That is truly naive.
Why did he have ANY holdings in energy companies when he has preached the climate change crap for decades? He led the charge as SOS in 2016 to get into the Paris Climate Agreement. Does that sound consistent to remain in holdings of evil oil and gas companies afterwards as he preached doom and gloom?
He sold off his energy holdings because he MADE MONEY ON THEM when he pronounced statements such as recently saying the earth has only 9 years left if we stay on our path of using oil and gas.
Why did Al gore have stock in Lead mines, petroleum companies, etc? Because it made him (and his family) money.
These people are running under the "rules for thee, but not for me" protocol, and anything they do is for their benefit, Devil take the hindmost.
It's jut more of the usual hypocrisy.
