project update

I thought we did pretty good on our presentation, but we could have done a few things different.
We could of made our hypothesis better and showed more information.

climate changes

I studied Global Dimming and the ozone layer. I found that Global Dimming causes the suns rays to reflect back into space, thus less energy reaches the earth. It hides the power of global warming and causes droughts. The ozone layer is said to be dissapearing. CFC's eat up the ozone and break it into O2 and O1 molecules.
