Not just how much or fast

Ice has a gravitational tidal force. Also, changes to miles thick ice sheets affects earths rotation. Both contributing to a change in shape of the oceans.

Yeah, it's kinda cool to think of the earth wobbling 

like a spun coin as it slows down,

with tire weights around the edge that increase the wobble,

and the tire weights simultaneously move,

change size and change density

Never thought of that stuff on such a large scale...

Could this possibly affect continental movement?

And then affect the shift of plates and the possibility of earthquakes?

A fast plate might move 4" / yr.

Humans have been around 100k yrs so about 6 miles.

In another 100k humans will be gone and the plate will have moved about a long day's walk.

Humanity, just a flash in the pan, but effecting biogeochemistry while we're here!

100k years? Humanity as it is currently defined will be all but extinct within 50 years. We are already on the endangered species list.

We are slowly starting to merge with our creations and that transition will only pick up steam. Along with that, we control the ability to manipulate our genetic makeup.

No, either we kill ourselves off completely or we emerge as something entirely new. Post-Humans, Trans-Humans, or whatever you want to call them is our future.

It's the future, but it's theirs, not ours.
And we do have a choice to survive or not,
in part by paying attention to stuff like this.

We all do, from day 1.
I'll surely be gone before any there is any rise that's going to affect me.

Hmm my life insurance policy is to age 120. This seems to becoming common place.

But yeah, I thought you were responding to my post and not the original.

I guess sea level rise affect depends on where you live. If you live on the beach or low lying spots....

I live beachside, but at 15 feet. I've got 30 years left if lucky, maybe a little more.
Maybe I should be more selfish, care only about me.
I don't carry life insurance any more, costs too much and I've saved enough that my wife will be Ok without me.

Both weather and climate are sensitive to small inputs due to feedback loops.

Are those obtained through effects pedals?

I thought that the earth has actually stabilized compared to earlier in history.

Antarctica moving to the bottom of the world has helped to stabilize the earth.

The moon also having reached equilibrium where one face is locked to the earth provides more stabilization than it used to when it spun as well as rotated.

Agree.  It must have been super wobbly 

after whatever happened that knocked the moon off.

Smoother now for sure, but I wonder,

if it weren't for radioisotopic decay heating in the deep earth keeping the wobble going, 

if we wouldn't have a band of island-continents around/near the equator

like the banding around the gas giants.

Think of the circum-global point breaks!

I thought someone here said the ocean was like a glass of water with ice in it.

LOL.
