How can I conduct an experiment to show the possibility of stopping global warming?

First you have to define what causes global warming.  then you need to decide what of these variable are dependant or independant.  You could then chose one of the independend variables and try to design an experiment that shows how varying that variable causes a change in warming.  an example might be saying that CO2 causes global warming by increasing the insulating value of the atmosphere, you could then set up an experiment where an environment(a large sealed environment(5 gallon glass jug)  is set up to permit differnet concentrations of CO2.  Add a radiating heat source like a heat lamp and heat the closed environment,  measure the inside of the environment and then turn off the light.  graph how long it takes for the environment to return to ambiant tempeture.  increase the CO2 concentration and try it again.   It might be too difficult, but it shows the scientific process.  and you should get some good graph points.

Global warming is happening, 100%, there is no evidence the other way.  The only poblem with the data is the lack of data, we need more of it, more research.\n\nTell your teacher this:\n\nCO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.\n\nLook at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.\n(see links below)\n\nHow's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.\n\nThere has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.\n\nYes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up. \n\nJust to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.\n\nHI CO2: \nhttp://news.bbc.co.uk/1/hi/sci/tech/4467420.stm\nHOCKEY STICK: \nhttp://news.bbc.co.uk/1/hi/sci/tech/5109188.stm\nGeneral climate stuff: \nhttp://news.bbc.co.uk/1/hi/sci/tech/3897061.stm

No it cannot be stopped.....at all. First of all it is a naturally occurring process and humans have actually just accelerated the process. Now as the polar caps melt they release natural carbons into the atmosphere which at the current rate is actually more substantial than all of the carbons mankind release every day and since we cannot stop the ice from melting there is no way to stop the current trend even if we reverted back to the 1800's.

Sorry I'm the kind of teacher you parents despair of because thats the kind of home work I'd set.  My class have to design and make a thermal insulator to stop ice melting this week!!!\n\nTry this link it might help\nhttp://www.volcanolive.com/model.html

Here's some ideas\n\n(1)\nMeasure the hardness and ion content of your local water supply.  You can perform precipitation experiments, measure solid residue after evaporation, and more.\n\n(2)\nSeparate the protein solids and fat from milk.  I think you can do this by adding salt to the milk.  (I've never done it, may be too easy.)\n\n(3)\nDo a project on the danger of confined spaces.  There is a really cool visual experiment that goes along with this.  If you mix vinegar and baking soda in a tall glass you will get a glass full of carbon dioxide.  Since the carbon dioxide is heavier than air, it will stay in the glass for a while (invisibly so).  You can then make a "pouring action" and pour the CO2 into a second glass, although there is no visible flow of gas.  You also need a 3rd glass that has a small, lit candle at the bottom of the glass.  You then make the same pouring action with the second glass into the third and when the CO2 displaces the oxygen and nitrogen in the third glass the candle will get snuffed out.  You can even do this experiment at home for fun!\n\n(4)\nMeasure the pH of common household materials: foods, cleaners, etc.

Search at these sites.  It can be done, but it is usually not economical.\n\nhttp://www.scirus.com/srsapp/\n\nhttp://www.scienceresearch.com/search/

Here are some experiments.

What you want to do is best done by a science called Dendrochronology:\n \nology: the study of \nchronos: time, or more specifically events in past time \ndendros: using trees, or more specifically the growth rings of trees \n\nApplications in dendrochronology include: \necology: insect outbreaks, forest stand structure, past fires\nclimatology: past droughts or cold periods \ngeology: past earthquakes, volcanic eruptions \nanthropology: past construction, habitation, and abandonment of societies\n\nGo to the site in the url and you can learn a lot of real information, not media hype about global warming.\n\nPS. The thermometer was only invented a few hundred years ago. No record of temperatures older than that exists. But old wood lasts for thousands of years and is a true account of local conditions. \n\nEnjoy! It is a fascinating science.

do something on alternative energy or fuel sources. or hybrid machines.

One might suggest reducing carbon dioxide emissions into the atmosphere, but this is only one aspect of the problem.  \n\nWhen carbon dioxide is released, usually from sources of combustion, other chemicals and particulates are also released.  So, curbing the release of carbon dioxide from these sources would also curb the release of these otehr chemicals and particulates.   A recent study has concluded that since we have worked at cleaning up emissions and reducing particulate releases, more sunlight is reaching the surface of the earth and actually _accelerates_ the process of global warming.\n\nHonestly, the best all of us could reasonably do is to be mindful of our energy consumption habits and try to not be wasteful in what we consume and dispose of.  In conjuction with this, look at adding foliage in areas that have been stripped of plant life.  More plants will effectively remove more carbon dioxide from the lower atmosphere.

World-wide reductions of CO2 and CO emissions are the only hope of stopping it. IF we do not do a great amount of reduction within the next 10 years, it will be too late to stop the warming. We can expect the ice caps to melt, leading eventually to an ice age...seems odd, I know, but a fast warming will lead to massive storms that will suck down the upper atmoshpere...see the movie, "Day After Tomorrow." Not really sci fi...can, and well may happen.

try something that deals with solar power. it'll show him that there's alternative fuel sources out there. maybe one day he'll become leader of the world by creating something great. hmm... when i was his age, all i did was cut a tree and reported that you can tell how old the tree was by counting the rings. now i'm a nobody.

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask.  It is done by using the principles of the kinetic theory of matter.  \nAnother cool project might be doing something with dry ice.  Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions.  Make some dye molecules or something.\n\nHope one of these ideas works for you.

Burn the paper and mix the carbon leftovers with the water. You should get some killer jailhouse results.

I would suggest the rock cycle. This is a basic earth science project that you can make as simple or complex as you want. You can identify the three major parts and how they interact going from one part of the cycle to another. You can identify the different properties of these rocks (and find samples if you want). If you want to make it really elaborate, you can bring in how plate tectonics drives the rock cycle, and how volcanism, metamorphism, and sedimentation form the Earth's surfaces.\n\nAnother topic that might be interesting to you would be to identify all the products and materials around you that come from rocks and minerals. Since this includes almost everything (e.g gypsum wallboard, clay in ceramics, iron in cars, aluminum in beverage containers and cars, plastic made from oil, shampoo made from oil, household detergent made from oil, electricity made from burning coal and natural gas, salt on your table, etc). You could look for the most surprising things, and could perhaps include how soil is made from weathered rock so even trees and plants come from rocks. You can do some research on how each of these materials is mined and where it comes from. You get the idea, right? \n\nDepending on where you live, you might do something on natural hazards in your area.If you have earthquakes you could find a fault map for your area and research earthquake hazards. If you have landslides or coastal erosion you could research what causes these things. Of course, if you live next to a volcano that is an excellent topic.  For example, see if you can find an eruption hazard map.  You might want to make sure your teacher approved of this because it might not be within the scope of your class (some teachers might consider this geography more than earth science). \n\nJust a bunch of ideas from a geologist. Hope this helps.

Here is a Malaysian site that will get you started.\n\nhttp://www.kjc.gov.my/english/education/climate/climate01.html\n\nREMEMBER - use the information that is available on the websites as a starting point for your project. \n\nDon't resort to wholesale copying of the content - if you do that the following will happen: \n\n- your own intellectual abilities will not develop to their fullest.\n- even if you win the prize promised to you by your father, you will not gain complete satisfaction, becuase deep down inside you know that you have cheated.\n- you will accumulate bad karma (see the case of poor Kaavya Vishwanathan!!!!!!!!)  \n\nGOOD LUCK with your report.
