What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
The paleoclimate record measures at discrete points in time — wherever an ice layer happens to have trapped and preserved bubbles cleanly — rather than continuously, and the temporal resolution degrases with depth as layers compress and diffuse; a single ice sample can represent an averaged interval of years to centuries depending on accumulation rate and depth, a resolution loss with no instrumental equivalent. It cannot measure E(t) or the ocean and land flux terms directly at all; those are inferred from the shape of the concentration curve itself combined with independent proxies for ocean circulation and terrestrial productivity, compounding uncertainty rather than…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
