There will be more days in the year when you can't walk barefoot on asphalt.

that's the big problem isn't it? how many days per year are we willing to give up walking barefoot on the asphalt?

Then there is me, who says that GW doesn't MATTER. It's just the latest in the series:

(Besides, it's not warming it's CLIMATE CHANGE. Can't you alarmists keep up with your own terminology?)

Doesn't matter? Well, if you live far away from the coast, I'm sure that could be true...for a little while.

I have friends in Brunswick, GA on the coast. At high tide, their lawn is 3 feet above the water.

Two questions for the GW know-it-alls here at BAUT:

So, how long do YOU think they have before their house gets wet at high tide?

How much has sea level rose in the past 15 years?

Well let's see, Coastal Georgia gets about 110 mm of rain in August which is quite a bit and high tide happens twice a day, so my guess is it won't be long at all before their house gets wet at high tide.

But if you mean how long before their house gets wet from seawater at high tide, well sea levels are projected to rise at an average of 1-9mm a year for the next century, so it will take a while for sea levels to rise 3 feet, however an increase in sea level puts their property at greater risk of indunation during storm surges and may cause erosion and other problems.

Roughly 45 mm, mostly due to thermal expansion of the oceans.

And I'm not a GW know-it-all, but thanks for complimenting the people here on BAUT on their knowledge. I like to think I make a useful contribution now and then.

My point made. That was easy.

And what's your point? That we can neglect long-term problems? Or that it's easy to rationalize away responsibility for short-term actions having long-term consequences?

My point was that worries about a sea level rise are stupid. A few mm's a year, PLEASE!

Disparaging comments are nice, but I'd be curious to know why a few mm a year is not worthy of concern.

It doesn't take too many years of that for populated islands to disappear or be rendered uninhabitable. That seems like a good reason to look into ways to prevent or mitigate rising sea levels. At the very least, worrying about it is hardly stupid.

The devil is indeed in the details, even the EPA in willing to admit that. Once again, as is the case with so much of the global warming quesin, the issue is one of insufficient data.

What sort of insufficient data is suggested by the existence of landmass rebound?

I am suggesting that those who rely on these instruments to show increases in sea level to support the theory of global warming need more and better data because these sensors are measuring more than sea level rise caused by increases in global sea level.

That answer your question??

No, because I'd need to know what part of the techniques that are used to assess global sea levels is called into question by the rebound.

Given that it appears to be a fairly well-known geological phenomenon, I find it really hard to believe that nobody who pays attention to the sea levels had thought of this yet. Therefore, the mere existence of rebound does not lead me to question the conclusions - I'd also like to see evidence that it has a serious potential to muss up the data and has not been accounted for.

Well... if they have, they should publish their evaluation and methods along with their work. Until they do, the data they present are suspect.

You can find it in IPCC WG1 AR4 chapter 5 section 5.
