It’s hard to get excited about 2.2mm.

I’m not saying it isn’t a problem, I’m just saying it’s not a scale humans are likely to panic about.

If it were 2.2m in one month you can bet your left shoe we’d panic.

Well, it's global sea level. It's pretty significant and just shows how fast the sea level could change if larger chunks of ice would slip into the water and melt.

If it's exponential growth, then that's pretty scary.

If all of the world's ice were to melt the oceans would rise by only 70 meters.

Warmist National Geographic offers that it would take 5000 years for all of the world's ice to melt.

"Only" 70m.

The sea raises and lowers by up to 16000mm every day in parts in of Canada during spring tides

That would be over 600 meters, impressive :p. EDIT: the parent author corrected his entry to still impressive 16 meters.

And of course tides/sea level is almost the same duality as weather/climate.

Up to 16 meters.

Edited to 16000. No idea what I was typing!

16000mm is 16m. Still impressive.

> And of course tides/sea level is almost the same duality as weather/climate.

I tried to argue for the same point but lacked the word “duality” in my corpus. Thank you, will use in the future!

2.2mm is an average. What happens is that in some places high tides are higher than that, along with the low tides.

“It’s snowing today so global warming is a hoax.”

weather ≠ climate

It blows my mind that to some people, 2.2mm isn’t a big deal. Seriously, the size of earth, the amount of coastlines, the amount of rivers connecting to the ocean, the snowballing effect on increased melting?

What is it that people don’t get?

Where did I say it was? Can you perhaps quote the part?

I’m just saying the mention / comparison you are making is very similar to that kind of rhetoric. Also, it doesn’t relate to the actual problem but can be used to undermine the seriousness if these values are true.

I suspect people think that along the lines of

A high tide causes floods, but that's like a 4000mm tide. What difference does it matter if it's 4002mm?

And they'd be mostly right - if it was just 2mm higher that wouldn't be an issue.

What's missing is

1) 2mm is average, some places it's far higher 2) 2mm in 2 months is 12cm in a decade, or 30cm after a 25 year mortgage
