus is that humans are majorly contributing, if not solely contributing, to global warming.Yes, I'm familiar with the Reds' party line. Oops I mean Greens, I keep forgetting that they changed their color.

But I'm also also old enough to remember when these very same people were warning us about global cooling. Things like El Niño keep jumping up and smacking them in the face and forcing them to change their models. They can't predict the weather accurately two days from now, why should we trust them to predict it several decades in advance?

When was the last time a scientist made an accurate long-term prediction? Their track record is no better than the tabloid psychics. Their predictive models are all hypothetical by the basic definition: They have not been tested. They can't even be classified as theories. This branch of science has not been in existence long enough.Mars is a different story altogether.What an interesting point of view. Considering that it shares our sun, even a layman would presume that its story must be very similar to that of our planet.

I'm all ears, if you know the story please share it. I've been very interested in this inconvenient bit of news since it was first announced and I'm still waiting for an explanation. Enough time has passed for it to be reducible to terms that I can understand.

I know we have core samples that go back thousands of years and other ways of estimating the earth's temperature fairly accurately even further back than that. What we don't have are measurements of the sun's energy output going back more than a few years.

I agree that it's reasonable to prepare for a warming trend, and if there's anything we can do to mitigate it, we'd be foolish not to. But saying it's all our fault is just being fashionably negative about Western civilization. Red Party propaganda--dammit I did it again, it's the Green Party now.

Sure. But the topic has been talked about so much that I have lost interest in it. DO you know how many times global warming appear in the front page of the newspapers here? About 3 times a week. 3 FREAKING TIMES A WEEK! It gets kinda boring after a while... :eek:

Yes, indeed...

Minor changes in temperature always happen once in a while...

I think cows are responsible for global warming... and farts (http://www.heptune.com/farts.html)!

Oh man! I am still LMAO at some of these replies!

I have not doubt that man can create quite a difference on this planet. We realy do need to watch what we do.

However, the planet is in a warming phase. We know that it is getting warmer. We know Earth has been MUCH warmer in the past. We know that humanity can make a difference and we would like to know that we are not pushing it past the point of no return.

In the eras of warming that Earth has undergone, it had forests, a richer oxygen atmospear and was a better enviornment in general to keep this warming under control, even reverse the trend. With over 50% of the worlds forests cut down, a noticable drop in oxygen levels and an increase in the other gases and so on and so forth... we can't say with certinty if we are snowballing the warming effect and if the planet will recover when it would have.

Hope that helps.
