Two somewhat independent issues, with the common causality of climate change.

Atmospheric moisture comes primarily from the oceans. A great deal precipitation occurs over land. Therefore, high rates of precipitation should lower the levels of the oceans. Isn't that a win? Rising sea levels are the worst thing ever, right?

Ya tug... On that reasoning, with 70% of the earth's surface covered by water, it would be interesting to see where, on land, the 6" drop in sea level will occur. I guess we'll have to wait and find out.

When you grow the same crop on a field year in and year out in a field eventually the field starts losing productivity and becomes unhealthy.

Change is necessary. Ecosystems need to get mixed up every once in a while to thrive.

Example, San Francisco is an old and dirty city with deteriorating infrastructure. Is it best to keep bandaging? Or, let it become artificial reef and build a new SF 34 feet higher with the latest energy efficient buildings and loads of public transit?

What they have done in past is to overdose it with fertilizer... using it year after year.

Yes, overdosing with fertilizer extended the viability of the field. However, it takes change to keep the field healthy.

Think about beaches. They're sandy, all of the nutrients have been washed away. Sea level rise exposes new land to the ocean to help bring new nutrients into the cycle. Rise is a good thing.

Sea level decline might be an issue though. Imagine all of that salty, briney mud being exposed. Lots of rot and methane production from that. Low tide stinks.

predicted change in this century

Most of the sea level rise is predicted to be in the Arctic, most of the fall is around the Antarctic. This stuff is so easy to find out it just makes people who can't be bothered to look seem deliberately ignorant

Actual change so far since 1993

either way San Francisco seems safe.

Am I reading that right? A metre of rise around much of Australia since 1993? I doubt it.

Yeah, I don't think the scale in the second graph is in meters. I would guess inches. Could be centimeters.

Sorry, the caption didn't link

Regional sea level trends in millimeters per year from 1993 through mid-2018 with the global average rate removed. Red colors indicate that the local rate of sea level rise was greater than average, and blue colors indicate the opposite. Credit: PNAS.

Not quite as useful as this one, which doesn't remove the average rate.

So, in the Australian parlance, ‘bugger all’.

‘Bugger all’ means hardly any. ‘Bugger’ is what you should say when you are shown to be completely wrong.

Canada's greenhouse gas continues to rise

on a positive note for generation of electricity it has dropped considerably... good for EV.

Hokie... yup, we knew that.

Natural changes. Humans must adapt, again and again.
