Unbelievable! I will just clap to people's complete lack of creativity! Please Register or Log in to view the hidden image! 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....? Please Register or Log in to view the hidden image!

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.Please Register or Log in to view the hidden image!
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.
Take them on a walk around the building pointing out the change in plants and watercourses over the past few years. Get creative Please Register or Log in to view the hidden image!
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.
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
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!
Doubling the global cloud coverage for a short time would be enough to cool the atmosphere back down.
http://www.iitap.iastate.edu/gccourse/forcing/forcing_lecture_sec.html 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.
Which it is. This guy is simply trying to out-scientist the scientists. Which is futile. 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?
