There are 1.65 trillion barrels of proven oil reserves in the world as of 2016.
The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves).
This means that the oil is going to run out in our lifetime

Update: It is infact not true (or just partially true), because it only considers already known oil reserves that can be pumped out with current technology.
There is more oil that can potentially be used as technology and infrastructure advances, so the estimate of 50 years is wrong.

I wish this was true so that there would be a hard limit to within this century, on how much ff related damage we will do.
Unfortunately, they are still finding more, particularly in the north. How much yet-to-be-proven oil still out there is what really should be considered along with technology improvements that increase how much oil can be effectively recovered.
Not to mention the vast reserves known to be in Antarctica.
That treaty is only going to last so long before people start getting desperate and start fighting over it.
Oooh I didn’t think about that… I’ll update the post
The reason for the 50 years of oil, as I heard it explained, is that this is how far ahead the oil companies plan. They look for enough oil to cover the timeframe they plan for. When they have that covered, they don’t look, until they need more. When they need more, they go and find it.
