"The first graph tracks the change in sea level since 1993 as observed
by satellites."

I *really* want to understand the technology that lets a satellite
hundreds of miles in the sky detect a 3mm change in average global sea
level between the start and end of the year with an error bar that
grows to only 4mm over a quarter of a century.
