Need help refuting this

[dodger501]

I am in an argument with a wingnut at work re climate change.
He says:

"Al Gore’s wealth was a few million when he left office of the VP. Since then he started his carbon trading con job company he is now worth 100’s of millions. Follow the $$$."

I know this is trying to prove a negative, but I need a source to refute this, can anyone help?

1. He's been making money through Apple, etc., and other investments, but he's poured a LOT of it into

his climate talks.

3. His investments in Google and Apple

and the sales from his books have made him very well off. He has donated his Nobel prize and I believe that some if not all speaking engagement fees to the non-profits he's initiated to fight climate change.

Sorry I can't find a link... will continue to look for one tomorrow.
