Yeah, that's what I thought...

I wonder how much we've contributed to sea level rise simply by
pumping sequestered water back into the system.  Probably not a lot,
but probably not trivial either.

Reminds me of that clever Medea Hypothesis, wherein multicellular
life is an aberration and single-cell life tries everything to
destroy it, explaining many of the mass die-offs in geoscale
history. It's funny to think of us as the tricky insurgents that
finally get the job done in the end.

Multicellular life was probably only possible once Earth's
atmosphere oxygenated - and once that had happened the amount of
energy available to life was so much greater that multicellular life
was possibly inevitable.

We increasingly know the ages of the earth, over its whole history,
fairly well.

The abstract says maybe not all but enough.

State of the World 2020 is just a few weeks away, beginning January
7, 2020, after we've recovered from the transition and dusted off
our synapses...
