i am in a workshop for global warming .and we have to cover the effects part of GW(effects only on nature). so can somebody suggest any models for this project or any idea's. we have zeroed on a volcanic eruption and white melting wax as glaciers..
thnx ...
 
Maybe you could have a couple of small greenhouses, keep one of them a bit warmer, and supply it with a little extra CO2. See which one grows faster.
 
you could use open flames to show the average global temperatures for each decade since 1900. The bigger the flame, the higher the average temperatures.

If you're allowed to use open flames of course.

Hope this helped.
 
You might consider models or maps of the extent of arctic sea ice in summer.
Here is a source.

The effects are this: recent science is now concerned about global cooling...but not to worry, by July we will be back in global warming unless you live in Argentina.
