HELP!!! CPU and Computer Temp going crazy!!!

As i sit here typing this on my macbook, My CPU and Temperature is maxed out. The only thing that is open is Safari. I don't know why it's doing this. IT's so bad that there is a 5 second delay when i type so if there are any spelling errors in this i apologize, it is very hard to see what i am typing.

Here are some screen shots i took of the CPU activity and temp gauge. Can anyone tell me what is wrong with my Macbook???
