7.2.8 (HL)—Fossil fuel dependence

Finite resources have limited stocks, but a reserve estimate is not a fixed run-out date.

Reported reserves change with discoveries, prices, technology, policy and what is economically or socially usable.

A new deep deposit can increase reserves while climate rules make some fuel unusable.

Why can the date move? the estimate and usable stock change.

Finite does not specify one calendar date.
