The same people who predicted peak oil are the same people who are predicting global warming?

I wonder are same people who predicted peak oil are the same people who are now predicting global warming? I remember the energy crisis of the 1970's,long line at gas stations,high inflation and we told by the smart America's days in sun are over.But then come sunny Ronald Reagan as President and America's seems so bright,he decontroled the price oil,and after a sharp the price drop palpability,the price of barrel of oil drop to about 10 barrel,of course expert put much gloom market,indeed,stocks like Exxon were down to 30 dollar share with a dividend 3 dollar that 10 percent yield so I told mom to buy some Exxon and she did and also I first thought before recommending the purchase of Exxon,this company mut paid much of it's income to the dividend,but it wasn't case there paid about 25 percent earning in dividend,also I thought this company must have a lot,but wasn't ,indeed,at that time Exxon had no debt.30 then it's spilt a couple time it's now about 100 and it raises it's dividend every year.Best advice I ever got to mom.
Anyway back peak prediction that turn so wrong today the U.S.A is a float in oil and gas some maybe next year we will be net exports of oil,far cry from 1970's and prediction that all was lost.
Now we hear the same certainty from wise,smart people about global warming.Well,if wrong about peak oil maybe they are wrong about global warming.
